4.1. White Balance adjustment
▪ W/B Equipment condition
CA210 : LED -> CH14, Test signal: Inner pattern(80IRE)
▪  Above 5 minutes H/run in the inner pattern. (“power on” key 
of adjust remote control) 
▪  If it is executed W/B adjustment in 2~3 minutes H/run, it is 
adjusted by Target data.
  (For OS LED / Direct LED module)
▪ Normal line
*  Aging chamber
* 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

3) x >target, y < target
4) x < target, y > target
   -  Every 4 case have to fit y value by adjusting B Gain 
and then fit x value by adjusting R-Gain.
   -  In  this  case,  increasing/decreasing  of  B  Gain  and  R 
Gain can be adjusted.
