Ezweni lokuxhumana okubonakalayo, bekulokhu kunempikiswano ngokuthi ubuchwepheshe bungcono, i-LED noma i-LCD. Zombili zinezinzuzo kanye nokungalungi, futhi impi yendawo ephezulu emakethe yodonga lwamavidiyo iyaqhubeka.
Uma kukhulunywa ngempikiswano yodonga lwevidiyo ye-LED vs. LCD, kungaba nzima ukukhetha uhlangothi. Kusukela kumehluko kwezobuchwepheshe kuya kwikhwalithi yesithombe. Kunezici eziningana okuzodingeka uzicabangele lapho ukhetha ukuthi yisiphi isisombululo esifaneleka kakhulu izidingo zakho.
Njengoba imakethe yomhlaba wonke yodonga lwamavidiyo izokhula ngo-11% ngo-2026, akukaze kube nesikhathi esingcono kunalesi sokuqonda lezi zibonisi.
Ukhetha kanjani isibonisi esinalo lonke lolu lwazi okufanele ulucabangele?
Uyini umehluko?
Okokuqala, zonke izibonisi ze-LED zingama-LCD kuphela. Zombili zisebenzisa ubuchwepheshe be-Liquid Crystal Display (LCD) kanye nochungechunge lwezibani ezibekwe ngemuva kwesikrini ukuze zikhiqize izithombe esizibonayo ezikrinini zethu. Izikrini ze-LED zisebenzisa ama-diode akhipha ukukhanya ezibanini zangemuva, kuyilapho ama-LCD esebenzisa izibani zangemuva ze-fluorescent.
Ama-LED angaba nokukhanya okugcwele. Yilapho ama-LED ebekwa khona ngokulinganayo kuso sonke isikrini, ngendlela efanayo ne-LCD. Kodwa-ke, umehluko obalulekile ukuthi ama-LED anezindawo ezibekiwe futhi lezi zindawo zingafiphazwa. Lokhu kwaziwa ngokuthi ukufiphaza kwendawo futhi kungathuthukisa kakhulu ikhwalithi yesithombe. Uma ingxenye ethile yesikrini idinga ukuba mnyama, indawo yama-LED ingafiphazwa ukuze kudalwe umnyama weqiniso kanye nokungafani kwesithombe okuthuthukisiwe. Izikrini ze-LCD azikwazi ukwenza lokhu njengoba zihlala zikhanya ngokulinganayo.
Udonga lwevidiyo ye-LCD endaweni yokwamukela izivakashi ehhovisi
Ikhwalithi yesithombe
Ikhwalithi yesithombe ingenye yezinkinga eziphikisana kakhulu uma kukhulunywa ngempikiswano yodonga lwevidiyo phakathi kwe-LED ne-LCD. Izibonisi ze-LED ngokuvamile zinekhwalithi yesithombe engcono uma kuqhathaniswa nezinye ze-LCD. Kusukela emazingeni amnyama kuya ekuqhathaniseni ngisho nokunemba kombala, izibonisi ze-LED zivame ukuphuma phezulu. Izikrini ze-LED ezinesibonisi esigcwele esikhanyayo emuva esikwazi ukufiphaza kwendawo zizonikeza ikhwalithi yesithombe engcono kakhulu.
Ngokuphathelene ne-engeli yokubuka, ngokuvamile akukho mehluko phakathi kwezindonga zevidiyo ze-LCD neze-LED. Lokhu kuncike ekhwalithini yephaneli yengilazi esetshenzisiwe.
Umbuzo webanga lokubuka ungase uvele ezingxoxweni ze-LED vs. LCD. Ngokuvamile, akukho ibanga elikhulu phakathi kwalezi zobuchwepheshe ezimbili. Uma ababukeli bezobukela beseduze, isikrini sidinga ubuningi bamaphikseli aphezulu kungakhathaliseki ukuthi udonga lwakho lwevidiyo lusebenzisa ubuchwepheshe be-LED noma be-LCD.
Usayizi
Ukuthi isikrini sizobekwa kuphi kanye nosayizi odingekayo yizinto ezibalulekile ezenza isikrini sikulungele.
Izindonga zevidiyo ze-LCD ngokuvamile azenziwa zibe zinkulu njengezindonga ze-LED. Kuye ngesidingo, zingahlelwa ngendlela ehlukile kodwa ngeke ziye ngobukhulu obukhulu izindonga ze-LED ezingaba nabo. Ama-LED angaba makhulu ngendlela oyidingayo, enye enkulu kunazo zonke iseBeijing, enobukhulu obungu-250 mx 30 m (820 ft x 98 ft) endaweni yonke engu-7,500 m² (80,729 ft²). Lesi sibonisi sakhiwe ngezikrini ze-LED ezinhlanu ezinkulu kakhulu ukukhiqiza isithombe esisodwa esiqhubekayo.
Ukukhanya
Lapho uzobonisa khona udonga lwakho lwevidiyo kuzokwazisa ukuthi udinga izikrini zikhanye kangakanani.
Ukukhanya okuphezulu kuzodingeka ekamelweni elinamafasitela amakhulu nokukhanya okuningi. Kodwa-ke, emakamelweni amaningi okulawula ukukhanya kakhulu kungaba yinto embi. Uma abasebenzi bakho besebenza ngakho isikhathi eside bangase bahlushwe yikhanda noma ukukhathala kwamehlo. Kulesi simo, i-LCD ingaba inketho engcono njengoba kungekho sidingo sezinga lokukhanya eliphakeme kakhulu.
Umehluko
Ukungafani nakho kuyinto okufanele icatshangelwe. Lona umehluko phakathi kwemibala ekhanyayo nemnyama kakhulu yesikrini. Isilinganiso esijwayelekile sokungafani kwezibonisi ze-LCD singu-1500:1, kuyilapho ama-LED engafinyelela ku-5000:1. Ama-LED agcwele i-backlight anganikeza ukukhanya okuphezulu ngenxa yokukhanya kwangemuva kodwa futhi abe mnyama ngokweqiniso kanye nokufiphala kwendawo.
Abakhiqizi bezibonisi abahamba phambili bebematasa bandisa imigqa yabo yemikhiqizo ngokusebenzisa imiklamo emisha kanye nentuthuko yezobuchwepheshe. Ngenxa yalokho, ikhwalithi yezibonisi ithuthuke kakhulu, njengoba izikrini ze-Ultra High Definition (UHD) kanye nezibonisi ze-8K resolution ziba indinganiso entsha kubuchwepheshe be-video wall. Lokhu kuthuthuka kudala okuhlangenwe nakho okubonakalayo okugxile kakhulu kunoma yimuphi umbukeli.
Ekuphetheni, ukukhetha phakathi kobuchwepheshe be-LED kanye nobodonga lwevidiyo lwe-LCD kuncike ekusetshenzisweni komsebenzisi kanye nokukhetha komuntu siqu. Ubuchwepheshe be-LED bufanelekela ukukhangisa kwangaphandle kanye nemiphumela emikhulu yokubuka, kuyilapho ubuchwepheshe be-LCD bufaneleka kangcono ezindaweni zangaphakathi lapho kudingeka khona izithombe ezinesinqumo esiphezulu. Njengoba lobu buchwepheshe buqhubeka nokuthuthuka, amakhasimende angalindela izithombe ezihlaba umxhwele kakhulu kanye nemibala ejulile ezindongeni zawo zevidiyo.
