Ukukhethwa kwesikhala sephoyinti lesibonisi se-LED kuhlobene nezinto ezimbili:
Okokuqala, ibanga lokubuka lesibonisi se-LED
Sibekwe kuphi isikrini sokubonisa, nokuthi abantu bame kude kangakanani ukuze basibuke, kuyisici esibalulekile ekunqumeni ukuphakama kwamachashazi lapho ukhetha isikrini sokubonisa se-LED.
Ngokuvamile, kunefomula yebanga lokubuka elilungile = i-dot pitch/(0.3~0.8), okuwububanzi obulinganiselwe.Isibonelo, kusibonisi esinobude bephikseli obungu-16mm, ibanga lokubuka elingcono kakhulu lingamamitha angu-20~54.Uma ibanga lesiteshi liseduze kunebanga elincane, ungakwazi ukuhlukanisa amaphikseli esikrini sokubonisa.I-graininess inamandla, futhi ungamela kude.Manje, iso lomuntu alikwazi ukuhlukanisa izici zemininingwane.(Sihlose ukubona okuvamile, ngaphandle kwe-myopia kanye ne-hyperopia).Eqinisweni, lokhu futhi kuyisibalo esinzima.
Ezikrinini ze-LED zangaphandle, i-P10 noma i-P12 imvamisa isetshenziselwa ibanga elifushane, i-P16 noma i-P20 kwezikude, kanye ne-P4~P6 yezikrini zokubonisa zasendlini, kanye ne-P7.62 noma i-P10 kwezikude.
Okwesibili, inani lamaphikseli esibonisi se-LED
Kuvidiyo, ifomethi eyisisekelo yi-VCD enesinqumo esingu-352288, futhi ifomethi ye-DVD ingu-768576. Ngakho-ke, kwesikrini sevidiyo, sincoma ukuthi ukulungiswa okuncane kungabi ngaphansi kuka-352*288, ukuze umphumela wokubonisa ube muhle ngokwanele.Uma iphansi, ingaboniswa, kodwa ngeke izuze imiphumela engcono.
Ezibonisini ze-LED ezinombala owodwa nokabili oyinhloko ezibonisa kakhulu umbhalo nezithombe, izimfuneko zokulungiswa aziphezulu.Ngokosayizi wangempela, isibonisi esincane sefonti yesi-9 singanqunywa ngokuya ngevolumu yombhalo wakho.
Ngakho-ke, ngokuvamile khetha isibonisi se-LED, iphimbo lamachashazi libe lincane, ngcono, ukulungiswa kuzoba phezulu, nesibonisi sizocaca.Kodwa-ke, izici ezifana nezindleko, isidingo, kanye nobubanzi besicelo nazo kufanele zicatshangelwe ngokugcwele.
