Yuav ua li cas xaiv QLED thiab OLED TV
Dec 08, 2021
& quot; Xyoo 2019, tus naj npawb ntawm cov neeg siv xaiv quantum dots yog 2.5 npaug ntawm cov neeg siv OLED, thiab rau cov ntxaij vab tshaus loj tshaj 75 ntiv tes, tus naj npawb ntawm cov neeg siv xaiv quantum dots yog 12 npaug ntawm cov neeg siv OLED."
Tam sim no, cov tshuab TV kub tshaj plaws yog quantum dots. Ntau thiab ntau lub lag luam tau txhawb nqa lawv tus kheej quantum dot TVs, thiab tib lub sijhawm lawv ua tus chij uas quantum dot TVs siv cov cuab yeej zoo tshaj plaws.
Kuv ntseeg tias ntau tus neeg tau txais kev pab yuav tsis muaj lus nug zoo li no thaum ntsib kev tshaj tawm kev lag luam loj: Dab tsi yog quantum dot? Puas yog nws zoo heev?
Thov nyeem nws nrog cov lus nug. Kab lus no yuav qhia koj cov lus zais ntawm Quantum Dot TV.
Txhawm rau nqa daim ntaub thaiv ntawm quantum dot TV, peb yuav tsum xub nkag siab tias quantum dots yog dab tsi.
Hauv layman' cov ntsiab lus, quantum dots (QuantumDots) yog cov nanoparticles me me heev nrog txoj kab uas hla ntawm 2-10 nanometers, feem ntau muaj zinc, cadmium, selenium thiab sulfur atoms. Nws muaj cov yam ntxwv tshwj xeeb ntawm photoelectric: quantum dots ntawm cov kab sib txawv tuaj yeem ua rau lub teeb ci monochromatic ntawm cov xim sib txawv nyob rau hauv lub stimulation ntawm lub teeb los yog hluav taws xob, thiab cov xim yog ntshiab heev. Feem ntau, quantum dot nrog qhov loj ntawm 2 nanometers tuaj yeem ua rau lub teeb ntsuab ntshiab tshaj plaws, lub quantum dot nrog qhov loj ntawm 4 nanometers tuaj yeem ua rau lub teeb xiav ntshiab tshaj plaws, thiab quantum dot nrog qhov loj ntawm 6 nanometers tuaj yeem ua rau lub teeb liab ntshiab tshaj plaws. .
Nws yog qhov tseeb ntawm cov yam ntxwv ntawm quantum dots uas tuaj yeem tso tawm lub teeb ci ntsa iab monochromatic uas tib neeg siv nws los tso saib thev naus laus zis.
Quantum dots tuaj yeem txhawb nqa los ntawm lub teeb lossis hluav taws xob, thiab cov thev naus laus zis tau muab faib ua ob pawg: Active Quantum Dot Light-Emitting Diode (AMQLED) thiab quantum dot backlight technology. Lub qub yog stimulated los ntawm hluav taws xob thiab lub tom kawg yog stimulated los ntawm lub teeb.
Active quantum dot light-emitting diodes yog quantum dots uas tuaj yeem tawm lub teeb tom qab muaj zog. Nws zoo ib yam li OLEDs, tshwj tsis yog tias cov khoom siv hluav taws xob hauv OLED yog hloov nrog cov inorganic quantum dots.
Tab sis vim tias tam sim no AMQLED cov cuab yeej siv tsis tau paub tab txaus thiab cov nqi xav tau, lub npe hu ua quantum dot TVs ntawm lub khw yog cov TV uas siv quantum dot backlight technology, uas yog, kua siv lead ua vaj huam sib luag + quantum dot backlight txheej. . Lawv cov ntsiab lus tseem yog cov kua siv lead ua kua TV (LCD).
Raws li tau hais los saum no, quantum dot TV ntawm lub khw tsuas yog ib hom LCD TV. Dab tsi yog qhov txawv ntawm nws thiab zoo tib yam LCD TV?
Peb paub tias lub teeb ci ntawm LCD TV los ntawm LED backlight tom qab lub vijtsam, thiab cov spectrum ntawm LED teeb tsis txuas ntxiv.
Txhawm rau muab nws yooj yim, nws lub zog yog qhov tseem ceeb hauv cov kab xiav thiab daj, thiab cov kab ntsuab thiab liab tsis muaj zog txaus. Yog li ntawd, qhov kev ua tau zoo ntawm cov xim liab thiab ntsuab ntawm lub LCD TV dav dav tsis zoo, thiab tag nrho cov saib thiab kev xav ntawm daim duab TV tsis zoo, thiab nws cov xim gamut tsuas yog 72%.
Lub quantum dot backlight thev naus laus zis zoo heev rau qhov tsis txaus ntawm LCD TVs.
Lub quantum dot backlight technology yog ntxiv ib txheej ntawm quantum dot zaj duab xis nyob rau hauv pem hauv ntej ntawm LED backlight. Quantum dot zaj duab xis feem ntau muaj peb txheej txheej, feem ntau yog tsim los ntawm quantum dots, optical qib dej thiab oxygen barrier zaj duab xis thiab resin. Quantum dot cov ntaub ntawv yog yooj yim heev rau hydrolyzed thiab oxidized, yog li quantum dot TVs xav tau kev ntim tshuab zoo dua, uas yog ib qho ntawm cov laj thawj rau kev nce nqi ntawm quantum dot TVs.
