Dab tsi yog OLED thev naus laus zis siv hauv TV

QLED o Quantum Dot Teeb-Emitting Diodes nws yog ib qho ntawm ntau cov thev naus laus zis tam sim no hauv TV niaj hnub no uas ncav cuag 4K daws teeb meem lossis siab dua.

Txawm hais tias nrov zuj zus, lo lus tseem ua rau muaj lus nug. Nkag siab tias QLED yog dab tsi nws txoj haujlwm thiab qhov sib txawv tseem ceeb ntawm kev hwm rau lwm yam thev naus laus zis xws li Neo QLED, QNED thiab cov yam ntxwv zoo li cas los saib xyuas thaum xaiv lub TV tshiab.

QLED technology yog dab tsi?

QLED tuaj yeem pom raws li kev txhim kho ntawm LCD. Cov quantum dots siv hauv thev naus laus zis yog cov muaju nanometers hauv txoj kab uas hla uas tawm qhov ntev ntawm lub teeb. Cov nanocrystals no yog tsim los ntawm cov khoom siv semiconducting uas muab cov nyhuv quantum confinement, uas tshwm sim thaum electrons hauv cov khoom raug kaw rau qhov ntim me me.

Quantum confinement tso cai rau nanocrystals muaj peev xwm hloov kho thiab kho lub wavelength ntawm lub teeb raws li lawv qhov loj me, tsim cov xim sib txawv yam tsis tas yuav tsum muaj cov tshuaj sib xyaw ua ke.

Txawm hais tias quantum dot thev naus laus zis tau txais nws thawj daim ntawv thov kev lag luam hauv xyoo 2013, hauv cov khoom siv xws li Sony Triluminos, kev tshawb fawb ntawm quantum confinement tau ua txij li xyoo 1982, thaum cov kws tshawb fawb Lavxias tau txheeb xyuas qhov tshwm sim.

Hauv cov khoom siv nrog QLED thev naus laus zis, muaj cov qauv tsim los ntawm LCD npo, zaj duab xis ntawm quantum dots thiab backlight ua los ntawm LEDs uas tawm lub teeb xiav.

Lub teeb nraub qaum yog cov teeb ua los ntawm lub teeb thiab lwm yam khoom uas muab lub teeb tsim nyog rau cov txheej txheem tsim cov duab ntawm cov ntxaij vab tshaus uas tsis tsim lawv lub teeb. LCD TVs feem ntau siv lub teeb rov qab dawb, thaum QLED thev naus laus zis siv lub teeb xiav LED.

Cov nanocrystals tam sim no nyob rau hauv QLED li yog ib qho ntawm qhov sib txawv ntawm cov thev naus laus zis, txij li hauv zaj duab xis muaj cov crystals tshwj xeeb uas tsim cov xim liab, ntsuab thiab xiav. Qhov kev ua haujlwm no tiv thaiv cov tonal variations, ua purer, ntau tiag tiag xim thiab brighter zaub.

Puas yog QLED twb yog tus qauv lossis tseem muaj TVs qis dua?

Txawm hais tias tau txais koob meej, QLED TVs qhia qhov chaw nrog lawv cov laus LCD thiab LED cov kwv tij. Cov thev naus laus zis no siv lub teeb pom kev zoo thiab muaj cov yam ntxwv zoo sib xws, txawm hais tias QLED qauv ci dua thiab muaj qhov dav xim gamut.

Ntxiv rau cov qauv no, muaj cov xov tooj cua nrog OLED thev naus laus zis, uas tsim cov duab los ntawm lwm txoj hauv kev uas ua rau cov duab sib txawv. Yog li ntawd, nws yog qhov nyuaj me ntsis los txheeb xyuas qhov zoo ntawm cov cuab yeej, raws li kev siv thev naus laus zis nkaus xwb.

Hauv kev sib piv yooj yim dua, peb tuaj yeem hais tias QLED cov ntxaij vab tshaus nthuav tawm qhov ci ntsa iab ntau dua thiab cov xim zoo nkauj dua, thaum OLED cov ntxaij vab tshaus muab cov xim dub tob dua thiab qhov sib txawv dua, vim lawv tus kheej illuminated organic diode thev naus laus zis uas tso cai rau txhua qhov qhib lossis tawm. tus kheej.

