PANEL ADJUSTMENT TO BE PERFORMED BY

QUALIFIED BARCO PERSONNEL ONLY

The adjustment procedure must be performed with great care. Panel settings
have a dramatic influence on the light output, contrast ratio and color tracking
of the projector.

Reasons for Adjustment

Recommendation

Set Up

Projector settings

Have the adjustment procedure performed after the following occurrences;

1) Replacement of an LCD Panel.

2) Replacement of the LCD Driver Module.

- Before starting any adjustment procedure, first, clean the not replaced panels and
analyzers (see the respective cleaning kit: Art. No R5976057)

- In case of a Software update (see procedure Info T 331), execute first the update
before starting the panel, uniformity and TCR adjustments.

1) The projector must be set up in a table mounted configuration.

2) The room where the procedure is to be performed must be darkened.

Before starting any adjustment procedure, first, set for the projector the Baudrate on
9600 and the address on 001, as follows,

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.

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 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

Line-up of the
measurement apparatus

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.
