7. White Balance Adjustment
7.1 Overview
• W/B adj. Objective & How-it-works
- Objective: To reduce each Panel’s W/B deviation
- 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.
-Adj. condition: normal temperature
1) Surrounding Temperature: 25±5ºC
2) Warm-up time: About 5 Min
3) Surrounding Humidity: 20% ~ 80%
