A display panel and electronic device

Abstract

Embodiments of the present invention provide a display panel and electronic equipment. The display panel includes: an array substrate, and a plurality of organic light-emitting structures located on the array substrate; at least one fingerprint recognition unit, located on the side of the organic light-emitting structure close to the array substrate In the area; the fingerprint recognition unit is used to perform fingerprint recognition according to the light reflected to the fingerprint recognition unit via the touch body; the organic light-emitting structure includes red organic light-emitting structure, green organic light-emitting structure and blue organic light-emitting structure; in the fingerprint recognition stage, the red organic light-emitting structure The light emitting structure and / or the green organic light emitting structure emit light as the light source of the fingerprint recognition unit; the light transmission area of ​​the red organic light emitting structure and / or the green organic light emitting structure as the light source of the fingerprint recognition unit to the display side away from the display panel is smaller than that of the blue organic light emitting structure The light-transmitting area of ​​the structure toward the display side away from the display panel. The invention realizes the improvement of the accuracy of fingerprint identification.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and electronic equipment. Background technique [0002] Since fingerprints are inherent to each person, they are unique. With the development of science and technology, various display devices with fingerprint recognition functions and electronic devices including display devices, such as mobile phones, tablet computers and smart wearable devices, have appeared on the market. In this way, before operating the display device with fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display devices with fingerprint recognition function, the fingerprint recognition module is often arranged in the non-display area of ​​the display panel, or on the surface opposite to the ligh...

AI Technical Summary

Problems solved by technology

When the organic light-emitting structure in the display panel is used as the light source of the fingerprint identification module, part of the light emitted by the organic light-emitting structure is directly irradiated on the fingerprint identification unit in the fingerprint identification module without being reflected by the touching subject (such as a finger). Noise is formed, which affects the accuracy of fingerprint recognition by the fingerprint recognition module
