Abstract: A touch sensor includes sensor pixels which provide output currents which change in response to a touch made by a user, a sensor scan driver coupled to the sensor pixels through sensor scan lines and supplies sensor scan signals to the sensor pixels, and a read-out circuit coupled to the sensor pixels through output lines, and senses a touch using the output currents. The sensor scan driver changes a scheme for supplying the sensor scan signals depending on a fingerprint sensing mode and a touch sensing mode.

Abstract: A display device includes a display panel including a display layer having light-emitting elements on the substrate, and a sensor electrode layer on the display layer. The sensor electrode layer includes sensor electrodes in a sensor area, sensor lines electrically connected to the sensor electrodes and a first conductive pattern spaced apart from the sensor lines and sensor electrodes. The sensor lines and the first conductive pattern are in a sensor peripheral area adjacent to the sensor area. The first conductive pattern is an antenna.
