5.4. Adj. Command (Protocol)
(1) RS-232C Command used during auto-adj.
(2) Adjustment Map
5.5. Adjustment method
5.5.1. 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 adjustment.
(5) When WB adjustment is completed with OK message, check
adjustment status 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.
5.5.2. White balance table
(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
(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
5.6. Reference(White Balance Adj. coordinate
and color temperature)
(1) Luminance: 204 Gray, 80IRE
(2) Standard color coordinate and temperature using CS-1000
(over 26 inch)
(3) Standard color coordinate and temperature using CA-210
(CH-17)
6. Tool Option setting & Inspection
▪ Press "ADJ" key on the Adjustment remote control, then
select Tool option.
7. Magic motion remote control check
Results are automatically marked in Instart OSD after through
the AP/Magic Remocon Equipment on the line.
