Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises an array substrate, a display unit and a fingerprint recognition unit, wherein the array substrate comprises a substrate body and a display driving circuit formed on the substrate body; the display unit is arranged on the array substrate and located at the side, away from the substrate body, of the display driving circuit; and the fingerprint recognition unit comprises a light sensing unit, the light sensing unit is arranged on the array substrate and located at the side, away from the substrate body, of the display driving circuit, and a vertical projection of the light sensing unit on a plane, where a light-emitting function layer of the display unit is located, is located between adjacent short edges of the light-emitting function layer of the display unit. Through the embodiment, influences of light rays emitted by the display unit on the fingerprint recognition unit are reduced, and fingerprint recognition precision is improved.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] Since fingerprints are inherent to each person, they are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, before operating the display device with the fingerprint recognition function, the user only needs to touch the fingerprint recognition sensor of the display device with a finger to perform authority verification, which simplifies the authority verification process. [0003] In the existing display device, the fingerprint identification sensor is directly arranged in the display area of ​​the display panel, because part of the light emitted by the display unit in the display area of ​​the display panel will directly irradiate t...
