Abstract

The invention discloses a display panel and a display device. The display panel comprises a display module and a fingerprint recognition module. The display module comprises an array substrate and a plurality of pixel units located on the array substrate; the fingerprint recognition module is located on the side, away from the pixel units, of the array substrate, the fingerprint recognition modulecomprises at least one fingerprint recognition unit, and the fingerprint recognition unit performs fingerprint recognition according to light reflected by a touch body to the fingerprint recognitionunits; the array substrate comprises a plurality of photic zones and a plurality of non-photic zones, the array substrate further comprises a plurality of metal wires, the metal wires include the metal wires arranged in the first extending direction and the metal wires arranged in the second extending direction, and the distances between the adjacent metal wires arranged at least in one extendingdirection are not identically equal, wherein the first extending direction is perpendicular to the second extending direction. According to the technical scheme, the probability that the metal wires are all located at the photic zones is lowered, and the fingerprint recognition semaphore is increased.

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...
