Ngati simunagule TV yatsopano kwa nthawi yayitali, pali ma acronyms aukadaulo apa TV omwe mungaphunzirepo. Ena mwa mawu ndi mawu awa – monga HD, 4K, ndi LED – mwina mumawadziwa kale, koma ukadaulo wapa TV wasintha pang’ono pazaka zingapo zapitazi, kutisiyira ma moniker atsopano monga OLED, QD-OLED, ndi Cholinga cha wofotokozera lero, QLED.
Kodi QLED TV ndi chiyani kwenikweni? Chabwino, zitha kukhala zinthu zambiri, popeza wopanga TV aliyense amabweretsa luntha lodziwika bwino patebulo. Yankho lalifupi, komabe, ndilakuti QLED ndi TV ya LED-LCD yokhala ndi madontho ochulukirapo opangidwa mkati. Mukayatsidwa ndi kuyatsa kwa LED, madontho amtundu amatha kugwiritsidwa ntchito kuwongolera milingo yapamwamba ya QLED yowala ndi mitundu. Ndipo ndiko kungokanda pamwamba.
Pazotsatira zonse za bukhuli, tikhala tikuwunika zaukadaulo wa QLED ndikukambirananso ma TV abwino kwambiri a QLED omwe mungagule lero.
QLED ndi chiyani?
QLED ndi ukadaulo wapagulu lowonetsera lachidule la “quantum dot LED.” Teknoloji ya Quantum dot idalengezedwa koyamba ndi Sony kudzera mu mgwirizano ndi QD Vision, koma Samsung idabweretsa mtundu wake pamsika ndipo pakadali pano ili ndi chizindikiro cha QLED, ikugwira ntchito ndi opanga osiyanasiyana apadera kuti ayike mapanelo. Zowonetsa zoyamba za ogula za QLED zidayamba kuwonekera zaka zingapo zapitazo. Tsopano luso lamakono ndilofala komanso lotsika mtengo – ngati mungayang’ane ma TV abwino kwambiri omwe alipo lero, ambiri a iwo ndi QLED.
Kodi QLED imachita chiyani? Imathetsa vuto lomwe ma TV achikhalidwe a LED akhala akulimbana nalo kwa zaka zambiri. Kuti sefa yamtundu wa TV ipange mitundu yowoneka bwino komanso yolondola, ikuyenera kuyamba ndi gwero loyera kwambiri, lodzaza ndi kuwala koyera. Koma mumawongolera bwanji kulondola kwamtundu ngakhale zowunikira zabwino kwambiri za LED zimatulutsa kuwala komwe sikuli koyera bwino?
QLED imathetsa vutoli powonjezera madontho ochulukirapo kuwunikira yakumbuyo ya TV ya TV (motero Q mu QLED). Madontho ochulukirawa ndi timiyala tating’onoting’ono ta phosphorescent tokhala ndi mtundu wamatsenga: Akayatsidwa ndi kuwala, amatulutsa kuwala kwawoko mwachangu kwambiri. Kuwala komwe amatulutsa kumatha kusinthidwa kumagulu enaake amitundu.
Chifukwa chake ma TV a QLED amasinthiratu ma LED oyera a ma LED abuluu ndikuyika madontho ofiira ndi obiriwira pamwamba. Madontho a quantum amatenga kuwala kwa buluu kuchokera ku ma LED ndikusintha kukhala kuwala kofiira ndi kobiriwira. Kuwala kwa buluu kochokera ku ma LED kukaphatikizana ndi kuwala kofiyira ndi kobiriwira komwe kumachokera kumadontho a quantum, mumapeza kuwala koyera koyera. Izi zimapereka fyuluta yamtundu poyambira yomwe ikufunika, ndipo chifukwa chakuchita bwino kwa madontho a quantum, pafupifupi palibe kuwala komwe kumatayika panthawiyi.
Izi zimapereka TV ya LED kuti iwonetse mitundu yambiri molondola kwambiri komanso (ngati kuwala kwa LED kuli ndi mphamvu zokwanira) kuwala kodabwitsa. Izi zimapindulitsa zinthu zamtundu wa dynamic range (SDR), koma ndizothandiza kwambiri mukamawonetsa makanema apamwamba kwambiri (HDR), omwe amadalira kuwala ndi kusiyanitsa kwakukulu.
Ndiye imapezeka pa ma TV a Samsung okha?
Ayi. Samsung idathandizira kutchuka kwaukadaulo wamadontho, ndipo idakhazikitsa chizindikiro cha QLED, koma opanga ma TV ambiri ali ndi mitundu ya TV yotengera madontho masiku ano. Samsung inakhazikitsa Mgwirizano wa QLED mogwirizana ndi Hisense ndi TCL pofuna kulimbikitsa nthawi ya QLED kwa ogula TV, koma mpaka pano, makampani atatuwa amakhalabe okhawo omwe amagwiritsa ntchito malonda awo.
Makampani ena amagwiritsa ntchito mawu awoawo. Vizio amawonjezera mawu oti quantum kumitundu yomwe imagwiritsa ntchito madontho a quantum, mwachitsanzo Vizio P-Series Quantum, pomwe Sony ndi LG ali ndi chizolowezi chopewa mawuwa ngakhale akugwiritsa ntchito madontho ambiri mu ma TV awo a LED.
Ndani amapanga ma TV abwino kwambiri a QLED?
