Abstract

The invention relates to a reflective film, and specifically relates to a high-luminance diffusion silver-plated reflective film applied to a liquid crystal backlight source and a preparation method thereof. In order to improve the luminance of the reflective film in the existing backlight module and solve the problems of the existing backlight module such as LED lamp shadow and uneven luminance, the invention provides a high-luminance diffusion silver-plated reflective film and a preparation method thereof. The reflective film comprises, in sequence from bottom to top, a base layer, a silver-plated layer, an acrylate polymer layer, a protective layer, and a diffusion coating. The diffusion coating includes adhesive and diffusion particles. The diffusion particles are composed of large-diameter diffusion particles and small-diameter diffusion particles. The diffusion particles are glued onto the surface of the protective layer by the adhesive. By using the reflective film provided by the invention, the problem that the luminance of the traditional reflective film is inadequate is solved, the use of diffusion films is reduced, and the development towards a large, thin, light and low-cost flat-panel display can be satisfied.

Description

technical field [0001] The invention relates to a reflective film, in particular to a high-brightness diffused silver-plated reflective film used in a liquid crystal backlight source and a preparation method thereof. Background technique [0002] The liquid crystal display itself cannot emit light and must display images with the aid of a backlight source. Therefore, the development of the backlight module has played a crucial role in the development of the liquid crystal display. With the increase in the demand for large-scale liquid crystal displays, the cost of the backlight module The proportion is also increasing. Therefore, backlight modules are striving to improve in terms of lightness, thinness, low power consumption, high brightness and low cost. [0003] The backlight module is assembled from a light source, a lampshade, a reflective film, a light guide plate, a diffuser film, a brightness enhancement film and an outer frame. The reflective film of the backlight ...
