Qhov Tseem Ceeb Qhov txawv - Samsung 4K SUHD vs UHD TV
Qhov sib txawv tseem ceeb ntawm Samsung 4K SUHD thiab UHD TV yog tias Samsung 4K SUHD siv Quantum Dot Technology thaum Samsung 4K UHD siv LCD / LED Technology. Samsung 4K SUHD thiab UHD TVs tau dhau los ua cov neeg sib tw tseem ceeb nrog OLED TVs hauv ntiaj teb niaj hnub no. Samsung 4K SUHD thiab UHD muaj cov yam ntxwv tshwj xeeb uas yog qhov tseem ceeb hauv kev ua lag luam TV niaj hnub no, raws li cov tuam txhab ua lag luam tau tshaj tawm cov thev naus laus zis tshiab los ua kom tau raws li cov kev xav tau ntawm cov neeg siv khoom. Cia wb mus saib ob tus qauv saum toj no kom pom tias lawv yuav zoo npaum li cas hauv ntiaj teb kev sib tw niaj hnub no.
Samsung 4K SUHD Review
Samsung tau paub tias tsim cov khoom zoo tshaj plaws 4K SUHD TVs txij li hnub cov hom TV no tau los rau hauv. Zoo dua li yav dhau los, tam sim no Samsung's 4K SUHD TV txhawb nqa Ultra-High Definition.
Nyob rau yav dhau los, kev lag luam hauv TV yog txhua yam hais txog leej twg tuaj yeem ua qhov loj tshaj plaws ntawm tus nqi tsim nyog. Txawm li cas los xij, tam sim no cov ntxhuav tau tig; TV manufacturers tam sim no sib ntaus sib tua rau nanometers. Quantum dot technology yog ib lo lus buzz nyob rau hauv lub ntiaj teb kev lom zem niaj hnub no, thiab qhov no yog qhov uas SUHD tuaj. los yog LED zaub. Qhov tsuas yog downside yog qhov sib piv yuav tsis zoo li ntawm OLED.
Lub 4K SUHD JS8500 series TV tsis muaj tag nrho array LED, tab sis kim dua JS9500 series TV muaj. Cov ntug-lit LEDs muab cov duab zoo thiab ci ntsa iab. Lub vijtsam yog txheej txheej zoo nrog cov duab sib txawv molecular uas tsim cov duab tiag tiag, ci ntsa iab, saturated thiab vibrant duab. Kev siv Quantum dot thev naus laus zis ua rau SUHDs sib tw nrog cov qauv siab dua li OLED.
Cov nanocrystal semiconductors (2-10nm) yog lub hauv paus ntawm cov puzzle thaum nws los txog rau Quantum Dot thev naus laus zis. Cov no yog cov ntsiab lus uas tso tawm qhov tseeb wavelength kom rov tsim cov xim ntau dua ntawm cov zaub. Cov nanocrystals no tau nyob ib puag ncig ntev, tab sis tam sim no tsuas yog tam sim no cov thev naus laus zis tau ua rau hauv tsev. Cov hom kev qhia no ua rau kom cov xim raug nce mus txog 30% nrog rau cov xim gradation nce 64 quav hauv txhua pixel tib lub sijhawm.
Lwm qhov tseem ceeb ntawm cov zaub no yog qhov kev hloov xim yog ob zaug nrawm dua hauv SUHD npo piv nrog UHD zaub. Hauv lwm lo lus, qhov ntxoov ntxoo ntawm ntau cov xim tuaj yeem tsim tau raug nrog kev siv tshuab no. Lwm qhov zoo tshaj plaws muaj nrog 4K SUHD TVs yog qhov qhib OS tsim los ntawm Tizen. Qhov no tuaj yeem ua ke nrog 5 Samsung li siv lub zog qis Bluetooth muaj nyob nrog lub TV. Cov yam ntxwv ntxiv muaj xws li ua si lub tswb teeb ntawm lub xov tooj hauv TV. Kuj tseem muaj tus pab cuam tus kheej uas pab cov ntu tshiab muaj.
Cov qauv no tuaj nrog lub tshuab ua kom muaj zog uas hloov txhua yam SD lossis Full HD cov ntsiab lus kom saib zoo nkauj dua. Cov yam ntxwv no tsuas yog thib ob rau Sony hauv kev ua lag luam.
Samsung 4K UHD TV Review
Lub 4K Ultra High-definition (UHD) TV tau dhau los ua cov khoom siv tau zoo yav dhau los. Feem ntau, UHD TV muaj li ntawm 4 npaug ntawm pixel daws teeb meem ntawm cov pa HD TV. Muaj ntau ntau qhov screen rau xaiv, thiab cov nqi tau dhau los pheej yig dua. Qhov zoo tshaj plaws yog tias 4K cov ntsiab lus muaj rau UHD TV, uas muab cov TVs 'kev daws teeb meem zoo dua li HDTV. Muaj ntau 4K TVs uas sib tw rau qhov chaw ua lag luam. Lub thev naus laus zis tshiab Ultra HD Blu-duab tshav tsuas yog nyob ib ncig ntawm lub ces kaum uas muab 4K UHD TVs kom zoo dua lwm tus qauv.
Technology giants xws li LG, Samsung, Panasonic, thiab Sony yog nyob rau hauv tus txheej txheem ntawm kev ntes ib tug ntau dua kev ua lag luam nyob rau hauv TV technology. Cov hom TVs nrog 4K no yog cov npe nrov tshaj plaws hauv kev ua lag luam. Yog tias peb yuav tsum ua tib zoo saib ntawm 4K UHD TV, nws yog qhov tseeb LCD TV uas tuaj yeem tsim cov kev daws teeb meem siab dua li cov LCD. UHD TVs muaj kev daws teeb meem ntawm 3840 X 2160 pixels lossis 82944000 pixels. Qhov no tuaj yeem raug hu ua 4K nce qib lossis 4 zaug HD daws teeb meem. Cov lus qhia ntawm 4K UHD tsim cov xim raug tab sis, zoo li hauv ntau lub LCDs thiab LEDs, qhov kev nplua nuj tsis zoo li SUHD TVs. SUHD yog qhov zoo dua hauv kev muab cov ntaub ntawv nplua nuj, qhov tseeb thiab qhov pom tob dua li 4K UHD.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm 4K UHD TV yog nws lub peev xwm los nce qib HD video mus txog plaub zaug nws qhov kev daws teeb meem. Cov teeb liab HD tau txais los ntawm TV tsis suav nrog siv hauv vaj huam sib luag daws teeb meem thev naus laus zis. Qhov kev daws teeb meem siab dua no ua rau cov duab zoo dua thiab muab qhov kev paub peb-dimensional ntau dua li qhov kev ua tau zoo ntawm ob sab. Nrog rau kev txhim kho nyob rau hauv kev daws teeb meem, lub sharpness ntawm cov duab thiab clarity kuj tau nce. Nrog rau tag nrho cov kev txhim kho no, daim duab zoo kuj tseem txhim kho kom muab cov duab zoo nkauj.
Lwm qhov tshwj xeeb ntawm 4K UHD TVs yog qhov ci ntsa iab thiab lub siab tshaj plaws lub teeb pom kev zoo. Ob qhov ci ntsa iab thiab lub ncov dawb lub teeb tso zis tau txhim kho nrog kev hloov pauv ntawm LED thev naus laus zis. Cov TVs no kuj suav hais tias yuav kav ntev dua OLED TVs.
