Abstract: A display device includes light emitting pixels that emit light, photosensors each controlling a sensed current according to an incident light, and a read-out circuit that senses the sensed current of each of the photosensors and converts the sensed current into digital sensed data. In a sensing mode including a first frame period and a second frame period, the light emitting pixels include first sensing pixels that emit the light during the first frame period and second sensing pixels that do not emit the light during the first frame period, the photosensors include first photosensors and second photosensors, and a first distance between any one of the first sensing pixels and a first photosensor adjacent to the first sensing pixel among the first photosensors is greater than a second distance between the first sensing pixel and a second photosensor adjacent to the first sensing pixel among the second photosensors.

Abstract: A display device includes: a substrate; a plurality of light emitting parts on the substrate, and to emit light; a plurality of light sensing parts on the substrate, and to sense incident light; a bank layer partitioning the plurality of light emitting parts and the plurality of light sensing parts; and a touch sensing layer including a touch electrode on the bank layer. A first distance between one light sensing part from among the plurality of light sensing parts and the touch electrode in one direction is smaller than a second distance between a first light emitting part of the plurality of light emitting parts and the touch electrode in the one direction.
