Kwizikrini zokubonisa i-LED, abaninzi abantu bacinga ukuba izinto eziphambili zesikrini, i-LED kunye ne-IC, zinobomi beeyure ze-100,000.Ngokutsho kweentsuku ze-365 / ngonyaka, iiyure ezingama-24 / ukusebenza kwemini, ubomi benkonzo bungaphezulu kweminyaka eyi-11, ngoko ke abaninzi abathengi bakhathalela kuphela ukusebenzisa ii-LED kunye nee-IC ezaziwa kakhulu.Enyanisweni, ezi zimbini ziimeko eziyimfuneko kuphela, kungekhona iimeko ezaneleyo, kuba ukusetyenziswa okunengqiqo kwezibane ezibomvu, eziluhlaza kunye neziluhlaza zibaluleke kakhulu kwisikrini sokubonisa.umboniso uya kubaluleke ngakumbi.Uhlengahlengiso olunengqiqo lwe-IC lukwanceda ukoyisa ingxaki yeentambo ezingenangqiqo zePCB
Imiba ephambili apha yile:
Ekubeni ii-LED kunye nee-ICs zizixhobo ze-semiconductor, zikhetha malunga neemeko zokusetyenziswa kwemo engqongileyo, ngokukhethekileyo malunga ne-25 ° C kwiqondo lobushushu begumbi, kwaye indlela yazo yokusebenza yeyona ilungileyo.Kodwa eneneni, isikrini esikhulu sangaphandle siya kusetyenziswa kwiindawo ezahlukeneyo zobushushu, ezinokuba ngaphezulu kwe-60 ° C ehlotyeni kwaye ngaphantsi kwe-20 ° C ebusika.
Xa umenzi evelisa iimveliso, basebenzisa i-25 ° C njengemeko yovavanyo, kwaye bahlele iimveliso ezahlukeneyo ngokwamabanga.Nangona kunjalo, ezona meko zokusebenza zingu-60°C okanye -20°C.Ngeli xesha, ukusebenza kakuhle kunye nokusebenza kwee-LED kunye nee-ICs azihambelani, kwaye zinokuthi ziqale zibe kwibakala lokuqala.Iya kuba ngamanqanaba amaninzi, ukuqaqamba akuyi kuhambelana, kwaye isikrini se-LED siya kuba mfiliba ngokwendalo.
Oku kungenxa yokuba ukuthomalalisa ukuqaqamba kunye nokuhla kwezibane ezibomvu, eziluhlaza kunye neziluhlaza zahlukile phantsi kweemeko ezahlukeneyo zobushushu.Kwi-25 ° C, ibhalansi emhlophe iyinto eqhelekileyo, kodwa kwi-60 ° C, i-LED yemibala emithathu Ukukhanya kwesikrini kunciphile, kwaye ixabiso layo lokunciphisa alihambisani, ngoko ke isiganeko sokuhla kokukhanya kwesikrini kunye nokufakwa kombala kuya . kwenzeka, kwaye umgangatho wesikrini sonke uya kuncipha.Kwaye kuthekani nge-IC?Uluhlu lobushushu obusebenzayo lwe-IC yi-40℃-85℃.
Iqondo lokushisa ngaphakathi kwebhokisi liyenyuka ngenxa yobushushu obuphezulu bangaphandle.Ukuba iqondo lokushisa ngaphakathi kwebhokisi lidlula i-85 ° C, i-IC iya kusebenza ngokungazinzi ngenxa yokushisa okuphezulu, okanye okwangoku phakathi kwamajelo okanye umahluko phakathi kwee-chips uya kuba mkhulu kakhulu ngenxa yokushisa okuhlukeneyo.kukhokelela eHuaping.
Kwangaxeshanye, unikezelo lwamandla lubaluleke kakhulu.Ngenxa yokuba unikezelo lwamandla lunozinzo oluhlukeneyo lokusebenza, ixabiso le-voltage yemveliso kunye nomthamo womthwalo phantsi kweemeko ezahlukeneyo zokushisa, kuba uxanduva lwenkxaso yenkxaso, amandla ayo enkxaso achaphazela ngokuthe ngqo umgangatho wesikrini.
Uyilo lwebhokisi lubaluleke kakhulu kwisikrini sokubonisa.Ngakolunye uhlangothi, unomsebenzi wokukhusela isiphaluka, ngakolunye uhlangothi, unomsebenzi wokhuseleko, kwaye unomsebenzi wothuli kunye nokungena kwamanzi.Kodwa okona kubaluleke ngakumbi kukuba uyilo lwenkqubo ye-thermal loop yokungenisa umoya kunye nokutshatyalaliswa kobushushu kulungile.Ngokwandiswa kwexesha lokuqalisa kunye nokunyuka kweqondo lokushisa langaphandle, i-thermal drift yamacandelo nayo iya kwanda, ibangele umgangatho ombi womfanekiso.
Ezi zinto zinxulumene zonke kwaye ziya kuchaphazela umgangatho kunye nobomi bomboniso.Ke ngoko, xa umthengi ekhetha isikrini, kufuneka ajonge kwaye ahlalutye ngokucokisekileyo kwaye enze isigwebo esichanekileyo.
