LED Backlit Zaub: Nkag siab txog thev naus laus zis tom qab cov ntxaij vab tshaus niaj hnub
Yog tias koj tau yuav lub TV lossis khoos phis tawj saib tsis ntev los no, tej zaum koj tau ntsib lo lus "LED Backlit." Kev nkag siab txog dab tsi LED backlit zaub txhais tau tias tuaj yeem pab koj txiav txim siab yuav khoom zoo dua. Cov thev naus laus zis no yog lub hauv paus ntawm cov pav ca niaj hnub feem ntau - vaj huam sib luag qhia.
Dab tsi yog LED Backlit Display?
Lub Ntsiab Lus
LED backlit zaub yog lub vijtsam LCD uas siv Lub Teeb Emitting Diodes (LEDs) ua lub teeb ci tom qab cov kua siv lead ua kua. Cov kua nplaum ua kua lawv tus kheej tsis tsim lub teeb-lawv ua raws li lub kaw lus uas tswj xyuas seb lub teeb hla dhau npaum li cas. Cov LEDs muab lub teeb pom kev zoo uas ua rau pom cov duab.
Ntug -Lit vs. Full-Array
Muaj ob lub ntsiab configurations rau backlit LED zaub technology. Ntug- cov teeb pom kev zoo muaj LEDs nyob rau ntawm cov npoo ntawm lub vijtsam, nrog lub teeb qhia vaj huam sib luag faib lub teeb thoob plaws qhov chaw. Tag nrho - cov lus qhia array muaj LEDs nyob ncaj qha tom qab LCD vaj huam sib luag, tso cai rau kev tswj teeb pom kev zoo dua.
Lub luag haujlwm ntawm Local Dimming
Hauv zos dimming yog qhov tshwj xeeb uas thaj chaw tshwj xeeb ntawm LEDs tuaj yeem dim los yog tua ntawm nws tus kheej. Qhov no tso cai rau cov zaub kom ua tiav cov xim dub los ntawm kev txo lub teeb hauv qhov tsaus ntuj ntawm daim duab. Tag nrho -array cov lus qhia feem ntau muaj ntau qhov chaw dimming hauv cheeb tsam tshaj li ntug-lit zaub.
Yuav ua li cas LED Backlighting piv rau Cov Tshuab Laus
Cov duab LCD qub siv CCFL (Cold Cathode Fluorescent Teeb) backlighting. LED backlighting muaj ntau yam zoo:
Zog Efficiency:LED backlight feem ntau siv tsawg zog
Thinner Design:LEDs tso cai rau thinner zaub panels
Zoo Brightness Control:LEDs tuaj yeem dimmed ntau dua
Ntev Lifespan:LEDs feem ntau kav ntev dua CCFL raj
Cov ntawv thov tseem ceeb thiab cov xwm txheej
TV
Feem ntau niaj hnub TVs siv LED backlit zaub technology. Cov kev teeb tsa tshwj xeeb-ntug-lit lossis tag nrho-array- cuam tshuam rau cov duab zoo. Tag nrho -array displays feem ntau nyiam rau kev saib cinematic.
Computer Monitors
LED backlit zaub yog tus qauv hauv computer saib. Cov kws tshaj lij saib xyuas xim - ua haujlwm tseem ceeb tuaj yeem siv tag nrho - teeb pom kev zoo rau cov xim raug zoo dua.
Digital Signage
Cov khoom lag luam rau kev kos npe kuj tseem siv LED backlighting. High- qauv ci ntsa iab muaj rau cov khw muag khoom thiab sab nraum zoov.
Dab tsi los saib rau hauv LED Backlit Zaub
Qhov sib piv piv
Qhov sib piv piv qhia qhov txawv ntawm qhov ci tshaj plaws dawb thiab qhov tsaus ntuj tshaj plaws. Qhia nrog lub zos dimming feem ntau ua tau zoo dua qhov sib piv.
Brightness (Nts)
Brightness yog ntsuas nyob rau hauv nits. Qhov ci ntsa iab siab dua yog feem ntau xav tau rau cov duab hauv qhov chaw ci ntsa iab. Kev siv sab hauv tsev yuav xav tau 200-500 nits, thaum siv sab nraum zoov yuav xav tau 1000+ nits.
Xim raug
Rau cov ntawv thov kev tshaj lij, qhov tseeb xim yog qhov tseem ceeb. Tag nrho -array qhia nrog lub zos dimming feem ntau muab cov xim zoo dua hauv qhov tsaus ntuj.
Qhov zoo ntawm LED Backlit Technology
Txhim kho duab zoo
LED backlighting tso cai rau qhov sib txawv zoo dua, qhov ci dua, thiab cov xim raug dua piv rau cov cuab yeej qub.
Kev txuag hluav taws xob
LED backlighting feem ntau siv hluav taws xob tsawg, uas tuaj yeem txo cov nqi khiav lag luam dhau sijhawm.
Tsim Flexibility
LED thev naus laus zis tso cai rau nyias, sib dua cov duab tsim uas yooj yim rau nruab thiab ua kom zoo nkauj dua.
Cov lus xaus thiab cov lus pom zoo
Kev nkag siab txog dab tsi LED backlit zaub yog pab koj txiav txim siab paub thaum yuav TV, saib, lossis kos npe digital. Rau ntau daim ntawv thov, LED backlighting muab cov duab zoo heev. Rau kev pom qhov tseem ceeb, tag nrho -array nrog lub zos dimming feem ntau muaj kev ua tau zoo dua. Rau kev siv dav dav, ntug-lit zaub muab tus nqi zoo. Xav txog koj qhov chaw saib tshwj xeeb thiab hom ntsiab lus thaum xaiv cov zaub.
Cov lus nug nquag nug (FAQ)
1. Qhov txawv ntawm LED thiab LCD yog dab tsi?
LCD yog hom vaj huam sib luag, thiab "LED" yog hais txog cov teeb pom kev zoo siv los teeb lub vaj huam sib luag. Tag nrho cov lus qhia LED yog LCD, tab sis tsis yog txhua lub LCD qhia siv LED backlight.
2. Lub zos dimming nyob rau hauv ib qho LED backlit zaub yog dab tsi?
Hauv zos dimming tso cai rau thaj chaw tshwj xeeb ntawm LEDs kom dim ntawm nws tus kheej, txhim kho qhov sib piv thiab qib dub.
3. Lub LED backlit zaub kav ntev npaum li cas?
LED backlights feem ntau muaj lub neej ntev, feem ntau ntsuas rau kaum tawm txhiab teev ntawm kev siv.
