摘要： A frame thinning out system has been used as a driving method for display device for making a gradational display with several brightness levels on the screen of a liquid crystal display device (2) and the like. This is a driving method for display device making a gradational display by setting a plurality of frame time periods, during which each of pixels on the screen of the display device (2) is controlled for displaying an image, as one integration time period, and turning on pixels only for a number of specified frame time periods corresponding to a brightness level to be displayed out of all frame time periods within the integration time period. In this driving method all pixels of the display device (2) are grouped into multiple groups each of which is composed of a plurality of pixels (A, B, C, D) contiguous to each other, the number of pixels to be turned on in each frame time period within one integration time period is selected corresponding to the specified gradation data within the same group, and the frame time period during which the number of pixels turned on is kept constant is set to a period so short that a human being does not feel flicker. In this way, viewing a plurality of pixels all over one group as a unit image area, a gradational display without noticeable flicker can be obtained.
