(2) Manual adjustment. method
1) Set TV in Adj. mode using POWER ON key.
2) Zero Calibrate the probe of Color Analyzer, then place it
on the center of LCD module within 10 cm of the surface.
3) Press ADJ key → EZ adjust using adj. R/C → 7. White-
Balance then press the cursor to the right(key ►).
(When right key(►) is pressed 216 Gray internal pattern
will be displayed)
4) 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.
5) Adjustment is performed in COOL, MEDIUM, WARM 3
modes of color temperature.
▪ If internal pattern is not available, use RF input. In EZ Adj.
menu 7.White Balance, you can select one of 2 Test-
pattern: ON, OFF. Default is inner(ON). By selecting OFF,
you can adjust using RF signal in 216 Gray pattern.
* CASE Cool
First adjust the coordinate far away from the target value(x, y).
1) x, y > target
2) x, y < target
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.
How to adjust
1. Fix G gain to 172
Adjust R Gain and B Gain(In Case of Mostly Blue Gain
Saturation)
2. When B Gain > 255, Release Fixed G Gain and Readjust
* CASE Medium / Warm
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) The one value is bigger than the target then the other
one should be not much more bigger than target.
iii) In case that we take x off, we also take R (G-gain fix)
In other case that we take y off, we also take G(R-gain fix)
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.
▪ Adjustment condition and cautionary items
1) Lighting condition in surrounding area
Surrounding lighting should be lower 10 lux. Try to isolate
adj. area into dark surrounding.
2) Probe location
: Color Analyzer(CA-210) probe should be within 10 cm and
perpendicular of the module surface.(80° ~ 100°)
3) Aging time
- After Aging Start, Keep the Power ON status during 5
Minutes.
- In case of LCD, Back-light on should be checked using
no signal or Full-white pattern.
4.2.6. Reference (White Balance adjusmtment
coordinate and color temperature)
▪ Luminance : 216 Gray
▪ Standard color coordinate and temperature using CS-1000
(over 26 inch)
▪ Standard color coordinate and temperature using CA-210(CH 14)
4.2.7. ALELF & EDGE LED White balance table
- EDGE LED module change color coordinate because of
aging time.
- Apply under the color coordinate table, for compensated
aging time.
