ABSTRACT:
An overdrive system for driving a display device. A host machine includes a display interface for connecting with the display device. The display interface includes a display chip and a video memory. The overdrive system includes a frame buffer for holding the display data of the previous frame. The frame buffer uses a portion of the video memory space. The overdrive system also includes an overdrive look-up table coupled to the display chip to provide a correspondence between the overdrive display data, the display data of the previous frame and the display data of the present frame. The display chip retrieves overdrive display data from the overdrive look-up table according to the display data of the previous frame obtained from the frame buffer and the display data of the present frame and transmits the overdrive display data to the display device so that an image is formed on the display panel.