Tili ndi mndandanda wathunthu wa ma QLED omwe timakonda a 2024. Izi zimapangidwa ndi makampani monga Samsung, Sony, Hisense, ndi TCL – mndandanda wa opanga TV omwe onse amabweretsa china chapadera ku teknoloji ya QLED. Pakalipano, chisankho chathu chapamwamba cha QLED cha 2024 ndi Sony Bravia 9 Series yopambana.
Seti yapaderayi imapanga chithunzi chowoneka bwino kwambiri chokhala ndi zowunikira zazikulu za HDR komanso makina osunthika apamwamba kwambiri, zomwe zimapangitsa Bravia 9 kukhala chisankho chabwino kwambiri kwa okonda makanema apakanema komanso okonda masewera apakanema. Palibe kuzungulira pamtengo wokwera pa Sony iyi, pomwe, ndipamene mayina ngati Hisense ndi TCL amalowa m’khola.
Ma QLED monga Hisense U8N Series ndi TCL’s QM8 Series ndi ma TV apamwamba opangidwa ndi mitundu yokonda bajeti. Chifukwa chake, ngakhale chithunzicho sichingakhale chodzaza mwatsatanetsatane ngati cha Bravia 9, mudzasangalalabe ndi kuwala kwabwino, mitundu, ndi kusiyanitsa, komanso kuthekera kowoneka bwino komwe kamakhala pamitundu ina.
Kodi QLED ndiyabwino kuposa OLED?
Ndizosiyana kwambiri ndi matekinoloje owonetsera, kotero kufananitsa pakati pa ziwirizi ndizovuta pang’ono. Kuti mutsike mozama, tikukupemphani kuti muwone nkhani yathu ya QLED motsutsana ndi OLED.
Kuti mumve mwachangu, nayi momwe imagwirira ntchito: OLED imayimira diode yotulutsa kuwala kwachilengedwe. Mawonekedwe amtunduwu amalowa m’malo mwa mapangidwe akale a LED okhala ndi ma pixel opyapyala omwe amatha kupanga kuwala kwawo ndi mitundu yawoyawo ngati pakufunika popanda kudalira kuunikira komwe mapanelo a LED amagwiritsa ntchito.
Mapanelo a OLED ndi ang’ono ndipo amapereka mitundu yowoneka bwino, milingo yosiyana kwambiri ndi zakuda zakuya mozungulira, ndipo palibe vuto lotulutsa magazi. Ngati mumakonda kusiyanitsa, mwina ndiye kusankha kwanu bwino pa TV. Komabe, OLED ilinso ndi zotsika poyerekeza ndi QLED. Ngakhale mitengo yatsika, ikadali ukadaulo wokwera mtengo poyerekeza ndi njira zina. OLED imathanso kulimbana ndi kusungidwa kwa zithunzi / kuwotcha kutengera momwe TV imagwiritsidwira ntchito komanso kukhala ndi malire obadwa nawo ikafika pakuwala.
Kodi QLED imagwira ntchito ndi 4K?
QLED ikupita patsogolo momwe kuyatsa kwa LED ndi kusefa kwamitundu kumagwirira ntchito, pomwe 4K (UHD) imatsimikiziridwa ndi kuchuluka kwa ma pixel pagawo. Mwakutero, ukadaulo wa QLED utha kugwiritsidwa ntchito pa 4K, 8K, kapena malingaliro ena aliwonse omwe amabwera.
Kodi ma TV a QLED ndi okwera mtengo bwanji?
Ma TV a QLED amabwera pamitengo yambiri. Pakali pano ndi okwera mtengo kuposa ma TV amtundu wa LED ndipo ndi otsika mtengo kuposa ma OLED TV. Mukayang’ana mndandanda wathu wamitundu yabwino kwambiri ya QLED, muwona kuti imatha kuyambira $4,000 pamtundu wapamwamba wa 8K mpaka $700 pamtundu wa 4K.
Kodi QLED ndiyabwino pamasewera?
Chifukwa QLED imawonjezera mitundu ndi kuwala, imatha kupanga mitundu yonse yamasewera kukhala yosangalatsa, ngakhale mutakhazikika pamalingaliro ocheperako. Mungafune kusewera ndi zoikamo ndi mitundu yosiyanasiyana, komabe – si aliyense amene amaganiza kuti mitundu yamasewera ndi yabwinoko pa QLED TV.
Ngati mukuganiza za QLED motsutsana ndi OLED pa TV yamasewera, ndi funso lovuta. OLED ndiyabwino kwambiri chifukwa imapereka mitundu yabwino komanso kusiyanitsa – koyenera kusangalala ndi malo amasewera – komanso mitengo yotsitsimula kwambiri, yomwe ndiyabwino pamaudindo ochitapo kanthu mwachangu. Komabe, ma TV amasewera ali pachiwopsezo chosiyidwa pazenera lomwelo kwa nthawi yayitali, zomwe zitha kukulitsa chiwopsezo cha OLED chowotcha. QLED ilibe vuto lomwelo.
Kodi Neo QLED ndi chiyani?
Iyi ndi mtundu watsopano, wapamwamba kwambiri wa QLED womwe Samsung ikupereka. Imalowa m’malo mwamtundu wachikhalidwe wa LED ndi njira yowunikiranso ya mini-LED. Timakambirana za mini-LED mozama m’nkhani ina, koma kwenikweni, ndi gulu la ma LED ang’onoang’ono omwe amatha kupereka zowunikira zolondola kwambiri kuti chithunzithunzi chikhale bwino.
Ma TV ngati Sony Bravia 9 Series ndi TCL QM8 amagwiritsa ntchito zowunikira zapamwamba kwambiri za mini-LED kuti apereke chithunzi chowala komanso chowoneka bwino chosiyana kwambiri.
