Working principle of PS Diffuser Plate
How does PS diffuser plate work? Why can it be used by diffusion? To know this, we need to know the working principle of PS diffuser plate. The working principle of PS diffuser plate is as follows.
Before we understand the diffusion principle of PS diffuser plate, we must know two principles, one is reflection principle, the other is refraction principle. Then the reflection principle is: when light shoots from one medium to the smooth interface of another medium, one part of the light is reflected by the interface, and the other part of the light is refracted through the interface in another medium. The incident angle of the 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 principle of refraction is that the refracted light lies 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 refracted angle is a constant.
PS diffuser plate with such principle can be widely used in LCD, LED lighting and imaging display system.
