Abstract
A system for operating a color flat panel display (FPD) is provided that includes a color FPD, a rear 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 EL light source is activated and increases the color depth of the color FPD when the EL light source is turned off. The color flat panel display is configured to allow more reflection of ambient light than transmission of light emitted from the light source.
