Namhlanje,Ukubonisa irenti ye-LEDzisetyenziswe ngokubanzi kwiinkalo ezahlukeneyo.Banokusebenzisa isiphumo esibanzi semathiriyeli ye-high-tech kunye nobuchwepheshe ukubonisa ngokucacileyo imixholo yentengiso kunye nokutsala abaphulaphuli abanempembelelo ebonakalayo ebonakalayo.Ngoko ke, Ikho kuyo yonke indawo ebomini.Nangona kunjalo, njengemveliso yezixhobo zombane, ubomi benkonzo yokubonisa irenti ye-LED ngomnye wemiba esiyixhalabele kakhulu.Ke ngaba uyazi ukuba zeziphi izizathu ezichaphazela ubomi beIzikrini zokurenta ze-LED?
Izizathu ezichaphazela ubomi bezikrini zokurenta ze-LED zezi zilandelayo:
1. Ubushushu
Izinga lokungaphumeleli kwayo nayiphi na imveliso liphantsi kakhulu ngaphakathi kobomi bayo benkonzo kwaye kuphela phantsi kweemeko ezifanelekileyo zokusebenza.Njengemveliso yombane ehlanganisiweyo,Izikrini zokurenta ze-LEDubukhulu becala iqulathe iibhodi zolawulo kunye namacandelo elektroniki, ukutshintsha izixhobo amandla, izixhobo ukukhanya-emitting, njl ukubunjwa, kunye nobomi zonke ezi ngokusondeleyo ezinxulumene ubushushu yokusebenza.Ukuba iqondo lokushisa langempela lokusebenza lidlula uluhlu oluchaziweyo lokusetyenziswa kwemveliso, kungekhona nje ukuba ubomi benkonzo bufutshane, kodwa imveliso ngokwayo iya konakala kakhulu.
2. Uthuli
Ukuze ukwandise ubomi obuqhelekileyo besikrini sokurenta se-LED, isoyikiso sothuli asinakuhoywa.Xa usebenza kwindawo enothuli, ibhodi eprintiweyo ifunxa uthuli, kwaye i-deposition yothuli iya kuchaphazela ukutshatyalaliswa kobushushu bamacandelo e-elektroniki, okuya kubangela ukuba ubushushu bamacandelo buphakame, kwaye ke ukuzinza kwe-thermal kuya kuncipha kwaye kunye nokuvuza kuya kwenzeka.Kwiimeko ezinzima, kuya kubangela ukudinwa.Ukongeza, uthuli luya kutsala ukufuma, ludle iisekethe ze-elektroniki, kwaye lubangele ukusilela kwisekethe emfutshane.Nangona uthuli luncinci ngobukhulu, umonakalo walo kwiimveliso awukwazi ukujongelwa phantsi.Ngoko ke, ukucoca rhoqo kuyimfuneko ukunciphisa amathuba okungaphumeleli.
3. Ukufuma
Nangona phantse zonke izikrini zokurenta ze-LED zinokusebenza ngokuqhelekileyo kwindawo enomswakama we-95%, ukufuma kuseyinto ebalulekileyo echaphazela ubomi bemveliso.Irhasi yomswakama iya kungena ngaphakathi kwesixhobo se-IC ngokusebenzisa indawo edibeneyo yezinto zokupakisha kunye namacandelo, okubangela i-oxidation, i-corrosion, kunye nokuqhawulwa kwesekethe yangaphakathi.Ukushisa okuphezulu ngexesha lendibano kunye nenkqubo ye-welding kuya kubangela ukuba igesi yokufuma engena kwi-IC yandise kwaye ivelise uxinzelelo, okubangela ukuba iplastiki iqhube.Ukwahlula kwangaphakathi (i-delamination) kwi-chip okanye isakhelo esikhokelayo, ukonakala kocingo, ukonakala kwetshiphu, iintanda zangaphakathi kunye neentanda eziya kufikelela kumphezulu wecandelo, kunye nokugqabhuka kwecandelo kunye nokugqabhuka, okukwabizwa ngokuba yi "popcorning", kuya kubangela ukusilela kwindibano.Amalungu asenokulungiswa okanye acinywe.Okubaluleke ngakumbi kukuba iziphene ezingabonakaliyo kunye nezinokwenzeka ziya kuhlanganiswa kwimveliso, kubangela iingxaki ngokuthembeka kwemveliso.
4. Umthwalo
Ingaba i-chip edibeneyo, i-tube ye-LED, okanye i-switching power supply, ingaba isebenza phantsi komthwalo olinganisiweyo okanye cha, umthwalo uyinto ebalulekileyo echaphazela ubomi bayo.Ngenxa yokuba naliphi na icandelo linexesha lomonakalo wokudinwa, ukuthatha unikezelo lwamandla njengomzekelo, unikezelo lwamandla oluphawulwe lunokuvelisa i-105% ukuya kwi-135% yamandla.Nangona kunjalo, ukuba unikezelo lwamandla lusebenza phantsi komthwalo ophezulu ixesha elide, ukuguga kokunikezelwa kwamandla okutshintsha ngokuqinisekileyo kuya kukhawuleziswa.Ewe kunjalo, umbane otshintshayo unokungaphumeleli kwangoko, kodwa uya kunciphisa ngokukhawuleza ubomi besikrini sokurenta se-LED.
Isishwankathelo, nazi ezinye zezizathu ezichaphazela ubomi bezikrini zokurenta ze-LED.Yonke into yokusingqongileyo efunyanwa sisikrini serenti ye-LED ngexesha lomjikelo wobomi ifuna ukuqwalaselwa ngexesha lenkqubo yoyilo, ukuze kuqinisekiswe ukuba ukuqina okwaneleyo kokusingqongileyo kubandakanyiwe kuyilo lokuthembeka.Ngokuqinisekileyo, ukuphucula imeko yokusetyenziswa kwesikrini sokurenta i-LED kunye nokugcinwa rhoqo kwemveliso akunakuphelisa kuphela iingozi ezifihliweyo kunye neempazamo ngexesha, kodwa kunokunceda ukuphucula ukuthembeka kwemveliso kunye nokwandisa ubomi obuqhelekileyo besikrini sokurenta se-LED.
