Abstract

A method for preparing diffusion film includes mixing multiple ball form scattering particle and multiple non-ball form scattering particle in solution with binder for forming a mixed liquid and then coating mixed liquid on a transparent base plate.

Description

technical field [0001] The present invention relates to a diffusion film and its manufacturing method, in particular to a backlight module, which can increase the stacking density per unit volume by stacking spherical scattering particles and non-spherical scattering particles, thus increasing the The number of refractions of light, and then the diffusion film and its manufacturing method that can achieve better light diffusion effect. Background technique [0002] With the advancement of electronic technology, especially the prevalence of portable electronic products in daily life, there is an increasing demand for displays that are thin, light, small, and low in power consumption. Among them, Liquid Crystal Display (LCD) has been used in various electronic products due to its advantages of low power consumption, low heat generation, light weight, and non-radiation, and has gradually replaced Traditional cathode ray tube display (Cathode Ray Tube Display, CRT Display). ...
