NEC VT670 - Przeróbka, potrzebna pomoc w odczytaniu schematu.

Posiadam projektor NEC VT670. Projektor nie posiada lampy, i nie uruchamia się po podłączeniu do prądu ( nie zapalają się diody, brak reakcji) Myślę że padł zasilacz. Pomyślałem, że mógłbym go przerobić na: -zasilanie z własnego zasilacza, - Lampę led. (np 10w lub 100 w.) mam jedną i drugą, więc coś dobiorę Znalazłem schemat z service manual w internecie, jednak nie do końca jestem sobie w stanie poradzić z jego odczytaniem. A jak wiadomo w tego typu sprzęcie błąd popełnia się tylko raz ;) Generalnie chodzimi o to co połączyć żeby oszukać płytę główną przy połączeniu balastu (lampy nie będzie WCALE) i jak podłączyć (i gdzie) zasilanie, oraz jakie powinno mieć napięcie. No i czy to w ogóle ma sens. P.s. W załączniku service manual. Schemat na stronie 399

SAFETY PRECAUTIONS
During servicing carefully observe the following.
1. OBSERVE ALL PRECAUTIONS
Items and locations that require special care during servicing, such as the cabinet, chassis, and parts are labelled
with individual safety instructions. Carefully comply with
these instructions and all precautions in the instruction
manual.
2. BE CAREFUL OF ELECTRIC SHOCK
The chassis carries an AC voltage. If you touch the
chassis while it is still alive, you will get a severe shock.
If you think the chassis is alive, use an isolating
transformer or gloves, or pull out the plug before
replacing any parts.
3. USE SPECIFIED PARTS
The components have been chosen for minimum
flammability and for specific levels of resistance value
and withstand voltage. Replacement parts must match
these original specifications. Parts whose specifications
are particularly vital to safe use and maintenance of the
set are marked on the circuit diagrams and parts list.
Substitution of these parts can be dangerous for you
and the customer, so use only specified parts.
4. REMOUNT ALL PARTS AND RECONNECT ALL
WIRES AS ORIGINALLY INSTALLED
For safety, insulating tape and tubes are used
throughout, but some lift-off parts on the printed wiring
board require special attention.
All wires are positioned away from high-temperature and
high-voltage parts, and, if removed for servicing, they
must be retuned precisely to their original positions.

2-2

5. LAMP
Be very careful of the lamp because it generates high
heat while it is used at high voltage. When replacing
the bulb, make sure it is cool enough.
6. LENS
Do not look into the lens during projection. This important
to avoid damage to the eyes.
7. SERVICING
At the time of repair or inspection services, use an earth
band (wrist band), without fail.
8. RUN A COMPLETE SAFETY CHECK AT THE
COMPLETION OF SERVICING
After completion of servicing, confirm that all screws,
parts, and wiring, removed or disconnected for servicing,
have been returned to their original positions. Also
examine if the serviced sections and peripheral areas
have suffered from any deterioration as a result of
servicing. In addition, check insulation between external
metallic parts and blades of wall-outlet plugs. This
examination is indispensable in confirming complete
establishment of safety.
(Insulation check)
Pull out a plug from a wall outlet to disconnect the
connection cable. Then turn on the POWER switch.
Use a 500V megger (Note 2) and confirm that the
insulation resistance is 1MΩ or more between each
terminal of the plug and exposed external metal (Note
1). If the measured value is below the specified level,
then it is necessary to inspect and fix the set.
(Note 1)
Exposed external metal....RGB input terminals, control
terminals, etc.
(Note 2)
If a 500V megger is not available for an unavoidable
reason, then use a circuit tester or the like for inspection.

Important Information
Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside
your projector. Allow at least 4 inches (10 cm) of space between your projector and a wall.
2. Prevent foreign objects such as paper clips and bits of paper from falling into your projector.
Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as
a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately
and have the object removed by a qualified NEC service personnel.
3. Do not place any liquids on top of your projector.
4. Do not look into the lens while the projector is on. Serious damage to your eyes could result.
5. Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the
lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can
cause unpredictable outcome such as fire or injury to the eyes.
6. Do not cover the lens with the supplied lens cap or equivalent while the projector is on. Doing so can lead to
melting of the cap and possibly burning your hands due to the heat emitted from the light output.
7. Do not place any objects, which are easily affected by heat, in front of the projector lens or a projector exhaust
vent.
Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the
light output and exhaust.
8. The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power
supply fits this requirement before attempting to use your projector.
9. Handle the power cable carefully and avoid excessive bending.
A damaged cord can cause electric shock or fire.
10. If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet.
11. Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.
12. Do not handle the power plug with wet hands.
CAUTION
• Do not try to touch the ventilation outlet on the left side (when seen from the front) as it can become heated
while the projector is turned on.
• Do no use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt-foot or
hanging on the wall can cause damage to the projector.
• When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle
to the projector cabinet are tight. (VT676/VT670/VT470 only)
Insufficient tightening of the two screws could result in the projector falling and causing injury.
• Do not send the projector in the soft carrying case by parcel delivery service or cargo shipment. The projector
inside the soft carrying case could be damaged.
• Select [High] in Fan mode if you continue to use the projector for consecutive days. (From the menu, select
[Advanced] → [Fan Mode] → [High].)
• Do not unplug the power cable from the wall outlet under any one of the following circumstances.
Doing so can cause damage to the projector:
* While the Hour Glass icon appears.
* While the cooling fans are running. (The cooling fans continue to work for 30 seconds after the projector is
turned off).

iii

Important Information
Lamp Replacement


To replace the lamp, follow all instructions provided on page 50.



Be sure to replace the lamp when the message “The lamp has reached the end of its usable life. Please
replace the lamp.” appears. If you continue to use the lamp after the lamp has reached the end of its usable
life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch them as the
pieces of glass may cause injury.

2. Installation and Connections
• Ensure that you have adequate ventilation around your
projector so heat can dissipate. Do not cover the vents
on the side or the front of the projector.

