4.4 White Balance Adjustment
4.4.1 Overview
• W/B adj. Objective & How-it-works
E F
- Objective: To reduce each Panel's W/B deviation
- How-it-works: When R/G/B gain in the OSD is at 192, it
-Adj. condition: normal temperature
1) Surrounding Temperature: 25±5°C
2) Warm-up time: About 5 Min
3) Surrounding Humidity: 20% ~ 80%
E F
4.4.2 Equipment
1) Color Analyzer : CA-210 (NCG: CH 9 / WCG: CH12 / LED:
2) Adj. Computer (During auto adj., RS-232C protocol is
needed)
3) Adjust Remocon
4) Video Signal Generator MSPG-925F 720p/216-Gray
(Model: 217, Pattern: 78)
-> Only when internal pattern is not available

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.
