Tus polarizer yog qhov tseem ceeb ntawm LCD zaub. Nrog kev tawm tsam tag nrho cov kev ua haujlwm ntawm Lamination, Polerizers tau dhau los ua ntau dua cov hauv LCD panels.
Lub npe tag nrho ntawm polarizer yogNcauj Zaj Duab XisCov. Nws tau txais nws lub npe vim tias txheej ntawm zaj duab xis ntsib tus saib nyob rau hauv ib txwm muaj kev cuam tshuam thiab scarter lub teeb, yog li kev txhim kho saib cov ces kaum.
COLARIER yog dab tsi?
Los ntawm lub cev tsis muaj lub cev, lcd cov lus qhia cia siab rau polarized teeb kom tsim cov duab. Txhua LCD muaj ob daim duab thaij duab - ib qho ntawm sab xub ntiag thiab ib sab nraub qaum - nruj nreem rau lub khob substrate. Ua ke, lawv tsim ua kua crystal txheej nrog tag nrho cov tuab ntawm ib ncig ntawm 1 hli. Yog tias tus polarizer yog ploj lawm, LCD tsis tuaj yeem tso tawm cov duab. Yog li ntawd, polarizers yog qhov tseem ceeb hauv LCD zaub kev tsim khoom.
Hauv kev lag luam LCD, polarizers tau siv dav. Lawv txoj haujlwm tseem ceeb yog ua haujlwm nrog cov kua muaj kua los tsim cov duab pom. Thaum tsim khoom, ob nplooj ntawv ntawm tempered iav yog luam tawm nrog circuittry, ntim nrog cov nplaum raws cov npoo, thiab nias ua ke. Ua kua siv lead ua kua tau txhaj ntawm lawv thiab tom qab ntawd kaw. Tus polarizer yog tom qab ntawd thov rau sab saum toj thiab hauv qab ntawm lub khob sib dhos.
Cov qauv ntawm tus polarizer
Tus polarizer muaj ntau txheej, feem ntau suav nrog cov yeeb yaj kiab tiv thaiv, TAC lossis PC (triacetate lossis polycarbonate), thiab PVA (polyvinyl cawv):
Tiv thaiv zaj duab xis: Cov duab thaiv cov polarizer nto. Nws yuav tsum tau muab tshem tawm ua ntej zaum kawg cov khoom sib dhos.
TAC lossis PC: Txhawb nqa thiab tiv thaiv txheej PVA los ntawm kev tawg, shrinking, lossis cuam tshuam los ntawm kev noo noo, thiab yuav muab cov txheej txheem kev kho mob saum npoo av.
Pva txheej: Cov khoom siv tseem ceeb uas yog cov teeb liab.
Muaj nuj nqi ntawm tus polarizer hauv LCD cov lus qhia
Cov polarizer tswj cov kev taw qhia ntawm lub teeb ci. Lub teeb ntuj tsis muaj nuj nqis. Raws li nws tau dhau ntawm tus lej polarizer, lub teeb vauv rau qhov kis tau mus rau kis tus kab mob axis tau nqus, tso cai tsuas yog thaum sib kis kom dhau los. Qhov kev xaiv lim no ua rau lub teeb sib txawv thiab thaum kawg ua cov duab pom ntawm lub vijtsam.
Cov polarizers
Hloov Kho Polarizer:
Tso cai rau tag nrho cov kev tso cai ntawm Backlight, nthuav dav dawb thiab ua kom cov duab ntshiab.
Qhov zoo tshaj plaws rau cov lus qhia uas kev noj hluav taws xob tsis yog kev txhawj xeeb loj.
Reflective Polarizer:
Tsis pub Backlight mus dhau tab sis qhia txog cov teeb pom kev zoo los ua cov duab pom.
Zoo tshaj plaws rau cov chaw sab nraum zoov uas muaj kev tshav ntuj txaus thiab kev siv hluav taws xob tsawg tsawg.
Hloov pauv Polarizer:
Ua ke sib txuas ob qho tib si kev sib txuas thiab kev cuam tshuam lub peev xwm.
Tso cai rau backlight kom dhau mus thaum tseem pom cov teeb pom kev zoo, muab cov versatility rau ntau yam teeb pom kev zoo.