WARNING
* Installing your projector on the ceiling must be done
by a qualified technician. Contact your NEC dealer for
more information.
* Do not attempt to install the projector yourself.
• Only use your projector on a solid, level surface. If the
projector falls to the ground, you can be injured and
the projector severely damaged.
• Do not use the projector where temperatures vary
greatly. The projector must be used at temperatures
between 41˚F (5˚C) and 95˚F (35˚C).
• Do not expose the projector to moisture, dust, or
smoke. This will harm the screen image.

Reflecting the Image
Using a mirror to reflect your projector's image enables
you to enjoy a much larger image. Contact your NEC
dealer if you need a mirror system. If you're using a mirror system and your image is inverted, use the MENU
and SELECT buttons on your projector cabinet or your
remote control to correct the orientation. See page 41.

2. Installation and Connections

ᕢ Making Connections
NOTE: When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the
power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook PC is turned on after
connecting with the projector.
* If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power
management software.

Enabling the computer’s external display
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector.
When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come on
or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through
external display selections.

Connecting Your PC or Macintosh Computer
NOTE: • VT676/VT670/VT575/VT470: The COMPUTER 1 connector supports Plug & Play (DDC2).
• VT47: The COMPUTER connector supports Plug & Play (DDC2).

6. Maintenance
This section describes the simple maintenance procedures you should follow to clean the filter and replace the lamp.

ᕡ Cleaning or Replacing the Filter
The air-filter sponge keeps dust and dirt from getting inside the projector and should be cleaned after every 100 hours
of operation (more often in dusty conditions). If the filter is dirty or clogged, your projector may overheat.

CAUTION


Turn off the projector, turn off the main power switch and unplug the projector before replacing the filter.



Only clean the outside of the filter cover with a vacuum cleaner.



Do not attempt to operate the projector without the filter cover.

6. Maintenance

» Replacing the Lamp
After your lamp has been operating for 2000* hours (up to 3000* hours in Eco mode) or longer, the LAMP indicator in
the cabinet will blink red and the message “The lamp has reached the end of its usable life. Please replace the
lamp.” will appear. Even though the lamp may still be working, replace it at 2000* (up to 3000* hours in Eco mode)
hours to maintain optimal projector performance. After replacing the lamp, be sure to clear the lamp hour meter. See
page 47.

CAUTION


DO NOT TOUCH THE LAMP immediately after it has been used. It will be extremely hot. Turn the projector off,
wait 30 seconds, turn off the main power switch and then disconnect the power cable. Allow at least one hour
for the lamp to cool before handling.



DO NOT REMOVE ANY SCREWS except two lamp case screws. You could receive an electric shock.



Do not break the glass on the lamp housing.
Keep finger prints off the glass surface on the lamp housing. Leaving finger prints in the glass surface might
cause an unwanted shadow and poor picture quality.



The projector will turn off and go into standby mode after 2100* (up to 3100* hours in Eco mode) hours of
service. If this happens, be sure to replace the lamp. If you continue to use the lamp after 2000* hours (up to
3000* hours in Eco mode) of use, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp
case. Do not touch them as the pieces of glass may cause injury. If this happens, contact your NEC dealer for
lamp replacement.

*NOTE: Lamp life for VT575/VT47 is 3000 hours in Normal mode and 4000 hours in Eco mode.
The projector will turn off and go into standby mode after 3100 (up to 4100 hours in Eco mode) hours of service.
To replace the lamp:
Optional lamp and tools needed for replacement:
• Replacement lamp VT75LP (VT676/VT670/VT470) or VT70LP (VT575/VT47)

7. Appendix
If there is no picture, or the picture is not displayed correctly.


Power on process for the projector and the PC.
Be sure to connect the RGB cable between the projector and the computer before turning on the computer.
There are some notebook PCs, which do not output signal unless there is a projector or monitor connected first.

NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information. If it reads
“0kHz”, this means there is no signal being output from the computer. See page 46 or go to next step.


Enabling the computer’s external display.
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector. When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come
on or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle
through external display selections.



Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use.
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the
previous step. Refer to your computer’s documentation for detailed information.



Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projector) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
For setting display modes other than those supported by your Macintosh and the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the DIP
switch to the 13” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a
displayable mode and then restart the Macintosh again.

NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini D-Sub
15-pin connector.


Mirroring on a PowerBook
* When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirroring” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.



Folders or icons are hidden on the Macintosh screen
Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange] from the Apple
menu and arrange icons.

Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside
your projector. Allow at least 4 inches (10 cm) of space between your projector and a wall.
2. Prevent foreign objects such as paper clips and bits of paper from falling into your projector.
Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as
a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately
and have the object removed by a qualified NEC service personnel.
3. Do not place any liquids on top of your projector.
4. Do not look into the lens while the projector is on. Serious damage to your eyes could result.
5. Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the
lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can
cause unpredictable outcome such as fire or injury to the eyes.
6. Do not cover the lens with the supplied lens cap or equivalent while the projector is on. Doing so can lead to
melting of the cap and possibly burning your hands due to the heat emitted from the light output.
7. Do not place any objects, which are easily affected by heat, in front of the projector lens or a projector exhaust
vent.
Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the
light output and exhaust.
8. The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power
supply fits this requirement before attempting to use your projector.
9. Handle the power cable carefully and avoid excessive bending.
A damaged cord can cause electric shock or fire.
10. If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet.
11. Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.
12. Do not handle the power plug with wet hands.
CAUTION
• Do not try to touch the ventilation outlet on the left side (when seen from the front) as it can become heated
while the projector is turned on.
• Do no use the tilt-foot for purposes other than originally intended. Misuses such as gripping the tilt-foot or
hanging on the wall can cause damage to the projector.
• When carrying the projector by the carrying handle, make sure the two screws that attach the carrying handle
to the projector cabinet are tight. (VT676/VT670/VT470 only)

E-11

If there is no picture, or the picture is not displayed correctly.


Power on process for the projector and the PC.
Be sure to connect the RGB cable between the projector and the computer before turning on the computer.
There are some notebook PCs, which do not output signal unless there is a projector or monitor connected first.

NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information. If it reads
“0kHz”, this means there is no signal being output from the computer. See page 46 (User’s Manual) or go to next step.


Enabling the computer’s external display.
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector. When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come
on or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle
through external display selections.



Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use.
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the
previous step. Refer to your computer’s documentation for detailed information.



Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projector) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
For setting display modes other than those supported by your Macintosh and the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the DIP
switch to the 13” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a
displayable mode and then restart the Macintosh again.

NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini D-Sub
15-pin connector.


Mirroring on a PowerBook
* When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirroring” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.



Folders or icons are hidden on the Macintosh screen
Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange] from the Apple
menu and arrange icons.

2. Installation and Connections
• Ensure that you have adequate ventilation around your
projector so heat can dissipate. Do not cover the vents
on the side or the front of the projector.

WARNING
* Installing your projector on the ceiling must be done
by a qualified technician. Contact your NEC dealer for
more information.
* Do not attempt to install the projector yourself.
• Only use your projector on a solid, level surface. If the
projector falls to the ground, you can be injured and
the projector severely damaged.
• Do not use the projector where temperatures vary
greatly. The projector must be used at temperatures
between 41˚F (5˚C) and 95˚F (35˚C).
• Do not expose the projector to moisture, dust, or
smoke. This will harm the screen image.

Reflecting the Image
Using a mirror to reflect your projector's image enables
you to enjoy a much larger image. Contact your NEC
dealer if you need a mirror system. If you're using a mirror system and your image is inverted, use the MENU
and SELECT buttons on your projector cabinet or your
remote control to correct the orientation. See page 37.

2. Installation and Connections

ᕢ Making Connections
NOTE: When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning on the
power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook PC is turned on after
connecting with the projector.
* If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver or power
management software.

Enabling the computer’s external display
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector.
When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come on
or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through
external display selections.

7. Appendix
If there is no picture, or the picture is not displayed correctly.


Power on process for the projector and the PC.
Be sure to connect the RGB cable between the projector and the computer before turning on the computer.
There are some notebook PCs, which do not output signal unless there is a projector or monitor connected first.

NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information. If it reads
“0kHz”, this means there is no signal being output from the computer. See page 42 or go to next step.


Enabling the computer’s external display.
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector. When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come
on or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle
through external display selections.



Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use.
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the
previous step. Refer to your computer’s documentation for detailed information.



Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projector) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
For setting display modes other than those supported by your Macintosh and the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the DIP
switch to the 13” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a
displayable mode and then restart the Macintosh again.

NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini D-Sub
15-pin connector.


Mirroring on a PowerBook
* When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirroring” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.



Folders or icons are hidden on the Macintosh screen
Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange] from the Apple
menu and arrange icons.

Fire and Shock Precautions
1. Ensure that there is sufficient ventilation and that vents are unobstructed to prevent the build-up of heat inside
your projector. Allow at least 4 inches (10 cm) of space between your projector and a wall.
2. Prevent foreign objects such as paper clips and bits of paper from falling into your projector.
Do not attempt to retrieve any objects that might fall into your projector. Do not insert any metal objects such as
a wire or screwdriver into your projector. If something should fall into your projector, disconnect it immediately
and have the object removed by a qualified NEC service personnel.
3. Do not place any liquids on top of your projector.
4. Do not look into the lens while the projector is on. Serious damage to your eyes could result.
5. Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the
lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can
cause unpredictable outcome such as fire or injury to the eyes.
6. Do not cover the lens with the supplied lens cap or equivalent while the projector is on. Doing so can lead to
melting of the cap and possibly burning your hands due to the heat emitted from the light output.
7. Do not place any objects, which are easily affected by heat, in front of the projector lens or a projector exhaust
vent.
Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the
light output and exhaust.
8. The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power
supply fits this requirement before attempting to use your projector.
9. Handle the power cable carefully and avoid excessive bending.
A damaged cord can cause electric shock or fire.
10. If the projector is not to be used for an extended period of time, disconnect the plug from the power outlet.
11. Do not touch the power plug during a thunderstorm. Doing so can cause electrical shock or fire.
12. Do not handle the power plug with wet hands.
CAUTION
• Do not try to touch the ventilation outlet on the left side (when seen from the front) as it can become heated

If there is no picture, or the picture is not displayed correctly.


Power on process for the projector and the PC.
Be sure to connect the RGB cable between the projector and the computer before turning on the computer.
There are some notebook PCs, which do not output signal unless there is a projector or monitor connected first.

NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information. If it reads
“0kHz”, this means there is no signal being output from the computer. See page 42 (User’s Manual) or go to next step.


Enabling the computer’s external display.
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector. When using a PC compatible laptop, a combination of function keys will enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come
on or off. For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle
through external display selections.



Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use.
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the
previous step. Refer to your computer’s documentation for detailed information.



Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projector) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
For setting display modes other than those supported by your Macintosh and the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the DIP
switch to the 13” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a
displayable mode and then restart the Macintosh again.

NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini D-Sub
15-pin connector.


Mirroring on a PowerBook
* When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirroring” is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.



Folders or icons are hidden on the Macintosh screen
Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange] from the Apple
menu and arrange icons.

6-4. Auto-adjust position change

When auto adjustment is intended for [Sub-B/C] by means of the [Auto] button, such an adjustment can
be carried out by reading out the level data of the predetermined position in the screen.
Since this read-out position can differ according to the adjusting mode and color, all patterns, resolution,
and other factors are specified and set in the relevant positions in advance. Therefore, no particular
modification is required in general operation.
Automatic adjustment is impossible, however, where a similar pattern is allocated in a slightly different
position.
In such a case, setting can be carried out according to the descriptions below.
Adjustments become impossible if a wrong position is set up.
There are upper limits for the readout position. Since a message is displayed, make settings within the
indicated possible range.
& lt; Read & gt;
This function is used to look for a position being modified.
Enter a position input in the [H], [V] editor.
The numeral to be entered is decimal. The guidelines are the number of dots for [H] and the number of
lines for [V] (half in case of interlace).
When the [Read] button is clicked, the signal level of the specified position is displayed for R/G/B, respectively.
This value is displayed within the range of 0 (black) - 255 (white).
Based on this figure, confirm where the specified position is located on the screen and look for the
position to be used for adjustment.

