Problems solved by technology

[0003] There are many metal patterns on the existing display substrate. Because the metal patterns are opaque, they will block the light, resulting in a low transmittance of the display substrate. When the display substrate is used in fingerprint recognition, the reflective information of the valleys and ridges of the fingerprint will be The loss is relatively large, which affects the accuracy of fingerprint recognition

Abstract

The invention provides a display substrate, a fingerprint identification panel, a fingerprint identification method and a display device, and belongs to the technical field of display. The display substrate comprises a first metal pattern and a second metal pattern, wherein the first metal pattern and the second metal pattern are located on a substrate body and arranged on different layers, and the orthographic projection of the first metal pattern on the substrate body and the orthographic projection of the second metal pattern on the substrate body are at least partially overlapped. According to the technical scheme, the transmittance of the display substrate can be improved, and then the fingerprint recognition precision is improved.

Description

Technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a fingerprint recognition panel, a fingerprint recognition method and a display device. Background technique [0002] The existing fingerprint recognition panel includes a display substrate and a fingerprint recognition module. The fingerprint of the finger reflects the light irradiated on the fingerprint, and the reflected light passes through the display substrate and is received by the fingerprint recognition module. Light to identify fingerprints. [0003] There are many metal patterns on the existing display substrates. Because the metal patterns do not transmit light, they will block the light, resulting in low transmittance of the display substrate. When the display substrate is used in fingerprint recognition, the reflection information of the valley ridge of the fingerprint will be affected. The loss is more, which affects the accuracy of fingerprint reco...
