Abstract: A display device comprises a display panel including a pixel, and a panel driver configured to receive input image data in a variable frame frequency in order to drive the display panel based on the input image data. A frame period for the display panel is divided into at least one scan period and at least one or more hold periods, and a time during which the pixel performs an anode initialization operation in each of the hold periods is longer than a time during which the pixel performs the anode initialization operation in the scan period.
