Abstract
A display device includes a display panel, an input sensor having a plurality of first sensing electrodes and a plurality of second sensing electrodes, and a readout circuit that includes a noise filter electrically connected to the plurality of first sensing electrodes and the plurality of second sensing electrodes to remove noise of a receiving signal received from the plurality of first sensing electrodes and the plurality of second sensing electrodes. The readout circuit determines which of the first sensing electrodes are influenced by a touch based on the receiving signal as influenced electrodes, during a first sensing mode. The readout circuit adjusts a passband of the noise filter based on the number of influenced electrode and transmits a transmitting signal to the influenced electrodes, during a second sensing mode.
