4. Total Assembly line process
4.1. Adjustment Preparation
· W/B Equipment condition
CA210 : CH 14(LED), Test signal : Inner pattern (85IRE)
· Above 5 minutes H/run in the inner pattern. (“power on” key
of adjust remote control)
* 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 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.

In the SET applied LED module, as to physical characteristics
of LED Module, the sets takes a 120 minutes by aging time to
stabilize a color coordinates. So White Balance Control
equipments get the SET Aging Time from SET and then going
to control the W/B by revise color coordinates in the each time
Cautions) The Time Table of color coordinates by SET Aging Time
** 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)
* Manual W/B process using adjusts Remote control.
Dynamic contrast : off
Dynamic color : off
OPC : off
Energy saving mode : off
• After enter Service Mode by pushing “ADJ” key,
• Enter White Balance by pushing “
G” key at “3. White
Balance”.
