Kev tshuaj xyuas cov qauv thiab kev ua haujlwm tseem ceeb ntawm cov polarizer rau LCD. Polarizer yog ib qho ntawm cov khoom siv tseem ceeb ntawm cov kua siv lead ua kua (LCD), suav txog li 20 feem pua -30 feem pua ntawm nws cov nqi tsim khoom. Txawm li cas los xij, txij li kev tsim tshuab ntawm polarizer tau monopolized los ntawm Nyiv, Kaus Lim Qab Teb thiab lwm lub tebchaws, kev qhia txog polarizer muaj cov ntaub ntawv tsawg heev. Kab lus no siv cov polarizer rau TN LCD ua piv txwv, thiab qhia txog qee qhov teeb meem uas ntau tus neeg siv LCD polarizer muaj kev txhawj xeeb ntau dua.
Cov qauv ntawm cov polarizer
Polarizer yog ib hom yeeb yaj kiab kho qhov muag nrog kev ua haujlwm ntawm kev tsim lub teeb pom kev zoo, uas yog tsim los ntawm ntau txheej txheej polymer. Raws li qhov sib txawv siv txoj haujlwm ntawm cov kua siv lead ua kua, nws tuaj yeem muab faib ua ntu ntu (tseem hu ua daim ntawv pob tshab) thiab cov yeeb yaj kiab tsis zoo. Ob hom (tseem hu ua reflectors).
Cov ntaub ntawv thiab lub luag haujlwm tseem ceeb ntawm txhua txheej
Polarizing txheej: Nws yog ua los ntawm PVA (polyvinyl cawv) zaj duab xis tom qab dyeing thiab ncab. Cov txheej no yog qhov tseem ceeb ntawm cov polarizer, tseem hu ua thawj polarizing zaj duab xis. Cov txheej polarizing txiav txim siab qhov kev ua tau zoo ntawm polarization thiab kev xa tawm ntawm polarizer, thiab nws tseem yog qhov tseem ceeb uas cuam tshuam rau cov xim xim thiab qhov muag pom ntawm polarizer. Cov txheej txheem thev naus laus zis ntawm polarizing txheej tuaj yeem muab faib ua ob ntu ntawm dye series thiab iodine series raws li txoj kev dyeing. Raws li cov txheej txheem ncab, nws tuaj yeem muab faib ua ob ntu ntawm kev ncab qhuav thiab ntub ncab. Hloov nws cov khoom siv thiab kev siv thev naus laus zis tuaj yeem ua tiav txoj cai Kev Kho ntawm polarization, transmittance, xim thiab optical durability. TAC txheej: Cov txheej polarizing ua los ntawm PVA zaj duab xis yog yooj yim nqus dej, ploj thiab poob nws cov polarization kev ua tau zoo. Yog li ntawd, nws yog ib qho tsim nyog yuav tau siv TAC (triacetate cellulose ester) zaj duab xis nrog cov khoom siv kho qhov muag zoo thiab cov pob tshab ntawm ob sab kom cais cov dej noo thiab huab cua, tiv thaiv txheej polarizing. Siv TAC zaj duab xis nrog UV CUT thiab Anti-Glare muaj nuj nqi tuaj yeem ua rau cov tshuaj tiv thaiv ultraviolet polarizers thiab anti-glare polarizers.
Adhesive: Nws tuaj yeem muab faib ua zaj duab xis sab nplaum thiab tev zaj duab xis sab nplaum. Lub luag hauj lwm ntawm cov yeeb yaj kiab sab nplaum yog ua kom ruaj khov rau cov yeeb yaj kiab rau TAC zaj duab xis, thiab nws cov txheej txheem yuav tsum tsis pub rov ua dua. Lub tev zaj duab xis sab nplaum yog lub siab-rhiab nplaum nplaum, uas txiav txim siab qhov adhesion kev ua tau zoo thiab thaj ua haujlwm ntawm polarizer. Nws qhov kev ua tau zoo yog ib qho teeb meem txhawj xeeb tshaj plaws rau cov neeg siv LCD polarizer. Cais zaj duab xis: Nws yog PET (ethylene terephthalate) zaj duab xis coated nrog silicon txheej ntawm ib sab. Nws tsuas yog tiv thaiv lub siab-rhiab nplaum txheej. Nyob rau tib lub sijhawm, nws lub zog tev tawm yog qhov tseem ceeb heev rau LCD thaj. Kev ua haujlwm tau muaj qee yam cuam tshuam.
Cov yeeb yaj kiab tiv thaiv: Nws yog PE (polyethylene) zaj duab xis coated nrog EVA txheej (ethylene vinyl acetate copolymer) ntawm ib sab. Nws muaj viscosity tsawg thiab tiv thaiv qhov chaw ntawm TAC zaj duab xis.
Reflective film (reflective film): Nws yog ib sab PET zaj duab xis nrog txhuas vaporized. Tam sim no, feem ntau ntawm cov uas tsis yog-directional reflective vaporized txhuas zaj duab xis yog siv. Yog tias cov yeeb yaj kiab cuam tshuam tau hloov nrog cov yeeb yaj kiab transflective, lub transflective polarizer tuaj yeem ua tau. Tsis tas li ntawd, ntau yam kub-plated, silver-plated, thiab laser films kuj tseem siv tau los ua cov yeeb yaj kiab kom tau txais ntau yam xim tom qab thiab iav. Reflections thiab lwm yam teebmeem.
