LCD TVs yog lub TV tshaj plaws uas muaj rau cov neeg siv khoom niaj hnub no, thiab, nrog kev tuag ntawm cov ntshav, feem ntau xav tias LCD (LED / LCD) TVs yog tib hom sab laug. Txawm li cas los xij, qhov ntawd tsis yog qhov tseeb vim tias lwm hom TV muaj nyob uas muaj qee qhov txiaj ntsig ntawm LCD - OLED.
Dab tsi OLED TV yog
OLED sawv cev rau Organic Light Emitting Diode. OLED yog qhov kev loj hlob ntawm LCD thev naus laus zis uas siv cov organic sib txuas ua rau hauv pixels los tsim cov duab, tsis tas yuav muaj teeb pom kev zoo ntxiv. Raws li qhov tshwm sim, OLED thev naus laus zis tso cai rau cov ntxaij vab tshaus nyias nyias uas nyias nyias dua li cov tshuaj LCD thiab cov plasma.
OLED tseem hu ua Organic Electro-Luminescence.
OLED Versus LCD
OLED zoo ib yam li LCD hauv qhov OLED vaj huam sib luag tuaj yeem muab tso rau hauv cov txheej nyias nyias, ua kom nyias lub TV thav duab tsim thiab siv lub zog siv hluav taws xob. Tsis tas li ntawd, ib yam li LCD, OLED raug rau cov teeb meem pixel tuag.
Ntawm qhov tod tes, txawm hais tias OLED TVs tuaj yeem tso saib cov duab zoo nkauj heev thiab ib qho tsis muaj zog ntawm OLED piv rau LCD yog lub teeb pom kev zoo. Los ntawm kev tswj hwm lub teeb pom kev zoo, LCD TVs tuaj yeem tsim kom muaj teeb pom kev ntau dua 30% ntau dua li qhov ci ntsa iab OLED TVs. Qhov no txhais tau hais tias LCD TVs ua tau zoo dua hauv qhov chaw ci ntsa iab, thaum OLED TVs zoo dua rau qhov chaw dimly-teeb lossis lub teeb-tswj chav tsev ib puag ncig.
kab hauv qab
OLED zoo ib yam li cov ntshav hauv cov pixels yog tus kheej tawm. Tsis tas li ntawd, ib yam li ntshav plasma, cov qib dub tob tuaj yeem tsim tau. Txawm li cas los xij, zoo li ntshav ntshav, OLED yuav raug hlawv-hauv.
OLED Versus LCD thiab Plasma
Kuj, raws li nws sawv tam sim no, OLED cov lus pom muaj lub neej luv dua li LCD lossis plasma zaub, nrog rau xiav ntawm cov xim spectrum feem ntau txaus ntshai. Tsis tas li ntawd, nqis mus rau nitty-gritty, loj screen OLED TVs yog tus nqi siab dua piv rau LCD lossis plasma TVs.
Ntawm qhov tod tes, OLED TVs tso saib cov duab zoo tshaj plaws uas pom tau tam sim no. Xim yog qhov zoo tshaj plaws thiab, txij li cov pixels tuaj yeem qhib thiab tawm ntawm tus kheej, OLED yog tib lub TV thev naus laus zis uas muaj peev xwm ua kom pom tseeb dub. Tsis tas li ntawd, txij li OLED TV panels tuaj yeem ua kom nyias nyias, lawv tuaj yeem ua rau khoov - ua rau cov tsos ntawm cov duab nkhaus TVs (Ceeb toom: Qee lub LCD TVs tau ua nrog cov ntxaij vab tshaus zoo ib yam).
