1. A display device, comprising:
a plurality of light emitting pixels that emit light;
a plurality of 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,
wherein 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,
the first sensing pixels and the second photosensors are alternately disposed in a first column, and the second sensing pixels and the first photosensors are alternately disposed in a second column, 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.
