Izikrini zokubonisa i-LEDziimveliso ze-elektroniki, kwaye ngamanye amaxesha kunokubakho iingxaki.Ngezantsi, siza kwazisa iindlela ezininzi eziqhelekileyo zokusombulula ingxaki.
01 Siyintoni isizathu semizuzwana embalwa yemigca eqaqambileyo okanye umfanekiso weskrini ongekho mfiliba kwiscreen se-LED xa siqala ukusebenza?
Emva kokudibanisa umlawuli omkhulu wesikrini kwikhompyutheni, ibhodi yokusabalalisa i-HUB, kunye neskrini ngokufanelekileyo, kuyimfuneko ukubonelela nge+5V unikezelo lwamandlakumlawuli ukuqinisekisa ukusebenza kwayo okuqhelekileyo (ngeli xesha, musa ukuyidibanisa ngokuthe ngqo kwi-voltage ye-220V).Ngomzuzu wokukhanya, kuya kubakho imizuzwana embalwa yemigca eqaqambileyo okanye "isikrini esimnyama" kwisikrini, zizinto eziqhelekileyo zovavanyo, ezikhumbuza umsebenzisi ukuba isikrini sele siza kuqalisa ukusebenza ngokwesiqhelo.Kwimizuzwana emi-2, le nto iya kunyamalala ngokuzenzekelayo kwaye isikrini siya kungena kwindlela eqhelekileyo yokusebenza.
02 Kutheni ingakwazi ukulayisha okanye ukunxibelelana?
Izizathu zokusilela konxibelelwano kunye nokusilela kokulayisha ziphantse zifane, ezinokubangelwa zezi zizathu zilandelayo.Nceda uthelekise izinto ezidwelisiweyo kunye nomsebenzi:
1. Qinisekisa ukuba i-hardware yesistim yolawulo inikwe amandla ngokufanelekileyo.
2. Khangela kwaye uqinisekise ukuba intambo ye-serial esetyenziselwa ukudibanisa umlawuli ngumgca ochanekileyo, kungekhona umgca we-crossover.
3. Khangela kwaye uqinisekise ukuba ucingo loqhagamshelwano lwe-serial port aluguquki kwaye akukho kukhululeka okanye ukuhlukana kuzo zombini iziphelo.
4. Thelekisa i-software yokulawula isikrini se-LED kunye nekhadi lokulawula elikhethileyo ukukhetha imodeli efanelekileyo yemveliso, indlela yokuhambisa, inombolo ye-serial port, kunye nesantya sothumelo lwe-serial.Cwangcisa idilesi kunye nesantya sothumelo lwe-serial kwi-hardware yesistim yolawulo ngokuchanekileyo ngokwedayagramu enikiweyo yokutshintsha ukucofa kwisoftware.
5. Khangela ukuba i-jumper cap ikhululekile okanye ivaliwe;Ukuba umnqwazi we-jumper awukhululekanga, nceda uqinisekise ukuba icala le-jumper cap lichanekile.
6. Ukuba emva kokutshekisha oku ngasentla kunye nezilungiso, kusekho ingxaki yokulayisha, nceda usebenzise i-multimeter ukulinganisa ukuba i-serial port yekhompyutheni edibeneyo okanye i-hardware yesistim yokulawula yonakalisiwe, ukuqinisekisa ukuba kufuneka ibuyiselwe kumenzi wekhompyutha. okanye i-hardware yenkqubo yolawulo yovavanyo.
03 Kutheni isikrini se-LED sibonakala simnyama ngokupheleleyo?
Kwinkqubo yokusebenzisa iisistim zolawulo, ngamanye amaxesha sidibana ne-phenomenon yezikrini ze-LED ezibonakala zimnyama ngokupheleleyo.Isenzeko esifanayo sinokubangelwa zizizathu ezahlukeneyo, nenkqubo yokuguqula isikrini ibe mnyama inokwahluka ngokuxhomekeke kwimisebenzi eyahlukeneyo okanye imo engqongileyo.Umzekelo, inokuba mnyama ngexesha lokukhanya, inokuba mnyama ngexesha lokulayisha, okanye ijike ibe mnyama emva kokuthumela, njalo njalo:
1. Nceda uqinisekise ukuba zonke ii-hardware, kubandakanywa nenkqubo yolawulo, zixhotyiswe ngokufanelekileyo.(+5V, musa umva okanye uqhagamshele ngokungalunganga)
2. Khangela kwaye uqinisekise ngokuphindaphindiweyo ukuba intambo ye-serial esetyenziselwa ukudibanisa umlawuli ikhululekile okanye ivaliwe.(Ukuba ijika ibe mnyama ngexesha lenkqubo yokulayisha, kunokwenzeka ngenxa yesi sizathu, oko kukuthi, iphazamisekile ngenxa yemigca yonxibelelwano ekhululekile ngexesha lenkqubo yonxibelelwano, ngoko isikrini sijika sibe mnyama. Musa ukucinga ukuba umzimba weskrini awushukumi. , kwaye imigca ayinakukhululeka. Nceda uyijonge ngokwakho, into ebalulekileyo ekusombululeni ingxaki ngokukhawuleza.)
3. Khangela kwaye uqinisekise ukuba ibhodi yokusabalalisa ye-HUB ixhunywe kwisikrini se-LED kunye nekhadi lokulawula eliphambili lixhunyiwe ngokuqinileyo kwaye lifakwe phezulu.
04 Isizathu sokuba kutheni isikrini sonke sebhodi yeyunithi singakhanyi okanye siluzizi
1. Hlola ngokubonakalayo iintambo zonikezelo lwamandla, iintambo zeribhoni ze-26P phakathi kweebhodi zeyunithi, kunye nezibane zemodyuli yemodyuli yamandla ukuze ubone ukuba zisebenza ngokufanelekileyo.
2. Sebenzisa i-multimeter ukulinganisa ukuba ibhodi yeyunithi ine-voltage eqhelekileyo, kwaye emva koko ulinganise ukuba i-voltage output yemodyuli yamandla iyinto eqhelekileyo.Ukuba akunjalo, kugwetywa ukuba imodyuli yamandla ayilungile.
3. Ukulinganisa i-voltage ephantsi yemodyuli yamandla kwaye ulungelelanise ukulungiswa okulungileyo (kufuphi nokukhanya kwesalathisi semodyuli yamandla) ukufezekisa umbane oqhelekileyo.
