1. A display device comprising:
a display panel which displays an image based on a display frame during a display frame period;
an input sensor disposed on the display panel to sense 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 receiving at least one of the vertical synchronization signal and the horizontal synchronization signal and providing a transmission signal comprising a plurality of sampling periods to the input sensor,
wherein the display controller provides frequency information of the 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 a number of the sampling periods of the sensing frame period based on the frequency information,
wherein the number of the sampling periods generated in a first sensing frame period corresponding to a display period of the display frame period, is greater than the number of the sampling periods generated in a second sensing frame period corresponding to a blank period of the display frame period.
