Qhov Tseem Ceeb Qhov txawv - OLED vs 4K LED TV
Qhov sib txawv tseem ceeb ntawm OLED thiab 4K LED TV yog tias OLED TV zaub muaj ib tus kheej teeb LEDs thaum lub 4K LED los nrog backlit LED vaj huam sib luag. Cia peb ua tib zoo saib ntawm qhov sib txawv no thiab los xaus rau qhov twg TV muaj lub siab tawv.
OLED TV yog dab tsi?
Cov OLED TVs suav nrog nws tus kheej lub teeb Organic LEDs uas ci ntsa iab rau cov zaub ntau dua li lub vaj huam sib luag LCD. Yog tias peb yuav txhais OLED, nws txhais tau tias Organic Light Emitting Diode. Txhua pixel yog ci ib tus zuj zus, uas yog qhov tseem ceeb ntawm cov zaub.
Xim Kev Ua Haujlwm
Cov xim hloov pauv tuaj yeem piv nrog cov TV LED zoo tshaj plaws hauv khw. Cov xim no tau txhim kho qhov tseeb thiab zoo nrog lub sijhawm dhau mus. Txawm hais tias cov xim tau txhim kho, kev nplua nuj thiab saturation ntawm cov xim tau coj lub rooj zaum rov qab, uas yog qhov poob siab me ntsis.
Resolution
Qhov kev daws teeb meem txhawb nqa los ntawm OLED TVs tsuas yog 1920X1080 (tus qauv txhais)
Clarity
Cov duab yuav ntse thiab nthuav dav, ua tsaug rau OLEDs hauv TVs. Raws li elaborated ua ntej, cov zaub muaj peev xwm tsim tau tiag tiag, nplua nuj xim thiab sib sib zog nqus dub nrog rau ntxoov grey tib lub sij hawm.
Deep Blacks / Contrast
Vim qhov tseeb tias kev siv thev naus laus zis zoo li lub vijtsam plasma, cov pixels ntawm OLED tau teeb ib los ntawm ib qho muab txoj hauv kev rau cov xim dub nrog rau qhov sib txawv zoo dua. Hais txog cov xim dub thiab qhov sib txawv, qhov no yog cov cuab yeej zoo tshaj plaws uas muaj nyob rau tam sim no.
Brightness
Nrog rau kev hloov pauv ntawm LED thev naus laus zis, LEDs tau ci dua nrog txhua tus qauv ntawm 4K LED TVs. Raws li OLED TVs 'pixel tau teeb ib tus zuj zus, qhov ci yuav tsis tuaj yeem sib npaug 4K LED TVs.
Uniformity
Lub OLED TVs tuaj yeem tsim cov duab nrog qhov sib txawv uas sib npaug sib npaug ntawm daim duab. Qhov no feem ntau yog ua tau vim ib tus neeg pixels tau teeb hla lub vijtsam. Qhov no nyob rau hauv lem txhim kho cov duab zoo ib yam nkaus.
Side Angle View
Raws li nrog plasma TVs, lub kaum sab xis saib ntawm OLED TVs yog qhov tshwj xeeb. Qhov no yog vim tus kheej lit pixels thiab qhov sib xws ntawm qhov screen, uas tsis muaj nrog backlit LED panels.
Lub neej
Lub OLED TVs yog cov thev naus laus zis tshiab, yog li nws tsis paub meej tias lawv yuav kav ntev npaum li cas. Cov plasma TVs muaj qee qhov teeb meem thaum lawv tau qhia, xws li kub hnyiab ntawm cov zaub. Tsuas yog lub sijhawm yuav daws tau tias cov qauv no yuav kav ntev npaum li cas.
4K LED TV yog dab tsi?
4K UHD TV's yog qhov tseeb LCD TVs uas tuaj yeem tsim cov duab daws teeb meem zoo dua li LCD TV li niaj zaus. Nws yog qhov tsim nyog yuav raug hu ua 4K LCD TV hauv lwm lo lus. 4K TVs suav nrog Ultra High Definition, uas txhawb kev daws teeb meem ntawm 3840X2160 pixels uas yog qhov kev daws teeb meem zoo rau txhua lub TV.
Xim Kev Ua Haujlwm
Lub OLED zaub ua haujlwm hauv kev sib koom tes nrog txhua yam xim, liab, ntsuab thiab xiav. Ib lub pixel yog sawv cev los ntawm tag nrho cov xim no. Cov xim no muaj peev xwm ua haujlwm ua ke thiab tsim tag nrho cov xim ntawm cov xim spectrum uas tuaj yeem ua rau ntau lab. Cov xim tau zoo sawv cev raws li daim duab qub, thiab nws yog qhov tseeb dua li LCD. Cov dluab muaj cov xim zoo nkauj dua qhov tseeb dua uas muab cov duab tso tawm kom pom tseeb dua.
