Kev nthuav dav ntawm LCD LCD polarizer thiab nws txoj kev siv technology

Aug 11, 2017

Muaj pes tsawg leeg ntawm lub ncov

Thawj polarizer feem ntau muaj cov duab PVA uas muaj lub teeb nyob rau hauv nruab nrab, thiab tom qab ntawd ces TAV tiv thaiv yeeb yaj kiab yog muab sau rau ob sab. Thiaj li yuav ua kom yooj yim thiab siv cov teeb meem kho qhov sib txawv, cov khoom siv roj hmab yuav tsum muaj cov tshuab LCD, thiab ob sab yog coated nrog lub siab tawv, ua npog los ntawm cov yeeb yaj kiab, lub polarizer yog tus tshaj plaws TN kev sib kis. Yog hais tias koj tshem tawm ib txheej ntawm tso tawm zaj duab xis, thiab tom qab ntawd txheej txheej ntawm zaj yeeb yaj kiab, yog qhov tseem ceeb tshaj plaws ua kom tau polarizer. Siv cov nplaum siab-ntxhib nplaum hluav taws kub heev uas muaj cov kab mob siab tawv tiv thaiv ua kua, qhov PVA tshwj xeeb dipping kev kho mob (qoob series), polarizing zaj duab xis ua rau ntau hom kev kub ntxhov; ntxiv tiv thaiv ultraviolet tivthaiv nyob rau hauv siab-rhiab nplaum siv, yuav ua los ntawm anti anti ultraviolet polarizing zaj duab xis yog compounded ntawm lub birefringence; optical compensation film nyob rau hauv thawj zaj duab xis kis, tau ua los ntawm STN polarizer; nyob rau hauv thawj zaj duab xis kis tau thiab compound lub teeb mus rau zaj duab xis, tuaj yeem ntawm cov dav hlau polarizer los yog nqaim kaum polarizer; lub siab rhiab siab, PVA zaj duab xis los yog TAC zaj duab xis uas siv rau xim, xim xim ncov qaum. Nyob rau hauv qhov tseeb, nrog rau kev loj hlob ntawm cov khoom tshiab LCD, hom polarizer yog ntau thiab ntau dua. Lub hom phiaj tseem ceeb yog ua kom cov Polaroid polarizing zaj duab xis ob lub nruab nrab ntawm qhov nruab nrab lub teeb ntawm polarization, yog ib qho tseem ceeb ntawm kev siv cov duab LCD ua luminous. Kev siv lub tshuab ua polarizer tam sim no, feem ntau yog siv cov roj cawv (PVA) ua cov substrate, nrog txhua hom dyeing nrog ob hom tshuaj dyes rau xim, thiab txuas rau hauv ib qho chaw txias thiab cov av qeeg, kom nqus ob dichroic dye forming polarization properties, tsim ntawm thawj zaj duab xis polarizer nyob rau hauv tshem tawm ntawm dej, tom qab ziab. Vim tias lub tshuab PVA muaj ib co qauv hydrophilic, lub cev nqaij daim tawv ntawm kev tiv thaiv cov duab tho polarizing, polarizing zaj duab xis ntawm ob tog kom lub txheej txheej muaj lub siab hloov lub cev, dej dej tsis zoo thiab txhua yam muaj zog ntawm peb cellulose acetate (TAC) zaj duab xis rau kev tiv thaiv, uas tsim thawj phaj polarizer. Nyob rau hauv lub TN hom LCD polarizing zaj duab xis ntau lawm, raws li kev cai sib txawv, yuav tsum muaj cov tawv nqaij-rhiab nplaum ntawm ib sab ntawm lub thawv polarizer coated nrog ib co thickness, thiab lub composite ntawm siab-rhiab nplaum hluav taws kev tiv thaiv film; thiab rau sab nraud raws li hom khoom, raws li, kev tiv thaiv cov yeeb yaj kiab, cov yeeb yaj duab sib luag, cov pob tshab ntxig ntxig, uas yog tsim cov khoom ua kom cov khoom ua paj yeeb. STN hom LCD polarizer khoom, tab sis kuj yog nyob rau hauv qhov siab-rhiab nplaum txheej ntawm ib sab, raws li qhov xav tau ntawm cov neeg siv khoom, raws li ib lub zeem muag ntawm cov nyiaj raug them muaj qhov txawv ntawm qhov sib txawv ntawm cov theem ntawm zaj duab xis thiab kev tiv thaiv zaj duab xis, thiab txoj kev ua tus STN hom polarizer LCD cov khoom, qhov no yog qhov yooj yim thiab kev ua haujlwm ntawm cov qauv hauv polarizer.


Cov yam ntxwv ntawm polarizing PVA zaj duab xis

PVA yog ib zaj duab xis polarizing tau siv cov txujci kom ntev rau cov khoom, muaj qee cov cim tshwj xeeb: xim lub teeb: los ntawm txoj kev coj polarization thiab qhov kev taw qhia ntxiv ntawm lub teeb kis dhau; kub thiab humidity rhiab heev: kev ya raws lossis ua kom sov, ncab rau hauv txoj kab saw hlau yuav cia li tig rov qab rau cov khoom qub tuaj rau pawg. Poob teeb ntsig txog. Fragility: nws yog ib qho yooj yim kom poob lub teeb xim xaiv nyob rau hauv sab nraud rog. Kev cais tawm ntawm Polarizer: raws li qhov ntsuas kub tau muab faib ua hom zoo li ntxaiv, dav hom kub lub cev; los ntawm kev sib kis tus nqi muab faib ua cov duab zoo tib yam, cov yeeb yaj duab siab sib kis; Raws li keeb kwm yav tas los faib ua gray xws li polarizer, colour polarizer; Cov khoom siv kho qhov muag uas muaj kev sib txawv nyias muaj nyias qhov kev sib kis, ib nrab kis tau tus kheej, ib nrab ntawm lub zog, tag nrho cov kev xav, kho qhov muag thiab lub hauv paus tswj.

