Ezikrinini zokubonisa ze-LED, abantu abaningi bacabanga ukuthi izinto eziyinhloko zesikrini, i-LED ne-IC, zinesikhathi sokuphila samahora angu-100,000.Ngokwezinsuku ezingama-365/ngonyaka, ukusebenza kwamahora angama-24/ngosuku, impilo yesevisi ingaphezu kweminyaka eyi-11, ngakho-ke amakhasimende amaningi akhathalela kuphela ukusebenzisa ama-LED nama-IC awaziwayo.Eqinisweni, lezi ezimbili ziyizimo ezidingekayo kuphela, hhayi izimo ezanele, ngoba ukusetshenziswa okunengqondo kwezibani ezibomvu, eziluhlaza okwesibhakabhaka nokuluhlaza okwesibhakabhaka kubaluleke kakhulu esikrinini sokubonisa.ukubonisa kuzoba okubaluleke kakhulu.Ukulungiswa okunengqondo kwe-IC kusiza futhi ukunqoba inkinga yezintambo ezingenangqondo ze-PCB
Izici ezibalulekile lapha yilezi:
Njengoba ama-LED nama-IC kungamadivayisi e-semiconductor, ayakhetha mayelana nezimo zokusebenzisa indawo ezungezile, okungcono azungeze u-25°C ekamelweni lokushisa, futhi indlela yawo yokusebenza ihamba phambili.Kodwa empeleni, isikrini esikhulu sangaphandle sizosetshenziswa ezindaweni ezihlukene zokushisa, okungenzeka zibe ngaphezu kuka-60°C ehlobo nangaphansi kuka-20°C ebusika.
Uma umkhiqizi ekhiqiza imikhiqizo, basebenzisa u-25°C njengesimo sokuhlola, futhi bahlukanise imikhiqizo ehlukene ngokwezigaba.Nokho, izimo zokusebenza zangempela zingu-60°C noma -20°C.Ngalesi sikhathi, ukusebenza kahle nokusebenza kwama-LED nama-IC akuhambisani, futhi kungenzeka kwasekuqaleni abe ngelebanga lokuqala.Izoba ngamaleveli amaningi, ukukhanya kuzohluka, futhi isikrini se-LED sizofiphalisa ngokwemvelo.
Lokhu kungenxa yokuthi ukuncishiswa kokukhanya nokwehla kwezibani ezibomvu, eziluhlaza neziluhlaza okwesibhakabhaka kuhlukile ngaphansi kwezimo zokushisa ezihlukene.Ku-25°C, ibhalansi emhlophe ijwayelekile, kodwa ku-60°C, i-LED yemibala emithathu Ukukhanya kwesikrini kwehlile, futhi inani laso lokunciphisa alihambisani, ngakho-ke ukwenzeka kwakho konke ukukhanya kwesikrini kuyehla kanye nokufakwa kombala. kwenzeka, futhi ikhwalithi yesikrini sonke izokwehla.Futhi kuthiwani nge-IC?Izinga lokushisa elisebenzayo le-IC ngu -40℃-85℃.
Izinga lokushisa ngaphakathi kwebhokisi liyakhuphuka ngenxa yezinga lokushisa eliphezulu langaphandle.Uma izinga lokushisa ngaphakathi kwebhokisi lingaphezu kuka-85°C, i-IC izosebenza ingazinzile ngenxa yezinga lokushisa eliphezulu, noma i-current phakathi kwamashaneli noma umehluko phakathi kwama-chips uzoba mkhulu kakhulu ngenxa yokukhukhuleka okuhlukile kwezinga lokushisa.kuholela eHuaping.
Ngesikhathi esifanayo, ukunikezwa kwamandla nakho kubaluleke kakhulu.Ngenxa yokuthi ugesi unokuzinza okuhlukile kokusebenza, inani le-voltage ephumayo kanye nomthamo wokulayisha ngaphansi kwezimo ezihlukene zokushisa, ngenxa yokuthi unesibopho sokusekelwa kwezinto, ikhono lakho lokusekela lithinta ngokuqondile ikhwalithi yesikrini.
Ukwakheka kwebhokisi nakho kubaluleke kakhulu esikrinini sokubonisa.Ngakolunye uhlangothi, inomsebenzi wokuvikela isifunda, ngakolunye uhlangothi, inomsebenzi wokuphepha, futhi inomsebenzi wokuvikela uthuli nokungenamanzi.Kodwa okubaluleke kakhulu ukuthi ngabe ukuklanywa kwesistimu ye-loop eshisayo yokukhipha umoya kanye nokukhipha ukushisa kuhle.Ngokunwetshwa kwesikhathi sokuqalisa kanye nokwenyuka kwezinga lokushisa langaphandle, ukukhukhuleka okushisayo kwezingxenye nakho kuzokwanda, okubangele ikhwalithi yesithombe empofu.
Lezi zici zonke zihlobene futhi zizothinta ikhwalithi nempilo yesibonisi.Ngakho-ke, lapho ikhasimende likhetha isikrini, kufanele futhi libheke futhi lihlaziye ngokucophelela futhi lenze isinqumo esifanele.
