Xaiv lub TV zoo yuav nyuaj. LED thiab LCD ob leeg muaj cov yam ntxwv zoo, tab sis qhov twg yog qhov zoo dua? Hauv kab lus no, peb yuav tshawb txog qhov sib txawv tseem ceeb ntawm LED TVs thiab LCD TVs. Koj yuav kawm txog lawv cov kev ua tau zoo, kev siv hluav taws xob, thiab cov duab zoo, pab koj txiav txim siab paub.
LED vs LCD: Qhov txawv yog dab tsi?
Basic Technology Tom qab LCD thiab LED TVs
Txhawm rau nkag siab qhov sib txawv ntawm LED thiab LCD, nws yog ib qho tseem ceeb uas yuav tau pib nrog cov hauv paus.
LCD TVs (Liquid Crystal Display) : LCD TVs siv cov kua siv lead ua kua uas thaiv lub teeb los tsim cov duab. Cov ntxaij vab tshaus no cia siab rau lub teeb pom kev zoo, feem ntau yog cov teeb ci cathode fluorescent (CCFLs), uas ci lub teeb los ntawm cov kua siv lead ua kua los tsim cov duab koj pom ntawm lub vijtsam.
LED TVs (Lub Teeb Emitting Diode) : LED TVs yog ib hom LCD TV, tab sis lawv siv LED backlighting es tsis txhob CCFLs. Qhov sib txawv tseem ceeb no ua rau kev txhim kho qhov ci ntsa iab, xim raug, thiab lub zog ua haujlwm.
Qhov txawv tseem ceeb hauv Display Technology
Qhov sib txawv tseem ceeb ntawm LED thiab LCD thev naus laus zis yog nyob rau hauv hom backlighting siv. Thaum LCD TVs cia siab rau CCFLs, uas loj dua thiab tsis tshua muaj zog-npaum, LED TVs siv me dua, muaj txiaj ntsig lub teeb-emitting diodes. Qhov kev hloov pauv hauv thev naus laus zis no tso cai rau LED TVs kom ua tiav qhov zoo sib xws, ci ntsa iab, thiab tag nrho cov duab zoo. LED TVs muaj peev xwm muab cov duab ntse dua, nrog cov xim dawb dua thiab tob dua. Hauv qhov sib piv, cov ntxaij vab tshaus LCD feem ntau tawm tsam kom pom cov xim dub sib sib zog nqus, tshwj xeeb tshaj yog nyob rau hauv qhov tsaus ntuj, vim tias lub teeb pom kev zoo sib xws nyob thoob plaws lub vijtsam, ua rau nws nyuaj rau kev ua tiav qhov sib txawv.

Daim duab zoo: Lub tshuab twg muab cov kev pom zoo tshaj plaws?
Thaum nws los txog rau cov duab zoo, LED TVs muaj qhov zoo dua ntawm lawv cov LCD counterparts. LED TVs siv lub tshuab dimming hauv zos, tso cai rau thaj chaw sib txawv ntawm lub vijtsam kom muaj qhov sib txawv ntawm qhov ci. Qhov no ua rau cov xim dub tob dua thiab cov xim tiag tiag, tshwj xeeb tshaj yog nyob rau hauv qhov tsaus ntuj. Hauv qhov sib piv, LCDs muaj ib lub teeb rov qab uas ua rau pom tag nrho lub vijtsam zoo ib yam, uas tuaj yeem ua rau cov cheeb tsam dub tshwm greyish thiab txo qhov sib piv tag nrho. Tsis tas li ntawd, LED TVs tau zoo dua ntawm kev tswj qhov ci thiab xim raug thaum saib los ntawm ntau lub ces kaum, thaum LCDs yuav poob duab zoo thaum saib ntawm sab, tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm qhov ci thiab qhov sib txawv.
Xim raug thiab saib lub kaum sab xis
LED TVs kuj zoo dua nyob rau hauv cov nqe lus ntawm cov xim raug thiab saib cov ces kaum. LED backlighting system tso cai rau ntau yam xim kom pom, ua rau daim duab zoo dua thiab muaj tseeb. Tsis tas li ntawd, LED TVs yuav tswj xyuas cov duab zoo dua los ntawm qhov chaw saib cov ces kaum, uas yog qhov tseem ceeb yog tias koj saib TV los ntawm ntau qhov chaw ntawm chav tsev. Hauv kev sib piv, LCD TVs tuaj yeem muaj xim distortion thiab brightness poob thaum saib los ntawm lub kaum sab xis. Qhov no ua rau LED TVs yog qhov kev xaiv zoo dua rau cov neeg uas saib xyuas qhov tseeb ntawm cov xim thiab qhov pom dav, tshwj xeeb tshaj yog nyob rau hauv qhov loj lossis ntau qhov chaw saib tau yooj yim.
Kev ua tau zoo tshaj plaws nyob rau hauv ntau yam kev pom
LED TVs ua tau zoo nyob rau hauv qhov chaw ci ntsa iab vim lawv qhov ci ntsa iab ntau dua. Txawm hais tias koj tab tom saib hauv chav tsev uas muaj teeb pom kev zoo lossis chav tsev uas muaj hnub ci, LED TVs tuaj yeem tswj lub teeb pom kev zoo yam tsis tau poob cov duab zoo. Ntawm qhov tod tes, LCD TVs yuav tawm tsam hauv cov xwm txheej zoo li no, nrog qhov sib piv qis dua thiab cov xim tshwm sim ntxuav tawm. LCDs yuav ua tau zoo dua nyob rau hauv kev tswj teeb pom kev zoo ib puag ncig, xws li dimly lit chav, qhov twg lawv qhov kev ua tau zoo tsis cuam tshuam los ntawm lwm lub teeb pom kev zoo. Yog li ntawd, yog tias koj muaj chav ci ntsa iab, LED TV yuav zoo li muaj kev pom zoo dua.
