A method for driving a display includes following steps. A display panel is divided into a plurality of bright regions and a plurality of dark regions, wherein the dark regions and the bright regions are alternately arranged so that the bright regions within the display panel are not adjacent to each other. Next, a full-color frame is divided into four sub-frames, wherein the sub-frames are matched with the four color-orders one by one. In this way, the display randomly displays the sub-frames in a frame period.
