Difuzijski filmovi/papir Primjena
Feb 22, 2022
The diffuser film is a component of the LCD backlight module, which mainly diffuses the light of the light guide plate, so that the line light source (CCFL) or the point light source (LED) can be distributed into a uniform surface light source. Generally, LCD needs 2 diffusion films, 1 upper diffusion film and 1 lower diffusion film. Because the lower diffusion film is close to the light guide plate, the light transmittance is high and the scattering degree is not high. The film also has the function of removing the pattern of the prism sheet and protecting the prism sheet. The upper and lower diffuser films scatter the light to achieve the effect of uniform light diffusion.
Općenito, tradicionalni difuzijski film uglavnom dodaje kemijske čestice supstratu difuzijskog filma kao čestice raspršivanja, dok postojeća difuzijska ploča ima čestice raspršene između slojeva prstiju stabla, tako da će se svjetlost lomiti u dva smjera kada prolazi kroz difuzijski sloj. Istodobno, svjetlost će proći kroz mnoge fenomene loma, refleksije i raspršenja, što će rezultirati efektom optičke difuzije.
