Izibane ze-LED ziye zaba sisisombululo sokukhanyisa yonke indawo kumakhaya kunye namashishini, kodwa i-LED yendabuko iye yabhala iintsilelo zabo xa ifika kwimiboniso emikhulu, ephezulu.Iziboniso ze-LEDsebenzisa amandla ombane aphezulu kunye nento ebizwa ngokuba yi-internal power convertion performance iphantsi, nto leyo ethetha ukuba ixabiso lamandla okuqhuba umboniso liphezulu, ubomi bomboniso abukho bude, kwaye bunokubaleka kushushu kakhulu.
Kwiphepha elipapashwe kuPhando lweNano, abaphandi bachaza indlela inkqubela phambili yetekhnoloji ebizwa ngokuba ngamachaphaza e-quantum inokujongana neminye yale mingeni.Amachaphaza e-quantum ziikristale ezincinci ezenziweyo ezisebenza njenge-semiconductors.Ngenxa yobukhulu babo, baneempawu ezizodwa ezinokubenza babe luncedo kwi-teknoloji yokubonisa.
Xing Lin, uprofesa oncedisayo kwisayensi yolwazi kunye nobunjineli be-elektroniki kwiYunivesithi yaseZhejiang, uthe ngokwesikoUmboniso we-LEDbaye baphumelela kwiinkalo ezifana nokubonisa, ukukhanya kunye nonxibelelwano lokukhanya.Nangona kunjalo, ubuchule obusetyenziselwa ukufumana izixhobo ezikumgangatho ophezulu ze-semiconductor kunye nezixhobo zinamandla kakhulu kwaye zixabisa kakhulu.Amachaphaza e-Colloidal quantum anikezela ngendlela enexabiso eliphantsi lokwakha i-LED ephezulu yokusebenza kusetyenziswa iindlela ezingabizi kakhulu zokusetyenzwa kwesisombululo kunye nezixhobo zebakala lekhemikhali.Ngaphaya koko, njengemathiriyeli ye-inorganic, amachaphaza e-colloidal quantum agqitha i-semiconductors ye-organic emissive ngokwemiqathango yozinzo lwexesha elide lokusebenza.
Zonke iziboniso ze-LED zenziwe ngeemaleko ezininzi.Owona maleko ubalulekileyo ngumaleko okhutshwayo, apho amandla ombane ajikwa abe kukukhanya okumibalabala.Abaphandi basebenzise umaleko omnye wamachaphaza e-quantum njengomaleko wokukhupha.Ngokwesiqhelo, umaleko we-colloidal quantum dot emission ngumthombo welahleko yombane ngenxa yokungaqhubi kakuhle kwezinto eziqinileyo ze-colloidal quantum dot.Ngokusebenzisa umaleko omnye wamachaphaza e-quantum njengomaleko okhuphayo, abaphandi baqikelela ukuba banokunciphisa i-voltage ukuya phezulu ukunika amandla ezi ziboniso.
Olunye uphawu lwamachaphaza e-quantum abenza balungele i-LED kukuba banokuveliswa ngaphandle kweziphene ezinokuchaphazela ukusebenza kwabo kakuhle.Amachaphaza e-Quantum anokuyilwa ngaphandle kokungcola kunye neziphene zomhlaba.Ngokutsho kwe-Lin, i-quantum dot LED (i-QLED) inokufezekisa ukuphumelela kokuguqulwa kwamandla angaphakathi kwi-inxinano yangoku efanelekileyo ekuboniseni nasekukhanyiseni izicelo.I-LED eqhelekileyo esekwe kwi-semiconductors ekhule ngokugqithisileyo ibonisa ukusebenza kakuhle kokuqengqeleka ngaphakathi koluhlu loxinaniso lwangoku.IlungeleImboni yokubonisa i-LED.Lo mahluko uvela kwindalo engenasiphene yamachaphaza omgangatho ophezulu we-quantum.
Iindleko eziphantsi kakhulu zokuvelisa iileya ezikhuphayo ezinamachaphaza e-quantum kunye nokukwazi ukusebenzisa ubuchule bobunjineli be-optical ukuphucula ukusebenza kakuhle kokutsalwa kokukhanya kwe-QLED, abaphandi bakrokrela, kunokuphucula ngokufanelekileyo i-LED yemveli esetyenziswa ekukhanyeni, kwimiboniso, kunye nokunye.Kodwa kusekho uphando olongezelelweyo ekufuneka lwenziwe, kwaye i-QLED yangoku ineziphene ekufuneka zoyiswe ngaphambi kokuba zamkelwe ngokubanzi.
Ngokutsho kukaLin, uphando lubonise ukuba amandla ashushu angakhutshwa ukuze kuphuculwe ukusebenza kakuhle kokuguqulwa kwamandla e-electro-optical.Nangona kunjalo, ukusebenza kwesixhobo kweli nqanaba kukude ngokufanelekileyo ngengqiqo yombane osebenzayo ophezulu kunye noxinano oluphantsi lwangoku.Obu buthathaka bunokoyiswa ngokufuna izixhobo zothutho ezingcono kunye nokuyila ujongano phakathi kothutho lwentlawulo kunye neeleya zamachaphaza e-quantum.Injongo ephambili-ukuqonda izixhobo zokupholisa i-electroluminescent-kufuneka zisekelwe kwi-QLED.
