4.2.8. OLED White balance
4.2.8.1. Auto WB calibration & 10% window pattern brightness
check(HDR)
(1) Set TV in ADJ mode using P-ONLY key (or POWER ON
key)
(2) Place optical probe on the center of the display
- It need to check probe condition of zero calibration before
adjustment.
(3) Connect RS-232C Cable
(4) Select mode in ADJ Program and begin a adjustment.
(5) When WB adjustment is completed with OK message,
check adjustment status of pre-set mode (Cool, Medium,
Warm, 10% window pattern brightness check)
(6) Remove probe and RS-232C cable.
▪ W/B Adj. must begin as start command "wb 00 00" , and
finish as end command "wb 00 ff", and Adj. offset if need.
4.2.8.2. 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
