4. Total Assembly line process
4.1. Adjustment Preparation
▪ W/B Equipment condition
CA210
: CCFL/EEFL -> CH9, Test signal: Inner pattern(80IRE)
  LED -> CH14, Test signal: Inner pattern(80IRE)
▪  Above 5 minutes H/run in the inner pattern. ("power on" key 
of Adjustment remote control)(Only EEFL)
▪  Edge  LED  W/B Table  in  process  of  aging  time  (Only  LGD 
Edge LED Module except AUO, CMI, IPS Module)
*  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 R/C 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.
