一、 Yisiphi isizathu esiyinhloko senkinga yokuboniswa kwe-LED okubonisa uhhafu wesikrini kuphela?
Kufanele siyilungise kanjani?
1. Isethi yendawo yesibonisi ayilungile: Lokhu kungalungiswa ngokusetha kabusha usayizi wendawo yesibonisi kusofthiwe yokudlala isikrini sokubonisa.
2. Ukusetha usayizi wefonti mkhulu kakhulu: usalungisa usayizi wefonti ngenkathi udlala isofthiwe
3. Udaba lwebhodi leyunithi: Yebo, ibhodi liphukile futhi alikwazi ukuvezwa.Akuvamile ukushintsha ibhodi
Inkinga efana nale ngokuvamile inkinga yokusetha.Kungenzeka futhi ukuthi iyunithi ayisebenzi kahle.Kodwa amathuba mancane uma kuqhathaniswa.Ake sibheke inkinga efanayo njengoba kukhonjisiwe emfanekisweni:
Le nkinga ibangelwa kakhulu izinkinga ze-hardware, ngokuvamile ezibangelwa izinkinga ezilandelayo.
1. Inkinga yentambo yamandla: Njengento yokuqala engabaliwe.Kungenzeka kakhulu ukuthi intambo yamandla ebhodini leyunithi ixege, okuholela ekubonisweni okungaphelele.
2. Inkinga yokunikezwa kwamandla: Lokhu kuvame ukubangelwa ukungasebenzi kahle kwemojula yamandla, futhi ukunikezwa kwamandla kumele kushintshwe, kodwa lesi simo asivamile.Njengenhloso yesibili yophenyo.
3. Lawula umonakalo wekhadi: Ukulimala kwekhadi lokulawula kubangela amaphutha okudlulisa idatha noma ukudluliswa okungaphelele.
4. Udaba lwebhodi leyunithi: Yebo, ibhodi liphukile futhi alikwazi ukuvezwa.Akuvamile ukushintsha ibhodi.
二、 Ungakusingatha kanjani ukuchezuka kombala kuzikrini zokubonisa ze-LED?
Uma ubheka ohlangothini lwemojuli yesibonisi ye-LED, ukuchezuka kombala nokuhlobisa phakathi kwamamojula akuhambisani.Yini inkinga?
Okokuqala, qonda izizathu eziyinhloko zokuphambuka kombala wamamojula wokubonisa we-LED:
1. Izinkinga ngezibani ze-LED: (kufaka phakathi amapharamitha we-chip angahambisani, amaphutha ekupakishweni okunamathelayo, amaphutha okubeka ngesikhathi sokulungiswa kwekristalu, namaphutha ngesikhathi sokuhlukaniswa kombala), okungathinta ubude begagasi obuphumayo, ukukhanya, kanye ne-engeli yezibani ze-LED eqoqweni elifanayo. .Ngakho-ke, kunenqubo ebaluleke kakhulu ekukhiqizeni izibonisi ze-elekthronikhi ze-LED: izibani zokuxuba.Xuba zonke izibani ze-LED zombala ofanayo ngokulinganayo ngaphambi kokuwafaka ku-PCB.Inzuzo yokwenza kanjalo ukuthi ingagwema ukuphambuka kombala wendawo wemojula ye-LED.
2. Inqubo yokukhiqiza: Ngemva kokuba imojula ye-LED idlulele ekufakweni kwe-wave soldering futhi indawo ye-LED isilungisiwe, akufanele iphinde inyakaze.Kodwa izinkampani eziningi zivame ukushayisana futhi zigobe izibani ze-LED ngesikhathi sokuhlola, ukulungisa, ukushisela, ukuguga, nezinqubo zokudlulisa ngenxa yokuntuleka kwezimo zokuvikela.Khona-ke, ngaphambi kokufaka i-glue, kwenziwa lokho okubizwa ngokuthi umugqa wonke, okungabangela kalula ukuthi izibani esikrinini se-LED zitsheke ngokungavamile, okuholela ekuphambukeni kombala wemodyuli.
3. Udaba lokuphakelwa kwamandla: Lapho uklama izikrini zokubonisa i-LED, kunzima ukuqonda ngokucacile izinto okufanele zisetshenziswe (okuhlanganisa ukukhethwa kanye nenani lokuphakelwa kukagesi), okuholela ezinkingeni ohlelweni lokuphakelwa kwamandla kanye nokungalingani kwamandla kagesi. Amamojula we-LED.
4. Isistimu yokulawula ne-IC yokulawula: Ngenxa yokuthi abakhiqizi besikrini sokubonisa i-LED abanawo amandla okuklama, ukuthuthukiswa, ukuhlola, nokukhiqiza amasistimu okulawula isikrini esibonisiwe se-LED nama-IC okulawula.Isikrini sokubonisa esikhiqiziwe asikwazi ukuqinisekiswa, into kuphela engenziwa ukulungisa amapharamitha ahlukahlukene.
Ngakho-ke, lapho inkinga yokuchezuka kombala wemojula yesibonisi se-LED ibangelwa izibani ze-LED nenqubo yokukhiqiza, imojuli ingalungiswa kuphela noma ishintshwe.Uma kuyinkinga yokunikezwa kwamandla, kuyadingeka ukuthi kushintshwe isibani samandla, njll. Uma kuyinkinga ngesistimu yokulawula ne-IC, singacela kuphela umenzi ukuthi ayilungise noma ayixazulule.
Okungenhla yizimbangela ezivamile nezisombululo zamaphutha wokuboniswa kwesikrini somugqa we-LED, kusukela kokulula kuye kokuyinkimbinkimbi, kanye nokuxazulula izinkinga ezivame kakhulu ngayinye ngayinye.
