Abstract
In a display system, a display device includes multiple common electrodes used for both image display and touch detection. Within a frame period of the display device, a display period for which the display device displays an image and a touch detection period for which a touch detection circuit performs touch detection are alternately arranged. The display device includes a first touch detection region and multiple second touch detection regions, configured by dividing multiple common electrodes into multiple groups. During multiple touch detection periods, the touch detection circuit performs touch detection in the same first touch detection region and in a second touch detection region different for each touch detection period.
