Abstract

A flat panel display includes a four-color conversion unit, a backlight control unit, a backlight module, and a pixel array. The four-color conversion unit provides a first set of four color image signals corresponding to three color image input signals based on a preliminary conversion lookup table and provides corresponding conversion scaling factors. The backlight control unit generates a backlight adjusting factor based on the conversion scaling factors. The backlight module provides a backlight output having an intensity adjusted according to the backlight adjusting factor. The four-color conversion unit further provides a second set of four color image signals corresponding to the three color image input signals based on the backlight adjusting factor. The pixel array displays an image according to the second set of four color image signals and the backlight output.
