Abstract

The invention discloses a display panel and a display device. The invention belongs to the technical field of display, the display panel comprises a substrate, an array layer, a fingerprint recognition layer and a color film substrate, the color film substrate at least comprises a first shading layer, the first shading layer comprises a plurality of first shading parts, the fingerprint recognitionlayer comprises a plurality of photosensitive devices, and the orthographic projections of the photosensitive devices to the substrate and the orthographic projections of the first shading parts to the substrate are at least partially overlapped; a plurality of imaging holes are formed in the first shading layer, and the orthographic projection of the imaging holes to the substrate is located within the range of the orthographic projection of the photosensitive device to the substrate; and at least part of light on the side, deviating from the underlayer substrate, of the color film substrateis projected to the photosensitive device through the imaging hole. The display device comprises the display panel. The display panel can be thinned, the resolution of the display panel can be prevented from being affected, and the fingerprint recognition effect of the display panel can be improved by utilizing the principle of pinhole imaging.

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] 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 a display device with a fingerprint recognition function, the user only needs to touch the display device with a finger to perform authorization verification, which simplifies the authorization verification process. Evolved into full-screen recognition. [0003] The display screen in the prior art generally adopts the scheme of attaching a fingerprint identification module under the screen. The fingerprint identification module is relatively thick for the imaging space and related components. At the same time, the occupation of space also a...
