Problems solved by technology

[0003] The light sensed by the fingerprint sensor unit in the prior art is the light reflected by the finger, but part of the reflected light will pass through the fingerprint sensor unit, and this part of the light cannot be used by the fingerprint sensor unit, which may reduce the fingerprint sensor. The luminous flux received by the sensing unit causes the reduction of fingerprint recognition sensitivity

Abstract

The invention discloses a display panel and a display device, and belongs to the technical field of display. A display panel comprises a substrate; a light shielding layer located at one side of the substrate, wherein the light shielding layer comprises a plurality of light shielding parts; a reflecting film layer which is located at one side, far away from the substrate, of the light shielding layer and comprises a plurality of reflecting parts; a photosensitive film layer which is located at one side, far away from the substrate, of the reflecting film layer, and comprises a plurality of fingerprint recognition units. The orthographic projection of the light shielding parts to the substrate is a first projection, and the orthographic projection of the reflecting part to the substrate isa second projection, and the orthographic projection of the fingerprint recognition unit to the substrate is a third projection, wherein the first projection, the second projection and the third projection are overlapped. The display device comprises the display panel. The luminous flux received by the fingerprint recognition unit can be increased, the recognition sensitivity of the fingerprint recognition unit is improved, and the fingerprint recognition effect of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] In recent years, with the popularity of mobile display products, information security has attracted much attention from consumers. Fingerprints are inherent to everyone. With the development of technology, a variety of display devices with fingerprint recognition functions have appeared on the market, such as mobile phones, tablet computers, and smart wearable devices. Before operating the display device with the fingerprint identification function, the user only needs to touch the display device with a finger to perform authority verification, which simplifies the authority verification process. Fingerprint recognition is unique and difficult to copy, and is widely used in unlocking and payment confirmation of mobile display products. Existing display panels with fingerprint recognition funct...
