Problems solved by technology

[0004] Usually, the array substrate includes a plurality of photosensitive structures, and each photosensitive structure is used to receive the light reflected back from the corresponding fingerprint identification area directly above it. If the crosstalk light reflected from the adjacent fingerprint identification area is reflected on the photosensitive structure, It will affect the size of the photocurrent generated by the photosensitive structure, and then affect the accuracy of fingerprint recognition

Abstract

The embodiment of the invention discloses an array base plate, a display panel and a display device. The array base plate includes: a substrate base plate; a first light-shielding layer, which is located at one side of the substrate base plate; a light-sensitive structure, which is located at one side that is of the first light-shielding layer and faces away from the substrate base plate; a secondlight-shielding layer, which is located at one side that is of the light-sensitive structure and faces away from the substrate base plate; and a light-shielding structure, which is located between the first light-shielding layer and the second light-shielding layer. In a direction perpendicular to the substrate base plate, the light-shielding structure surrounds the light-sensitive structure, andthe light-shielding structure includes at least a first light-shielding sub-part and a second light-shielding sub-part. The first light-shielding sub-part is located at one side close to the first light-shielding layer. The first light-shielding sub-part and the second light-shielding sub-part are prepared and formed by using different preparation processes. According to the technical solution provided by the invention, crosstalk light rays can be prevented from entering the light-sensitive structure, accuracy of fingerprint recognition is improved, at the same time, the light-shielding structure includes the first light-shielding sub-part and the second light-shielding sub-part, and preparation technology difficulty of the light-shielding structure can be reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to an array substrate, a display panel, and a display device. Background technique [0002] At present, in-screen fingerprint recognition, that is, embedding a fingerprint recognition device into the display area, is a research hotspot in the current display field. Embedding the fingerprint recognition device from the non-display area into the display area is conducive to improving the screen-to-body ratio of the display. [0003] Existing fingerprint identification technologies include optical fingerprint identification technology, semiconductor silicon fingerprint identification technology and ultrasonic fingerprint identification technology. Among them, the optical fingerprint recognition technology generally uses a photodiode as the light-sensing structure. Its working principle is: the reflected light formed after the light is reflected by the touch ...
