Qhia cov ntsiab cai
LED cov lus qhia, ib hom zaub raws li semiconductor lub teeb - emitting DIODE thev naus laus zis, muaj ntau me ntsis LED hlaws dai. Cov hlaws dai liab, ntsuab, thiab lub teeb xiav, uas, los ntawm kev sib xyaw ua kom haum, tuaj yeem tso saib cov duab muaj xim zoo nkauj thiab muaj xim zoo nkauj. Nyob rau hauv cov cawv tam sim no, electrons thiab qhov nyob rau hauv LED nti decombine, tso lub zog hauv daim ntawv ntawm photons, yog li emitting teeb. Ua tsaug rau nws lub teeb ywj siab {}}} emnitive ceev, LED qhia cov duab zoo nkauj tab sis kuj tuaj yeem hloov cov kab lus tam sim no, kev sib tham cov kev xav tau.
Ua kua Crystal qhia tawm (LCDs) txiav txim siab seb lub teeb hla mus los ntawm kev tswj hwm kev ua kua siv lead ua kua crystal molecules. Lawv tsuas yog muaj cov vaj huam sib luag ua kua Crystal, lub backlight, thiab polarizers. Cov kua ua kua crystal molecules lawv tus kheej tsis emit teeb; Hloov chaw, lawv cia siab rau lub teeb tawm los ntawm lub backlight rau cov zaub. Raws li lub teeb kis los ntawm vaj huam sib luag ua kua Crystal, kho cov lej ntawm cov ua kua crystal molecules hloov lub teeb polarization, yog li ua tiav kev tswj hwm lub teeb pom kev zoo. Tom qab, tom qab ua los ntawm cov lim xim lim, cov kab lcd tuaj yeem tso cov duab nplua nuj thiab muaj xim zoo nkauj. Piv rau cov lus coj ua kom ntxaws, lcd cov lus qhia ntxaws ntxaws thiab ntau dua xim ncaj ncees, tab sis lawv cov txiaj ntsig zoo nkauj thiab nrawm yog qis dua qis dua.
Tso saib ua yeeb yam
Piv txwv sib piv: LED cov ntaub ntawv muaj lub txiaj ntsig tseem ceeb hauv kev sib piv. Vim tias lawv cov leds tuaj yeem hloov tag nrho, lawv tsis tawm ntawm lub teeb thaum ua kom pom xim dub, muab cov duab nplua nuj, muab cov xim nplua nuj thiab cov tawv nqaij dub thiab dawb. LCD cov lus qhia, ntawm qhov tod tes, tsuas tuaj yeem hloov pauv ua kua lead ua kua crystal molecules los thaiv lub teeb, ua rau qee qhov kev xau siab, ua rau muaj kev sib txawv qis dua.
Pom lub kaum sab xis: LED qhia tau muaj qhov pom lub ntsej muag dav, ua rau muaj kev hloov pauv tsawg, ua kom muaj ntau yam kev hloov pauv ntawm cov ntsiab lus sib txawv, muab cov neeg saib cov ntsiab lus meej. LCD cov lus qhia muaj qhov sib luag ntawm lub kaum ntse ntse, tshwj xeeb tshaj yog nyob rau thaum ntxov txo tau tshwm sim thaum pom los ntawm tawm- center kaum. Txawm hais tias kev nce qib thev naus laus zis tau txhim kho qhov pom ntawm LCD cov lus qhia, nws tseem ntog luv luv ntawm LED cov lus qhia.
Cov xim ua tau zoo: LED cov lus tuaj yeem tso tawm cov xim tsis muaj zog heev thiab cov xim nplua nuj, nrog cov xim ntau, ua rau cov duab zoo li qub thiab lub neej. LCD cov lus kom zoo nyob rau hauv cov xim yug me nyuam, qhov tseeb reproducing cov xim qub ntawm cov duab ntawm cov duab, tab sis lawv cov kab mob siab yuav yog qis dua me ntsis rau cov coj. Txawm li cas los xij, rau cov kws tshaj lij kev xav tau cov xim uas xav tau, xws li yees duab thiab tsim qauv, lcd qhia kev xaiv nyob rau qhov kev xaiv zoo.
