Abstract

The embodiment of the invention provides a display panel and a fingerprint identification display device. The display panel comprises a first base plate and a second base plate that are opposite to each other. The first base plate includes a first substrate; and a plurality of light sensing units are arranged at one side, being close to the second base plate, of the first substrate. The second base plate includes a second substrate; at least one shading layer is arranged at one side, being close to the first base plate, of the second substrate and includes a plurality of opening parts; and theopening parts and the light sensing units are at least overlapped partially in a first direction perpendicular to a light emitting surface of the display panel. In addition, the display panel furtherincludes transparent resin layers that are used for filling the opening parts and are in direct contact with the second substrate at the opening parts, wherein the refractive indexes of the transparent resin layers are smaller than that of the second substrate. Therefore, the light receiving range of the light sensing unti can be ensured and the height of the collimating hole can be reduced; andthe process number of the collimating hole is reduced.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a fingerprint recognition display device comprising the display panel. 【Background technique】 [0002] With the popularization of mobile display products, information security has attracted people's attention. 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 Ends, arches, tented arches, left-handed, right-handed, spiral or double-turn details, these details determine the uniqueness of the fingerprint pattern. Due to the advantages of uniqueness, difficulty in duplication, and security of fingerprints, fingerprint recognition technology has been widely used in mobile display products in recent years, as a way of identity authentication and acces...
