4.2.7. EDGE & IOL LED White balance table
▪ Edge & ALEF LED module change color coordinate because
of aging time.
▪ Apply under the color coordinate table, for compensated
aging time.

4.2.8. OLED White balance table
(1) Cool Mode
1) Purpose : Especially B-gain fix adjust leads to the
luminance enhancement. Adjust the color temperature
to reduce the deviation of the module color temperature.
2) Principle : To adjust the white balance without the
saturation, Adjust the B gain more than 192 (If R gain or
G gain is more than 255, G gain can adjust less than
192) and change the others (R/G Gain).
3) Adjustment mode : mode - Cool
(2) Medium
1) Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature.
2) Principle : To adjust the white balance without the
saturation, Fix the B gain to 192 (default data) and
decrease the others.

(3) Warm
1) Purpose : Adjust the color temperature to reduce the

2) Principle : To adjust the white balance without the
saturation, Fix the W gain to 192 (default data) and
decrease the others.
