摘要： A method of driving a liquid crystal display and a drive circuit for a liquid crystal display module wherein the liquid crystal display of the liquid crystal display module is controlled and the image data displayed by the liquid crystal cells is refreshed. Received frames of image data are analysed to determine if individual frames of image data have characteristics prone to showing flicker. The refresh rate is reduced if the image analysis determines that the frames received of image data do not have characteristics prone to showing flicker.
