Before adjusting White-balance , the AV ADC
should be done
7. White Balance
*Test Equipment
8 Color Analyzer (CA-210/CH.9)
=> When you adjust LCD color temperature, on Color
analyzer (CA-210), you should use Channel 9 which
is Matrix compensated (White, Red, Green, Blue
revised) by CS-1000 and adjust in accordance with
White balance adjustment coordinate which is
specified on the next..

1 Adjust in the place where the influx of light like floodlight
around is blocked. (illumination is less than 10ux).
2.1 In case of PDP: Measure and adjust after sticking the Color
Analyzer (CA-100+, CA-210) to the side of the module.
2.2 In case of LCD: Adhere closely the Color Analyzer (CA-210)
to the module less than 10cm distance, keep it with the
surface of the Module and Color Analyzer's Prove
vertically.(80~100°).
2.3 Aging time
- After aging start, keep the power on (no suspension of
power supply) and heat-run over 15 minutes.
- In case of PDP, keep white pattern using inside pattern.
- In case of LCD, using 'no signal' or 'full white pattern' or the
others, check the back light on