• Cancel: Test pattern cancel
3.3.2. Sync Protection
It is possible to make adjustments of Upper and Lower.
IC AD9883A, intended for the A/D conversion of RGB signals, has a function to generate the sampling
clock for A/D conversion from HSYNC that is entered in the A/D.
Actually, the HSYNC signal is divided at the dividing ratio that has been preset, so that the resultant
frequency can be compared with the frequency that is gained from VCO oscillation. The differential
signal is fed back to the VCO so that the VCO frequency can be kept to be constant and synchronized
with the HSYNC signal. (In short, a PLL effect is given to the HSYNC signal.)
At that time, however, the operation of feedback to the VCO may be wrongly performed and the
oscillation frequency of the VCO may deviate from the intended frequency if the pulse intervals of
HSYNC are wrongly changed due to the effect of equivalent pulses and incoming pulses of the HSYNC
signal.
This function has been provided to avoid such a difficulty. With this function, a period is set up to
suspend feedback operation to the VCO.
In regard to the adjusting range, the front side is defined as the UPPER side and the rear side as the
LOWER side, based on the VSYNC.

SERVICEMAN MODE
Practically, adjustments are made in the setting position where no malfunction occurs even though the
screen should give rise to any difficulty such as upper screen bend or the like.
3.3.3. VS Bbegin
In the PW164B, the line position and other factors to start up the display are defined based on the
timing at which the entered H sync input is transferred to the V sync mode.
The VS Begin is the circuit that determines the threshold value of the above-mentioned timing at which
H sync is switched over to V sync.
If the changeover timing from H sync to V sync seems to affect the signal display, such a problem can
be solved by adjusting the VS Begin circuit.
The phenomena, for which the effect of adjustment can be expected, are shown below.
• The screen sways in the V direction.
• The line is reversed by an interlace signal.
For reasons of some signal conditions or others, the above-mentioned improvements may fail to be
accomplished.
To obtain a better result, adjustments should be carried out where no deficiencies may arise.
3.3.4. Clamp Timing
Used to adjust clamp timing for the HSYNC signal.
If the clamp timing does not match the video start timing for the H sync signal input or if it does not
match the end-of-sync timing for the Sync on Green signal, clamping may be carried out in the middle
of video period and a black belt may be generated in vertical direction. In another case, an error may
be caused in brightness because clamping is conducted in the middle of sync period.
Adjustments should be made in a position where no malfunction occurs.
* This function is not available if there is an input of [Component Signal] or [Video Signal].
3.3.5. Remote Sensor
Setting is made to determine whether the receiver of the remote control is used or not used.
This function enables that the selected mode becomes effective when closing the menu displaying the
options.
Setting

Function

Front/Rear

Both of the light receiving blocks in the front and rear of the set are used.

Front

Only the light receiving block in the front of the set is used.

Rear

Only the light receiving block in the rear of the set is used.

3.3.6. Message
Display or non-display of the following messages is set up:
Function error: [This function cannot be used.]
Cabinet button lock: [Keys of the main unit are now locked.]
Power management: [It is 3 minutes before power OFF.]
Sleep timer: [It is 3 minutes before power OFF.]
The initial value is ON after Factory Default.

3.3.7. Frame Lock
This function is intended to make the vertical sync frequency (frame rate) of LCD panel driving match
the vertical sync frequency (frame rate) of the input signal. When the signal side (initial value) is
selected, a state of Frame Lock is assumed in regard to a signal of the vertical frequency (frame rate)
60Hz or 50Hz where the presence of motion pictures is anticipated. Therefore, if operation for Frame
Lock is performed, it is possible to avoid the occurrence of partial cutoff in motion pictures.

6-4

“Confidential, Do Not Duplicate without written authorization from NEC.”

SERVICEMAN MODE
In the state of Frame Lock, the vertical sync frequency (frame rate) is lower than that of the signal for
which Frame Lock is not performed. If it is necessary to accomplish some improvements against such
flicker deterioration, setting for Frame Lock should be changed over to the OFF side. In such a case,
however, partial cutoff in motion pictures can occur when such motion pictures are displayed.
In conclusion, a decision must be made in regard to whether operation for Frame Lock is carried out
on the setup (signal) side or on the OFF side for the signals that are applied to the Computer terminal.
If input changeover or signal changeover is conducted after the modification of Signal/Off setup, operation is performed according to the setup data.

3.4. Service Menu
3.4.1. Check Start
This function is used to measure the values in horizontal state for auto trapezoidal correction or the
internal temperatures for temperature correction. This measurement should be carried out in the horizontal state, without fail.
The present value is checked and displayed in about 2 seconds. When the ENTER key is pressed,
this measurement is started and an hourglass is displayed on the screen.
When the measurement is over, a menu is displayed and the counted value is displayed in the item of
Change Offset.
3.4.2. Change Offset
This function is used to set up the values in the main unit. These values are the data measured in
horizontal state or the internal temperatures measured for temperature correction. If 0 is indicated, this
means that no measurement is carried out yet.
If any value other than “0” is displayed, the displayed value can be set up in the main unit when the
ENTER key is pressed. After the completion of operation, a menu is displayed and Value 0 is displayed.
The value set up in the main unit is displayed in the item of Offset.
3.4.3. Offset
This function is used to indicate the values obtained in horizontal state where the main unit is currently
used, or to display the internal temperatures for temperature correction.
After the completion of measurements for auto-trapezoidal compensation, cancel “Auto Keystone” of
“Image” in the menu and then turn it ON again. At the time of changing from OFF to ON, the keystone
data are updated at the preset value.
The above-mentioned menu operation is not always required. Though a new setting value is used
internally, no additional compensation is carried out until a change is sensed in the gradient from the
gradient sensor. Therefore, so long as video images are observed, it seems as if no reflection had
been made in regard to the adjusting value.
In cases other than the above-mentioned menu operation, shaking the main unit or making a restart
operation by turning off the power source can be reflected on the state of projection.
3.4.4. Color Uniformity
ON/OFF switching is conducted for the correction of color unevenness.
When the OPT base or the like is replaced, color unevenness may be increased on the contrary if the
data before replacement are used as the correction data for color unevenness. Accordingly, this function is used to check the state of correction and others. These setup data are not stored in the internal
memory of the projector.

