Reason For Uniformity
Correction
Color non-uniformities on a LCD projector can have two fundamentally different origins:
- the optical components and
- the LCDs.
An optical non-uniformity is present in the white as well as in the grey as in black and
can be caused by :
- poorly matched mirrors
- vignetting
- birefringence effects in the field lenses, etc
A non-uniformity caused by the LCD becomes more visible in the darker grey and
black levels. It is caused by the fact that the LCD transmission curve is not equal for
the whole LCD area. This can be a result of thickness variations or temperature
variations on the LCD which mainly cause a horizontal shift of the transmission curve.
In this case the effect will be most pronounced for the steepest part of the transmission
curve, this is the mid grey levels.
Other effects, like the stress on the glass induced by the drivers, or the variation of the
average incident angle of the light in different areas of the LCD, have a more complex
influence on the transmission curve, and therefore they are more difficult to
compensate.
With the current compensation program we can compensate the horizontal shift of
the transmission curves on different areas of the screen, so that the first order effect
of thickness and temperature variations can be compensated. As a result the
compensation will give the best results for the grey levels, but will have a very small
effect on the full (projector) white and on the black (there is some effect on e.g. the
6500K white because in that case green is already reduced).
The uniformity compensation can be modified independently on 17x13 points on the
screen. Because it is not feasible to adjust these points one by one, the program
contains an automatic adjustment in which 16 or 25 points are measured and adjusted
with the aid a color meter, and the other points are interpolated.
Program version 1.02
Preparation The Uniformity Compensation Program requires
- A PC (486, or higher) with 2 COMM ports and DOS.
- The UNI.EXE program.
- A color meter: LMT (C1210 or higher) , Thoma (TMF6 or TMF6 II) or a Minolta
CS1000 color meter.

Uniformity Correction Adjustments
- RS232 connection from the PC to the projector and to the color meter. Allow the
projector to warm up during 10 minutes. Put the lamp into the highest power mode.
Close the hoods on the projector. Put the projector in FRONT TABLE configuration.
Darken the room before the evaluation or the measurements start.
For this adjustment the projector white panel settings have to be adjusted properly.
The uniformity adjustment is completely independent from the TCR adjustment, so it
can be done before or after TCR.
Color Meter Put the color meter at the center of the image.
In case of the Thoma TMF use a diaphragm to avoid overranging of the meter. In that
case make sure that the light through the diaphragm hits the center spot on the back
of the white integration sphere.
The Minolta CS1000 is used in a reflective measurement mode. Use a perfect white
projection screen. Use the manual measurement mode with an integration time of
0.2s or more.
Check the RS232 to color meter section for the correct RS232 connections to the
color meter.

Type A to activate the Automatic Uniformity Adjustment Procedure.
WARNING : the adjustment will erase the current uniformity correction and start from
a totally uncompensated image. If necessary, the current uniformity correction can be
retrieved from the factory settings (F).
First fill in the number of points that you want to measure and press ENTER.
- 16: is quicker but less accurate
- 25: recommended : slower but more accurate.
When indicated, put the color meter in the center of the image. For the BG6300 the
reference white level will be measured, and then a selected grey level. This grey level
is adjusted to a color temperature close to 6500K.
Then put the color meter on the indicated areas on the screen. The correction values
will be changed until the target color temperature is reached. For the BG6300 also the
relative transmission compared to white will be adjusted.
On the screen you will see the measured color coordinates and transmission, the
correction values for red, green and blue, and then a measure for the speed with
which the variations in x (value kx), in y (value ky) and in the transmission (value kt)
are compensated. These values are optimized during the adjustment process.
When all points are measured, the correct interpolation between these measurement
points is calculated and sent to the projector.
The 2 following manual adjustment procedures allow to visually locate the area on the
screen where corrections can be made.
The grid agrees with the screen in FRONT TABLE configuration. The outline of the
grid agrees with the outline of the image on the screen.
The current active uniformity compensation is then read from the projector. The
compensation values for the selected grid point are displayed on the top left corner of
the display.

Manual top-bottom-left-right Adjustment Procedure: M
Type M to activate the special manual top-bottom-left-right adjustment menu.
There are 2 adjustment modes:
- CORNERS: Use the cursors to toggle between one of the 4 corners. Select a color
(with C) and press + or - to increase or decrease its contribution in that specific
corner, without changing the color temperature in the (vertical) central region of the
screen. The correction values on the selected corner are displayed.Also, see figure
below.
- BORDERS: Choose T, B, L, R to choose the top, bottom, left or right border of
the image. Select a color (with C) and press + or - to increase or decrease its
contribution to the upper, lower, left or right half of the screen. In this mode the
applied adjustment varies gradually from a maximum variation on the selected border
to 0 in the center region. The uniformity values are displayed for the two corners of
the selected border. Also, see next figure.
CORNER mode: only the value in one
corner changes, the other corners and
the central vertical line do not change.
BORDER mode: the values in two
corners change equally. The variation
decreases linearly form the selected
border to the centre.
The compensation will be maximum for the center of the box, and gradually
decrease towards the edges of the ellips or circle inscribed in the box (because
color non-uniformities tend to have a more circular than rectangular shape).