Resolution
Thaj chaw 4K TV tseem hu ua Ultra Siab txhais uas muaj peev xwm ua tau zoo tshaj qhov kev daws teeb meem txog 3840X2160 pixels.4K TVs muaj qhov ua tau zoo los txhim kho lub teeb liab siab txhais rau hauv 4K daws teeb meem nrog kev siv cov thev naus laus zis thev naus laus zis. Cov no ua rau cov duab tuaj yeem pom nyob ze 3D nrog cov ntsiab lus loj tshaj plaws uas tuaj yeem tsim los ntawm TV.
Clarity
Raws li kev siv thev naus laus zis ntau ntxiv, peb tuaj yeem cia siab tias qhov tseeb tsis txaus ntseeg thiab ntse ntawm cov zaub. Thaum lub teeb liab txhais siab hloov mus rau 4K daws teeb meem video, qhov kev daws teeb meem nce 4 zaug. Qhov no yog ib qho tseem ceeb heev vim hais tias haiv neeg 4K cov ntsiab lus tsis tshua muaj nyob rau hauv kev ua lag luam. Cov duab zoo yuav saib zoo nrog kev sib txuas ntawm kev nthuav dav thiab ntse.
Deep Blacks / Contrast
Nyob rau yav dhau los, cov LCD vaj huam sib luag tau pom muaj kev txhim kho tseem ceeb hauv cov kev daws teeb meem. Tab sis muaj cov plasma TVs uas muaj qib dub zoo dua li 4K LED TVs. OLEDs muaj kev daws teeb meem zoo dua li lub plasma TV. Yog li muaj ntau qhov kev ntes tau los ntawm 4K LED TVs hauv cheeb tsam no.
Brightness
Lub 4K LED TVs tuaj yeem tsim cov ntxaij vab tshaus.
Uniformity
Lub vijtsam zaub tsis zoo ib yam vim siv lub teeb rov qab. Qhov no yog ib qho ntawm cov teeb meem tseem ceeb ntawm backlit TVs. Qee zaum cov keeb kwm ci ntsa iab raug tsim tawm, lossis cov qauv zoo li bar tshwm nyob thoob qhov screen. Qhov teeb meem no tuaj yeem txo qis me ntsis los ntawm kev txo qhov teeb tsa backlight.
Side Angle View
Txawm hais tias lub kaum sab xis saib ntawm LED TVs tab tom txhim kho, lawv tseem poob qab ntshav ntshav thiab OLED TVs.
Lub neej
Lub 4K LED TVs tau nyob ib puag ncig rau qee lub sijhawm thiab paub tias kav ntev.
Qhov txawv ntawm OLED TV thiab 4K LED TV yog dab tsi?

Black Level
OLED TV: Nws tuaj yeem tsim cov xim dub tob dua, vim qhov screen tau siv los ntawm ib tus kheej lit pixels.
4K LED TV: Lub vijtsam tsis tuaj yeem tsim cov xim dub zoo li lub vijtsam OLED, vim yog lub teeb pom kev zoo ntawm LED
Brightness
OLED TV: Qhov tsis zoo ntawm lub teeb ci ntawm tus kheej yog tias nws tsis tuaj yeem tso tawm qhov ci siab tshaj plaws
4K LED TV: Raws li LED thev naus laus zis tau hloov zuj zus, cov ntxaij vab tshaus tau ua kom ci dua
Uniformity
OLED TV: Qhov kev sib piv ntawm qhov screen yog sib xws li txhua pixel ntawm lub vijtsam yog lit.
4K LED TV: Vim lub vijtsam rov qab, tom qab yuav ci dua qhov nruab nrab ntawm lub vijtsam uas yuav tsis zoo ib yam.
Side Angle View
OLED TV: OLED muaj peev xwm nthuav tawm lub kaum sab xis zoo
4K LED TV: Daim duab zoo ploj mus vim qhov pom tau txav ntawm qhov chaw mus rau lub kaum sab xis ntawm lub vijtsam.
Summary:
OLED vs 4K LED TV
Nws pom tseeb tias ob leeg muaj lawv tus kheej lub zog piv rau lwm qhov hauv ntau qhov chaw. Daim duab zoo thiab qhov tob tob muab lub OLED sab sauv tes thaum lub 4K LED zoo dua los ntawm qhov kev daws teeb meem ntawm qhov pom thiab cov duab sharpness. Lub kaum sab xis saib ntawm OLED zoo dua li ntawm 4K LED, uas yog backlit. Txawm li cas los xij, qhov kev txiav txim zaum kawg yuav nyob ntawm tus neeg siv nyiam.
