Problems solved by technology

[0002] The flexible display panel contains multiple film layers and has a bending area. In the bending area, due to the inconsistency of the bending capabilities between adjacent film layers, the separation of the film layers usually occurs, especially for displays with static bending areas. In the panel, the static bending area is in the bending state for a long time, and the separation of the film layer is more serious. For example, the adjacent touch layer in the flexible display panel is inconsistent with the polarizer touch layer and the polarizer. In the process of use or during the reliability test, the phenomenon of film layer separation often occurs

Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0026] Aiming at the phenomenon of film layer separation often occurring in the bending area of ​​the current display panel, the applicant conducted in-depth research and found that changing the structure of the adhesive layer or increasing the adhesion of the adhesive layer between the film layers still cannot be well changed. The phenomenon of film layer se...

Abstract

The invention discloses a polarizer and a manufacturing method thereof, a display panel and a display device, wherein the polarizer comprises: a polarizer layer and at least one non-functional layer, and an elastic hollow microstructure is wrapped in a predetermined area of ​​the non-functional layer The spherical structure, the preset area is used to correspond to the bending area of ​​the display panel; the elastic hollow microspheres are embedded in the bending area of ​​the non-functional layer, and when the non-functional layer is deformed by external force, fine Cracks, the elastic hollow microspheres absorb the stress of the non-functional layer through deformation, which can effectively enhance the elasticity of the area. When the display panel is bent, the stress can be effectively released to prevent the separation of the film layer. Hollow structure, with high specific surface area, good thermal stability, and good heat insulation ability, can effectively avoid the damage of the thermal expansion stress of the material to the module structure during high-temperature static bending, and effectively reduce the damage to the module structure during high-temperature static bending. The phenomenon of film layer separation.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a polarizer and a manufacturing method thereof, a display panel and a display device. Background technique [0002] The flexible display panel contains multiple film layers and has a bending area. In the bending area, due to the inconsistency of the bending capabilities between adjacent film layers, the separation of the film layers usually occurs, especially for displays with static bending areas. In the panel, the static bending area is in the bending state for a long time, and the separation of the film layer is more serious. For example, the adjacent touch layer in the flexible display panel is inconsistent with the polarizer touch layer and the polarizer. In the process of use or during the reliability test, the phenomenon of film layer separation often occurs. Contents of the invention [0003] For this reason, the present invention proposes a polarizer and a manufactur...