1. Lub ntsiab ntawm cov nyhuv ntawm qhov kev ua tau zoo: kev ua kom tuab; kev xa tawm (kev xa tawm, kev sib pauv mus los, kev sib kis ntsug); polarizing efficiency; kev tswj xim (NBS); xim membrane hom; UV tsis kam

2. Polaroid cog sim txoj kev thiab qhov kev txiav txim siab: qhov loj: A, txoj kev sim: siv tus pas ntsuas, micrometer los yog caliper ntsuas polarizer thawj zaj duab xis ntev, dav thiab thickness. B: Cov txheej txheem: cov txiaj ntsim kev ntsuas tau tsim nyog hauv qhov kev ntsuas ntau yam los ntawm lub chaw muag khoom. Photoelectric kev ua tau zoo: A, kev ntsuam xyuas: lub qauv ncov qis rau qhov khoom, thiab nrog tib hom polarizer tam sim no siv los kuaj tib yam khoom, piv rau nws qhov kev ua tau zoo. B, Txuj Kauj Vam: kev ntsuam xyuas tus qauv Voff tus nqi thiab kev tsim Voff tus nqi yog sib npaug; kev ntsuam xyuas tus qauv zoo tshaj qhov ntau tshaj qhov khoom sib txawv; kuaj cov qauv tom qab xim thiab cov kev cai ntawm tus qub keeb kwm. Kev ntseeg: A, txoj kev sim: lub ncov qaum teb yuav tsum tau muab tso rau hauv lub iav, thiab tso siab nrog cov khoom zoo li cov khoom siv coj los kuaj, piv rau nws cov kev ntseeg tau zoo. B thiab qhov ntsuas: tom qab kev ntsuam xyuas kev ntseeg siab, kev kho qhov muag thiab hluav taws xob thiab kev cia siab ntawm cov kev ntsuam xyuas tau zoo ib yam li cov uas muaj tib lub qauv coj, thiab tsis pub dhau ntawm cov khoom kuaj cov qauv. Muab tshuaj thiab ua kom zoo li cas: A, sim txujci: yuav tsum tau ntsuas cov ncov qaum ncov qaum rau cov iav, rov txuas dua, ncuav ntau dua ib zaug. B txuj: nws muaj peev xwm rov qab, coated thiab stripped ntau tshaj peb zaug. Tom qab peb zaug, tsis muaj cov kua nplaum residual sab laug ntawm lub khob. Tom qab lo, nws yog khov kho nrog tus npaus. Lub npaus yog tag nrho muab tshem tawm raws li qhov tsis teem los ntawm qhuav, thiab nws yog sim los ntawm kev kub thiab high humidity.

3. Cov cai tswj kev xaiv polarizer: A + cov khoom ua haujlwm thaj ua rau thaj, hauv txojcai, xaiv qhov tseem fais fab tuag tag nrho tus qauv, muaj qee yam khoom siv tau TFT tsis muaj daim duab peb tog khoom; nyob rau hauv tus cai, xaiv thawj lub Hoobkas tseem tag nrho. Ib qho khoom txheem, feem ntau yog siv daim ntawv teev cov qauv ntawm daim ntawv qib siab, Cov ntaub ntawv seem hauv daim duab peb sab, lossis ntau yam khoom ntawm TFT seem polarizer; los yog tom qab TFT yog lub ntsiab channel ntawm Polaroid seem muag khoom, thawj theem ntawm tag nrho cov zaj duab xis tag nrho los yog Polaroid zaj duab xis. B cov khoom siv tshuaj Qib, raws li siv tau tsawg dua ntawm cov khoom muag, TFT seem, polarizer, nti, los sis tom qab tsis yog tus muag khoom ntawm kev tsim khoom ntawm TFT thiab cov khoom ntawm Polaroid zaj duab xis, tsis zoo cais tsis zoo. Thaum cov qhua muaj cov kev cai tshwj xeeb, tus tshwj xeeb polarizer yuav tsum raug xaiv raws li tus neeg yuav tsum tau ua.

4. Siv tshuab siv: lub teeb kov, tsis tuaj yeem siv cov khoom nyuab ntawm qhov chaw ntawm kab. Tsis txhob quav thaum noj lossis tso. Rau qib thiab cov duab kos, xim sib cais yuav tsum muab coj los ua ntej lawv muab tso rau hauv ntau lawm. Ib qho chaw, nco ntsoov tawm qhov chaw ntawm lub tshuab ntxuav hluav taws xob tsis so ntswg tag nrho, huv si, thiab mam li tso rau lub ncov. Thaum lub ultra wide polarizer txiav, cov kua nplaum yuav tsum muab tso rau hauv lub ntsej muag.
