Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology, and can avoid the interference of reflected light from adjacent areas during fingerprint identification, thereby improving the accuracy of fingerprint identification. The display panel includes a base substrate, and the display area of ​​the display panel is provided with a plurality of sub-pixels, and each sub-pixel includes an opening area, wherein the opening area is the light-emitting area of ​​the sub-pixel; at least part of the display area is a fingerprint identification area, and at least part of the sub-pixels The pixel is located in the fingerprint identification area, and the fingerprint identification area is provided with at least one spacer, the orthographic projection of the spacer on the base substrate does not overlap with the orthographic projection of the opening area on the base substrate, and one spacer The object extends from the first edge of the fingerprint identification area to the second edge of the fingerprint identification area, and the first edge and the second edge are two opposite edges of the fingerprint identification area in the row direction. The above-mentioned display panel is used to realize screen display.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] For the display panel with fingerprint recognition function, in order to better realize the full-screen design and avoid the fingerprint recognition area occupying the space of the non-display area, the display area can be reused as the fingerprint recognition area by using the under-screen fingerprint technology. When the display area is multiplexed as a fingerprint identification area, multiple fingerprint identification units are also arranged in the position corresponding to the fingerprint identification area in the display panel. When fingerprint identification is performed, the light emitted by the light source is reflected by the finger and enters the fingerprint in a specific area. In the identification unit, the fingerprint identification unit further identifies valleys and ridges of the fi...
