Diffusing film having the role of diffusion of light, i.e. light in the surface thereof will occur scattering, soft light evenly spread out; the basic structure of the majority of the diffusion film on a transparent substrate such as PET coated on both sides optical astigmatism particles.
In the material composition of the LCD backlight, the diffusion film is almost one of the essential materials.
Diffusion membrane structure: diffusion layer + base layer + isolation layer.
The substrate layer is generally highly transparent PET film, thickness: 28,38,50,75,100,125,150,188 UM |
