Abstract
A system for operating a color flat panel display (FPD) is provided that includes a color FPD, a light source, and a display processing device. The color FPD has an adjustable color depth and is configured to reflect ambient light. The light source transmits light through the bottom surface of the color FPD. The display processing device is coupled to the color FPD and decreases the color depth of the color FPD when the light source is activated and increases the color depth of the color FPD when the light source is turned off.
