A frame thinning out system has been used as a display driving method for making a gradational display with several brightness levels on the screen of a liquid crystal display device and the like. A display driving method of the present invention, sets a plurality of frame time periods, during which each of pixels on the screen is controlled to display an image, as one integration time period. Pixels are turned on only for a number of specified frame time periods corresponding to the desired brightness level. In this driving method the pixels of the display device are grouped into groups of a plurality of pixels contiguous to each other, the number of pixels to be turned on in each frame time period is selected corresponding to specified gradation data within the same group, so that the number of pixels to be turned on for one frame time period may be equal between subgroups in the scanning lines within the same group, and the frame time period is set to a period so short that a human does not feel flicker. In this way, a group of pixels as a unit image area, a gradational display without noticeable flicker can be obtained. Since no delicate shades of brightness occur among pixels to the same gradation level, the quality of the display is improved.
