Monga tafotokozera m'mawu anga oyamba, ndime za LCD ndizofala kwambiri m'magulu padziko lonse lapansi. Komabe, izo zikunenedwa, ma TV a LCD ali ndi zopinga, zomwe zimaphatikizapo kuyambitsa mitundu ndi ntchito yakuda, makamaka poyerekeza ndi ma TV a Plasma. Kuphatikizidwa kwa ma LED akuda-ndi-kutsogolo- kayendedwe kabwino kwathandiza zedi, koma izo sizinali zokwanira.
Malinga ndi zolephera izi, makampani opanga TV (makamaka LG) akhala akutsata OLED ngati yankho, monga ma TV omwe amagwiritsa ntchito teknoloji ya OLED akhoza kupanga mitundu yonse ya mtundu wa gamut ndi yakuda kwambiri.
Komabe, ngakhale kuti OLED imatchulidwa kuti ndi njira yabwino yowonjezerapo ku LED / LCD, patatha zaka zambiri zowonjezera ndikulephera kuyesa msika, mu 2014 LG ndi Samsung yokha inalowa mumsika wa TV ndi TV zazikulu za OLED TV zomwe zinayambika ku CES 2013 pogwiritsa ntchito ziwiri njira zosiyana.
LG imagwiritsa ntchito njira yomwe imatchedwa WRGB, yomwe imagwiritsidwa ntchito yophatikizapo magetsi oleda OLED ndi ojambula amtundu kuti apange zithunzi, pamene Samsung imaphatikizapo kuwala kofiira, kobiriwira, ndi kofiira komwe kumatulutsa opidipili OLED.
Ma TV OLED amawoneka okongola, koma pali vuto limodzi lomwe likuyimitsa makampani ena onse a TV pobweretsa TV Zosasangalatsa kumsika pamtengo waukulu, mtengo.
Komanso, ziyenera kuwonetseratu kuti Samsung yataya mwayi wogulitsa TV ku OLED mu 2015, kusiya LG ndi, ndipo tsopano Sony, ndizo zokha za ma TV OLED zomwe zimagulitsidwa ku msika wogula.
Ngakhale kuti makanema a LCD ndi ovuta kwambiri kupangidwa kuposa ma TV OLED, zoona zenizeni n'zakuti ma OLED akhala, okwera mtengo, opanga makina akuluakulu owonetsera TV. Izi ndizo chifukwa cha zolakwika zomwe zimawonetsa polojekiti yopanga zomwe zimapangitsa kuchuluka kwa zojambula za OLED kuti zisakanidwe kuchokera ku ntchito zazikulu zazithunzi. Zotsatira zake, zambiri zomwe zimatchulidwa ndi OLED (monga kukwanitsa kuwonetsera mtundu wautali ndi chiwindi chakuda chakuda) pa TV / LCD TV zimatsutsidwa.
Pogwiritsa ntchito mavuto a OLED komanso kupanga nawo ma Dummy Dots mukulumikiza ma TV / LCD TV pakali pano (komanso kusintha kwakukulu kofunikira pa msonkhano), Quantum Dots ikhoza kukhala tikiti yobweretsa ntchito ya TV / LCD TV pafupi ndi omwe TV opanga anali kuyembekezera ndi OLED - komanso mtengo wotsika kwambiri.
LCD ndi Quantum Dots vs OLED
Kuwonetseredwa pa tsamba ili ndi chithunzi choyerekeza ndi kuwala, kuunika, ndi mphamvu zoyenera kugwiritsa ntchito ma TV awiri a LED LED / LCD omwe amaphatikizapo Mavotuku a Zowonjezera ndi obadwa oyamba TV omwe atulutsidwa ndi Samsung ndi LG.
