Three-dimensional curved surface panel, three-dimensional curved surface touch panel and three-dimensional curved surface touch display panel using the same

Abstract

The invention relates to a three-dimensional-curved-surface panel. The three-dimensional-curved-surface panel comprises a covering layer and a protective film. The covering layer is provided with a three-dimensional curved surface. The height of the three-dimensional curved surface changes from the edges of the covering layer to the central area of the covering layer. The protective film is attached to the surface of the covering layer. The protective film is provided with shear lines. The shear lines extend from the edges of the covering layer to the central area of the covering layer. Because the shear lines extending from the edges of the covering layer to the central area of the covering layer are formed on the protective film, thee protective film can be well attached to the covering layer of the three-dimension curved surface. In this way, external influences on the covering layer protected by the protective film can be reduced or avoided; and for instance, external foreign matter is prevented from entering the three-dimensional-curved-surface panel, and the covering layer is prevented from being scratched.

Description

technical field [0001] The invention relates to a three-dimensional curved panel, in particular to a protective film for the three-dimensional curved panel. Background technique [0002] In traditional smart devices, a transparent covering layer is usually arranged on the touch module or the touch display module to protect the touch module or touch display module whose structure is relatively fragile or easily affected by the outside world. However, with the popularization of smart devices, users have higher requirements for the appearance design of smart devices, such as smart devices with a transparent covering layer with a three-dimensional curved surface shape, so that smart devices have a streamlined and three-dimensional appearance. Design, too, came into being. In addition to providing a smart device with a beautiful appearance, the transparent covering layer with a three-dimensional curved surface shape can also be used to enlarge the display components, and in the ...

Problems solved by technology

In addition, the gap formed during the bonding process may also form air bubbles due to the thermal expansion and contraction of the transparent layer and the protective layer after sealing, so that the protective layer cannot be sealed with the transparent layer, or the protective layer cannot be in contact with the transparent layer. Adhesion and rebound may further cause the protective layer to peel off from the transparent layer

[0004] It can be seen that the above-mentioned existing structure obviously still has inconvenience and defects, and needs to be further improved.

In order to solve the above problems, related fields have tried their best to find a solution, but no applicable method has been developed for a long time.
