5.1.5. Adjustment method
5.1.5.1. Auto WB calibration
(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)
(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
5.1.5.2. LED White balance table
(1) Cool Mode
- Purpose : Especially G-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 G gain more than 172 ( If R gain or G
gain is more than 255 , G gain can adjust less than 172 )
and change the others ( R/B 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 one of R/G/B gain to 192 (default data)
and decrease the others.
- Adjustment mode : Two modes – Medium / Warm
