Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen and a display device. Background technique [0002] Fingerprint is a unique feature of the human body. It is composed of ridges and valleys on the skin surface of the fingertips. The pattern formed by these ridges and valleys determines the uniqueness of the fingerprint, and its uniqueness and complexity are sufficient to meet the identification requirements. With the rapid development of display technology, display panels with a fingerprint recognition function have gradually spread in people's lives. [0003] At the same time, with the rapid development of display devices, users have higher and higher requirements for screen-to-body ratio, which makes the full-screen display of display devices attract more and more attention from the industry. In order to increase the screen-to-body ratio as much as possible, now In the prior art, there has been a solution to...
