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.
Ġeneralment, il-film tad-diffużjoni tradizzjonali prinċipalment iżid partiċelli kimiċi mas-sottostrat tal-film tad-diffużjoni bħala partiċelli tat-tifrix, filwaqt li l-pjanċa tad-diffużjoni eżistenti għandha partiċelli mxerrda bejn is-saffi tas-swaba tas-siġar, għalhekk id-dawl ikun rifratt f'żewġ direzzjonijiet meta jgħaddi mis-saff tad-diffużjoni. Fl-istess ħin, id-dawl se jgħaddi minn ħafna fenomeni ta 'rifrazzjoni, riflessjoni u tifrix, li jirriżulta fl-effett ta' diffużjoni ottika.
