A display device includes a display panel partitioned into pixel rows, and the display panel includes pixels and fingerprint sensors arranged on the pixel rows, a panel driver for driving the pixels, and a sensor driver for detecting a user fingerprint, based on a sensing signal from the fingerprint sensors. The fingerprint sensors may include first fingerprint sensors on an odd-numbered pixel row and second fingerprint sensors on an even-numbered pixel row, and an area of an anode electrode of a light receiving element in each of the first fingerprint sensors may be equal to an area of an anode electrode of a light receiving element included in each of the second fingerprint sensors.

Display device

A display device includes: a substrate; a bank layer on the substrate, and defining a light-emitting area; an organic light-emitting layer in the light-emitting area; a thin-film sealing layer covering the organic light-emitting layer and the bank layer; an inorganic layer including a base part on the thin-film sealing layer, and a protruding pattern part protruding from the base part in a thickness direction and including a lateral surface having a reverse taper angle; a first low refractive organic layer on the base part of the inorganic layer; and a high refractive organic layer covering the first low refractive organic layer and the inorganic layer. A lateral surface of the first low refractive organic layer contacts the lateral surface of the protruding pattern part, and an upper surface of the first low refractive organic layer protrudes more than an upper surface of the protruding pattern part in the thickness direction.

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.

A touch sensor includes: a first insulating layer disposed on a substrate; a plurality of first touch sensing cells disposed on the first insulating layer and coupled to each other in a first direction by first coupling patterns; a plurality of second touch sensing cells disposed on the first insulating layer and coupled to each other in a second direction by second coupling patterns; and a second insulating layer disposed on the first touch sensing cells and the second touch sensing cells. At least one of the first insulating layer or the second insulating layer includes a piezoelectric material.
