Abstract

The invention discloses a display panel and a display device. The display panel includes: an array substrate including pixel electrodes, the pixel electrodes including at least two sub-electrodes and sub-electrode connecting parts; A domain region and a junction region located at the junction of adjacent domain regions; a liquid crystal layer; a second light-shielding structure, arranged on the array substrate and / or the color filter substrate, and the second light-shielding structure overlaps the junction region on the orthographic projection of the color filter substrate and a plurality of photosensitive units, the photosensitive unit includes a collimation hole and a photosensitive element, the collimation hole is arranged in the second light-shielding structure, the photosensitive element is arranged on the array substrate, and the orthographic projection of the photosensitive element on the color filter substrate and the collimation hole are in The orthographic projection on the color filter substrate is overlaid. According to the display panel of the embodiment of the present invention, under the same actual aperture 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...
