Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, at least one metal pattern and a pixel limiting layer, wherein the at least one metal pattern andthe pixel limiting layer are arranged in a non-light emitting region of the substrate, the pixel limiting layer covers the metal pattern, a plurality of through holes are formed in the pixel limitinglayer and penetrate through the pixel limiting layer, and perpendicular projection of the through holes on the substrate are not overlapped with perpendicular projection of the metal pattern on the substrate. The display panel also comprises a fingerprint identification unit and a fingerprint identification light source, a light ray emitted from the fingerprint identification light source is reflected by a touch main body and then forms reflection light irradiating the fingerprint identification unit so as to perform fingerprint identification, and the fingerprint identification unit is formed at one side, deviating from the pixel limiting layer, of the metal pattern. By the display panel, the shielding of an organic film layer on the reflection light is reduced, the transmittance of thereflection light is improved, so that the intensity of the reflection light acquired by the fingerprint identification unit is relatively high, and the fingerprint identification performance of the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to a display panel fabrication technology, and in particular, to a display panel and a display device. Background technique [0002] Each person's skin texture, including fingerprints, varies 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. Thanks to electronic integrated manufacturing technology and fast and reliable algorithm research, 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 in biometrics. technology. [0003] At present, the optical fingerprint identification technology is usually combined with the displa...
