Abstract

The embodiment of the invention provides a display panel and a display device, relates to the technical field of display, and is used for improving the sensitivity of fingerprint identification. The display panel includes: a substrate; a sub-pixel positioned on one side of the substrate; a fingerprint sensor which is located on the side, away from the light emitting side of the display panel, of the substrate; and a reflection part which is located on the side, close to the light-emitting side of the sub-pixel display panel, of the fingerprint sensor in the direction perpendicular to the plane where the substrate is located, wherein the reflection part is used for enhancing the intensity of light entering the fingerprint sensor.

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] In recent years, with the continuous development of display technology, more and more display devices adopt fingerprint recognition to realize user privacy protection. When a user operates a display device with a fingerprint identification function, he only needs to touch the display screen with his finger to realize authority verification, and the operation is simple. [0003] When the existing display panel with fingerprint identification function performs fingerprint identification, a fingerprint sensor needs to be installed in the display panel, and the light emitted by the light source is reflected into the fingerprint sensor through finger reflection. Identification of fingerprints. However, based on the structure of the existing display panel, the sensitivity of fingerprint identification is...