This is a security function similar to that of the VT60 Series.
• Keyword setting only is required for security. (The memory card cannot be used.)
• The keyword is a combination of the UP, DOWN, RIGHT, and LEFT keys.

4.1 How to cancel the security functions
If the user forgets the keyword and cannot use the projector, it is necessary to make queries to the service
station to get the keyword, in the same manner as for the VT60 Series.
This procedure is the same as for the VT60 Series. The same security-canceling tool is used.
For the security-canceling tool, the decoded keyword is indicated in alphanumerical characters. Since the
keyword for this model uses the up/down/right/left keys, it is necessary to decode the indicated alphanumerical
characters into such up/down/right/left keys.
When the keyword indicated by the security-canceling tool has to be transferred to the user, refer to the next
table and decode the numerals into the up/down/right/left keys.

Input processor block (Input block, A/D converter, PLL)
The video signal inputs entered in Computer 1 (mini D-SUB, Pin 15) and Computer 2 (mini D-SUB, Pin 15)
are selected at the selector NJM2584 (IC9003) at user’s choice and transferred to the A/D converter PW2200B
(IC2001) via the buffer and the LPF. The LPF block has two types of filters that can be changed over by the
user. (No selector is provided to the VT37/VT47.) The video signals are converted into the 2-layer decoded
8-bit digital signals by the A/D converter. The converted signals are output to the PW164B (IC3006). The
signals (clamp pulses , mask pulses), intended to clamp the video signals that are needed inside the A/D
converter PW2200B (IC2001), are generated in the PW164B (IC3006) and output to the A/D converter. The
A/D converter is provided with a built-in PLL circuit. The clock signals locked at the H sync signal and the
timing pulses are output to the PW164B (IC3006).
Control of the A/D converter PW2200B (IC2001) is carried out at I2C by the PW164B (IC3006).

After the termination, the Composite video signals are entered in the A/D converter PW2200B (IC2001). In
this circuit, the video signals are decoded into the digital signals, which are then output to the PW164B
(IC3006) together with the sync signal.
Control of the A/D converter PW2200B (IC2001) is carried out at I2C by the PW164B (IC3006).

3-4.

RGB output processing
When terminated at 75Ω, the video signals selected at the selector NJM2584 (IC9003) at user’s choice are
maintained at 1Vp-p and output after passing through the 6dB AMP (IC9004).
The H sync signal passes through the buffer circuit (Q9005, Q9008) and is then output.
The V sync signal passes through the buffer circuit (Q9014, Q1015) and is then output.

3-5.

Plug & Play
The V Sync circuit of Computer 1 (mini D-SUB, Pin 15) and the serial terminals of Pins 12 and 15 are
connected to the Plug & Play IC circuit (IC9001: TC9WMB1FK) so that the projector can be picked up at the
personal computer.
(No Plug & Play function is provided to the Computer 2 terminal.)

3-6.

Audio I/O processing
The audio signal input is entered in the output amplifier IC (IC9502: LM4871MX) via the audio processor IC
(IC9501: NJW1141M). Usually, an internal speaker (8Ωx1) is used. In this case, the audio signal output is a
mixture of Signal R and Signal L (1W MAX.). When the output amplifier circuit is connected to the AUDIO
OUT terminal, the internal speaker is muted and the audio output is available only at the AUDIO OUT terminal. In this case, stereo signals are output. The volume control is effective even when the AUDIO OUT
terminal is used.
Volume control is effected at the audio processor IC. In this case, I2C control is carried out with the aid of the
PW164B (IC3006).

Protector
If any one of the conditions below is sensed, the projector causes the status LED to flash and the standby
status is recovered.
• Sensed when the lamp cover is removed
• Detection of fan (x 4) stoppage
• Detection of lamp non-lighting
• Detection of fan rpm control and abnormal temperature by temperature sensor

3-8.

PW164B (IC3006) (CPU, video signal processor)
The PW164B (IC3006) is an LSI where the CPU and the video signal processor circuit are combined. In this
LSI, various controls are carried out, such as conversion of resolution, keystone correction, frame rate conversion, OSD output processing, and such video signal processing plus projector control.
Programs and data used in the CPU are stored in the 8-Mbit FLASH ROM (IC3005) and the EEPROM
(IC3003).
The RGB signals, the Component signals, and the Video signals are the 2-layer decoded 8-bit digital video
outputs obtained from the A/D converter PW2200B (IC2001). These outputs are entered in the graphic port
(GPORT) of the PW164B (IC3006).
In the PW164B circuit, two types of clock signals are used; 120MHz and 65MHz (Model XGA) or 43MHz
(Model SVGA). The 120MHz clock signal is used in the CPU block (3-frequency division internally) and in the
internal SDRAM. The 65MHz or 43MHz clock signal is used in the video output block. Each clock signal is
generated in the clock generator IC (IC3007: ASM3P2508) and entered in the UNISEVEN (IC5001). The 8bitx3 video signals, which are output from the PW164B (IC3006), are directly applied to the UNISEVEN
(IC5001).
The digital zoom function (VT37/VT47) is realized through the scaling process of the PW164B.

3-9.

