摘要： 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.
