Ubuchwepheshe bokuboniswa kwesizukulwane esisha okulindeleke kakhulu, i-Micro LED, busetshenziswa kusukela kusayizi omkhulu kuya kosayizi omncane, futhi kusuka endlini kuya ngaphandle.Lezi zikhombisi-ndlela ezimbili ezinkulu zokuthuthukiswa zisathuthuka.Kuze kube manje, izikhungo zocwaningo ezahlukahlukene zisanethemba ngesibikezelo sokukhula senani lemakethe ye-Micro LED.Kungconoisikrini esiholayo esivumelana nezimo.Kodwa-ke, inkinga yezindleko ebambelele endaweni ebalulekile yokuhweba nge-Micro LED isesesigabeni sokuxoxisana nokusebenza phakathi kwamaqembu akhuphuka nomfula.Ngamafuphi, okwamanje asikho isixazululo esisheshayo nesisebenzayo sama-Micro LEDs esisabele kabanzi embonini.
Ngokubona ukuthi i-OLED ithuthukisa izici zokulungisa izinto ngesivinini esisheshayo, ingena ezimakethe zabathengi abaningi bezinto zikagesi nezezimoto.Ngemuva kokuthi i-TFT LCD ene-MiniLED backlight isongelwa, uma iphuzu lesikhathi sokukhiqizwa kwe-Micro LED ngenani elifanele libambezeleka, kungase kube nokunye okuguquguqukayo.Ngokuthuthukiswa kochungechunge lwemboni ye-Micro LED eTaiwan, iChichuang Technology iyingqalabutho yezixazululo zobuchwepheshe.
I-AUO kanye nenkampani esebenzisana nayo iFucai kulindeleke ukuthi ibe nethuba lokuhola ekulandeleni umthamo wokukhiqiza ngobuningi.I-Micro LED ibilokhu imemeza iminyaka eminingi, futhi ekugcineni ingene ngokusemthethweni ekukhiqizeni ngobuningi kulo nyaka.Kulindeleke ukuthi kube nokwehla okukhulu kwamanani nezindleko kulo nyaka, futhi kuzoqhubeka nokwehla eminyakeni embalwa ezayo.Lokhu kuza naphezu kokwehla kwesidingo sama-electronics abathengi kanye nokusetshenziswa kwemali kwebhizinisi phakathi nokwehla kwamandla emali emhlabeni jikelele kanye nokukhuphuka kwezinga lenzalo ngamabhange amakhulu.
Eyokuqala izoba yi-miniaturization yama-Micro LED chips, angase ancishiswe ngokuzayo.Lokhu kusho ukuthi i-epitaxy efanayo ingathola amanye ama-Micro LED chips, futhi izindleko zama-Micro LED chips zizokwehla.Ngaphezu kwalokho, bayanda abakhiqizi bama-chip
ukutshala imali kwiMicroI-LED industry chain, okuphinde kube nomthelela ekuthuthukisweni kwesivuno kanye nokwehliswa kwentengo nezindleko. Okwamanje, kulinganiselwa ukuthi ama-Micro LED chips anethuba lokwehla ngenani lika-30% -40% ngonyaka, elivumela ukusheshisa inqubo yokuhweba.
Ngaphezu kwalokho, kusukela ekuthuthukisweni kwemishini kanye nenqubo, kuya ekuhlanganisweni kwezintambo ezingemuva kanye nokuhlanganiswa kwesistimu, kukhona nendawo yokuthuthukisa ukusebenza kahle kwe-Micro LED nokunciphisa izindleko.Ama-Micro LED okwamanje aqondise izinhlelo zokusebenza ezimbalwa eziqondiwe.Kubandakanya amadivayisi agqokekayo (ikakhulukazi imikhiqizo emisha njengengilazi ye-Metaverse AR), ama-TV anosayizi omkhulu noma izibonisi ezisezingeni eliphezulu, izibonisi zezimoto, njll. Ngokuyinhloko, ama-Micro LED angabekwa kuma-substrates aguquguqukayo, angakha izimo eziningi ezintsha nezimo zokusetshenziswa.Phakathi kwazo, amadivayisi agqokekayo kulindeleke ukuthi abe nemikhiqizo emisha eyengeziwe esebenzisa izibonisi ze-Micro LED ngo-2023.P1.5 Udonga lwevidiyo ye-LED.Kuzophinde kube nemikhiqizo eminingi eyethula imikhiqizo ehlobene.Ukwethulwa kwezibonisi zezimoto kuzothatha isikhathi eside, kodwa i-HUD head-up displays inethuba lokuba uhlelo oluhamba phambili lwe-Micro LED ezinhlelweni zezimoto.
Kuhle ukusho ukuthi ubuchwepheshe be-Micro LED epitaxy.Ngokusebenzisa i-high-energy physics, amafilimu amancane e-GaN ekhwalithi ephezulu angatshalwa ezingeni lokushisa eliphansi, ayishiye ngokuphelele inqubo yokudlulisa abantu abaningi.Izindleko ziyingxenye eyodwa kweshumi kuphela yezibonisi ze-micro-LED ezikhona.Inamandla okukhiqiza ngobuningi, futhi ubuchwepheshe obuhlobene buye bathola amalungelo obunikazi e-Taiwan nase-United States.
Ukudlulisa ngobuningi kuyisinyathelo esibaluleke kakhulu kuzibonisi zanamuhla ze-Micro LED futhi sesithuthuke cishe iminyaka eyishumi.Kodwa iqembu likholelwa ukuthi ukudluliselwa okukhulu kuyindlela engalungile.Ikakhulukazi ngenxa yenqubo yamanje ye-LED whisk whisker flip-chip nezinqubo zokuwohloka kwesakhiwo.Impahla yokukhanya okuluhlaza okwesibhakabhaka i-gallium nitride, kanti okokukhanya okubomvu yi-gallium arsenide.I-voltage yokushayela yezinto ezimbili ihlukile, futhi umjikelezo wokushayela uzodala ubunzima.Ikakhulukazi mayelana nezindleko, inkinga yokukhanda kwe-pixel efile akulula ukuyinqoba, ngakho-ke kunzima ukukhiqiza ngobuningi.
Ngokusebenzisa i-high-energy physics, izinga lokushisa eliphakeme langaphambilini lama-degree angaphezu kuka-1,000 liphuliwe.Amafilimu ekhwalithi ephezulu ye-gallium nitride angatshalwa emazingeni okushisa aphansi, futhi izinga lokushisa lingalawulwa cishe ku-500 kuya ku-700 degrees.Kuhle ngobaisibonisi esiholayo esikhanyayo.Osayizi bephaneli bayatholakala ukusuka kumayintshi angu-2 ukuya kwangu-12 amayintshi.Ingakhuliswa ngemishini yenqubo futhi ihlanganiswe nokuhlaziywa kwedatha enkulu ukuze uthole imodi ye-epitaxial engcono kakhulu.Ipuleti layo le-epitaxial elizithuthukisele, elihlanganiswe nobuchwepheshe be-nanomaterial, lingafinyelela umphumela wokubonisa we-micro-LED onemibala egcwele.Izindleko zephaneli eyodwa ziyingxenye eyodwa kweshumi kuphela yaleyo ekhona, futhi inamandla amakhulu okukhiqiza ngobuningi.
