Abstract

The embodiment of the invention discloses a display panel, a display device and a preparation method of the display panel. The display panel comprises a first substrate base plate; a plurality of fingerprint identification units located at one side of the first substrate; a plurality of collimation hole units which are located at sides, deviating from the first substrate, of the fingerprint identification units; each collimation hole unit comprises at least one layer of shading part; each shading part is provided with a light through hole; the vertical projections of the light through holes ofthe shading parts on the plane where the first substrate is located are at least partially overlapped; a collimation hole is formed in the area where each light through hole is located; the verticalprojections of the collimation holes on the plane where the first substrate is located are at least partially overlapped with the vertical projections of the fingerprint identification units on the plane where the first substrate is located; and a reflection unit is arranged on the side walls of the collimation holes. According to the display panel provided by the embodiment of the invention, theeffect of improving the fingerprint identification precision is achieved.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a display device, and a method for manufacturing the display panel. Background technique [0002] Due to the uniqueness and invariance of each person's fingerprint, the technology of using fingerprint as identification has developed rapidly in recent years. For example, in the field of mobile phones, as more and more people have requirements for narrow borders and full screens of mobile phones, optical fingerprint recognition technology has become more and more widely used. Before operating the display device with the fingerprint identification function, the user only needs to touch the fingerprint identification unit of the display device with a finger to perform authority verification, which simplifies the authority verification process. However, the fingerprint recognition accuracy of the display device with fingerprint recogni...
