Tá feidhm an tsolais idirleata ag an mbileog diffuser, is é sin, beidh an solas scaipthe ar a dhromchla, agus beidh an solas idirleata go bog agus go cothrom; is é bunstruchtúr an chuid is mó de na scannáin diffuser ná cáithníní optúla diffuser a chóta ar an dá thaobh d'fhoshraith trédhearcach mar PET.
According to the classification of LCD displays, there are the following two categories: side projection type and direct type, in which the diffusion material used for side projection is called a diffusion film (or diffuser); in the direct type backlight source, two types of diffusion materials are applied. One is a diffuser film and the other is a diffuser plate.
The important indicators of the diffuser film are total light transmittance and haze.
At present, it mainly refers to the backlight light source part used in LCD modules. In the backlight structure, it mainly plays the role of correcting the diffusion angle, which increases the light radiation area, but reduces the light intensity per unit area, that is, reduces the brightness.
After the light source is diffused by the diffusing material, it can become a secondary light source with a larger area, better uniformity and stable chromaticity.