LG Versus Samsung
OLED thev naus laus zis tuaj yeem siv tau ntau txoj hauv kev rau TVs. Thaum pib, muaj ob qho uas tau siv. LG qhov kev hloov pauv ntawm OLED thev naus laus zis yog hu ua WRGB, uas ua ke nrog cov xim dawb OLED nws tus kheej-emitting subpixels nrog Liab, Ntsuab, thiab xiav xim lim. Ntawm qhov tod tes, Samsung ntiav Liab, Ntsuab, thiab Xiav sub-pixels uas tsis muaj cov lim dej ntxiv. LG txoj hauv kev yog npaj los txwv cov txiaj ntsig ntawm qhov ntxov ntxov Blue xim degradation uas muaj nyob rau hauv Samsung txoj kev.
Nws yog qhov nthuav qhia tias, hauv 2015, Samsung tau tso tawm ntawm OLED TV lag luam. Ntawm qhov tod tes, txawm hais tias Samsung tam sim no tsis ua OLED TVs, nws tau tsim qee qhov tsis meej pem hauv kev lag luam nrog nws siv lo lus "QLED" hauv kev sau npe ntawm qee qhov ntawm nws cov TV siab kawg.
Txawm li cas los xij, QLED TVs tsis yog OLED TVs. Lawv yog cov LED / LCD TVs uas tso ib txheej ntawm Quantum Dots (uas yog qhov "Q" los ntawm), nruab nrab ntawm LED backlight thiab LCD txheej los txhim kho xim kev ua haujlwm. TVs uas siv quantum dots tseem xav tau lub teeb dub lossis ntug teeb (tsis zoo li OLED TVs) thiab muaj ob qho zoo (cov duab ci) thiab qhov tsis zoo (tsis tuaj yeem tso saib dub kiag) ntawm LCD TV technology.
Samsung tab tom tab tom tsim cov TVs uas ua ke Quantum Dots nrog OLED, hu ua QD-OLED. Yog tias ua tiav, lawv tuaj yeem tawm tsam LG hauv OLED TV lag luam.
Resolution, 3D, thiab HDR
Ib yam li LCD TVs, OLED TV thev naus laus zis yog kev daws teeb meem tsis txaus ntseeg. Hauv lwm lo lus, qhov kev daws teeb meem ntawm LCD lossis OLED TV nyob ntawm tus naj npawb ntawm pixels nteg tawm ntawm lub vaj huam sib luag nto. Txawm hais tias tag nrho OLED TVs tam sim no muaj kev txhawb nqa 4K zaub daws teeb meem, qee qhov yav dhau los OLED TV qauv tau tsim nrog 1080p default daws teeb meem zaub qhia.
Txawm hais tias cov neeg tsim TV tsis muaj kev xaiv 3D saib rau Asmeskas cov neeg siv khoom, OLED thev naus laus zis tau sib xws nrog 3D, thiab, txog rau xyoo 2017, LG tau muab 3D OLED TVs uas tau txais zoo heev. Yog tias koj yog tus kiv cua 3D, koj tseem tuaj yeem nrhiav tau ib qho siv lossis tshem tawm.
Tsis tas li, OLED TV thev naus laus zis yog HDR tau tshaj - txawm hais tias HDR-enabled OLED TVs tsis tuaj yeem tso saib qhov ci ntsa iab ntau dua uas ntau lub LCD TV muaj peev xwm - tsawg kawg rau tam sim no.
Txoj kab hauv qab
Tom qab xyoo dhau los ntawm qhov tsis tseeb pib, txij li xyoo 2014, OLED TV tau muaj rau cov neeg siv khoom ua lwm txoj rau LED / LCD TVs. Txawm li cas los xij, txawm hais tias tus nqi yuav nqis los, OLED TVs nyob rau tib lub vijtsam loj thiab cov yam ntxwv tau teeb tsa raws li nws qhov kev sib tw LED / LCD TV yog kim dua, qee zaum ob zaug ntau dua. Txawm li cas los xij, yog tias koj muaj nyiaj ntsuab thiab chav tswj teeb pom kev zoo, OLED TVs muab kev pom TV zoo heev.
Tsis tas li, rau cov uas tseem yog cov kiv cua plasma TVs, so kom paub tseeb tias OLED yog ntau tshaj qhov kev xaiv haum haum.
