Abstract: A display device includes a display panel, a sensor unit overlapping the display panel and including a plurality of touch driving electrodes, a plurality of touch sensing electrodes, and a plurality of noise sensing electrodes, and a touch driving circuit supplying a driving signal to the plurality of touch driving electrodes and receiving a touch sensing signal from the plurality of touch sensing electrodes. The touch driving circuit is configured to receive a noise level signal indicating a noise level of the display panel from a host that generates image data, select at least some noise sensing channels among a plurality of noise sensing channels connected to the plurality of noise sensing electrodes, based on the noise level signal, receive a noise signal using at least some of the selected noise sensing channels, and compensate for the touch sensing signal using the received noise signal.

Abstract: A display device may include a display element layer, a sensing element layer, and a second-type sensor electrode. The display element layer may include a first through hole, a non-pixel area, and a display area. The display area may including pixels and may surround the non-pixel area. The non-pixel area may surround the first through hole. The sensing element layer may include a second through hole and a first sensing area. The first sensing area may include first-type sensor electrodes, may overlap the display area, and may surround the second through hole. The second through hole may correspond to the first through-hole. The second-type sensor electrode may overlap the non-pixel area and may be electrically insulated from the first-type sensor electrodes.
