Problems solved by technology

If the amount of light received by the fingerprint recognition sensing unit (that is, the photosensitive device) is large, the accuracy of fingerprint recognition is high, and if the amount of light received by the photosensitive device is small, the accuracy of fingerprint recognition is low.

Abstract

The invention discloses a display panel and a display device. The display panel comprises a display area including a light-emitting area and a non-light-emitting area. An array layer includes a substrate layer and a plurality of metal lines arranged in the non-light-emitting area. The display layer is arranged above the array layer and consists of a plurality of light-emitting devices including anodes, light-emitting layers and cathodes. A support structure is formed between each two adjacent light-emitting devices in one non-light-emitting area. A fingerprint recognition area is arranged in the display area and includes a plurality of light-sensitive devices arranged at the side, away from the display layer, of the array layer. The support layers include first support structures arrangedin the fingerprint recognition area; the orthographic projection of the first support structures on the substrate layer are first projections; orthographic projections of the metal lines on the substrate layers are second projections; and the overlap areas of the first projections and the second projections are not less than 80% of the first projection area. Therefore, the light amount that is needed by fingerprint recognition and is received by the light-sensitive devices is increased and the accuracy of fingerprint recognition 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] 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. Fingerprints are inherent and unique to everyone, and the use of fingerprint recognition functions can improve the safety factor of the display device. When a user operates a display device with a fingerprint recognition function, the user can perform authorization verification by touching the fingerprint recognition sensor of the display device with a finger, which simplifies the authorization verification process. [0003] The optical fingerprint recognition technology generally detects the light reflected to the fingerprint recognition unit through the touch subject (such as a finger), that is, deter...
