Cov Khoom Thiab Ua Hauj Lwm Ntawm Txhua Txheej Ntawm Lcd Polarizer
Aug 13, 2018
Polarizing txheej: Nws yog tsim los ntawm dyeing thiab stretching PVA (polyvinyl cawv) zaj duab xis, uas yog qhov tseem ceeb ntawm polarizer, kuj hu ua polarizing zaj duab xis. Lub polarizing txheej txiav txim siab qhov kev ua tau zoo thiab kev hloov ntawm lub polarizer, thiab kuj yog ib feem loj ntawm cov xim tone thiab optical durability ntawm lub ncov qaumteb qabteb. Cov kev siv technology ntawm lub txheej txheem polarizing tau muab faib ua ob kab ntawm dyeing thiab iodine raws li txoj kev dyeing. Raws li txoj kev ncab, nws muaj peev xwm muab faib ua ob kab: kev ncab qhuav thiab ntub kev ncab. Cov tswv yim thiab kev ua haujlwm yuav raug hloov. Kev kho ntawm polarization, transmittance, hue thiab optical durability.
TAC txheej: Lub thawv polarizing ua los ntawm PVA zaj duab xis yog yooj yim rau nqus dej, ploj thiab poob polarization. Yog li, nws yog ib qho tsim nyog siv ib txheej ntawm TAC (cellulose triacetate) zaj duab xis nrog zoo kho qhov muag tsis zoo thiab daim ntawv pov rau cais tawm ntawm ya raws thiab cua ntawm ob sab. Tiv thaiv cov txheej hauv qab. Ib qho anti-ultraviolet polarizer thiab ib qho tshuaj tiv thaiv polarizer tau tsim tau los ntawm kev siv TAC cov yeeb yaj kiab uas muaj ultraviolet (UV CUT) thiab ib qho kev siv tshuaj tiv thaiv kab mob.
Adhesive: Nws muaj peev xwm muab faib ua ib zaj duab xis sab nplaum thiab ib zaj duab xis sab sab. Kev ua haujlwm ntawm cov zaj duab xis sab sab yog ua kom sib tw cov yeeb yaj duab rau TAC zaj duab xis, thiab cov txheej txheem yuav tsum tsis txhob rov thim rov qab. Lub tsho ua kom tawv nqaij ua daim nplaum yog ib qho laminated rhiab nplaum, uas txiav txim siab txog kev ua haujlwm nplaum thiab cov cuab yeej ua haujlwm ntawm cov polarizer, thiab nws qhov kev ua haujlwm yog ib qho teeb meem feem ntau rau tus neeg siv ntawm lcd polarizer.
Cov duab cais: ib qho tsiaj (ethylene terephthalate) film coated nrog silicon txheej ntawm ib sab, tsuas yog los tiv thaiv lub siab tawv-rhiab sab txheej, thiab lub zog qws tawm yog tib yam rau lub iPad thaj. Cov haujlwm ua haujlwm tau muaj qee yam.
Cov yeeb yaj kiab: A PE (polyethylene) film coated nrog EVA txheej (ethylene vinyl acetate copolymer) ntawm ib sab, uas muaj ib qho uas tsis muaj viscosity thiab ua haujlwm los tiv thaiv qhov TAC zaj duab xis.
Reflective film: Ib zaj duab xis TSWV uas yog ib qho kev sib tw nkaus xwb. Tam sim no, ib qho kev ua yeeb yam tsis txhim kho txhuas yog siv feem ntau. Yog hais tias cov yeeb yam pauv hloov nrog ib zaj duab xis transflective, ib lub hlauv ntshauv tuaj yeem tsim tau. Tsis tas li ntawd, ntau yam kub plating, nyiaj plating zaj duab xis, thiab laser zaj duab xis yuav siv tau los ua cov yeeb yaj kiab los ntawm ntau yam xim tom qab thiab cov tsom iav. Thiaj xav thiab lwm yam teebmeem.
Kev ua yeeb yam loj ntawm lcd polarizer
1. Kev nqus cua axis uas muaj nyob Yog muaj ob hom polarizers rau LCD muag. Yog hais tias lub ncov qab zib tuaj rau ntawm qhov chaw tsim khoom lag luam hauv LCD, tshwj xeeb yog qhov yuav tsum khij los yog piav qhia.
2, Transmittance Transmittance Transmittance indicators were tau muab faib ua ib leeg (ib leeg), mus tib seem (Parallel), ncaj (Crossed) peb yam khoom. Nws feem ntau yog ntsuas raws li JIS-Z-8701 siv tus qauv spectrophotometer ua ke. Lub monomer transmittance hais txog kev xa mus thiab kev hloov mus rau qhov sib luag ntawm qhov kev sib pauv xwb.
