Abstract: A display device includes a display panel including a plurality of pixel rows, and a panel driver configured to drive the display panel. The panel driver includes a scan on time decider configured to receive line image data for each of the plurality of pixel rows, and to determine a scan on time change amount for each of the plurality of pixel rows based on the line image data, and a scan control block configured to adjust a scan pulse applied to each of the plurality of pixel rows according to the scan on time change amount.
