Figure 2-2 (a murb) shows the scattering effect of parallel light passing through silicone particles with diameters of 2 μ m and 3 μ m,
For the light diffusion films embossed on different surfaces, the haze increases to different degrees. The haze of the diffusion film of the cylindrical lens array increases rapidly, while that of the microlens array increases slowly.
The diffusion effect of cylindrical lens diffusion films doped with different concentrations of organosilicon particles.
Light transmittance and haze are two important indexes to characterize the properties of light diffusion films. The former determines the intensity of light passing through, while the latter determines the uniformity and diffusion effect of line and surface light sources
1. Characterization parameters of basic optical properties of light diffusion films In order to accurately describe the diffusion effect of the light diffusion film, firstly,
the demand for diffusion films used in these electronic products is greatly increased. At present, the domestic demand for optical diffusion film is conservatively estimated to be more than 1000 million m2, but most of them rely on imports from the United States, Japan and South Korea.
