Basic structure of diffusion membrane

It has the function of diffusing light, du means that the light will scatter on its surface, and the light will be soft and evenly spread out; the basic structure of the multi-shun diffusion film is coated on both sides of a transparent substrate such as PET. Astigmatism particles. At present, it mainly refers to the backlight light source part applied to the LCD module. In the backlight structure, it mainly plays a role in correcting the diffusion angle, which will increase the light radiation area, but reduce the light intensity per unit area, that is, reduce the brightness. After the luminous light source is diffused by the diffusion material, it can become a secondary light source with larger area, better uniformity and stable chromaticity.
