Abstract

The invention discloses a display panel and a display device. The display panel comprises a display module and a fingerprint recognition module, wherein the display module comprises an array base plate and a plurality of pixel units positioned on the array base plate; the fingerprint recognition module is positioned at one side, far away from the pixel units, of the array base plate; the fingerprint recognition module comprises a first base plate and at least one fingerprint recognition unit positioned on the first base plate; the fingerprint recognition unit is used for performing fingerprintrecognition according to light rays reflected to the fingerprint recognition unit through a touch main body; the array base plate comprises a plurality of light transmission regions and a plurality of non-light transmission regions; the array base plate also comprises a plurality of metal wires; the ratio of the wire width of at least one metal passing wire corresponding to at least one light transmission region to the wire width corresponding to the arrangement part of the non-light-transmission region is smaller than 1. By using the technical scheme, compared with the prior art, the displaypanel and the display device have the advantages that the wire width of the at least one metal passing wire corresponding to at least one light transmission region is reduced; the fingerprint recognition signal quantity of the fingerprint recognition unit is 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] 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 the display device with the fingerprint identification function, the user only needs to touch the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] The display panel with fingerprint identification function generally sets the fingerprint identification module under the display module. recognition function. However, the opaque film layer such as the metal layer in the display module occupies most of the projected area of ​​the display module, which makes th...
