Problems solved by technology

[0002] With the continuous development of LCD screen technology, the screen resolution is getting higher and higher (2K-4K-8K), and the size is getting bigger and bigger. Correspondingly, more requirements are put forward for the viewing angle of the optical film group and the improvement of the adaptability to the high-definition LCD screen. High requirements, increased viewing angle of the screen, improved shielding performance, improved anti-interference performance, and brightness must meet the requirements, which brings difficulties to the traditional method of making the enhancement film: in the prior art, the main method is to increase the back coating fog The degree of increase increases part of the viewing angle and improves the shielding performance, but after this treatment, the luminance drops a lot and cannot meet the brightness requirements

Abstract

The invention belongs to the technical field of optical film materials, and discloses a prism lens, which consists of a back coating, a base film and a prism layer, and is characterized in that the prism layer is formed by curing and molding a molding glue, wherein the molding glue contains nano material particles. The invention discloses application of the prism lens, wherein the prism lens is used as an upper brightness enhancement film of an optical module. According to the prism lens, the shielding performance and the screen display effect can be improved, the visual angle of a screen is increased, the prism lens can better adapt to a high-definition screen, it is guaranteed that the screen brightness and the anti-interference performance meet the requirements, the adding amount of microbeads in a back coating is reduced, and the cost is also reduced. When the prism lens is used as an upper brightness enhancement film, the prism lens can be well matched with 4K and 8K screens, the shielding performance and the screen display effect can be improved, the visual angle of the screen is increased, the prism lens better adapts to a high-definition screen, and it is guaranteed that the screen brightness and the anti-interference performance meet the requirements.
