Izibani ze-LED seziphenduke isixazululo sokukhanyisa yonke indawo yamakhaya namabhizinisi, kodwa i-LED yendabuko ibhale phansi ukushiyeka kwayo uma kuziwa ekuboniseni okukhulu, okuphezulu.Izibonisi ze-LEDsebenzisa ama-voltage aphezulu kanye nento ebizwa ngokuthi ukusebenza kahle kokuguqulwa kwamandla angaphakathi iphansi, okusho ukuthi izindleko zamandla okusebenzisa isibonisi ziphezulu, impilo yesibonisi ayinde, futhi ingasebenza ishise kakhulu.
Ephepheni elishicilelwe ku-Nano Research, abacwaningi baveza ukuthi intuthuko yezobuchwepheshe ebizwa ngokuthi amachashazi e-quantum ingabhekana kanjani nezinye zalezi zinselelo.Amachashazi e-Quantum amakristalu okwenziwa amancane asebenza njengama-semiconductors.Ngenxa yobukhulu bazo, banezinto ezihlukile ezingabenza basebenziseke kubuchwepheshe bokubonisa.
UXing Lin, umsizi kaprofesa wesayensi yolwazi nobunjiniyela be-elekthronikhi eNyuvesi yaseZhejiang, uthe ngokwesikoIsibonisi se-LEDbaye baphumelela emikhakheni efana nokubonisa, ukukhanyisa kanye nokuxhumana okubonakalayo.Kodwa-ke, amasu asetshenziselwa ukuthola izinto ezisezingeni eliphezulu ze-semiconductor namadivayisi adinga amandla kakhulu futhi abiza kakhulu.Amachashazi e-Colloidal quantum anikezela ngendlela engabizi kakhulu yokwakha i-LED esebenza kahle usebenzisa amasu okucubungula isixazululo angabizi nezinto ezisezingeni lamakhemikhali.Ngaphezu kwalokho, njengezisetshenziswa ze-inorganic, amachashazi e-colloidal quantum adlula ama-semiconductors ezinto eziphilayo ngokuzinza kokusebenza kwesikhathi eside.
Zonke izibonisi ze-LED zakhiwe izendlalelo eziningi.Esinye sezingqimba ezibaluleke kakhulu ungqimba olukhipha umoya, lapho amandla kagesi eguqulwa abe ukukhanya okumibalabala.Abacwaningi basebenzise isendlalelo esisodwa samachashazi e-quantum njengesendlalelo esikhiphayo.Ngokuvamile, ungqimba olukhipha amachashazi e-colloidal quantum luwumthombo wokulahleka kwamandla kagesi ngenxa yokungaqhubeki kahle kwezinto eziqinile zechashazi le-quantum.Ngokusebenzisa ungqimba olulodwa lwamachashazi e-quantum njengongqimba olukhipha umoya, abacwaningi bacabanga ukuthi bangehlisa i-voltage ibe phezulu ukuze banike amandla lezi zibonisi.
Esinye isici samachashazi e-quantum awenza alungele i-LED ukuthi angenziwa ngaphandle kokulimala okungathinta ukusebenza kahle kwawo.Amachashazi e-Quantum angaklanywa ngaphandle kokungcola kanye nokulimala kwendawo.Ngokuka-Lin, i-quantum dot LED (QLED) ingafinyelela ukusebenza kahle kokuguqulwa kwamandla angaphakathi aseduze nobunye ekuminyanisweni kwamanje okufanele ukuboniswa nokukhanyisa izinhlelo zokusebenza.I-LED evamile esekelwe kuma-semiconductors asekhulile abonisa ukusebenza kahle okukhulu phakathi kwebanga elifanayo lamanje lokuminyana.IlungeleImboni yokubonisa i-LED.Lo mehluko usukela kumvelo engenasici yamachashazi ekhwalithi ephezulu we-quantum.
Izindleko eziphansi kakhulu zokukhiqiza izendlalelo ezikhishwayo ezinamachashazi e-quantum kanye nekhono lokusebenzisa amasu onjiniyela obonakalayo ukuze kuthuthukiswe ukusebenza kahle kokukhipha ukukhanya kwe-QLED, abacwaningi basola ukuthi, zingathuthukisa ngempumelelo i-LED yendabuko esetshenziswa ekukhanyeni, ezibukweni, nokunye okwengeziwe.Kodwa kusenocwaningo olwengeziwe okufanele lwenziwe, futhi i-QLED yamanje inokushiyeka okuthile okudingeka kunqotshwe ngaphambi kokuba kwamukelwe kabanzi.
Ngokusho kukaLin, ucwaningo luye lwabonisa ukuthi amandla ashisayo angakhishwa ukuze kuthuthukiswe ukusebenza kahle kokuguqulwa kwamandla e-electro-optical.Kodwa-ke, ukusebenza kwedivayisi kulesi sigaba kusekude nokuhle ngomqondo wama-voltage okusebenza aphezulu uma kuqhathaniswa nokuminyana kwamanje.Lobu buthakathaka bunganqotshwa ngokufuna izinto zokuhamba ezishaja kangcono kanye nokuklama ukuxhumana phakathi kokuthutha okushaja nezendlalelo zamachashazi e-quantum.Umgomo omkhulu—ukubona amadivaysi okupholisa ama-electroluminescent—kufanele asekelwe ku-QLED.