Raws li tau hais ua ntej, quantum dots tuaj yeem ua rau lub teeb pom kev zoo nrog cov xim purity siab dua nyob rau hauv lub stimulation ntawm lub teeb. Lub teeb ntawm LED backlight yog irradiated ntawm quantum dot zaj duab xis, thiab quantum dot zaj duab xis tau hloov mus rau hauv lub teeb liab siab heev, lub teeb ntsuab thiab lub teeb xiav.
Liab, ntsuab thiab xiav yog peb lub ntsiab xim ntawm lub teeb. Tag nrho cov xim uas peb tuaj yeem pom nrog lub qhov muag liab qab tuaj yeem muab sib xyaw rau hauv ib qho kev faib ua feem. Yog li ntawd, cov xim tau los ntawm kev sib xyaw xim liab, ntsuab thiab xiav nrog cov purity siab heev kuj tseem ci heev, yog li cov thev naus laus zis no tuaj yeem txhim kho xim kev ua tau zoo ntawm LCD TVs. Raws li cov ntaub ntawv pov thawj kev soj ntsuam luam tawm los ntawm National Radio thiab TV Product Quality Supervision and Inspection Center, raws li NTSC tus qauv, cov xim gamut kev pab them nqi ntawm quantum dot TV yog siab li 110%!
Txawm hais tias QLED (quantum dot) thiab OLED yog lub npe zoo sib xws, qhov tseeb, QLED TV yog ib hom LCD TV, uas txawv ntawm OLED heev. Txawm li cas los xij, hauv thaj chaw ntawm high-end TV, nws nyuaj hais tias QLED thiab OLED muaj zog dua. Thaum kawg ntawm tsab xov xwm no, kuv yuav txheeb xyuas lawv los ntawm qhov kev xav ntawm cov xim gamut, ci ntsa iab, tswj lub teeb, lub neej ncua, saib lub kaum ntse ntse, thiab cov lus teb ntawm lub vijtsam.
Xim gamut
Cov xim gamut qhia cov xim ua haujlwm ntawm TV. Qhov siab dua qhov xim gamut, qhov zoo dua cov xim zaub. Cov xim gamut cim los ntawm OLED TVs ntawm kev ua lag luam yog 95%+. Txawm hais tias qhov no yog tus nqi siab heev, OLED TVs tsis ua ntej QLED TVs nrog 110% xim gamut!
qhov kaj
OLED yog tus kheej-luminous technology. Tsis muaj backlight. Cov organic teeb-emitting cov ntaub ntawv ntawm qhov screen yog energized thiab emit lub teeb, ib yam li cov teeb me me. OLED tsis tuaj yeem tso lub teeb ci siab rau lub sijhawm ntev, txwv tsis pub nws yuav cuam tshuam rau lub neej. Lub ntsiab lus ntawm QLED yog LCD TV, thiab ultra-high brightness tuaj yeem yooj yim nce los ntawm kev ua kom lub zog ntawm lub teeb rov qab. Yog li peb tuaj yeem pom tias qee qhov quantum dot TVs txawm tias ncav cuag 4000 nits thaum lub teeb ci ultra-siab tau qhib, thaum lub siab tshaj plaws ntawm OLED TVs feem ntau nyob ib ncig ntawm 800 nits.
Lub teeb tswj
Txij li thaum lub teeb ci ntawm LCD TV los ntawm lub teeb rov qab, cov yeeb yaj kiab polarizing hauv LCD npo thaiv lub teeb thaum pom cov xim dub, tab sis lub teeb rov qab tseem nyob, yog li nws tsis tuaj yeem tso cov xim dub. OLED yog tus kheej-luminous, thiab nws tsuas yog xav tau lub hwj chim tawm ntawm" lub teeb me me" los tso saib dub, yog li OLED zoo dua rau kev tswj lub teeb.
lub neej
Txij li thaum OLED siv cov khoom siv hluav taws xob cov teeb pom kev zoo uas tsis muaj zog dua li inorganic quantum dots nyob rau hauv cov nqe lus ntawm kev pab cuam lub neej, lub neej kev pab cuam ntawm quantum dots muaj peev xwm ncav cuag 60,000 teev, uas yog ob zaug ntawm OLED!
Saib lub kaum sab xis
Cov duab me me yog ib qho teeb meem tshwm sim ntawm LCD TVs, thiab cov duab zoo tso tawm ntawm lub vijtsam LCD yuav txo qis thaum lub kaum sab xis loj dua. Thiab OLED tsis tuaj yeem cuam tshuam qhov zoo thiab hnov ntawm lub siab tshaj plaws ntawm 84 °!
Teb sijhawm
Txhua pixel ntawm OLED tuaj yeem hloov pauv thiab tawm ntawm nws tus kheej, uas yog cov lus teb ceev tshaj plaws ntawm txhua lub TV zaub thev naus laus zis. Yog li ntawd, tus" smearing" Qhov tshwm sim ntawm qhov screen zoo dua li QLED TVs.
Cov ntsiab lus
QLED TVs tam sim no yog cov TV kub tshaj plaws ntawm cov TV siab kawg. Lawv muaj txiaj ntsig zoo nyob rau hauv cov nqe lus ntawm kev pab cuam lub neej, xim kev ua tau zoo, thiab ci ntsa iab, thaum OLED TVs ua tau zoo dua ntawm kev tshuaj ntsuam teb, saib cov ces kaum, thiab kev siv lub zog. Cov phooj ywg uas xav yuav high-end TVs tuaj yeem xa mus rau lawv qhov zoo thiab qhov tsis zoo thiab yuav lawv raws li lawv xav tau!
