Abstract

The embodiment of the invention discloses a display panel and a display device, wherein the display panel comprises a first substrate, a second substrate, a liquid crystal layer, a light isolation structure and a plurality of fingerprint identification units; wherein the first substrate and the second substrate are oppositely arranged, and the liquid crystal layer and the light isolation structureare respectively arranged between the first substrate and the second substrate; the plurality of fingerprint identification units are arranged on the first substrate, and the vertical projection of the light isolation structure on the first substrate is arranged between the vertical projections of two adjacent fingerprint identification units on the first substrate, and the fingerprint identification unitsare used for receiving the reflected light formed by the reflection of a touch body and carrying out fingerprint identification on the basis of the reflected light. The display panel can improve the fingerprint identification precision of the fingerprint identification units.

Description

technical field [0001] Embodiments of the present invention relate to fingerprint identification 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 display ...
