▪ If internal pattern is not available, use RF input. In EZ
Adj. menu 6.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 206 Gray pattern.
* CASE Cool
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.
How to adjust
1. If G gain is adjusted over 172 and R gain and B
gain less than 192 , Adjust is O.K.
2. If G gain is less than 172 , increase G gain by up to
172, and then increase R gain and B gain same
amount of increasing G gain.
3. If R gain or B gain is over 255 , Readjust G gain
less than 172, Conform to R gain is 255 or B gain is
255
* 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) 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
▪ 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°)
5.2.6. Reference (White balance Adj. coordinate and
color temperature)
▪ Luminance : 204 Gray
▪ Standard color coordinate and temperature using CS-1000
(over 26 inch)
▪ Standard color coordinate and temperature using CA-210(CH 14)
5.2.7. LED White balance table
- EDGE LED module change color coordinate because of
aging time.
- Apply under the color coordinate table, for compensated
aging time.
