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.
