Abstract: A display device includes a touch sensor, a touch driver, and display driver. The touch driver drives the touch sensor at a first frequency, provides touch driving signals to touch electrodes during a touch sensing period of a touch frame period, and stops providing the touch driving signals during a touch waiting period of the touch frame period.
