Optical prism film for small-size backlight module

Abstract

The optical prism film comprises a prism film body, the outer surface of the upper end of the prism film body is fixedly connected with a prism structure, first OCA glue is fixedly connected between the prism film body and the prism structure, the lower end of the prism film body is fixedly connected with a lower-layer protective film, and the lower-layer protective film is fixedly connected with the lower-layer protective film. A lower-layer protective film is fixedly connected between the prism film main body and the lower-layer protective film, an upper-layer protective film is fixedly connected to the upper end of the prism structure, a structure protective frame is arranged between the prism structure and the upper-layer protective film, and an adhesive mounting layer is fixedly connected to the lower end of the lower-layer protective film. According to the optical prism film for the small-size backlight module, the upper-layer protective film, the lower-layer protective film and the reinforcing base material are arranged, the film can be better protected conveniently, the use performance of the prism film is improved, the light transmittance and dispersity of the prism film can be improved, and the optical performance is more excellent.

Description

technical field [0001] The invention relates to the field of optical prism films, in particular to an optical prism film for small-sized backlight modules. Background technique [0002] Optical prism film is a support device used in liquid crystal display to improve the front brightness of the display screen. According to the principle of geometric optics, the light emitted from the backlight passes through the prism film and the circulation of the backlight system, and finally converges in the front view direction and exits. , so as to achieve the brightening effect. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of optical prism film. [0003] The existing optical prism film has certain disadvantages in use. First, the prism film cannot be easily installed during use. The performance of the prism film is poor, and it is prone to damage, which is not conducive to people In addition, the as...

Problems solved by technology

[0003] The existing optical prism film has certain disadvantages in use. First, the prism film cannot be easily installed during use. The performance of the prism film is poor, and it is prone to damage, which is not conducive to people In addition, the astigmatism effect of the prism film is poor, which brings certain adverse effects to people's use process. Therefore, we propose an optical prism film for small-size backlight modules.
