Basic qauv ntawm diffusion membrane

Nws muaj kev ua haujlwm ntawm lub teeb diffusing, du txhais tau hais tias lub teeb yuav tawg rau ntawm nws qhov chaw, thiab lub teeb yuav muag thiab sib npaug; Cov qauv yooj yim ntawm ntau-shun diffusion zaj duab xis yog coated ntawm ob sab ntawm pob tshab substrate xws li PET. Astigmatism hais. Tam sim no, nws feem ntau yog hais txog lub teeb pom kev zoo ntawm qhov chaw siv rau LCD module. Hauv cov qauv teeb pom kev zoo, nws tsuas yog ua lub luag haujlwm hauv kev kho lub diffusion lub kaum sab xis, uas yuav ua rau lub teeb hluav taws xob ntau ntxiv, tab sis txo cov teeb pom kev hauv ib cheeb tsam, uas yog, txo qhov ci. Tom qab lub teeb pom kev zoo yog diffused los ntawm cov khoom siv diffusion, nws tuaj yeem dhau los ua lub teeb ci thib ob nrog thaj tsam loj dua, zoo dua qub thiab ruaj khov chromaticity.