Popanda kufotokozera zambiri, mukamayerekezera maselo onse anayi, mumapeza kuti mtunduwu ukugwirizanitsa ma seti a Sony Quantum Dot - omwe ali ndi LED / LCD omwe amagwiritsidwa ntchito poyerekezera, ndipo ma Samsung Galaxy OLED ali pafupi kwambiri, pamene LG OLED kukhazikitsa kwenikweni kumawoneka kuti sakugwira ntchito.
Komabe, pamene Samsung yatha kukhala ndi kuwala kwapamwamba, onse a Sony Quantum Dot LED / LCD ndi maselo a LG OLED ali pafupi kwambiri.
Komabe, kusiyana kwakukulu kwambiri ndiko kugwiritsa ntchito mphamvu. Monga mukuonera, ma TV onse OLED amadya mphamvu zambiri kuposa Sony yomwe amagwiritsidwa ntchito poyerekeza, makamaka mukapitiriza kuona kuti seti ya Sony 4K ya masentimita 65 imagwiritsira ntchito mphamvu zochepa kuposa TV ya OLED ya 55 inchi. Izi zikutanthawuza, kulepheretsa kulimbitsa zamakono mu mibadwo yotsatira ya OLED TVs, kuti TV ya OLED TV 65 inchi ingadye mphamvu yoposa mphamvu yake yowonjezera / LCD TV yowonjezera.
Chinthu china choyenera kukumbukira ndi chakuti ngakhale ma TV / LCD ma TV amawononga mphamvu pazomwe zimakhala zosaoneka bwino ngakhale kuti zinthu zina pa TV, monga Smart TV, etc ..., zikagwira ntchito zingakhudzire kugwiritsira ntchito mphamvu) , OLED mphamvu yogwiritsira ntchito TV imasintha ndi mlingo wa kuwala kofunika kutulutsa zithunzi. Kotero, kuunika kwowonjezera, mphamvu yowonjezereka - ndipo ndithudi, kugwiritsira ntchito Smart TV ndi zina zidzasintha izi.
Kotero, monga momwe mungathe kuwonetsera monga momwe tawonetsera pa chithunzicho, ndalama zambiri zomwe zimagwiritsidwa ntchito komanso kugula TV yosavuta sizingaperekedwe patsogolo pa TV yowonjezera.
Zolemba Zowonjezera - Zamakono ndi Zamtsogolo
Pali zowonjezera zitatu za Quantum Dot Technology zomwe zingagwiritsidwe ntchito pa ma TV, QD Vision (yomwe imapereka njira yothetsera ma TV / LCD TV), ndi Nanosys ndi 3M (zomwe zimapereka njira ya Quantum Dot film (QDEF) kuti agwiritsidwe ntchito ndi Full Array backlit LED / LCD TV).
Kumanzere kwa chithunzi chomwe chili pamwambapa, TV kumanzere ndi Samsung 4K LED / LCD TV, ndipo mpaka kumunsi ndi pansi ndi LG 4K OLED TV. Pamwamba pa LG OLED TV ndi Philips 4K LED / LCD TV yokhala ndi teknoloji ya Quantum Dot. Monga momwe mukuonera, zowonjezera zimatulutsa zambiri pa Philips kuposa momwe Samsung imaikidwira ndipo zimakhala zodzaza pang'ono kuposa zomwe zinawonetsedwa pa LG OLED.
Kumanja kwa chithunzichi ndi zitsanzo za ma TV omwe ali ndi ma CD kuchokera ku TCL ndi Hisense.
Kugwiritsiridwa ntchito kwa Quantum Dots kwabwera kwambiri pamene ojambula TV ambiri adawonetsera ma TV omwe ali ndi mphamvu zowonjezera pa 2016 CES, kuphatikizapo Samsung, TCL, Hisense / Sharp, Vizio, ndi Philips.
Komabe, mochititsa chidwi, LG, yomwe inawonetsa zina zotchedwa Quantum Dot TV mu 2015 , mwachiwonekere yatsimikiza kubwerera, ndikuyika zinthu zambiri mu matepi awo olemera a OLED TV.