F :Restore the factory default settings on the image. Also the values on the screen
will be updated.
A :Start the automatic adjustment procedure. Instructions will be given. WARNING:
the current uniformity compensation will be erased during this process, but can be
retrieved afterwards by typing F.
M :Start the manual top-bottom-left-right adjustment procedure.
Q :Quit the program
The manual top-bottom-left-right adjustment menu.
<cursors> :Select one of the corners. The uniformity values of the selected corner
are displayed
T :Select the top border. The values of the top left and the top right corners are
displayed.
B :Select the bottom border. The values of the bottom left and the bottom right
corners are displayed.
L :Select the left border. The values of the top left and the bottom left corners are
displayed.
R :Select the right border. The values of the top right and the bottom right corners
are displayed.
C :Select the active color. Toggle between red, green, blue and white.
+ / - :Increase / decrease value of the selected corner / border and color.
<enter> :Send the current grid values to the projector.
Q :Quit the manual top-bottom-left-right adjustment menu.
Overview of Commands
The main menu:
C :Select the active color. Toggle between red, green, blue and white.
V :Enter a value for the selected point and color.
I :Initialize total grid.
+ / - :Increase / decrease value of the selected point and color.
<cursors> :Move on the grid.
<enter> :Send the current grid values to the projector.
R :Read the currently active uniformity values from the projector.
O :Open a file from the PC and show the values on the screen. The values are not
yet sent to the projector. Uniformity files have the extension *.uni, which has to be
omitted. NOTE: for the BG6300 you can load the bg6300.uni file (omit the .uni).
This file will load a average first order uniformity compensation, which is better
than no compensation at all.
S :Save the current uniformity values on the screen to a file. Again, the extension
*.uni has to be omitted.
D :Store the current active uniformity values in the projector to the factory default
settings. Use carefully, because there is no way to retrieve the old default values
after this.

2. Color tracking.
Color tracking (the color temperature is maintained over the grey scale) is realized by
measuring the transmission curve of the LCDs and by loading the correct correction
curves into the projector. As a result we will have a correct gamma curve for each
color, and hence a correct color tracking.
3. Color temperature adjustment.
In order to arrive at the right color temperatures (3200K for broadcast, 5400K for film,
6500K for video and 9300K for computer) it is necessary to do a correct balancing of
red, green and blue. From the green reduced white, lying close to the 6500K point,
still a digital fine tuning of the color balance will be necessary to exactly arrive on the
6500K point, and also on the other color temperatures 3200K, 5400K, 9300K.
Software validity
Reason for TCR The TCR Program will implement the following features:
1. Analog green reduction.
The normal white in a projector with fully driven LCD panels is too green for video
applications. To achieve a white which is more appropriate (e.g. 6500K) mainly the
maximum light output of the green panel has to be reduced. In the TCR program the
largest part of this reduction will be done on the analog LCD driver, so that only the
driving voltage interval of the green panel will be reduced without losing the number of
grey levels (8 bit grey levels are kept). In practice the driving of the green panel will be
reduced until the y color coordinate of the internal white image is close to 0.34.
Note: There is no analog green reduction necessary for the BG9300. Due to an internal
resistor network in the panels and dithering to 10 bit grey levels the number of grey
levels is already much higher than for other projectors.

Preparation
Allow the projector to warm up during 30 minutes. Put the lamp into the highest power
mode. Close the hoods on the projector. The table mount configuration is preferred.
Darken the room before the measurements start.
Adjustment procedure Preset Input Balance
The TCR Program requires
- A PC (486, Pentium 133,) with 2 COM ports and DOS.
- The TCR.EXE program and the EGAVGA.BGI file for the graphics.
- A color meter: LMT (C1210 or higher) or Thoma (TMF6 or TMF6 II). From version
1.11 and higher the TCR Program also supports a Minolta CS1000 color meter.
- A pattern generator or video generator able to show a full black and full white image
and if possible a grey image with a correct 30% and 60% signal level.
- RS232 connection from the PC to the projector and to the color meter.

Color Meter Put the color meter at the center of the image.
In case of the Thoma TMF use a diaphragm to avoid overranging of the meter. In that
case make sure that the light through the diaphragm hits the center spot on the back
of the white integration sphere.
The Minolta CS1000 is used in a reflective measurement mode. Use a perfect white
projection screen. Use the manual measurement mode with an integration time of
0.2s or more.
Check the RS232 to color meter section for the correct RS232 connections to the
color meter.
