Problems solved by technology

These coatings will block the light emitted by the fingerprint identification light source to a certain extent, and the light transmittance is low, which makes the intensity of the light collected by the fingerprint identification unit poor, and the fingerprint identification performance of the display panel is poor.

Abstract

The invention discloses a display panel and a display device. The display panel includes a base substrate; at least one metal pattern and a pixel definition layer formed in the non-luminous area of ​​the base substrate, the pixel definition layer covers the metal pattern, and the pixel definition layer is provided with a plurality of through holes penetrating the pixel definition layer , the vertical projection of the through hole on the substrate does not coincide with the vertical projection of the metal pattern on the substrate. The display panel also includes a fingerprint identification unit and a fingerprint identification light source. The light emitted by the fingerprint identification light source is reflected by the touch body to form reflected light and enters the fingerprint identification unit for fingerprint identification; the fingerprint identification unit is formed on the metal pattern away from the pixel definition layer. side. The invention reduces the shielding of the reflected light by the organic film layer, increases the transmittance of the reflected light, makes the intensity of the reflected light collected by the fingerprint recognition unit higher, and improves the fingerprint recognition performance of the display panel.

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...
