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.

Abstract: A display device includes: a similar gray level block detector configured to detect a pixel data block in which a gray level difference between a plurality of pixel data included in an image signal is smaller than or equal to a threshold; a skin tone detector configured to detect the pixel data block including a skin tone; and a gamma processor configured to apply a first gamma to a plurality of pixel data included in the pixel data block when the pixel data block does not include the skin tone and apply a second gamma to the plurality of pixel data included in the pixel data block when the pixel data block includes the skin tone.
