Abstract

The embodiment of the invention discloses a display panel. A plurality of fingerprint recognition units are arranged on the side, facing a liquid crystal layer, of an array substrate, a color film substrate comprises a substrate, a color resistance layer, a black matrix and a plurality of collimation structures, and the collimation structures are arranged on the side, close to the liquid crystal layer, of the substrate; each collimation structure comprises at least two layers of light shielding units which are arranged in a stacked mode, and each light shielding unit is provided with a light transmitting opening corresponding to the fingerprint recognition unit. In the thickness direction of the color film substrate, the color film substrate is provided with a light-transmitting channel corresponding to the fingerprint recognition unit, and the light-transmitting channel comprises light-transmitting openings in the at least two layers of shielding units. A shielding unit and the black matrix are arranged on the same layer. The shielding units and the black matrix are arranged on the same layer, and the effect of thinning the display panel is achieved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] During the research and practice of the prior art, the inventors of the present application found that in existing display devices such as smart phones, the fingerprint identification sensor is usually placed under the display screen and can only be identified in a fixed area. The disadvantage is that the fingerprint module is placed under the display screen, separated from the display screen, occupying the space of the mobile phone module, the battery and other components need to be designed to avoid, and the thickness of the module is also relatively thick. Contents of the invention [0003] An embodiment of the present application provides a display panel that can be thinned and realize full-screen fingerprint recognition. [0004] An embodiment of the present application provides a display panel, which includes: ...
