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.
Go ginearálta, cuireann an scannán idirleathadh traidisiúnta go príomha cáithníní ceimiceacha leis an tsubstráit scannán idirleathadh mar cháithníní scaipthe, agus tá cáithníní scaipthe idir na sraitheanna méaróg crann ar an pláta idirleathadh atá ann cheana féin, mar sin déanfar an solas a athraonadh i dhá threoir nuair a théann sé tríd an gciseal idirleathadh. Ag an am céanna, rachaidh an solas faoi go leor feiniméin athraonta, machnaimh agus scaipthe, rud a fhágann go mbeidh éifeacht idirleathadh optúil.
