Abstract
A display device includes a display panel, an input sensor disposed on the display panel and sensing an input during a sensing frame period, a display controller receiving a vertical synchronization signal and a horizontal synchronization signal and controlling driving of the display panel in response to the vertical synchronization signal and the horizontal synchronization signal, and a sensor controller providing a transmission signal including a plurality of sampling periods to the input sensor. The display controller provides frequency information of a display frame period to the sensor controller using at least one of the vertical synchronization signal and the horizontal synchronization signal, and the sensor controller controls the number of the sampling periods of the sensing frame period based on the frequency information.
