Ezweni lezokuxhumana ezibukwayo, bekulokhu kunenkulumompikiswano mayelana nokuthi ibuphi ubuchwepheshe obungcono, i-LED noma i-LCD. Kokubili kunezinzuzo kanye nokubi, futhi impi yendawo ephezulu emakethe yodonga lwevidiyo iyaqhubeka.
Uma kuziwa engxoxweni yodonga lwevidiyo ye-LED vs. LCD, kungaba nzima ukukhetha uhlangothi. Kusukela ekuhlukeni kwezobuchwepheshe kuya kukhwalithi yesithombe.Kunezici ezimbalwa ozodinga ukuzicabangela lapho ukhetha ukuthi yisiphi isisombululo esifanele izidingo zakho.
Njengoba imakethe yodonga lwamavidiyo emhlabeni wonke isethwe ukuthi ikhule ngo-11% ngo-2026, asikaze sibe nesikhathi esingcono sokubhekana nalezi zibonisi.
Ukhetha kanjani isibonisi esinalo lonke lolu lwazi ongacatshangelwa kodwa?
Uyini umehluko?
Okokuqala, zonke izibonisi ze-LED zingama-LCD nje. Bobabili basebenzisa ubuchwepheshe be-Liquid Crystal Display (LCD) kanye nochungechunge lwamalambu abekwe ngemuva kwesikrini ukukhiqiza izithombe esizibona ezikrinini zethu. Izikrini ze-LED zisebenzisa ama-diode akhipha ukukhanya kumalambu angemuva, kuyilapho ama-LCD esebenzisa amalambu angemuva e-fluorescent.
Ama-LED angaba nokukhanya okugcwele kohlu. Yilapho ama-LED abekwe ngokulinganayo kuso sonke isikrini, ngendlela efanayo neye-LCD. Kodwa-ke, umehluko obalulekile ukuthi ama-LED anezindawo ezimisiwe futhi lezi zindawo zingafiphazwa. Lokhu kwaziwa njengokufiphala kwendawo futhi kungathuthukisa kakhulu ikhwalithi yesithombe. Uma ingxenye ethile yesikrini idinga ukuba mnyama, izoni yama-LED ingafiphazwa ukuze kudalwe okumnyama okweqiniso kanye nokugqama okuthuthukisiwe kwesithombe. Izikrini ze-LCD azikwazi ukwenza lokhu njengoba zihlala zikhanya ngokulinganayo.
Udonga lwevidiyo ye-LCD endaweni yokwamukela ihhovisi
Ikhwalithi yesithombe
Ikhwalithi yesithombe ingenye yezinkinga ezibangwa kakhulu uma kukhulunywa nge-LED vs. LCD video wall. Izibonisi ze-LED ngokuvamile zinekhwalithi yesithombe engcono uma kuqhathaniswa nozakwabo be-LCD. Kusukela kumazinga amnyama kuye kokungafani ngisho nokunemba kombala, izibonisi ze-LED ngokuvamile ziphuma phezulu. Izikrini ze-LED ezinohlelo olugcwele olukhanyiselwe emuva ezikwazi ukufiphalisa indawo zizohlinzeka ngekhwalithi yesithombe ehamba phambili.
Mayelana ne-engeli yokubuka, ngokuvamile awukho umehluko phakathi kwezindonga zevidiyo ze-LCD ne-LED. Lokhu kunalokho kuncike kwikhwalithi yephaneli yengilazi esetshenzisiwe.
Umbuzo webanga lokubuka ungase uqhamuke ezingxoxweni ze-LED vs. LCD. Ngokuvamile, alikho ibanga elikhulu phakathi kobuchwepheshe obubili. Uma ababukeli bezobe bebukele eduze isikrini sidinga ukuminyana kwamaphikseli aphezulu kungakhathaliseki ukuthi udonga lwevidiyo yakho lisebenzisa ubuchwepheshe be-LED noma be-LCD.
Usayizi
Lapho isibonisi sizobekwa khona kanye nosayizi odingekayo yizici ezibalulekile lapho isikrini sikulungele khona.
Izindonga zevidiyo ze-LCD ngokuvamile azenziwa zibe zinkulu njengezindonga ze-LED. Kuye ngesidingo, zingacushwa ngokuhlukile kodwa ngeke ziye kumasayizi amakhulu wezindonga ze-LED. Ama-LED angaba makhulu ngokudingayo, enye yawo enkulu ise-Beijing, ekala u-250 mx 30 m (820 ft x 98 ft) endaweni ephelele engu-7,500 m² (80,729 ft²). Lesi sibonisi sakhiwe izikrini ezinhlanu ze-LED ezinkulu kakhulu ukukhiqiza isithombe esisodwa esiqhubekayo.
Ukukhanya
Lapho uzobe ubonisa khona udonga lwevidiyo yakho kuzokwazisa ukuthi udinga ukuthi izikrini zikhanye kangakanani.
Kuzodingeka ukukhanya okuphakeme ekamelweni elinamafasitela amakhulu nokukhanya okuningi. Kodwa-ke, emakamelweni amaningi okulawula ukukhanya kakhulu kungase kube okungalungile. Uma abasebenzi bakho besebenza ngaso isikhathi eside bangase baphathwe yikhanda elibuhlungu noma iso. Kulesi simo, i-LCD ingaba inketho engcono njengoba asikho isidingo sezinga eliphezulu lokukhanya.
Qhathanisa
Ukuqhathanisa nakho kuyinto okufanele icatshangelwe. Lona umehluko phakathi kwemibala egqame kakhulu nemnyama kakhulu yesikrini. Isilinganiso esijwayelekile sokungafani sezibonisi ze-LCD singu-1500:1, kuyilapho ama-LED angathola u-5000:1. Ama-LED anohlelo oluphelele olukhanyiselwe emuva anganikeza ukukhanya okuphezulu ngenxa yokukhanyisa ngemuva kodwa futhi nomnyama oqinile onokufiphala kwendawo.
Abakhiqizi bezibonisi abahamba phambili bebematasa benweba imigqa yemikhiqizo yabo ngemiklamo emisha kanye nentuthuko yezobuchwepheshe. Ngenxa yalokho, ikhwalithi yokuboniswa iye yaba ngcono kakhulu, ngezikrini ze-Ultra High Definition (UHD) nezibonisi ze-8K zokucaca okuba yindinganiso entsha kubuchwepheshe bodonga lwevidiyo. Lezi ntuthuko zidala umuzwa wokubukwayo ogxile kakhulu kunoma yisiphi isibukeli.
Sengiphetha, ukukhetha phakathi kobuchwepheshe bodonga lwevidiyo ye-LED ne-LCD kuncike ohlelweni lomsebenzisi kanye nalokho akuthandayo. Ubuchwepheshe be-LED bulungele ukukhangisa kwangaphandle kanye nemiphumela emikhulu yokubuka, kuyilapho ubuchwepheshe be-LCD bufaneleka kangcono izilungiselelo zasendlini lapho kudingeka khona izithombe zokucaca okuphezulu. Njengoba lobu buchwepheshe buqhubeka buthuthuka, amakhasimende angalindela ukubukeka okuhlaba umxhwele nakakhulu nemibala ejulile ezindongeni zevidiyo.
