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) Surrounding Humidity : 20 % ~ 80 %
4.2.2. Equipment
(1) Color Analyzer: CA-210 (LED Module : CH 14)
(2) Adjustment Computer(During auto adj., RS-232C protocol
is needed)
(3) Adjustment Remote control
(4) Video Signal Generator MSPG-925F 720p/204-Gray
(Model: 217, Pattern: 49)
→ Only when internal pattern is not available
▪ Color Analyzer Matrix should be calibrated using CS-100.
4.2.3. Equipment connection MAP
4.2.4. Adj. Command (Protocol)
<Command Format>
- LEN: Number of Data Byte to be sent
- CMD: Command
- VAL: FOS Data value
- CS: Checksum of sent data
- A: Acknowledge
Ex) [Send: JA_00_DD] / [Ack: A_00_okDDX]
▪ RS-232C Command used during auto-adjustment.
Ex) wb 00 00 -> Begin white balance auto-adj.
wb 00 10 -> Gain adj.
ja 00 ff -> Adj. data
jb 00 c0

...
wb 00 1f → Gain adj. completed
*(wb 00 20(Start), wb 00 2f(end)) → Off-set adj.

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 ON.
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 → 7. White-
Balance then press the cursor to the right(key ►).
(When right key(►) is pressed 204 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) Adjustment is performed in COOL, MEDIUM, WARM 3
modes of color temperature.
▪ 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 204 Gray pattern.
▪ Adjustment 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
