Abstract

A display device including a fingerprint sensor is provided. The display device includes a substrate including a fingerprint area, and the fingerprint area includes a first area and a second area. A light-emitting element layer is disposed on the substrate and includes a light-emitting element. A sensor layer is disposed on the substrate and comprises a light sensor. The light emitting elements include a first light emitting element disposed in the first area and a second light emitting element disposed in the second area. During the fingerprint sensing period, the first light-emitting elementemits light, and the second light-emitting element does not emit light.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2019-0110917 filed on September 6, 2019, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present invention relates to a display device, and more particularly, to a display device with a fingerprint sensor. Background technique [0003] Recently, as display devices such as smartphones or tablet personal computers (PCs) are used in various fields, a biometric information authentication method using a user's fingerprint or the like has been widely used. In order to provide a fingerprint sensing function, a fingerprint sensor may be provided in such a manner as to be built in or attached to a display device. [0004] A light sensing type fingerprint sensor may include a light source and a light sensor. The light sensor may receive reflected light from the user's fingertip, and then may acquire corresponding fingerprint information. There may be a possi...
