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 device comprises a substrate, a plurality of emission portions disposed on the substrate and emitting light, a plurality of light sensing portions disposed on the substrate and sensing an incident light, a bank layer partitioning the plurality of emission portions and the plurality of light sensing portions, and a touch sensing layer disposed on the bank layer. The touch sensing layer comprises a first touch insulating pattern disposed on the bank layer and partitioning a light opening overlapping the plurality of light sensing portions and a touch electrode disposed on the first touch insulating pattern. A cross-sectional shape of the first touch insulating pattern has a reverse tapered shape having a width that decreases towards a top surface of the substrate.

Abstract: A fingerprint sensor for a display device includes a light sensing layer including a light sensing element, and an optical layer including a light transmitter disposed in a light-transmitting area and a light blocker disposed in a light-blocking area. The light-transmitting area includes a plurality of unit light-transmitting areas separated by the light-blocking area, and each of the unit light-transmitting areas has a first width and the light-blocking area has a second width, the first width being in a range of about 5 times to about 200 times the second width.
