Abstract
A display device includes a display panel, a gate driver, and a driving controller. The display panel includes a pixel. The gate driver applies an anode initialization signal to the pixel. The driving controller receives a horizontal synchronization signal, receives input image data at a variable frame frequency, and controls the gate driver. A frame period for the display panel includes a scan period and one or more hold periods, the driving controller generates a count value by counting a number of pulses of the horizontal synchronization signal, and determines a current frame period as the hold period when the count value exceeds a reference value, and a time length of the anode initialization signal in each of the one or more hold periods is longer than a time length of the anode initialization signal in the scan period.
