A reset method and apparatus for a color liquid crystal display device that is capable of reducing a reset interval of a panel to increase a lighting time of a back light. In the method and apparatus, a reset voltage is simultaneously applied to all liquid crystal cells of the liquid crystal display device to reset the liquid crystal display device. Accordingly, all the liquid crystal cells are simultaneously reset by utilizing a common voltage or a gate voltage, so that the reset interval can not only be dramatically shortened to reduce flicker, but also color interference among red, green and blue colors can be eliminated to prevent color blur.

Reset method and apparatus for liquid crystal display

A method of driving a liquid crystal display panel that is adaptive for providing the entire panel with a brightness uniformity. In the method, the scanning direction of the panel is inverted at a desired period, for example, every frame, or within a frame. Accordingly, the average turn-on interval of all of the pixels within the panel becomes equal, so that the brightness of the entire panel can be uniform.
