Display screen cover board and fabrication method therefor, arc-shaped display screen and terminal

Abstract

Embodiments of the invention provide a display screen cover board and a fabrication method therefor, an arc-shaped display screen and a terminal. The display screen cover board comprises a transparent substrate, a plasma layer and a protective layer, wherein the transparent substrate comprises a flat panel part and a cambered surface part which extends from the flat panel part; the plasma layer covers the cambered surface part; and the protective layer is attached to the flat panel part and the plasma layer. According to the embodiments of the invention, by covering the cambered surface part of the transparent substrate with the plasma layer, the adhesive force between the cambered surface part and the protective layer can be increased due to the plasma layer, so that generation of air bubbles in the attaching position between the protective layer and the cambered surface part can be further avoided; and therefore, warping, falling off and the like of a protective film can be prevented, thereby improving the quality of the display screen cover board.

Description

technical field [0001] The invention relates to the technical field of terminal screens, in particular to a display screen cover and a manufacturing method thereof, a curved display screen and a terminal. Background technique [0002] There are several forms of curved cover glass. There are 3D screens whose entire screen is curved, and there are also 2.5D screens with a flat center and curved edges. The advantages of both are fuller visual sense and more beautiful , At the same time, its surface is smooth, and it feels better when you take it. [0003] However, when the curved cover glass is installed, almost all of it protrudes outside, that is, it is located on the outside of the electronic product as a whole. In case of accidents, the cover glass is more likely to come into contact with hard objects, so it is prone to scratches and even breaks The phenomenon. In order to further protect the cover glass, a protective film is generally attached to the surface of the cover...

AI Technical Summary

Problems solved by technology

However, in the prior art, air bubbles are likely to be generated at the position where the protective film adheres to the curved surface of the edge of the curved cover glass, resulting in defects such as warping and falling off of the protective film.