Vim tias QLED thiab LED TV qauv xav tau lub teeb ci los tsim cov duab, lawv muaj kev tswj lub teeb tsawg dua li OLED qauv, ua rau greyer, tsis muaj kev ncaj ncees dub.

Ntawm qhov tod tes, QLED TVs tuaj yeem muab ntau yam xim, ci ntsa iab ntau dua thiab zoo li yuav muaj teeb meem tsawg dua nrog kev xav ntawm lub vijtsam, ib yam dab tsi uas tuaj yeem ua rau lawv qhov kev xaiv zoo rau qhov chaw ci dua.

Qhov tseem ceeb tshaj plaws ntawm lub sijhawm yuav khoom yog kom paub txog cov chaw tsim khoom, tus nqi ntau thiab cov kev qhia tshwj xeeb ntawm cov qauv tshuaj ntsuam xyuas, suav nrog qhov koj cov peev nyiaj tso cai rau koj them.

Lub zog ntawm QLED TVs

  • brighter cov ntxaij vab tshaus;
  • Ntau ntau xim;
  • Tus nqi pheej yig dua piv rau OLED TVs;
  • Kev txuag hluav taws xob ntau dua piv rau cov qauv LED.

Tsis muaj zog ntawm QLED TVs

  • Cov qib dub qis dua OLED qauv; dub tuaj yeem dim;
  • Kev pom cov kaum qis dua OLED qauv;
  • Lub sij hawm teb siab dua li OLED qauv.

Puas yog Crystal UHD txawv ntawm QLED?

UHD iav yog ib lo lus siv los ntawm Samsung los txhais nws cov qauv LCD TV yooj yim tshaj plaws uas siv LED backlighting thiab ua tiav cov kev daws teeb meem txog 3840 x 2160.

Cov khoom siv txhais tau tias yog Crystal UHD feem ntau pheej yig dua QLED TVs vim tias lawv muaj cov qauv me me thiab ncav cuag qhov kev daws teeb meem siab tshaj plaws txog li 4K. Tsis zoo li QLED qauv, uas siv quantum dots thiab tuaj yeem ua tiav cov kev daws teeb meem ntawm 4K thiab 8K, nyob ntawm tus qauv.

Cov kev qhia tshwj xeeb ntawm Crystal UHD TVs:

  • Refresh tus nqi mus txog 60 Hz;
  • 4K yog qhov siab tshaj plaws daws teeb meem tiav;
  • Lawv tsis muaj HDMI 2.1 input.

Dab tsi yog qhov txawv ntawm Neo QLED?

Neo QLED yog ib qho kev txhim kho ntawm QLED thev naus laus zis, siv los ntawm Samsung hauv nws cov khoom siv pib txij xyoo 2021.

Qhov sib txawv tseem ceeb uas Neo QLED nthuav tawm yog kev siv MiniLEDs, uas vim lawv qhov me me, tuaj yeem ua pawg ntau dua hauv cov cheeb tsam dimming, uas txhais tau rau hauv kev tswj lub teeb ntau dua, zoo dua qhov sib piv thiab cov kaum sab xis.

QNED puas yog tib yam?

Dab tsi yog OLED thev naus laus zis siv hauv TV

Ntxiv nrog rau cov tswv yim kev lag luam kom muaj lub npe txawv (tab sis tsis yog li ntawd), LG's QNED siv Nanocell technology, tsim los ntawm lub tuam txhab los nthuav qhia cov xim ncaj ncees thiab saib cov ces kaum zoo dua.

QLED puas ua rau hlawv?

Yog lawm. Hauv QLED TV phau ntawv qhia, muaj cov lus qhia kom tsis txhob tso cov khoom siv nrog cov duab zoo li qub rau lub sijhawm ntev los tiv thaiv kev kub hnyiab. Txawm li cas los xij, qhov teeb meem no cuam tshuam ntau dua rau OLED TVs.

Puas yog QLED zoo rau kev ua si?

Yog lawm. Txawm hais tias OLED TVs muaj lub sijhawm teb qeeb, muaj cov kev xaiv zoo hauv QLED qeb. Thaum xaiv ib lub TV rau kev ua si, nco ntsoov tias lub cuab yeej muaj lub sijhawm teb tsawg thiab lub siab ua kom rov zoo dua, nyiam dua ntaus 120Hz.
