5.1.5.2. 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) Adjustment mode : mode – Medium
(3) Warm
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 W gain to 192 (default
data) and decrease the others.
3) Adjustment mode : mode – Warm
(4) THX(Warm)
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 W gain to 192 (default
data) and decrease the others.
3) Adjustment mode : mode – Warm
4) Auto White balance 4 point
5) Adjust 100 IRE White Balance
6) Adjust Gamam 2.2 each IRE (60, 40, 20). Using max
luminance
7) Complete 4 point gamma, W/B.
