Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes a display module and a fingerprint recognition module; the display module includes a base substrate, a plurality of pixel drive circuit units located on one side of the base substrate, and at least two types of metal wiring extending along a first direction, a plurality of The pixel driving circuit units are arranged in a matrix along the first direction and the second direction, and there is a first gap between two adjacent pixel driving circuit units in the first direction; the display panel provided by the embodiment of the present invention is provided by setting at least The two types of metal traces include multiple first-type metal traces and multiple second-type metal traces, the first-type metal traces and the second-type metal traces are located on different layers, and in the first gap area, at least The overlapping vertical projections of a first-type metal trace and a second-type metal trace on the base substrate can reduce the influence of the metal trace on the light transmittance of the display panel, thereby improving the fingerprint recognition signal strength.

Description

technical field [0001] The present invention relates to display technology, in particular to a display panel and a display device. Background technique [0002] Each person's skin texture (including fingerprints) is different in patterns, breakpoints and intersections, which are unique and remain unchanged throughout life. Accordingly, we can match a person with his fingerprint, and verify his real identity by comparing his fingerprint with the pre-saved fingerprint data. This is fingerprint recognition technology. With the development of electronic integrated manufacturing technology, optical fingerprint recognition technology in fingerprint recognition technology has begun to enter our daily life, and has become the most in-depth research, the most widely used and the most mature technology in biometrics. [0003] At present, the optical fingerprint identification technology is usually combined with the display technology, so that the display panel not only has a normal d...
