Abstract
Techniques for providing LED-based backlighting in liquid crystal flat panel displays are disclosed. In one embodiment, the backlighting includes at least three color groups of light emitting diodes (LEDs) that are turned on successively for one frame of image. Liquid crystals (pixels) in an LCD are controlled in accordance with a display signal to transmit none, all or a determined amount of one or more of the colored lights from the three color groups of light emitting diodes in a cycle, resulting in an LCD with vivid colors and minimized tailing effects.
