5.1.5.2. OLED White balance table
(1) Cool Mode
- Purpose : Especially B-gain fix adjust leads to the
luminance enhancement. Adjust the color temperature to
reduce the deviation of the module color temperature.
- 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 ).
- Adjustment mode : mode – Cool
(2) Medium / Warm Mode
- Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature
- Principle : To adjust the white balance without the
saturation, Fix the B gain to 192 (default data) and
decrease the others
- Adjustment mode : mode – Medium
(3) Warm
- Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature.
- Principle : To adjust the white balance without the
saturation, Fix the W gain to 192 (default data) and
decrease the others.
- Adjustment mode : mode – Warm
(4) THX(Warm)
- Purpose : Adjust the color temperature to reduce the
deviation of the module color temperature.
- Principle : To adjust the white balance without the
saturation, Fix the W gain to 192 (default data) and
decrease the others.
- Adjustment mode : mode – Warm
- Auto White balance 4 point
- Adjust 100 IRE White Balance
- Adjust Gamam 2.2 each IRE (60, 40, 20). Using max
luminance
- Complete 4 point gamma, W/B.
