4.2. White Balance Adjustment
4.2.1. Overview
▪ W/B adj. Objective & How-it-works
(1) Objective: To reduce each Panel's W/B deviation
(2) How-it-works : 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 condition : normal temperature
1) Surrounding Temperature : 25 °C ± 5 °C
2) Warm-up time: About 5 Min
3) Surrounding Humidity : 20 % ~ 80 %
4.2.2. Equipment
(1) Color Analyzer: CA-210 (OLED Module : CH 17)
(2) Adjustment Computer(During auto adj., RS-232C protocol
is needed)
(3) Adjustment Remote control
(4) Video Signal Generator MSPG-925F 720p/216-Gray
(Model: 217, Pattern: 78)
→ Only when internal pattern is not available
▪ Color Analyzer Matrix should be calibrated using CS-100.

2) Zero calibrate probe then place it on the center of the
Display.
3) Connect Cable.(RS-232C to USB)
4) Select mode in adj. Program and begin adj.
5) When adj. is complete (OK Sign), check adj. status pre
mode. (Warm, Medium, Cool)
6) Remove probe and RS-232C cable to complete adj.
▪ W/B Adj. must begin as start command “wb 00 00” , and
finish as end command “wb 00 ff”, and Adj. offset if need.
(2) Manual adjustment. method
1) Set TV in Adj. mode using POWER ONLY key.
2) Zero Calibrate the probe of Color Analyzer, then place it
on the center of LCD module within 10 cm of the
surface.
3) Press ADJ key → EZ adjust using adj. R/C → 9. White-
Balance then press the cursor to the right(key ►). When
right 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 204 Gray pattern.
▪ Adj. condition and cautionary items
1) Lighting condition in surrounding area
Surrounding lighting should be lower 10 lux. Try to
isolate adj. area into dark surrounding.
2) Probe location: Color Analyzer (CA-210) probe should
be within 10 cm and perpendicular of the module
surface (80°~ 100°)
3) Aging time
- After Aging Start, Keep the Power ON status during 5
Minutes.
- In case of OLED, Back-light on should be checked
using no signal or Full-white pattern.
4.2.6. Reference (White balance Adj. coordinate and
color temperature)
▪ Luminance : 206 Gray
▪ Standard color coordinate and temperature using CS-1000
(over 26 inch)
