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. The display drivers drives a display panel at a second frequency lower than the first frequency in a first mode, provides scan signals to pixels during a display period of a display frame period, and stops providing the scan signals during a display waiting period of the display frame period. When the display driver switches from the first mode to a second mode, the display driver drives the display at a third frequency lower than the second frequency, and the touch driver increases the touch waiting period of the touch frame period.
