Abstract

The present invention provides a display substrate, a manufacturing method thereof, and a display device. The display substrate includes: a base, a light-shielding layer and a plurality of light-emitting units arranged in the display area of ​​the base, and a plurality of imaging units are arranged on the light-shielding layer. A small hole, the orthographic projection of the imaging small hole on the substrate does not overlap with the orthographic projection of the effective light-emitting area of ​​the light-emitting unit on the substrate, and at least the surface of the light-shielding layer close to the light-emitting unit Some areas are uneven. In the present invention, since at least part of the surface of the light-shielding layer near the light-emitting unit is uneven, the reflectivity of the surface of the light-shielding layer can be reduced, and stray light can be reduced from being reflected by the light-shielding layer into the imaging aperture or other light leakage places on the light-shielding layer. , so as to enter the fingerprint sensor, making the collected fingerprints clearer and improving the accuracy of fingerprint recognition.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] In-screen fingerprint recognition technology is currently a research hotspot. In-screen fingerprint recognition can further compress the size of the lower frame of the display screen, which is conducive to the realization of full-screen, and also has better oil resistance, water stain resistance, and dust resistance. Among various in-screen fingerprint recognition schemes, the design scheme of the pinhole imaging principle has attracted wide attention due to its high resolution. [0003] However, in the current design scheme of pinhole imaging, there is the problem of stray light, which leads to blurred collected fingerprints and inaccurate fingerprint recognition. Contents of the invention [0004] In view of this, the present invention provides a display substrate, a man...
