Abstract

The invention discloses an array substrate, a preparation method thereof, a fingerprint recognition method and a display device. The array substrate comprises a substrate body, multiple pixel units and multiple fingerprint recognition units, wherein the pixel units and the fingerprint recognition units are located in a display region of the substrate body. By arranging the fingerprint recognitionunits in the display region of the array substrate and making orthographic projection of through holes in the fingerprint recognition units on the substrate body not overlap with orthographic projection of the pixel units and all wires connected with the pixel units on the substrate body, sheltering of the fingerprint recognition units by all films of the pixel units is avoided while the apertureratio of the array substrate is not influenced, and therefore it is convenient for the array substrate to achieve a fingerprint recognition function.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to an array substrate, a preparation method thereof, a fingerprint identification method and a display device. Background technique [0002] Fingerprints are inherently unique and invariable features that can be distinguished from others. It consists of a series of ridges and valleys on the skin surface of the fingertips. The details of the composition of these ridges and valleys determine the uniqueness of the fingerprint pattern. The display panel with fingerprint identification function developed therefrom has been used in personal identity verification, increasing the information security of the display device. [0003] In the prior art display panel with fingerprint recognition function, the fingerprint recognition area is set in the non-display area of ​​the display panel, that is, on the basis of the display area of ​​the display panel, in order to enable the di...
