The working principle of diffuser acrylic sheet

How does the diffuser acrylic sheet work and why can it be used by diffusion? The working principle of the

diffuser acrylic sheet is as follows.

     Two principles must be known before understanding the diffusion principle of diffusion plate, one is the

reflection principle and the other is the refraction principle. Then the reflection principle is: when light is

emitted from one medium to the smooth interface of another medium, some light is reflected by the interface,

and the other light is refracted in another medium through the interface. The incident angle of light is equal

to the reflection angle, and the reflected light and the incident light are on both sides of the normal in the same

plane. The refraction principle is that the refracted light is located in the plane between the incident light and

the normal, the refracted light and the incident light are on both sides of the normal, and the sine ratio of the

incident angle and the refraction angle is a constant.

Diffusion plates based on this principle can be widely used in liquid crystal display, LED lighting and imaging

display systems.
