3.Diffusion plate
The main function of the chirped diffuser plate is to uniformly guide the light from the light guide plate to make the light distribution more uniform. When the light hits the diffusion point, the reflected light will diffuse to various angles, and then it will be emitted from the front of the light guide plate. The light guide plate is made to emit light uniformly using various dense and different diffusion points, and the brightness of the light guide plate is improved. Can also play a role in fuzzy outlets. The diffusion plate generally uses acrylic 2.0 sheet or PC material, and the PS material is almost the same. Acrylic has lower cost, slightly higher light transmittance than PC, and weak anti-aging performance; PC is slightly more expensive, but has strong anti-aging performance. After the diffuser plate is installed, the dots cannot be seen, and the light transmittance should be about 90%. The acrylic light transmittance is 92%, the PC is about 90%, and the PS is about 88%. Manufacturers can choose the material of the diffusion plate according to demand. At present, most manufacturers use acrylic materials.
