Abstract

The invention discloses a display panel and a display device. The display panel includes an organic light-emitting display panel, a fingerprint recognition module, and an angle-limiting film; the organic light-emitting display panel includes an array substrate and a plurality of organic light-emitting structures located on the array substrate The fingerprint identification module is located in the display area of ​​the array substrate away from the organic light-emitting structure, including the first substrate, at least one fingerprint identification unit, and performs fingerprint identification according to the light reflected from the touch body to the fingerprint identification unit; the angle limiting film is located in the organic light-emitting structure. Between the luminescent display panel and the fingerprint identification module, among the light reflected to the fingerprint identification unit via the touch body, the light whose incident angle relative to the angle-defining film is greater than the transmission angle of the angle-defining film is filtered out. Through the technical solution of the present invention, the crosstalk phenomenon caused by light reflected from different positions of the touch body irradiating to the same fingerprint identification unit is effectively avoided, and the accuracy and precision of fingerprint identification are improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] Since fingerprints are inherent to each person, they are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. 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 his finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display device with fingerprint identification function, the fingerprint identification module generally detects the light irradiated to the fingerprint identification unit through the touch body (such as a finger), that is, the rid...
