Abstract: A display device includes a display panel that displays an image, an input sensing layer disposed on the display panel and that senses an input applied thereto from outside of the display device, a display driver that receives an image signal and drives the display panel at a first driving frequency or a second driving frequency lower than the first driving frequency, and a sensing driver that drives the input sensing layer. The display panel displays the image in a plurality of frames, each including a first period and/or a second period. The sensing driver drives the input sensing layer in the first period of each of the frames when the display panel is driven at the first driving frequency, and drives the input sensing layer in the second period of each of the frames when the display panel is driven at the second driving frequency.

Abstract: A display apparatus is disclosed that includes a touch panel, a display panel, and a touch integrated circuit (IC) configured to determine whether a first frequency, which is a driving frequency of the display panel, matches a second frequency, which is a driving frequency of the touch panel, and change the second frequency to a third frequency that is different from the first frequency when the first frequency matches the second frequency.
