Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises an array substrate which comprises a pixel electrode, and the pixel electrode comprises at least two sub-electrodes and sub-electrode connecting parts; a color film substrate comprising a first shading structure, the first shading structure being provided with a plurality of openings, and each opening comprising at least two domain regions and a junction region located at the junction of the adjacent domain regions; a liquid crystal layer; a second shading structure, arranged on the array substrate and / orthe color film substrate, and the orthographic projection of the second shading structure on the color film substrate being overlapped with the boundary area; a plurality of photosensitive units, comprising collimation holes and photosensitive elements, the collimation holes being formed in the second shading structure, the photosensitive elements beingarranged on the array substrate, and the orthographic projections of the photosensitive elements on the color film substrate being overlapped with the orthographic projections of the collimation holes on the color film substrate. According to the display panel provided by the embodiment of the invention, under the same actual aperture opening ratio, the actual liquid crystal efficiency of the display panel is higher, and the light transmittance is higher.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] Due to its uniqueness and quickness, fingerprint recognition technology is widely used in mobile phones, tablet computers and other terminal devices as a safe identification method for functions such as unlocking, payment, and message confirmation. [0003] In the terminal device, the fingerprint identification technology will be integrated in the display panel, so as to provide fingerprint identification capability without reducing the effective display area of ​​the display panel. Existing display panels usually integrate an optical fingerprint recognition unit, that is, a photosensitive unit is integrated. Wherein, the light emitted from the display panel is reflected on the surface of the finger and enters the display panel again to be received by the photosensitive unit. The photosensitive unit can generate dif...
