US 2010/0141871 A1 · LIQUID CRYSTAL DISPLAY

Abstract

A liquid crystal display is disclosed. The liquid crystal display includes a first backlight source, a second backlight source and a liquid crystal panel. The first backlight source provides magenta backlight and the second backlight source provides green backlight. The first and second backlight sources are alternatively driven periodically to provide backlight for illustrating images. The liquid crystal panel comprises a liquid crystal layer and a color filter. The liquid crystal molecules of the liquid crystal layer are controlled for adjusting the transmittance of the backlight provided by the first and second backlight sources. The color filter includes red pixel areas, transparent pixel areas and blue pixel areas for performing color filtering operations on the backlight penetrating through the liquid crystal layer.
