Kwihlabathi lonxibelelwano olubonakalayo, bekusoloko kukho ingxoxo malunga nokuba loluphi ubuchwephesha olungcono, i-LED okanye i-LCD. Zombini zinezibonelelo kunye neengxaki, kwaye idabi lendawo ephezulu kwimarike yodonga lweevidiyo liyaqhubeka.
Xa kufikwa kwingxoxo yodonga lwevidiyo phakathi kwe-LED kunye ne-LCD, kunokuba nzima ukukhetha icala. Ukusuka kumahluko kwezobuchwepheshe ukuya kumgangatho womfanekiso. Kukho izinto ezininzi ekufuneka uziqwalasele xa ukhetha isisombululo esifanelekileyo kwiimfuno zakho.
Njengoko imakethi yeevidiyo kwihlabathi liphela iza kukhula nge-11% ngo-2026, akukho xesha lingcono kunaleli lokuqalisa ukusebenzisa ezi ziboniso.
Ukhetha njani isibonisi esinalo lonke olu lwazi oza kuluqwalasela?
Yintoni umahluko?
Okokuqala, zonke izibonisi ze-LED zii-LCD kuphela. Zombini zisebenzisa ubuchwepheshe be-Liquid Crystal Display (LCD) kunye nothotho lwezibane ezibekwe ngasemva kwesikrini ukuvelisa imifanekiso esiyibonayo kwizikrini zethu. Izikrini ze-LED zisebenzisa ii-diode ezikhupha ukukhanya kwizibane zangasemva, ngelixa ii-LCD zisebenzisa izibane zangasemva ze-fluorescent.
Ii-LED zinokuba nokukhanya okupheleleyo. Kulapho ii-LED zibekwe khona ngokulinganayo kwisikrini sonke, ngendlela efanayo ne-LCD. Nangona kunjalo, umahluko obalulekileyo kukuba ii-LED zineendawo ezimiselweyo kwaye ezi ndawo zinokufiphaliswa. Oku kwaziwa ngokuba kukufa kwengingqi kwaye kunokuphucula kakhulu umgangatho womfanekiso. Ukuba inxalenye ethile yesikrini kufuneka ibe mnyama, indawo yee-LED inokufiphaliswa ukuze kudalwe umnyama oyinyani kunye nomahluko ophuculweyo womfanekiso. Izikrini ze-LCD azikwazi ukwenza oku njengoko zihlala zikhanyiswe ngokulinganayo.

Umgangatho womfanekiso
Umgangatho womfanekiso ngomnye wemiba ephikiswana kakhulu xa kufikwa kwingxoxo phakathi kwe-LED kunye ne-LCD. Izikrini ze-LED zihlala zinomgangatho ongcono womfanekiso xa kuthelekiswa nezinye ze-LCD. Ukusuka kumanqanaba amnyama ukuya kumahluko kunye nokuchaneka kombala, izikrini ze-LED zihlala ziphuma phezulu. Izikrini ze-LED ezinesikrini esikhanyayo ngasemva esipheleleyo esikwaziyo ukufiphala kwendawo ziya kubonelela ngomgangatho ongcono womfanekiso.
Ngokuphathelele i-engile yokujonga, akukho mahluko phakathi kweendonga zevidiyo ze-LCD kunye ne-LED. Oku kuxhomekeke kumgangatho wephaneli yeglasi esetyenzisiweyo.
Umba womgama wokubukela unokuvela kwiingxoxo ze-LED vs. LCD. Ngokubanzi, akukho mgama mkhulu phakathi kwezi teknoloji zimbini. Ukuba ababukeli baza kubukela bekufutshane, isikrini sifuna uxinano olukhulu lwee-pixel nokuba udonga lwakho lwevidiyo lusebenzisa iteknoloji ye-LED okanye ye-LCD.
Ubungakanani
Apho isikrini siza kubekwa khona kunye nobukhulu obufunekayo zezona zinto zibalulekileyo ezenza isikrini sikulungele.
Iindonga zevidiyo ze-LCD azisoloko zenziwe zibe nkulu njengeendonga ze-LED. Ngokuxhomekeke kwimfuneko, zinokucwangciswa ngokwahlukileyo kodwa aziyi kufikelela kubukhulu obukhulu obunokwenziwa ziindonga ze-LED. Ii-LED zinokuba nkulu kangangoko ufuna, enye yezona zinkulu iseBeijing, enomlinganiselo we-250 mx 30 m (820 ft x 98 ft) womphezulu opheleleyo we-7,500 m² (80,729 ft²). Esi siboniso senziwe zizikrini ze-LED ezintlanu ezinkulu kakhulu ukuvelisa umfanekiso omnye oqhubekayo.
Ukukhanya
Apho uza kubonisa khona udonga lwakho lwevidiyo kuza kukwazisa ukuba ufuna izikrini zibe mhlophe kangakanani.
Ukukhanya okuphezulu kuya kufuneka kwigumbi elineefestile ezinkulu kunye nokukhanya okuninzi. Nangona kunjalo, kumagumbi amaninzi okulawula ukukhanya kakhulu kuya kuba yinto embi. Ukuba abasebenzi bakho basebenza kuyo ixesha elide banokuba neentloko ezibuhlungu okanye ukukhathazwa kwamehlo. Kule meko, i-LCD ingaba lolona khetho lungcono kuba akukho mfuneko yokukhanya okuphezulu.
Umahluko
Umahluko umele uqwalaselwe. Lo ngumahluko phakathi kwemibala ekhanyayo nemnyama kwesikrini. Umlinganiselo oqhelekileyo womahluko kwizikrini ze-LCD yi-1500:1, ngelixa ii-LED zinokufikelela kwi-5000:1. Ii-LED ezikhanyisiweyo ngokupheleleyo zinokubonelela ngokukhanya okuphezulu ngenxa yokukhanya okungasemva kodwa zikwanombala omnyama ocacileyo kunye nokufiphala kwendawo.
Abavelisi abaphambili bemiboniso bebexakekile besandisa uluhlu lwemveliso yabo ngoyilo olutsha kunye nophuhliso lwetekhnoloji. Ngenxa yoko, umgangatho wemiboniso uphucuke kakhulu, kunye nezikrini ze-Ultra High Definition (UHD) kunye nezikrini zesisombululo se-8K zibe ngumgangatho omtsha kubuchwepheshe bevidiyo eludongeni. Olu phuculo ludala amava okubona anzulu ngakumbi kuye nawuphi na umbukeli.
Ukuqukumbela, ukhetho phakathi kobuchwepheshe bevidiyo be-LED kunye ne-LCD luxhomekeke kwisicelo somsebenzisi kunye nokukhetha kwakhe. Ubuchwepheshe be-LED bufanelekile kwintengiso yangaphandle kunye neziphumo ezibonakalayo ezinkulu, ngelixa ubuchwepheshe be-LCD bufanelekile ngakumbi kwiindawo zangaphakathi apho kufuneka imifanekiso enesisombululo esiphezulu. Njengoko ezi teknoloji zimbini ziqhubeka ziphucuka, abathengi banokulindela imifanekiso enomtsalane ngakumbi kunye nemibala enzulu kwiindonga zabo zevidiyo.
