Problems solved by technology

[0003] For the above attachment methods, since the fingerprint module is directly attached to the back film of the display module, the display module is attached by frame glue and fingerprint module. Attached two times of lamination stress; and because the thermal expansion coefficient and Young's modulus of the frame glue, edge sealant, and display module back film are inconsistent, the indentation after lamination and reliability will increase, making the point screen During the display process, indentations appear in the area of ​​the fingerprint module, which affects the display effect

Abstract

The invention discloses a display panel, a display device and an attaching method of a fingerprint module. The display panel comprises a display module; a heat dissipation film layer is arranged on aback film of the display module, a first opening is formed in the heat dissipation film layer, a composite film layer is arranged in the first opening, and the fingerprint module is attached to the composite film layer; the composite film layer comprises a supporting layer and a buffer layer which are bonded with each other, and the supporting layer is close to the fingerprint module. According tothe technical scheme provided by the embodiment of the invention, the composite film layer is arranged as the connecting layer between the fingerprint module and the display module, the composite film layer absorbs impact stress through the buffer layer and fixes and supports the fingerprint module through the supporting layer, and indentations caused by fitting pressure can be eliminated; according to the further provided attaching method, the attaching stress borne by the display module can be effectively reduced, the influence on the display module is avoided, the problem of mold printingduring laminating of the fingerprint module is effectively solved, and the yield of products is increased.

Description

technical field [0001] The invention generally relates to the display field, and in particular to a bonding method of a display panel, a display device and a fingerprint module. Background technique [0002] In the existing under-screen fingerprint recognition technology in the display field, the process of attaching the fingerprint module is generally as follows: the frame glue is attached to the back film of the display module under a certain pressure; secondly, the fingerprint module is attached with a certain pressure. It is attached to the frame glue; finally, the edge sealing glue is dotted around the fingerprint module to fix the fingerprint module. [0003] For the above-mentioned attachment method, since the fingerprint module is directly attached to the back film of the display module, the display module is subjected to two lamination stresses of the frame adhesive attachment and the fingerprint module attachment; and due to the frame adhesive and edge sealant The...
