Problems solved by technology

[0003] In the prior art, the fingerprint identification unit of the liquid crystal display panel is usually arranged on the backlight module. To install the fingerprint identification unit on the backlight requires opening holes in the backlight module, which affects the uniformity of the brightness of the backlight. The corresponding method is used for optical compensation, and it is also necessary to make collimation holes so that the fingerprint identification unit can obtain accurate fingerprint images

Abstract

The invention discloses a display panel and a display device. The display panel includes a color filter substrate and an array substrate arranged oppositely, and a liquid crystal layer sandwiched therein; the color filter substrate includes a first substrate, and the first substrate is close to a side of the array substrate. A black matrix is ​​provided on one side, and the black matrix includes a plurality of first openings and a plurality of second openings; the side of the first substrate away from the array substrate is provided with a light adjustment layer, and the part of the light adjustment layer corresponding to the first opening is used to The light that enters the light adjustment layer from the side of the light adjustment layer away from the first substrate converges toward the first opening; the array substrate includes a second substrate, and the side of the second substrate close to the color filter substrate is provided with a plurality of photosensitive elements and a plurality of pixels The electrodes, the photosensitive element are arranged corresponding to the first opening, and the pixel electrodes are arranged corresponding to the second opening; in the direction perpendicular to the first substrate, the light adjustment layer, the first opening and the photosensitive element are at least partially overlapped. The invention realizes fingerprint recognition under the screen, and has high recognition precision.

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] With the rapid development of display technology, display panels with fingerprint recognition function have gradually spread into people's lives. Fingerprint recognition is widely used in the display screens of electronic devices such as mobile phones, personal digital assistants, and computers. Fingerprints are invariable features of the human body that are inherently unique and distinguishable from others. They consist of a series of ridges and valleys on the surface of the skin of the fingertips. Details such as ends, arches, tent arches, left-handed, right-handed, spiral or double-turned, which determine the uniqueness of the fingerprint pattern. [0003] In the prior art, the fingerprint identification unit of the liquid crystal display panel is usually arranged on the backlight module, an...
