4.2.2.3. Adjustment
(1) Set TV in Adj. mode using POWER ON
(2) Zero Calibrate the probe of Color Analyzer, then place it on
the center of LCD module within 10cm of the surface.
(3) Press ADJ key -> EZ adjust using adj. R/C -> 6. White-
Balance then press the cursor to the right (KEY►). When
KEY(►) is pressed 216 Gray internal pattern will be
displayed.
(4) One of R Gain / G Gain / B Gain should be fixed at 192,
and the rest will be lowered to meet the desired value.
(5) Adj. is performed in COOL, MEDIUM, WARM 3 modes of
color temperature.
If internal pattern is not available, use RF input. In EZ Adj.
menu 6.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.
4.2.3. OLED White balance table
4.2.3.1. Cool Mode
(1) Purpose : To reduce each Panel’s W/B deviation
(2) Principle : When R/G/B gain in the OSD is at 192, it means
the panel is at its Full Dynamic Range. In order
to prevent saturation of Full Dynamic range and
data, one of R/G/B is fixed at 192, and the other
two is lowered to find the desired value.
(3) Adjustment mode : : normal temperature
1) Surrounding Temperature: 25 ºC ± 5 ºC
2) Warm-up time: About 5 Min
3) Surrounding Humidity: 20% ~ 80%
4) Before White balance adjustment, Keep power on status,
don’t power off

4.2.3.2. 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
4.2.4. LED White balance table
4.2.4.1. 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
4.2.4.2. 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
