4. Total Assembly line process
4.1. Adjustment Preparation
· W/B Equipment condition
CA210 : CH 9, Test signal : Inner pattern (85IRE)
· Above 5 minutes H/run in the inner pattern. (“power on” key
of adjust remote control)
· In casw of Edge LED module, the color coordinates is
changing by aing, so you have to use the below table.
4.1.1. 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
4.1.2. 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) Adhere closely the Color Analyzer (CA210) to the module
less than 10cm 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 15minutes.
- Using ‘no signal’ or ‘full white pattern’ or the others, check
the back light on.
4.1.3. Auto adjustment Map (RS-232C)
**Caution **
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)
4.2. Manual W/B process using adj. R/C
• After enter Service Mode by pushing “ADJ” key,
• Enter White Balance by pushing “
G
* After done all adjustments, Press “In-start” button and compare
Tool option and Area option
value with its BOM, if it is correctly same then unplug the AC
cable.
If it is not same, then correct it same with BOM and unplug AC
cable.
For correct it to the model’s module from factory JIG model.
* Push  The  “IN STOP KEY” after completing the function
