Zusammenfassung:A display device including a display panel including pixels that emit light on a frame basis. An input sensing unit includes driving electrodes and sensing electrodes. A driving signal generator is configured to provide driving signals to the driving electrodes. Analog front-ends are configured to receive sensing signals depending on the driving signals from the sensing electrodes. A signal processor is configured to detect touch input, based on differential output values of the analog front-ends. The driving signal generator provides the driving signals to the driving electrodes while avoiding a period in which a pulse of a vertical synchronization signal defining start of the frame is generated.
