the mode of White-Balance, the pattern will come out.
9-3. Auto-control interface and directions
(1) Adjust in the place where the influx of light like floodlight
around is blocked.(illumination is less than 10ux)
(2) Measure and adjust after sticking the Color Analyzer(CA-
100+, CA210) to the side of the module.
(3) Aging time
- After ajing start, keep the power on(no suspension of
power supply) and heat-run over 15minutes.
- keep white pattern using inside pattern.

One of R Gain/ G Gain/ B Gain should be kept on 80, and
others are controlled lowering from 80
(1) Press ‘power on’ of the control R/C, set heat run to white
by pressing and heat run over 15 minutes.(Set: RS-232

(2) Zero Calibrate CA-100+, and stick the sensor to the center
of PDP module surface when you adjust.
(3) Double click In-start key on Controlling R/C and get in
‘white balance’.
(4) Set test-pattern on and display inside pattern. Control is
carried out on three color temperature, COOL, MEDIUM,
WARM. (Control is carried out three times.)
WARM. (Control is carried out three times.)
(5) When the R/G/B GAIN is 80 on OSD, it is the FULL
DYNAMIC Range of the Module. In order to control white
balance without the saturation of FULL DYNAMIC Range
and DATA, one of R Gain / G Gain / B Gain should be kept
on 80, and other two is controlled lowering from 80.

and DATA, one of R Gain / G Gain / B Gain should be kept
on 80, and other two is controlled lowering from 80.
* Color Temperature: Cool, Medium, Warm
(1) When R GAIN is set to 80
- Control G GAIN and B GAIN by lowering from 80.
(2) When B GAIN is set to 80
- Control R GAIN and G GAIN by lowering from 80.
(3) When G GAIN is set to 80
- Control R GAIN and B GAIN by lowering from 80.
- Control R GAIN and B GAIN by lowering from 80.
One of R Gain / G Gain / B Gain should be kept on 80, and
adjust other two lower than 80.
(When R/G/B GAIN are all 80, it is the FULL DYNAMIC
Range of Module)
adjust other two lower than 80.
(When R/G/B GAIN are all 80, it is the FULL DYNAMIC
