4.3. Adjustment of White Balance
(for Manual adjustment)
■ 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 5 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 (85% white pattern)
5) Push the ADJ key two times (entering White Balance
mode) → Enter “0413” (Password)
6) 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..
7) Adjust R/ G/ B Gain using ◄/►(VOL +/-) key on R/C.
8) Adjust three modes all (Cool / Medium / Warm) : Fix the
one of R/G/B gain and change the others
9) When adjustment is completed, 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
i) First decrease the B gain,
ii) 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
■ Standard color coordinate and temperature when using the
CA100+ or CA210 equipment (Small size inch’s color
coordinate is different from others, So use below table)
1) All Edge LED(except LGD), lamp over 26 and None
Edge LED(LGD Direct LED 42inch) and LGD Edge LED
26inch Over
2) 22” TN Edge LED
(Small size inch’s color coordinate is different from
others, so use below table)
3) 22” Lamp (CMI & THTF)
(Small size inch’s color coordinate is different from
others, So use below table)
4) W/B table in process of time which must be applied for
LGD edge LED module” (Target color coordinate is
different by aging time)
CA210 : CH 14, Test signal : Inner pattern (85IRE)
To check the Coordinates of White Balance, you have to
measure at the below conditions.
Picture Mode : Vivid(User)
Dynamic Contrast : Off , Dynamic Colour : Off
(If you miss the upper condition, the coordinates of W/B
can be lower than the spec.)
