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.

Abstract: A touch panel includes a first touch electrode disposed on a base substrate and a second touch electrode disposed on an insulating layer, which is disposed over the first touch electrode. The first touch electrode includes a first linear pattern disposed along a first direction and a first protrusion pattern extending from the first linear pattern. The second touch electrode includes a second linear pattern disposed along a second direction crossing the first direction and a second protrusion pattern extending from the second linear pattern. Wires connect the first touch electrode and the second touch electrode to a driving circuit. The second protrusion pattern partially overlaps the first protrusion pattern.
