Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a fingerprint recognition module, a shading layer, a light emitting device layer and a touchfunction layer which are sequentially arranged in a stacked mode. The shading layer comprises a plurality of imaging small holes; the touch function layer comprises a first touch area and a second touch area. The first touch area is not overlapped with the imaging small hole recognition area, the second touch area is overlapped with at least one imaging small hole recognition area, the reflectivity of the second touch area is smaller than that of the first touch area, or the light transmittance of the second touch area is larger than that of the first touch area; or the light transmission uniformity of the second touch area is higher than that of the first touch area; or the second touch area comprises a hollow area. Luminous flux and light uniformity of the imaging small hole and the fingerprint recognition module after passing through the second touch area are improved, meanwhile, light reflection of the touch function layer of the second touch area is reduced, and fingerprint recognition sensitivity of the fingerprint recognition module is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of fingerprint identification, and in particular, to a display panel and a display device. Background technique [0002] Fingerprints are inherent and unique 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. . In this way, before operating the display device with fingerprint recognition function, the user only needs to touch the fingerprint recognition module of the display device with his finger to perform authority verification, which simplifies the authority verification process. [0003] A plurality of small holes for imaging can be set in the existing display device with fingerprint recognition function, and the light emitted by the light-emitting layer is reflected by the finger and then imaged through the small holes...