UNISEVEN
The UNISEVEN circuit (IC5001) is an ASIC block where various correction functions and other important
functions such as LC timing signal generation, etc., are incorporated.
• V-T correction
• Color unevenness correction
• Color correction
• Generation of timing signals for LC panel driving
• LC panel driving compensation (ghost, vertical lines)
The video input signals entered from the PW164B (IC3006) into the 8-bitx3 video signal circuit pass through
the various corrector circuits of V-T correction, color unevenness correction, color correction, wall color
correction, etc. and are then output to the 6-phase decoding AD8381 IC block (IC6001~3) in the 10-bitx3
mode. The timing signals for LC panel driving are output to the level shift circuit ADSY8401 (IC6501, 6502).
(For the VT47, level shift effected in IC6801~3) In the V-T corrector block, the video input signals are converted into the data according to the LC panel characteristics specified in the lookup table. The color unevenness corrector block has the brightness data for each 25x20 split screen. In this block, the video data are
operated and processed so that a uniform screen can be obtained as a whole. In the color corrector block,
the picture management function is utilized. For the wall color correction, hue conversion processing is
carried out for the wall correction feature.
The UNISEVEN circuit is controlled in such a manner that the address-mapped registers in the UNISEVEN
circuit are controlled by the PW164B (IC3006).

3-10. TIGHT CELL
The Tight Cell circuit (IC4002) is a G/A block where the various functions of fan control, key matrix, LED
control, etc., shown below, are incorporated. The Tight Cell circuit is controlled by the PW164B (IC3006)
through the CPU bus.
• Reset free circuit
When a power supply supervisory reset signal input is entered from the reset IC (IC4001), the reset signal
is output to each device after the removal of noise by filter processing.
• Fan control (5 systems)
The four systems are used for fan control. According to the rpm pulse signal output from the fan, the rpm
level is sensed. Based on the temperature data detected from the temperature sensor AD7417 (IC3001),
the fan rpm level is controlled so that each part of the fan can maintain its optimal temperature.

CIRCUIT DESCRIPTION
The remaining one system is used to generate a beep sound in case when the relevant button key is
pressed or at the time of the occurrence of an error.
• Key matrix control
• General-purpose I/O port
Used for the lighting control of each LED and for the control of each IC.
• UART control
Used for lamp’s power setup and for the acquisition of the operational status.
3-11. Video output processor block
The “10-bit x 3” video signal input entered from the UNISEVN (IC5001) is processed for the D/A conversion
and the level conversion at the LCD panel driver IC (IC6001-3). These signals are fed to the LCD panel after
the signals have been restored to the respective analog RGB signals (10Vp-p) of 6 phases each.
The timing signals for LCD panel driving are converted into the voltages (15.5Vp-p or 5Vp-p) needed to drive
the shift register in the LCD panel. This signal conversion is effected by the level shift IC (IC6501-2 or
IC6801-3). The obtained voltages are applied to the LCD panel. Part of the signals (uniformity improving
signal) for LC driving are supplied to the LCD panel through the buffer circuit of transistors. The voltage used
in common for the LCD panel is extended to each panel of RGB by the use of Channel 3 of the 4-ch serial D/
A (IC6004: M62334FP).
3-12. Auto-trapezoid correction processing (The VT37 is not applicable because it has no function of automatic trapezoid compensation.)
The gradient of the projector is detected by the gravity acceleration sensor (IC3002). This detection is intended for the automatic adjustment of the trapezoidal condition (keystone).
The gravity acceleration sensor generates a DC voltage output in compliance with the gradient of the projector. The output voltage is applied to the A/D converter terminal of the temperature sensor (IC3001). The data
received at the A/D converter are read out via the I2C bus and operational processing is executed at the
PW164B (IC3006).
3-13. I2C data bus control
The PW164B (IC3006) has two systems of I2C bus interfaces. The six devices specified below are controlled
from each interface.
• I2C BUS I/F1 (BUS No. 1): Normal operation
• I2C BUS I/F2 (BUS No. 2): In operation only in the period of power-ON.

Classification of components and roles
The roles (functions) of optical components are as specified below.
Each component comes in a multi-functional component where multiple functions
are available.
1. Illumination function: (illumination)

This function is that light is produced to illuminate the liquid crystal by
controlling the illumination distribution.
[ LAMP, REFLCTER, INTEGRATOR, PBS : Polarized Beam Splitter,
FIELD LENS, CONDENSER LENS, RELAY LENS ]

2. Color separation and synthesis function : (color)
White light is separated into R,G,B and the separated R, G, B rays are
synthesized again.
[ LAMP, DICHROIC MIRROR, CROSS PRISM : XDP, POLARIZER,
Liquid crystal panel , ANALYZER ]

3. Projection function: (projection)
A small LC image is enlarged and projected at a large screen.
[ Liquid crystal panel, ZOOM LENS]

4. Reliability and safety control function: (trustworthiness)
Reliability and safety are assured.
[REFLCTER, INTEGRATOR, IR MIRROR, PBS : Polarized Beam Splitter,
UV CUT FILTE ]

5. Polarization control function: (polarization)
The polarization of light is controlled.
[ PBS :Polarized Beam Splitter, POLARIZER, ANALYZER, Liquid crystal
panel ]

6. Direction control function: (direction)

Components and roles
[LAMP]: [illumination][color]
This component is intended to generate the light inside the PJ.
It is composed of a quartz bulb and tungsten electrodes, from which the light is
generated by the effect of discharges.
According to the type of a material (mercury, etc.) put in the bulb, the emission
spectrum changes.
While the lamp is glowing, the electrodes in the bulb are heated at a temperature
of some thousand degrees centigrade. Even the bulb surface is heated at a high
temperature of 1000 degrees centigrade.
BULB

17-10

[REFLCTER]: [illumination][direction][trustworthiness]
This is a reflection mirror where the light generated in the lamp is collected and
projected forward.
The shape of the reflector comes in a parabolic form or an oval form.
The roles of the reflector are as follows.
(1) Light is collected and projected forward. (Reflection mirror)
(2) The infrared rays are not projected forward. (A cold coat is provided.)
→The infrared rays pass by behind the projector.
(3) It has a role of protection when the lamp is broken.
→This glass has a mechanical strength that is stronger than ordinary glass.
(4) It has a role of holding the lamp.

