5.3 White Balance Adjustment
5.3.1 Overview
▪ Case : Cool Mode
▪ Case : Cool Mode
Purpose : Adjust the color temperature to reduce the deviation of the module color
temperature.
Principle : To adjust the white balance without the saturation,
Fix the G gain to 172 (default data) and change the others ( R/B Gain ).
Adjustment mode : mode – Cool
▪ Case : Medium / Warm Mode
Purpose : Adjust the color temperature to reduce the deviation of the module color
temperature.
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.
Adjustment mode : Two modes – Medium / Warm
▪ 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.
