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, and the display panel comprises a color film substrate and an array substrate disposed opposite to each other, and a liquid crystal layerinterposed there-between, wherein the color filter substrate comprises a first substrate, one side of the first substrate adjacent to the array substrate is provided with a black matrix that includesa plurality of first openings and a plurality of second openings; one side of the first substrate away from the array substrate is provided with a light adjustment layer, and a portion of the light adjustment layer corresponding to the first opening is used for concentrating the light entering the light adjustment layer from one side of the light adjustment layer away from the first substrate toward the first opening; the array substrate includes a second substrate, and one side of the second substrate near the color film substrate is provided with a plurality of light sensing elements and a plurality of pixel electrodes, the light sensing elements are disposed corresponding to the first opening, and the pixel electrodes are disposed corresponding to the second opening; and the light adjustment layer, the first opening and the light sensing elements at least partially overlap in a direction perpendicular to the first substrate. The invention realizes the 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 specifically, to a display panel and a display device. Background technique [0002] With the rapid development of display technology, display panels with fingerprint recognition functions have gradually spread in people's lives, and fingerprint recognition is widely used in display screens of electronic devices such as mobile phones, personal digital assistants, and computers. Fingerprint is an invariable feature that is unique and distinguishable from others. It consists of a series of ridges and valleys on the skin surface of the fingertips. The details of these ridges and valleys usually include the bifurcation of ridges, the Details such as ends, arches, tented arches, left-handed, right-handed, helical or double-handed, these details determine the uniqueness of the fingerprint pattern. [0003] In the prior art, the fingerprint identification unit of the liquid crystal di...