REFLCTER

17-11

[Cover glass]: [trustworthiness]
It has a role of protecting parts in the engine when the lamp is broken or
preventing the scattering of fractions.
Its surface is generally provided with an AR coat of Pyrex, etc. The glass used has
a high mechanical strength and a high durability against heat.
For the parts to be protected against lamp fracture, the glass thickness is 3 to 5mm.

17-12

[AR coat]
The glass surface used for the projector is always coated.
The AR coating (Anti-Reflection coating) is typical.
By suppressing the reflection from the glass surface, the transmission factor can be
raised.

[INTEGRATOR]: [illumination][trustworthiness]
The light source (lamp) can be made into the multiple type. This component can
assure the unified radiation of the LCD panel.
Generally, it comes in a composition of Integrator 1 and Integrator 2.A combination
of single lenses called the field lens comes after it.
In some cases, Integrator 1 may have an evaporation of UV coating or UV-IR
coating.

[PBS]: [illumination][polarization][direction]
PBS is an acronym of the Polarized Beam Splitter. (General name)
It is a sort of prism with the function of splitting the non-polarized beam into Rays
S and Rays P.
After splitting into the S/P rays, the PBS used for the projector permits either rays
to be transmitted through the phase differential plate so that the optical efficiency
can be raised through the alignment of the polarized rays.

[Polarized rays S and P]
The outgoing light from the lamp is a “random” beam without any polarization.
If the PBS or the like is used for transmission and reflection, it is possible to
obtain the polarized rays S and P, where vibration of light is aligned in the same
direction.
Polarized rays P: Parallel

Polarized rays S: Vertical
The polarization is defined based on the reflection
plane.

Polarized rays P
Plane of incidence

Polarized rays S

When the light enters the reflection plane, the
plane is called the plane of incidence where the
perpendicular line on the reflection plane and the
incident light are included.
The polarized rays S are the polarization whose
vibrating direction of the light (electric field) is
perpendicular to the plane of incidence.

Reflection plane

The polarized rays P are the polarization whose
vibrating direction of the light is parallel to the plane
of incidence.
17-17

[DICHROIC MIRROR]: [color] [direction]
A component of a flat glass plate provided with a dichroic coating is called the
dichroic mirror (filter).
The dichroic coating has a function of dividing colors in such a manner that
white color is divided into monochromic colors of red and blue or a color
mixture of yellow, cyan, etc.
In many cases, the dichroic mirror used for the projector is placed at an angle
of 45 degrees. Since it establishes the reflection (transmission) characteristics
for the incident angle of 45 degrees, the DM for the transmission of “red only”
in the projector functions as a filter. Therefore, a fluorescent lamp does not
look red.

[MIRROR, FILTER and PRISM]
The projector components have the names of ****** MIRROR and ****** FILTER.
The IR (coating) filter and the IR (coating) mirror are the examples. These names
indicate the difference between mirror and filter or prism.

Offset

When the light passes
through an object, such an
item is called the FILTER.

When the light is reflected
at an object, such an item
is called the MIRROR.

Light

A polyhedron made of
glass is called the PRISM.

The light passing through the MIRROR is attached
with an offset in conjunction with the incident light.
However, the light passing through the PRISM has
no offset. (For the cube type)
17-19

[Wedge coating]
The category of dichroic coating involves a somewhat specific coating called
the wedge coating. The dichroic mirror used to separate colors in the projector
generally has a characteristic of color separation in conjunction with the
incident light at 45 degrees. (The specification is based on the incident angle of
45 degrees.)
In actual projectors, however, beams in a spread mode pass through the
dichroic mirrors and some of them are partially transmitted at 45 degrees or 30
degrees, or 60 degrees.
The dichroic mirror has a characteristic of incident angle dependency.
Therefore, the cutoff wavelength for color separation can change according to
the incident angle. This characteristic gives rise to problems such as color
unevenness, brightness unevenness, hue unevenness, and others.
To solve the problems of color unevenness, etc., the dichroic mirrors have
tended to use wedges recently. However, there is a rise in cost in comparison
with ordinary dichroic mirrors. Therefore, careful examination is needed to
specify the effect of investment.

[UV FILTER]:

[trustworthiness]

The LCD panels and the polarization plates are degraded by ultraviolet (UV) rays.
Recently, not only the effect of ultraviolet rays but also that of visible rays of
about 420nm began to be indicated.
The UV absorption (UV reflection) filters began to be used to prevent the beams
of such a wavelength domain from approaching the LCD panel.
Since the projector uses the UV filter and the IR filter in the proximity of the lamp,
two UV filters are actually used in the unit.

17-22

[UV absorption filter and UV reflection filter]
The UV (R) absorption glass and the UV (R) reflection glass offer the differences as
described below.
& lt; Heat rays (R) absorption glass & gt;
This glass contains a very small quantity of metals such as nickel, iron, cobalt, etc.
It efficiently absorbs the light of wavelength near infrared rays that have a large quantity
of heat to suppress the temperature rise.
& lt; UV absorption glass & gt;
This glass contains a material that absorbs ultraviolet rays.
→The UV absorption glass is a specific type of glass where a material is contained
to absorb the objective wavelength.
& lt; Heat rays (R) reflection glass & gt;
This glass is coated with a thin metallic membrane on the surface.
In reverse to the heat rays absorption glass, this glass reflects the light of wavelength
near infrared rays that have a large quantity of heat to suppress the temperature rise.
& lt; UV reflection glass & gt;
This glass is coated with a thin metallic membrane on the surface.
→The reflection glass is coated with a thin membrane on the glass surface by
evaporation. It is a sort of the dichroic filter (mirror) that reflects the objective
17-23
wavelength. The glass to be used is a general white plate or the like.

[Condenser lens] :[illumination][projection][direction]
Many condenser lenses (single lenses) are used in the projector.
The projector lens and the integrator can be regarded as a group of the single
lenses.
Names of the condenser lenses and the relay lenses are attached with the
functional names for easy distinction.
Their basic roles are the collection and the bending of beams.

