Abstract
LCD panel white balance adjustment provides a desired brightness with minimal impact on optical performance by maximizing Red, Green and Blue gains of the LCD panel for a predetermined color temperature and then adjusting brightness with backlight current. For example, Red, Green and Blue gain settings are set at substantially their maximum value to achieve a color temperature of 6500 degrees and then brightness for the LCD panel is adjusted to substantially 200 nits with the gains remaining at maximized values.
