Abstract

The invention provides a liquid crystal display panel and a display device, and the liquid crystal display panel comprises a first black matrix which is provided with a plurality of first through holes; a first micro-lens array which comprises a plurality of first micro-lens units, a second micro-lens array which comprises a plurality of second micro-lens units, wherein the plurality of first micro-lens units and the plurality of second micro-lens units are arranged in a one-to-one correspondence manner; and a photosensitive sensor array which comprises a plurality of photosensitive sensors; wherein the plurality of second micro-lens units and the plurality of first through holes are arranged in a one-to-one correspondence manner, the plurality of first through holes and the plurality of photosensitive sensors are arranged in a one-to-one correspondence manner, and each first through hole, the orthographic projection of the second micro-lens unit arranged corresponding to the first through hole and the orthographic projection of the photosensitive sensor arranged corresponding to the first through hole on the array substrate are at least partially overlapped. According to the liquid crystal display panel provided by the invention, the area of fingerprint signals can be reduced through the combination of the double-layer lens, so that the area of an area for collecting the fingerprint signals is reduced, and the display aperture ratio is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a liquid crystal display panel and a display device. Background technique [0002] The liquid crystal display panel has a layered structure, which consists of a cover plate, a black matrix and a filter layer, a liquid crystal layer, a thin film transistor array substrate, a polarizer, and a backlight from top to bottom. There are generally two types of fingerprint recognition technologies applied to liquid crystal display panels, which are under-screen fingerprint recognition technology and in-screen fingerprint recognition technology. Among them, the in-screen fingerprint recognition technology has gradually become a future development trend because it can further reduce the size of the LCD screen. However, in the current in-screen fingerprint recognition technology, the area where the fingerprint signal is collected is too large, resulting in a low aperture ratio of...
