Abstract: A display device includes a display panel including a plurality of pixel rows, and a panel driver which drives the display panel. The panel driver determines whether input image data represents a still image. When the input image data represents the still image, the panel driver determines a flicker value of the still image, applies a compensation value corresponding to a carry shift interval to the flicker value, determines a driving frequency for the display panel based on the flicker value to which the compensation value is applied, and performs an alternate driving operation for the display panel at the driving frequency.
