PC Diffusion Board Product Principle
Jan 28, 2019
The light transmittance of the product is 80% or more, and the ordinary PC milk whiteboard is only 20%; through the diffusion of the diffusion plate, the entire surface of the board forms a uniform light-emitting surface without forming a dark area, and no residue is formed on the screen. The image makes the picture more realistic and achieves a transparent and transparent visual effect.
When light strikes a smooth interface from one medium to another, a portion of the light is reflected by the interface and another portion of the light is refracted through the interface in the other medium. The angle of incidence of light is equal to the angle of reflection, and the reflected light is on either side of the normal in the same plane as the incident light. This is the law of reflection. The refracted ray is in accordance with the law of refraction: the refracted ray is in the plane of the incident light and the normal, the refracted light and the incident light are on both sides of the normal, and the ratio of the incident angle to the sine of the refraction angle is a constant. Both the law of refraction and the law of reflection are the basis of geometric optics. They not only lay the foundation for theoretical research, but also for the development of optical technology, especially diffusion plates, and the design of optical products.
PC diffusion plate is a special processing product based on ordinary PC single-layer board. It is a new type of optical material for uniform surface illumination. The effect of PC diffusion plate is good and bad, and it is closely related to the content and composition of diffusion particles. The smaller the content of the diffusing particles, the higher the light transmittance and the lower the haze. The diffusing plate is generally white, translucent, and the more diffusing particles, the lower the light transmittance and the higher the haze. The diffusing plate is generally milky white and opaque, so it can be seen that the transmittance and haze of the diffusing plate are inversely proportional, that is, the two cannot be combined. The Korean ISO has continuously developed and innovated the diffusion masterbatch through 20 years. The best effect of diffusion uniformity is achieved by adjusting the surface structure of the diffusion plate and the diffusion masterbatch.
