5. Total Assembly line process
5.1. Adjustment Preparation
▪ W/B Equipment condition
CA210: CH14, Test signal: Inner pattern(80IRE)-LED Module
▪ Above 5 minutes H/run in the inner pattern. ("power on" key
of Adjustment remote control)
* The spec of color temperature and coordinate.
▪ W/B Table in process of aging time
- LGD / CMI Module
- AUO/ COST/ SHARP/ BOE Module which cool spec is 13000K
* Connecting picture of the measuring instrument
(On Automatic control)
Inside Pattern is used when W/B is controlled. Connect to
auto controller or push Adjustment Remote control POWER
ON → Enter the mode of White-Balance, the pattern will
come out.
* Auto-control interface and directions
(1) Adjust in the place where the influx of light like floodlight
around is blocked. (Illumination is less than 10 lux).
(2) Adhere closely the Color analyzer(CA210) to the module
less than 10 cm distance, keep it with the surface of the
Module and Color analyzer's prove vertically.(80° ~ 100°).
(3) Aging time
- After aging start, keep the power on (no suspension of
power supply) and heat-run over 5 minutes.
- Using 'no signal' or 'POWER ONLY' or the others, check
the back light on.

Color Temperature : COOL, Medium, Warm.
One of R Gain/G Gain/ B Gain should be kept on 0xC0, and
adjust other two lower than C0.(When R/G/B Gain are all
C0, it is the FULL Dynamic Range of Module)
