Leli phepha lidingida izimbangela nezisombululo zento edonsayo yesikrini esincane sokubonisa isikhala se-LED enombala ogcwele incazelo ephezulu!
Izinhlelo zokusebenza ze-LED ezinombala ogcwele zivame ukuba sesimweni sokudlala ividiyo ku-loop, futhi lesi sibonisi esiguqukayo sizoshaja amandla e-parasitic wekholomu noma ulayini lapho ulayini ushintshwa, okubangela ezinye izibani ze-LED okungafanele zikhanyiswe kulokhu. umzuzu wokuvela kumnyama, okubizwa ngokuthi "ukuhudula isithunzi".
Izizathu eziyinhloko zento yokuhudula yilezi ezilandelayo:
① Inkinga yomshayeli wekhadi levidiyo.Ungazama ukubuyekeza umshayeli wekhadi lezithombe noma ufake kabusha umshayeli wekhadi lezithombe.Ngesikhathi esifanayo, kunconywa ukulungisa ukulungiswa kanye nezinga lokuvuselela, okungenzeka futhi lihlobene nesikhathi sokuphendula sesibonisi se-LCD.
② Inkinga yekhadi levidiyo.Ungazama ukuyixhuma futhi futhi uhlanze umunwe osagolide.Ngasikhathi sinye, ungabheka ukuthi isifanisi sekhadi lezithombe sisebenza ngokujwayelekile yini.
③ Inkinga yomugqa wedatha.Kuyadingeka ukufaka esikhundleni sekhebula ledatha noma uhlole ukuthi ikhebula ledatha ligobile yini.
④ Inkinga yekhebula lesikrini.Okusho ukuthi, ikhebula le-VGA.Hlola ukuthi le khebula ixhumeke kahle yini nokuthi ayikhululekile yini.Zama ukushintsha ikhebuli ye-VGA yekhwalithi ephezulu.Ngaphezu kwalokho, ikhebula le-VGA kufanele libe kude nekhebula lamandla.
⑤ Inkinga yokubonisa.Xhuma imonitha kwenye ikhompuyutha evamile.Uma inkinga iqhubeka, kungase kube inkinga yokuqapha.
Ubuchwepheshe bokuqeda ithunzi besikrini sokubonisa se-LED bungenza isithombe esibukwayo sibe bucayi kakhulu futhi kwenze isibonisi sesithombe sifinyelele ikhwalithi yesithombe ecacayo;Ukusetshenziswa kwamandla okuphansi kungonga amandla kagesi ngesikhathi sokusetshenziswa kwesikhathi eside kwesikrini sokubonisa se-LED ukuze kuhlangatshezwane nezidingo zohlelo lokusebenza lwezindleko eziphansi nokongiwa kwamandla nokuvikelwa kwemvelo;Uma izinga lokuvuselela liphezulu, kulapho isithombe esiboniswayo sizinze khona, sinikeza ukusekela kobuchwepheshe kokuboniswa okuhle nekhwalithi ephezulu, futhi lo mphumela wokubonisa uphinde wenze iso lomuntu lizizwe likhathele lapho libuka, futhi lingahlangabezana nezidingo zokuthatha izithombe ezinesivinini esikhulu.Yilokhu kanye okukhuthaze ukuthuthukiswa komphumela kuzo zonke izici, futhi kwaphinde kwakhuthaza kakhulu ukuthuthukiswa kobuchwepheshe bokusebenzisa kuso sonke isikrini sokubonisa i-LED.
Ubuchwepheshe bamanje bokuqeda ithunzi buqeda ngempumelelo into yokudonsa.Uma umugqa (n) kanye no-ROW (n+1) ushintsha imigqa, umsebenzi wamanje wokuqeda ithunzi ushaja ngokuzenzakalelayo amandla e-parasitic Cc.Uma umugqa (n+1) uvuliwe, amandla e-parasitic Cc ngeke akhokhiswe ngesibani 2, ngaleyo ndlela kuqedwe into yokudonsa.
Ukuze kuncishiswe ukusetshenziswa kwamandla kwezibonisi ze-LED, kwethulwe imikhiqizo yamandla aphansi.Yehlisa amandla kagesi wesikrini sokubonisa se-LED ngokunciphisa i-voltage yephoyinti le-inflection yamanje.Le ndlela iphinde yehlise i-voltage yokuphakelwa kwamandla, engaqeda ukumelana nokwehla kwe-voltage engu-1V okufanele ixhunywe ochungechungeni lwesibani esibomvu.Ngalezi ntuthuko ezimbili, ukusetshenziswa kwamandla okuphansi kanye nezinhlelo zokusebenza zekhwalithi ephezulu zingafinyelelwa.
Ngamafuphi, kungakhathaliseki ukuthi ubuchwepheshe bokuqeda noma ubuchwepheshe bamanje bokuqeda, indima ebaluleke kakhulu yobuchwepheshe bokushayela ukwenza isithombe sizinze futhi sicace, njengedrayivu yekhadi lezithombe zekhompyutha, ukuqinisekisa ikhwalithi yesithombe esibushelelezi, futhi ekugcineni uzuze. ukunemba kwencazelo ephezulu yesibonisi se-LED esinemibala egcwele.
