Abstract
A method for driving a display panel displays a video image signal that includes a plurality of images having different frame periods. The method includes setting a frame period including one or more light emission periods, and one or more light extinction periods. The method also includes dividing at least one frame period into a plurality of light emission periods and a plurality of light extinction periods, and adjusting lengths of the plurality of light emission periods and lengths of the plurality of light extinction periods based on a ratio between a maximum frequency of the frame period and a currently set frequency of the frame period. The method further includes displaying the video image signal by causing light emitting elements of the display panel to emit light during the adjusted light emission periods, and to extinguish light during the adjusted light extinction periods.
