Introduction to PC diffusion board

Introduction to PC diffusion board

The PC diffusing agent can be evenly distributed in the plate, so that when the light passes through the plate, the effect of refraction, reflection and scattering occurs when the diffusing agent particles are encountered, so that the light can uniformly penetrate the plate without exposing the light source, and the point is reached. The change of the light source to the surface light source. PC light diffusing plate was first used in LED backlight module. Due to continuous advancement of technology, production cost is continuously reduced. At the same time, due to the excellent light diffusion effect, the application field of light diffusing plate based on PC endurance board is also extended. It is also widely used in the advertising industry and LED lighting products.

PC diffuser features:

<1> The PC diffusion plate is a uniform diffusion effect of light by continuously refracting, reflecting, and scattering between the chemical particles and the resin by the transmitted light. The utility model has the advantages of sufficient light transmittance and light diffusibility, high scratch resistance, low brightness, dot, glow, and imbalance of the light guide plate, and the uniformity of the backlight source by the light scattering effect of the plate. Degree, thus obtaining a new type of optical material for uniform surface illumination.

<2> The PC diffusion board is commonly used in a backlight device on the back of a liquid crystal display, and the backlight device provides illumination for a liquid crystal display that generates an image. The function of the diffuser is to convert the luminescence of the professional super bright fluorescent tube into diffuse, consistent two-way light and introduce it into the liquid crystal display without any loss of energy.

 <3> The transmittance of the PC diffusion plate is 60%-85%, and the ordinary PC whiteboard is only 20%; the diffusion and diffusion of light are increased by the diffusion of the diffusion plate, while shielding the light source and the glare source. It can make the light source emit uniform, soft and beautiful light, and achieve the comfortable effect of transparent opacity. And in the absence of a light source, it can also display excellent brightness; the light source can be fully scattered, and the LED light source is not penetrated, so that the entire board surface forms a uniform light-emitting surface without forming a dark area on the screen. No residual images will be formed, making the picture more realistic and achieving a crystal clear visual effect.

PC diffuser use:

1. Building applications: window, soundproof doors and windows, lighting cover, telephone booth, etc.

2. Advertising applications: light boxes, signboards, signs, display stands, etc.

3. Traffic applications: trains, cars, and other vehicle doors and windows, etc.

4. Medical applications: baby incubators, various surgical medical appliances, civilian products: bathroom facilities, handicrafts, cosmetics, brackets, aquariums, etc.

5. Industrial applications: instrument surface plates and covers, etc.

6. Lighting applications: fluorescent lamps, chandeliers, street lamp covers, etc
