About in front of the diffuser plate has simple analyzed some of its species, so thus we also know that it has five kinds, then analyze the diffuser plate diffusion principle, in fact, before facing the spread of the light diffuser principle have some simple analysis, of course there are some different between places.
 

So to understand the diffusion principle of a diffusion plate you have to know two things, one is the reflection principle and the other is the refraction principle. So the principle of reflection is: when light is shot from one medium to a smooth interface of another medium, part of the light is reflected by the interface, and part of the light is refracted in another medium through the interface. The incident Angle of light is equal to the reflected Angle, and the reflected light and the incident light in the same plane on both sides of the normal line. The principle of refraction is that the refracted ray is located in the plane of the incident light and the normal line, and the refracted light and the incident light are on both sides of the normal line.
 

The principle of the diffuser is by chemical or physical means, using light in ACTS encountered two medium by different refractive index, refraction, reflection and scattering of the physical phenomena, by PMMA, PC, PS, PP, such as base material and adding inorganic or organic light diffusion based agent, or by micro structure characteristics of the array on the surface of the base material artificially adjust the light, the light refraction, reflection and scattering of different direction, to alter the path of light, scattered fully incident light color to produce optical diffusion effect, optical diffuser plate is widely used in liquid crystal display, LED lighting, and imaging system.
 

Of course, the above diffusion principle of the diffusion plate only need to understand, do not need to fully understand, the follow-up will continue to analyze other aspects of the diffusion plate information.
