Terminal device, screen, cover plate structure and manufacturing method of cover plate structure

By setting a hard coating, composite material layer and optical adhesive layer in the cover plate structure, a buffer layer is directly formed on the rigid layer, which solves the problem of insufficient impact resistance of the flexible cover plate, achieving higher impact resistance and longer bending life, while improving processing efficiency and reducing costs.

Abstract

The embodiment of the invention provides a terminal device, a screen, a cover plate structure and a manufacturing method of the cover plate structure. In the embodiment of the invention, the first buffer layer is formed on the surface of the first rigid layer to form the first composite material layer. And respectively forming a hard coating and a first optical adhesive layer on two opposite sides of the first composite material layer to obtain the cover plate structure. In the process, the laminating process of the optical transparent adhesive tape is reduced. Moreover, through the process of attaching the first optical adhesive layer to the display layer of the screen, better flatness can be guaranteed, the display layer and components below the display layer are protected, and the impact resistance is improved. Therefore, when the display panel is applied to a screen or a terminal device with a screen, the processing efficiency of the whole production and manufacturing can be improved, the processing cost can be reduced, and the reliability of a product can be improved.
