摘要： A display device includes: a display panel; an input sensor on the display panel; a panel driving circuit to drive the display panel, and to output a synchronization signal; and a sensor controller to control the input sensor. The sensor controller determines a sensing mode in response to the synchronization signal, and changes the sensing mode to a second sensing mode when the synchronization signal is activated in a first sensing mode.