[LCD panel]: [color][projection][polarization]
This is a device to display a video image.
The role of the projector is the enlargement of this image and the projection of the
image at a screen. The panel is the core item for the projector.
Since the LCD panel is used to display images through the rotation of the
polarized beams, the polarization plates are always installed on the incident and
outgoing sides of the light.
An MLA is installed to increase the brightness (= transmission factor = opening
factor). A dust-proofing glass is attached so that dust and contaminants can be
made less visible on the display block. Many functions are secured in such a
manner.

[Polarization plate]: [projection][ polarization]
This is a component intended to enter the polarized beam in the LCD panel.
Unlike the polarizer, this item comes in a thin film stuck to an ordinary glass
substrate, referred to as the polarization plate.
The analyzer (plate) is a polarizer allocated on the outgoing side of the LCD
panel. It is called the analyzer for distinction.
Recently, the polarization plates have tended to be the adhesion of the
wavelength plates, compared to the polarized wave attribute of the XDP.

17-27

[Polarizer and Analyzer [polarization plate and analyzer plate]]
Basically, the polarizer and the analyzer are the same polarization films.
The LCD panel is made possible to display images when it is installed in the state that
it is sandwiched by the two polarization films.
The polarizer has a (control) function of aligning the polarized waves to be entered in
the LCD panel. The analyzer has a function of the absorption and interruption of the
light twisted and generated from the panel. Its (detecting) function is to establish
images of white, gray, and black. Because of this function, NEC calls the incident side
polarization film the polarizer and the outgoing side polarization film the analyzer.
Generally speaking, the polarizer and the analyzer are installed in such a posture that
they cross at right angles with the transmission axis where the polarized waves pass
through.

[Configuration of the polarization plate]
The polarization plate configuration used in the projector comes in a variety of types.
It depends on the type of glass substrate, polarizer, presence of a phase differential plate, and the
recent use of the double polarization plate or the polarization plate where the films are piled in
stacks to be referred to as the Wide View (WV). Each has an attractive function to improve
performance. On the contrary, there are reports of cases when a problem of “color unevenness” is
caused as a result of expansion and contraction of films in the layer configuration.

differential plate is about 0.1mm.)
The polarization plate has a function that only the specific polarization can pass
through. The phase differential plate has a function that a specific polarization
such as the P wave is rotated and turned into the S wave.

[Sapphire glass and white-plate glass]
Along with the recent improvement of brightness for the projector, a great problem
has arisen in regard to the method of cooling because the heat load has been
increased in the polarization plate and the analyzer plate.
To solve this problem, sapphire glass has tended to be used as a glass plate where
polarizers and analyzers are stuck. Compared with the white plate, the BK7, etc.
used generally, the heat dissipation property of the glass or the heat conductivity is
extremely high and it is possible to increase the effect of cooling.
However, this material is very expensive because it is a specific type of glass. It is
the same item as the [sapphire glass or the glass that is hard to be hurt] used in
watches. In addition, it is manufactured (processed) by an expensive method.

[XDP]: [color][projection][polarization][direction]
The KDP is an acronym of the Cross Dichroic Prism.
When it is seen from above, it looks like a character X. The name comes from this fact.
Four triangular prisms are used to make this item. By evaporation, the R and B prisms
are coated with the dichroic films of reflection and the G prisms are coated with those
of transmission. Since then, they are stuck together.
According to the model, the incident and outgoing planes are processed for AR
coating or stuck with analyzers.

17-32

[Projection lens]: [illumination] [projection]
This item is intended to project a video image that is displayed on the LCD panel.
Usually, it is composed of ten-odd single lenses.The lenses to be used are made
of expensive glass materials or processed with high accuracy.
In many projectors, zoom type lenses are used. Therefore, the zoom rings and the
focus rings are provided.

Relay optical path
The current majority of the LCD projectors is an optical system where the XDP
is used. In many cases, the XDP-applied system uses a relay optical path in its
illumination system.
The relay optical path is an optical path where the parts for relaying the light
are provided. In the case of this projector, the relay optical path has a role of
radiating the light on the LCD to any other LCD located in a place where the
optical path length is different.
At present, “B” or “R” may be used as a relay optical path.

17-35

Relay optical path: Relaying of the light
The distribution of brightness (distribution of illumination) can change with the
distance from the lamp.
The relay optical path is called so because it is used to relay the light to a distant
place without changing the intensity of the illuminance distribution.
Since optical relaying is carried out by the use of lenses, the illuminance distribution
appears in an equivalent size. However, it is a reverse distribution, both vertically
and horizontally.

→This vertically and horizontally reversed illuminance distribution can be a
cause of color unevenness.

Chiral
Chiral is considered to have arisen from the word source of chiral smectic LC,
etc. It is used to indicate the direction of LC twist. (Unclear if it is general or not)
Chiral R and Chiral L are often used to mean that the LC molecules are twisted
and sealed in the panel. According to the twisting direction (clockwise or
counterclockwise), we use “R/L chiral” for distinction.

Rubbing
The TN (Twisted Nematic) type liquid crystal is arranged in a specific direction
according to the type of orientation membrane. To establish this orientation, the
rubbing method or the like is often used.
The frequently used word of 45° rubbing (orientation) or 90° rubbing
(orientation) indicates the rubbing direction (angle).
Example: Epson uses the naming of 90° rubbing and SONY uses 45° rubbing.

17-37

MPCD
The MPCD is an acronym of the Minimum Perceptible Color Difference.
According to simplified explanations, the MPCD is a value that is 2000
times of the distance from the locus of black body radiation on the
coordinates of the RUCS color system of Judd.
Accordingly, when color on the black body radiation is defined as white,
it indicates how much it is distant from white.
If the MPCD code is “+”, this indicates that it is shifted from white in the
direction of green. If it is “-“, it is shifted from white in the direction of
magenta.
