Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate, a luminescent functional layer and a pixel definition layer, wherein the array substrate comprises a base substrate and a thin film transistor array; the luminescent functional layer comprises first electrodes, a luminescent material layer and second electrodes, and the first electrodes are positioned at a first electrode layer; the thin film transistor array is arranged at one side of the base substrate; the first electrode layer is arranged at one side of the thin film transistor array away from the base substrate and comprises a plurality of first electrodes; the pixel definition layer is arranged at one side of the first electrode layer away from the base substrate and comprises a plurality of opening areas and a plurality of non-opening areas surrounding the opening areas; the first electrodes are at least positioned in the opening areas, at least parts of the first electrodes have first areas and second areas, and the light transmittance of the second areas is greater than the light transmittance of the first areas; and a fingerprint recognition array comprises a plurality of fingerprint recognition sensors and is arranged at one side of the first electrode layer away from the pixel definition layer. The display panel and the display device disclosed by the invention can improve the fingerprint recognition accuracy.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] Fingerprints are inherent to everyone. With the development of technology, a variety of display devices with fingerprint recognition functions have appeared on the market, such as mobile phones, tablet computers, and smart wearable devices. Before operating a display device with a fingerprint recognition function, the user only needs to touch the display device with a finger to perform authorization verification, which simplifies the authorization verification process. Moreover, with the gradual increase in the application scenarios of the fingerprint recognition function, the fingerprint recognition area is gradually changed from Some areas have evolved into full-screen recognition. [0003] In the existing display devices based on optical fingerprint recognition technology, the fingerprint re...
