5.2.3. LED White balance table
5.2.3.1.Cool Mode
(1) Purpose : Especially G-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 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 ).
(3) Adjustment mode : mode – Cool
**For 55/65LA97 Models
* R-fix adjustment
Adjust modes (Cool), Fix the R gain to 210 (default data) and
change the others (G/B Gain ).
- Adjust the R gain more than 210 ( If G gain or B gain is less
than 0 , R gain can adjust more than 210 )
and change the others ( G/B Gain ).
Adjust two modes(Medium / Warm), Fix the one of R/G/B gain
to 192 (default data) and decrease the
others.
▪ If internal pattern is not available, use RF input. In EZ Adj.
menu 7.White Balance, you can select one of
2 Test-pattern: ON, OFF. Default is inner(ON). By selecting
OFF, you can adjust using RF signal in 216
Gray pattern.
5.2.3.2. Medium / Warm Mode
(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 one of R/G/B gain to 192
(default data) and decrease the others.
(3) Adjustment mode : Two modes – Medium / Warm
5.2.4. OLED White balance table
5.2.4.1.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
5.2.4.2. Medium Mode
(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
5.2.4.3. Warm Mode
(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

▪ Change reason : When vivid mode, more detail than other
company set.
● In case of Edge LED module, the color coordinates is
changing by aging, so you have to use the below table.
