Protective film applied to curved display screen

Abstract

The invention discloses a protective film applied to a curved display screen, and relates to the technical field of protective films. The protective film sequentially comprises a UV curing layer, a base film layer, an elastomer layer, an organic silicon pressure-sensitive layer and a release layer from top to bottom. The thickness of the protective film applied to the curved display screen is 150-400 [mu] m. According to the protective film applied to the curved display screen, the protective film sequentially comprises the UV curing layer, the base film layer, the elastomer layer, the organicsilicon pressure-sensitive adhesive layer and the release layer from top to bottom, and the impact resistance and the bendability of the protective film can be improved by arranging the elastomer layer and the protective film is easier to attach; the organic silicon pressure-sensitive adhesive layer is cooperatively used so that the adhesion of the protective film is improved, the problem that the edge of the curved screen is warped is effectively solved, the protective film has hardness and flexibility, and the protective film has the characteristics of good adhesion with the curved screen and no warping.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a protective film applied to curved display screens. Background technique [0002] With the development of science and technology, especially the replacement of smart phones, display screens are no longer limited to flat screens. Curved screens are more and more popular with consumers because of their better viewing comfort and visual effects. The majority of electronic manufacturers also Electronic products with curved display screens have been introduced one after another, and therefore curved display screen protective films have emerged as the times require. [0003] The traditional protective film is used to fit the flat display screen. Due to the special structure of the curved display screen, it is difficult to perfectly fit the curved display screen with the traditional protective film. The edges are not firm and easy to warp. . Existing protective films for bon...

Problems solved by technology

[0004] The first type is the curved tempered film, which has good drop resistance, but has high hardness and high brittleness, and white edges (peeling) are prone to appear on the edge of the curved screen, which cannot fit the curved screen well;

[0005] The second type, the hydrogel film, is made of amorphous polymer materials. It has a high degree of adhesion and self-healing of fine scratches. Patent application document CN201810539235.6;

[0006] The third type, UV optical film, has a high degree of adhesion to curved screens, but the product has low hardness and poor durability
