Abstract

The invention relates to a display screen, a preparation method of the display screen and electronic equipment. The display screen comprises a display panel, a photoelectric sensor and a dimming layer, a TFT circuit layer is formed on a substrate of the display panel, an organic light-emitting layer comprises an OLED light-emitting unit, the photoelectric sensor is formed at the position, corresponding to a fingerprint detection area, of the TFT circuit layer and is used for fingerprint detection, the dimming layer is located on the side, opposite to the substrate, of the TFT circuit layer, the dimming layer comprises an optically thinner medium part and an optically denser medium part connected with the optically thinner medium part, the optically thinner medium part covers the OLED light-emitting unit, and the optically denser medium part covers the photoelectric sensor; when light emitted by the OLED light-emitting unit enters a finger located in the fingerprint detection area, at least part of light reflected to the optically denser medium part from the finger is totally reflected on the connecting face of the optically denser medium part and the optically thinner medium part and then enters the photoelectric sensor. According to the display screen, the preparation method of the display screen and the electronic equipment, the fingerprint identification efficiency is improved while the electronic equipment is lightened and thinned.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a display screen, a preparation method of the display screen and electronic equipment. Background technique [0002] With the development of electronic technology, electronic devices such as mobile phones and tablet computers have become an indispensable part of people's daily life and work. [0003] At present, the fingerprint recognition module is either installed on the side of the electronic device facing away from the display surface for fingerprint recognition, or is set on the side of the display screen facing away from the display surface, that is, the under-screen fingerprint module. When the fingerprint recognition module is arranged on the side of the electronic device facing away from the display surface, the fingerprint recognition is exposed to the appearance surface of the electronic device, affecting the overall aesthetics of the appearance....
