Abstract

The invention discloses and provides a touch panel, a manufacturing method of the touch panel, and a display device. The touch panel comprises at least one flexible substrate and a touch electrode, aplurality of concave-convex fine structures are formed in the surface of the flexible substrate, and at least part of the touch electrode is formed on one or more concave-convex fine structures of theflexible substrate. Therefore, the contact area between the touch panel and an optical transparent adhesion layer is increased to improve the adhesion effect of the two by increasing the specific surface area of the flexible substrate without sacrificing the overall rebound resilience of the flexible touch panel, meanwhile, the overall stress level is also reduced to reduce the stress borne on acover film caused by bending, the phenomena that the optical transparent adhesion layer between the touch panel and other film layers of the touch panel produces bubbles, is cracked or layered and thelike are solved, so that the anti-bending capability of a foldable display module is improved on the whole.

Description

technical field [0001] The present disclosure relates to the field of touch control. Specifically, the present disclosure relates to a touch panel, a manufacturing method thereof, and a display device. Background technique [0002] Existing flexible touch display panels usually stack film layers such as cover film, touch panel (TSP) including flexible substrate and touch electrodes, optically transparent adhesive layer (OCA), circular polarizer (CPOL), back film, etc. in sequence. When it is folded, due to the stress between the film layers, OCA bubbles, cracks, and delamination are prone to occur between the TSP and the film layers, especially in the folded area. In severe cases, the covering film will break. [0003] At present, the thickness of OCA is usually increased to enhance the interlayer adhesion between TSP and the flexible touch display panel and reduce the overall stress level, so as to reduce the stress on the cover film. However, an increase in the thicknes...
