The Role And Use Of Reflective Film

Its reflectivity affects the brightness of the display. The reflective film can be used under the tube and the light guide. Some companies use some special techniques to produce a highly efficient reflective film with a reflection efficiency close to 100%. Except at the tube. High-reflection film, the reflective film under the light guide plate is especially important, and requires a special particle structure to match the printing point of the light guide plate, not only to reflect light, but also to make the reflected light relatively uniform. With these special reflection films, it is not necessary By changing the design and the mold, the center brightness of the liquid crystal display can be improved by nearly 30%. The characteristics of the optical film are: the surface is smooth, the interface between the layers is geometrically divided; the refractive index of the film layer can jump at the interface. However, it is continuous in the film layer; it can be a transparent medium or an absorbing medium; it can be normal or uniform, and the film used in practice is much more complicated than the ideal film. It is because: when preparing, the optical properties and physical properties of the film deviate from the bulk material, and the surface and interface are rough, resulting in diffuse scattering of the light beam; mutual penetration between the film layers forms a diffusion interface. Due to film growth, structure, stress, forming anisotropic film; film layer having a complex time effect.