Chaw thov
LED cov lus qhia, vim lawv lub siab ci ntsa iab, qaug zog, kav ntev, ua si ib qho chaw tshaj tawm sab nraud, chaw ntau pua chaw, thiab tsheb thauj mus los tsheb thauj. Piv txwv li, LED qhia txog cov ntawv sab nraum zoov loj sab nraum zoov kom pom meej meej txawm tias muaj zog lub hnub, muaj kev nyiam cov xim ntawm passersby. Sab hauv chaw saib pob zeb, lawv muab cov neeg saib xyuas nrog cov duab ntshiab thiab ntxaws ntxaws kos thiab tiag- lub sij hawm cov qhab nia hloov tshiab. Thaum lub sij hawm ua yeeb yam, LED qhia ntxiv cov lus thov pom dua ntawm cov yeeb yam nrog lawv cov duab muaj kuab lom thiab muaj kev cuam tshuam zoo.
Hauv kev sib piv, LCD cov lus qhia tau zoo rau cov chaw ib puag ncig hauv tsev, xws li chav tsev hauv tsev, chav saib xyuas computer, thiab cov chav qhia khoos phis tawm. Lawv cov duab zaub yog qhov muag muag heev thiab kev ua haujlwm xim yog siab, ua rau saib cov yeeb yaj kiab txhua hnub xws li kev saib cov yeeb yaj kiab thiab TV series, lossis ua duab kos. Tsis tas li ntawd, LCD cov lus qhia tsawg dua lub zog thiab tsim kom muaj cua sov tsawg dua, ua rau lawv muaj zog dua ib puag ncig thiab lub zog}}}} siv.
Nqi thiab Nqe
Cov nqi yuav khoom: Hauv qab qhov loj me thiab daws teeb meem, tus nqi yuav ntawm cov zaub coj yog feem ntau siab dua li ntawm LCD zaub. Qhov no yog feem ntau vim yog LED zaub tsim cov txheej txheem, xav tau ntau ntau ntawm cov chips thiab txhawb nqa cov neeg tsav tsheb cirips. Tsis tas li ntawd, kev nqis peev hauv kev tshawb fawb technology thiab cov khoom siv khoom lag luam thiab cov khoom siv ntau lawm yog tus loj. Hauv kev sib piv, LCD cov kev tsim thev naus laus zis yog cov paub tab ntau dua, nrog kev lag luam saw ua tiav, ua rau muaj tus nqi qis.
Cov nqi ua haujlwm: LED qhia muaj kev siv zog siab, tshwj xeeb tshaj yog nyob rau qib siab zoo, uas siv zog ua haujlwm nce siab. Tsis tas li ntawd, txawm hais tias LED cov lus qhia muaj lub neej ntev, puas tsuaj rau cov khoom siv coj ib tug neeg tuaj yeem cuam tshuam rau tag nrho cov kev cuam tshuam, nce nqi kho. Hauv kev sib piv, LCD cov lus qhia muaj zog qis dua, thiab yooj yim dua los kho, ua rau cov nqi qis.
Hauv cov ntsiab lus, LED thiab LCD cov lus sib txawv txawv hauv cov hauv paus ntsiab lus, qhia cov teebmeem, kev thov cov xwm txheej, thiab cov nqi. Cov neeg siv yuav tsum xav txog lawv tus kheej cov kev xav tau thiab kev siv cov xwm txheej thaum ua kev xaiv. Rau sab nraum zoov los yog loj- teev cov ntawv thov uas xav tau cov duab ci siab, dav saib pom kev zoo, LED cov lus qhia zoo tshaj plaws. Txawm li cas los xij, rau cov ntawv thov sab hauv tsev uas cov duab nthuav dav, thiab tus nqi thiab siv hluav taws xob yog qhov tseem ceeb dua, lcd cov lus qhia tau ntau dua. Nrog rau kev nce qib nruam ntawm kev siv thev naus laus zis, ob kab no cov cuab yeej thev naus laus zis yuav txuas ntxiv ua kom muaj txiaj ntsig thiab ua kom zoo dua, coj cov neeg siv ntau dua zoo dua.
