4.3. White Balance Adjustment
4.3.1 Overview
(1) W/B adj. Objective & How-it-works
(2) Objective: To reduce each Panel’s W/B deviation
(3) 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.
(4) Adj. condition : normal temperature
1) Surrounding Temperature : 25 ºC ± 5 ºC
2) Warm-up time: About 5 Min
3) Surrounding Humidity : 20 % ~ 80 %
4.3.2 Equipment
1) Color Analyzer: CA-210 (LED Module : CH 14)
2) Adj. Computer(During auto adj., RS-232C protocol is
needed)
3) Adjust Remote control
4) Video Signal Generator MSPG-925F 720p/216-Gray
(Model:217, Pattern:78)
-> Only when internal pattern is not available
A Color Analyzer Matrix should be calibrated using CS-1000
