Abstract
The invention discloses a display panel and a display device. The display panel comprises an array substrate; a color film substrate; a liquid crystal layer which is clamped between the array substrate and the color film substrate; and a plurality of photosensitive units which are arranged on the array substrate, wherein the photosensitive surface of each photosensitive unit faces the color film substrate, the color film substrate comprises a black matrix layer, and the black matrix layer comprises a plurality of first openings; slit units and first light filtering units covering the slit units are arranged in the first openings, each slit unit comprises two slits which allow light to penetrate through and interfere with each other, and the light sensing units can receive the light penetrating through the first light filtering units and the slit units. According to the display panel provided by the embodiment of the invention, the light passing through the first light filtering units and the slit units can form the light intensity enhancing regions and the light intensity counteracting regions which are arranged at intervals on the plane where the light sensing surface is located,and the photosensitive units receive the light passing through the first filtering units and the slit units, so that the information crosstalk between the adjacent photosensitive units can be reduced.
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] Display panel integrated fingerprint recognition technology is a panel integration technology that provides fingerprint recognition capability without reducing the effective display area of the display panel. Existing display panels usually integrate an optical fingerprint identification unit. 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 fingerprint recognition unit. The fingerprint identification unit can generate different identification information according to the difference of light reflection between the valleys and ridges of the fingerprint path, thereby being able to identify different fingerprint path information. [0003] In the prior art, the number of fingerprint recognition units integrated on the d...
