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 signal receiver, a signal generator, and a signal corrector. The signal receiver receives an image signal. The signal generator generates a data signal for each of a first color pixel and a second color pixel based on the image signal. The signal corrector generates corrected data for the first color pixel based on the data signal for the second color pixel in a single driving mode. The first color pixel and the second color pixel emit light of different grayscale values of a same color. The first color pixel is driven and the second color pixel is not driven in the single driving mode.
