4. Total Assembly line process
4.1. Adjustment Preparation
■ W/B Equipment condition
▪ Color analyzer(CA100+, CA210) should be used in the
calibrated ch by CS-1000
▪ Operate the zero-calibration of the CA100+ or CA-210, then
stick sensor to the module when adjusting.
▪ For manual adjustment, it is also possible by the following
sequence.
(1) Select white pattern of heat-run by pressing “POWER ON”
key on remote control for adjustment then operate heat run
longer than 15 minutes.
( If not executed this step, the condition for W/B may be
different.)
(2) Push “Exit” key.
(3) Change to the AV mode by remote control.
(4) Input external pattern (80% white pattern)
(5) Push the ADJ key => Enter “0000” (Password)
(6) Select “3. W/B ADJUST”
(7) Enter the W/B ADJUST Mode
(8) Stick the sensor to the center of the screen and select each
items (Red/Green/Blue Gain and Offset) using ▲/▼(CH +/-)
key on R/C..
(9) Adjust R/ G/ B Gain using ◄/►(VOL +/-) key on R/C.
(10) Adjust three modes all (Cool / Medium / Warm) : Fix the
one of R/G/B gain and change the others
(11) If Model is UD ,
Adjust modes (Cool) Fix the G gain to 172 (default data)
and change the others ( R/B Gain ).
Adjust two modes ( Medium / Warm) Fix the one of R/G/B
gain to 192 (default data) and decrease the others.
(12) When adjustment is completed, Enter “COPY ALL”
(13) Exit adjustment mode using EXIT key on R/C.
※
CASE
First adjust the coordinate far away from the target value(x, y).
(1) x, y >target
i) Decrease the R, G.
(2) x, y< target
ii) First decrease the B gain,
iii) Decrease the one of the others.
(3) x >target , y<target
i) First decrease B, so make y a little more than the target.
ii) Adjust x value by decreasing the R
(4). x<target , y>target
i) First decrease B, so make x a little more than the target.
ii) Adjust x value by decreasing the G

■ In the SET applied LED module (LM9600), cause of the physical
characteristics of LED Module, sets are taken a 120 minutes by
aging time to stabilize a color coordinates.
So White Balance Control equipments have to get the SET Aging
Time from the SET and then going to control the W/B by revise
color coordinates at each time
- To check the Coordinates of White Balance, you have to measure
at the below conditions.
Picture Mode : select Vivid and change
Dynamic Contrast : Off ,
Dynamic Colour : Off,
Clear White : Off
=> Picture Mode change : Vidid => Vivid(User)
(If you miss the upper condition, the coordinates of W/B can be
lower than the spec.)
※
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 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 5 minutes.
- Using ‘no signal’ or ‘full white pattern’ or the others, check
the back light on.
