Abstract

The invention discloses a display device. The display device comprises a display panel and a side-entry fingerprint recognition light source, the display panel comprises an array substrate and an opposite substrate which are oppositely arranged, the opposite substrate comprises a first shading layer, and the first shading layer comprises a plurality of first opening parts; the array substrate comprises a second shading layer and a light sensing element, the light sensing element is located on the side, close to the first shading layer, of the second shading layer, and the light sensing elementand the first shading layer are at least partially overlapped in the direction perpendicular to the display panel; the display panel further comprises a plurality of pixel units, each pixel unit comprises a plurality of sub-pixels, each sub-pixel comprises a light-transmitting area, in the direction perpendicular to the display panel, the light-transmitting areas and the first opening parts are at least partially overlapped, and fingerprint recognition light reaches the light sensing element through the light-transmitting areas to be subjected to fingerprint recognition. The first shading layer and the second shading layer are arranged on the two sides of the light sensing element, so that other light sources except the fingerprint recognition light source are prevented from entering thelight sensing element, and the fingerprint recognition precision is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display device. Background technique [0002] With the popularization of mobile display products, information security has attracted people's attention. Due to the advantages of uniqueness, difficulty in duplication, and security of fingerprints, fingerprint recognition technology has been widely used in mobile display products in recent years, as a way of identity authentication and access control, making mobile display products safe and easy to operate performance is greatly improved. [0003] The fingerprint identification in the display panel is to realize the difference of different fingerprint information received by the optical element through the reflectivity difference between the valley and the ridge of the fingerprint, and form a fingerprint image. However, some light sources other than the fingerprint recognition light source will also enter the ...
