Zeziphi iindlela zokugcina izikrini zokubonisa i-LED?

Bonisa indlela yokubona ukuxhathisa kwesikrini

Indlela yokufumanisa ukuxhathisa kwebonisa isikrini, kufuneka sibeke i-multimeter kuluhlu lokumelana.Okokuqala, kufuneka sibone ixabiso lokumelana ukusuka kwindawo ethile kwibhodi yesekethe eqhelekileyo ukuya emhlabeni, kwaye ke kufuneka sivavanye ukuba kukho umehluko phakathi kwendawo efanayo kwenye ibhodi yesiphaluka kunye nexabiso eliqhelekileyo lokumelana.Ukuba kukho umahluko, siya kulazi uluhlu lwengxaki ngesikrini sokubonisa, ngaphandle koko siya kuyihoya.

Bonisa indlela yokufumanisa amandla ombane wesikrini

Ukufunyanwa kombane wesikrini sokubonisa kukuseta i-multimeter kuluhlu lwe-voltage, ukubona i-voltage yomhlaba kwindawo ekurhanelwa ukuba yingxaki yesekethe, kwaye uyithelekise kunye neyangaphambili ukuze ubone ukuba iqhelekile.Ngale ndlela, ingxaki inokuchongwa ngokulula.

Indlela yokufumanisa isiphaluka esifutshane sesikrini sokubonisa

Isikrini sokubona indlela yokukhangela isiphaluka esifutshane kukuseta i-multimeter kwisixhobo sokukhangela isiphaluka esifutshane, ukuze kubonwe ukuba kukho into emfutshane yesiphaluka.Ukuba isiphaluka esifutshane sifunyenwe, kufuneka sisonjululwe ngokukhawuleza.Isiphaluka esifutshane kwisikrini sokubonisa kwakhona sisona siqhelekileyoImodyuli yokubonisa i-LEDimpazamo.Kwakhona!Ukufumanisa isiphaluka esifutshane kufuneka kuqhutywe xa isiphaluka sivaliwe ukuphepha ukulimaza i-multimeter.

Bonisa indlela yokufumanisa ukuhla kwamandla ombane kwisikrini

Indlela yokubona ukuhla kwamandla ombane kukulungelelanisa i-multimeter kwi-voltage ye-diode ukuze kubonwe i-downshift, kuba zonke ii-ICs kwisikrini sokubonisa zenziwe ngamacandelo amaninzi eyunithi, ngoko xa kukho ukudlula ngoku kwiphini elithile, kuya kubakho ukuhla kwamandla ombane. ephinini.Kwiimeko eziqhelekileyo, i-voltage drop on the IC pins of the model efanayo iyafana.

Ezi ndlela zingentla zokugcinwa kwezikrini ze-LED zingavavanywa ngokungaqhelekanga ukuphepha umonakalo kwisikrini sokubonisa.Oku akwaneli nje ixesha lokusetyenziswa kwayo, kodwa konga iindleko ezingeyomfuneko zohlahlo lwabiwo-mali.Ngenxa yokuba abanye abavelisi besikrini be-LED babonelela kuphela ngenkonzo emva kokuthengisa iminyaka enye ukuya kwemibini, ukuba ukugcinwa kuqhutywe kwakhona emva kweli xesha lenkonzo emva kokuthengisa, kuya kubakho intlawulo eyongezelelweyo.
