Embodiment Construction

[0050] In order to further illustrate the display panel, the manufacturing method thereof, and the display device provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.

[0051] see figure 1 , as described in the background art, when making a display device with a fingerprint recognition function in the related art, the specific process includes: attaching the sealant layer 3 to the display substrate 1 under a certain pressure, and then attaching the fingerprint recognition module 5 is attached to the frame-sealing adhesive layer 3 under a certain pressure, and finally an edge-sealing adhesive layer 4 is formed around the fingerprint identification module 5 to bond the side of the fingerprint identification module 5 to the frame-sealing adhesive layer 3 to realize the The fingerprint identification module 5 is firmly fixed on the display substrate 1 . However, since the frame sealant laye...

Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device, relates to the technical field of display, and aims to solve the problem that an indentation is easy to appear on the surface of a display substrate attached with a fingerprint identification module after a reliability test. The display panel includes: a display substrate; the heat dissipation structure is arranged on the display substrate, the orthographic projection of the heat dissipation structure on the display substrate is located in the non-display area, and an opening corresponding to the display area is defined by the heat dissipation structure on the non-light-emitting side of the display substrate; the frame sealing glue layer is arranged on the surface, back on to the display substrate, of the heat dissipation structure, and the orthographic projection of the frame sealing glue layer on the display substrate surrounds the orthographic projection of the opening on the display substrate; the fingerprint recognition module is arranged on the surface, back on to the display substrate, of the frame sealing glue layer, and the orthographic projection of the fingerprint recognition module on the display substrate covers the display area; and the edge sealing adhesive layer is arranged at the periphery of the fingerprint identification module. The display panel provided by the invention is used for displaying.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the continuous development of display technology, more and more display devices have the function of fingerprint recognition. The structure of this display device generally includes: a display substrate, a fingerprint recognition module adhered to the non-light-emitting side of the display substrate by sealing glue, The specific working process is: when a finger touches the display substrate on the light-emitting side of the display substrate, the light emitted by the display substrate can be irradiated on the finger, reflected by the fingerprint on the finger, and transmitted to the display substrate through the pre-made small hole on the display substrate. The fingerprint recognition module realizes the recognition of the fingerprint. [0003] In the prior art, wh...
