M'dziko la mauthenga owonetsera, pakhala pali mkangano wokhudza teknoloji yomwe ili bwino, LED kapena LCD.Onse awiri ali ndi ubwino ndi zovuta zake, ndipo nkhondo yomenyera malo apamwamba mumsika wamakhoma a kanema ikupitirirabe.
Zikafika pamkangano wapakhoma wa kanema wa LED vs. LCD, zitha kukhala zovuta kusankha mbali.Kuchokera ku kusiyana kwa teknoloji kupita ku khalidwe lachithunzi.Pali zinthu zingapo zomwe muyenera kuziganizira posankha njira yomwe ili yoyenera kwambiri pa zosowa zanu.
Ndi msika wapadziko lonse lapansi wamakhoma amakanema wakhazikitsidwa kuti ukule ndi 11% pofika chaka cha 2026, sipanakhalepo nthawi yabwinoko yozindikira zowonetsera izi.
Kodi mumasankha bwanji chiwonetsero chokhala ndi chidziwitso chonsechi kuti muganizire ngakhale?
Kodi pali kusiyana kotani?
Poyamba, zowonetsera zonse za LED ndi ma LCD okha.Onse amagwiritsa ntchito ukadaulo wa Liquid Crystal Display (LCD) ndi nyali zingapo zomwe zimayikidwa kumbuyo kwa chinsalu kuti apange zithunzi zomwe timawona pazithunzi zathu.Zowonetsera za LED zimagwiritsa ntchito ma diode otulutsa kuwala kwa nyali zakumbuyo, pomwe ma LCD amagwiritsa ntchito nyali za fulorosenti.
Ma LED amathanso kukhala ndi zowunikira zonse.Apa ndi pamene ma LED amayikidwa mofanana pawindo lonse, mofanana ndi LCD.Komabe, kusiyana kofunikira ndikuti ma LED ayika madera ndipo maderawa amatha kuzimiririka.Izi zimadziwika kuti dimming yakwanuko ndipo zimatha kukonza bwino kwambiri zithunzi.Ngati gawo lina la chinsalu likufunika kukhala lakuda kwambiri, zoni ya ma LED atha kuchepetsedwa kuti apange mtundu wakuda weniweni komanso kusiyanitsa kwazithunzi.Zowonetsera za LCD sizitha kuchita izi chifukwa zimayatsidwa nthawi zonse.
Khoma la kanema wa LCD pamalo olandirira ofesi
Chithunzi khalidwe
Ubwino wa zithunzi ndi imodzi mwa nkhani zokangana kwambiri zikafika pamkangano wapakhoma wa kanema wa LED ndi LCD.Zowonetsera za LED nthawi zambiri zimakhala ndi zithunzi zabwinoko poyerekeza ndi ma LCD.Kuchokera pamiyezo yakuda mpaka kusiyanitsa komanso kulondola kwamtundu, zowonetsera za LED nthawi zambiri zimatuluka pamwamba.Zowonetsera za LED zokhala ndi zowunikira zowoneka bwino zakumbuyo zomwe zimatha kuzimiririka kwanuko zimapereka chithunzi chabwino kwambiri.
Pankhani yowonera, nthawi zambiri palibe kusiyana pakati pa makoma a LCD ndi ma LED.Izi m'malo mwake zimadalira mtundu wa galasi logwiritsidwa ntchito.
Funso loyang'ana mtunda likhoza kubwera muzokambirana za LED vs. LCD.Mwambiri, palibe mtunda waukulu pakati pa matekinoloje awiriwa.Ngati owonerera aziwonera chapafupi chinsalucho chimafunika kuchulukira kwambiri kwa pixel mosasamala kanthu kuti khoma lanu la kanema limagwiritsa ntchito ukadaulo wa LED kapena LCD.
Kukula
Kumene chiwonetserocho chidzayikidwe ndi kukula kofunikira ndizinthu zazikulu zomwe skrini ili yoyenera kwa inu.
Makoma a kanema a LCD nthawi zambiri samapangidwa akulu ngati makoma a LED.Kutengera kufunikira, amatha kukhazikitsidwa mosiyana koma sangapite kumitundu yayikulu ya makoma a LED.Ma LED atha kukhala akulu momwe mungafunire, amodzi mwa akulu kwambiri ali ku Beijing, omwe amayesa 250 mx 30 m (820 ft x 98 ft) pamalo okwana 7,500 m² (80,729 ft²).Chiwonetserochi chimapangidwa ndi zowonetsera zisanu zazikulu kwambiri za LED kuti zipange chithunzi chimodzi chosalekeza.
Kuwala
Kumene mudzakhala mukuwonetsera khoma lanu lavidiyo lidzakudziwitsani momwe mungafunikire zowonetsera kuti zikhale zowala.
Kuwala kwakukulu kudzafunika m'chipinda chokhala ndi mazenera akuluakulu ndi kuwala kochuluka.Komabe, m'zipinda zambiri zowongolera kuwala kwambiri kumakhala koyipa.Ngati antchito anu akugwira ntchito mozungulira kwa nthawi yayitali amatha kudwala mutu kapena kupsinjika kwamaso.Izi zikachitika, LCD ingakhale njira yabwinoko chifukwa sipafunikanso mulingo wowala kwambiri.
Kusiyanitsa
Kusiyanitsa kulinso chinthu choyenera kuganizira.Uku ndiye kusiyana pakati pamitundu yowala kwambiri komanso yakuda kwambiri.Kusiyanitsa kofananira kwa zowonetsera za LCD ndi 1500: 1, pomwe ma LED amatha kukwaniritsa 5000: 1.Ma LED okhala ndi mawonekedwe owoneka bwino amatha kuwunikira kwambiri chifukwa chowunikiranso komanso akuda owoneka bwino okhala ndi dimming yakomweko.
Opanga mawonedwe otsogola akhala otanganidwa kukulitsa mizere yazinthu zawo kudzera muzopanga zatsopano komanso kupita patsogolo kwaukadaulo.Zotsatira zake, mawonekedwe owonetsera apita patsogolo kwambiri, ndi zowonetsera za Ultra High Definition (UHD) ndi zowonetsera 8K kukhala muyeso watsopano muukadaulo wapakhoma lamavidiyo.Kupita patsogolo kumeneku kumapangitsa kuti wowonera aliyense aziwoneka mozama kwambiri.
Pomaliza, kusankha pakati pa matekinoloje a pakhoma la kanema wa LED ndi LCD kumadalira momwe wogwiritsa ntchitoyo amafunira komanso zomwe amakonda.Ukadaulo wa LED ndi wabwino pakutsatsa kwakunja komanso zowoneka bwino, pomwe ukadaulo wa LCD ndi woyenera pazokonda zamkati momwe zithunzi zowoneka bwino zimafunikira.Pamene matekinoloje awiriwa akupitilirabe bwino, makasitomala amatha kuyembekezera zowoneka bwino komanso mitundu yozama kuchokera pamakoma awo amakanema.
