Abstract
A display device includes a display panel including a plurality of pixels and a panel driver that drives the display panel in a first mode where an operating frequency is fixed, and a second mode where the operating frequency is variable. Each of the plurality of pixels includes a light-emitting element and a pixel driving circuit connected to a first electrode of the light-emitting element. The panel driver includes a driving controller that determines whether the operating frequency corresponds to one of predetermined compensation frequencies in the second mode, and outputs a voltage control signal depending on the determination result, and a voltage generator that changes a voltage level of an anode initialization voltage applied to the first electrode in response to the voltage control signal.
