I-Micro LED ithathwa njengesixazululo "sokuboniswa kokugcina", futhi amathuba okusebenza kwayo kanye nenani engalidala kukhanga ngokwedlulele.Amathuba ohlelo olusha olufana nezibonisi zentengiso, ama-TV asezingeni eliphezulu, izimoto namadivayisi agqokekayo ayaqhubeka nokuzuza ukuthuthukiswa okunamandla, nezimboni ezihlobene ezikhuphukayo nezingaphansi komfula zilolonga kabusha i-ecosystem yesibonisi.
Ingilazi-basedIzibonisi ze-Micro LEDzinokusebenza okuhle kakhulu nemisebenzi eguquguqukayo, futhi kulindeleke ukuthi zisetshenziswe kabanzi emibukisweni yezentengiselwano, ama-TV asezingeni eliphezulu, izimoto, nezinto ezigqokwayo, ezinamandla amakhulu emakethe.Ukwengeza amathuluzi amasha nezinto zokwakha kuzoba yithuba elibalulekile lokuthuthukiswa kwezimboni, futhi kulindeleke ukuthi kubunjwe kabusha i-ecosystem yemboni.I-Micro LED ingabona izinhlelo zokusebenza zokuhlanganisa zamahhala ezinosayizi omkhulu, futhi ubuchwepheshe obufana nokupakishwa kwemodular kanye nezintambo eziseceleni kwenza ukuhlanganisa kwamahhala kwenzeke.I-Micro LED ingakwazi futhi ukubona ukusetshenziswa kokuhlanganiswa kwedivayisi okusebenzisanayo.Isikrini sesikhathi esizayo kulindeleke ukuthi sibe inkundla, engakwazi ukubona imisebenzi ehlukahlukene njengokuxhumana ngezinzwa, futhi iphule umqondo "wesibonisi".
Ukuqamba okusha ezingeni ledivayisi kungaletha uguquko ezingeni lokusebenza.Ngokuboniswa kwe-3D, ukusebenzisana kwe-3D, nobuchwepheshe obuvelayo obufana ne-5G nedatha enkulu, ukuqondiswa kokuthuthukiswa kwesibonisi se-holographic esikhathini esizayo akungabazeki ukuthi kuyajabulisa.I-Micro LED esekwe kungilazi ingamboza izinkambu zokusetshenziswa zemikhiqizo emikhulu, emaphakathi kanye nencane.Usayizi wemakethe kulindeleke ukuthi ukhule ngokushesha kusukela ngo-2024, futhi kulindeleke ukuthi wakhe uchungechunge olusha lwezimboni olukhuphuka nolwehla nomfula.
Ngemva kweminyaka yocwaningo nentuthuko, isibonisi esikhulu se-Micro LED sesifinyelele ngokusemthethweni ingqopha-mlando ekukhiqizweni ngobuningi kulo nyaka, futhi isibe amandla ashukumisayo ekuthuthukisweni kwezingxenye ezihlobene, amathuluzi nezinqubo zokukhiqiza.Ukwengezwa kwabakhiqizi abaningi kanye nenkambiso eqhubekayo yokuthuthuka ye-miniaturization kwenze ukuthiImboni ye-Micro LEDukuzuza ngokuqhubekayo impumelelo emisha yezobuchwepheshe, futhi izinga lemakethe nalo liqhubekile nokukhula.
Ngaphezu kwezibonisi ezinkulu, i-Micro LED inezici ezinhle kakhulu ezingasetshenziswa ngezindiza ezishintshayo nezingena ngaphakathi.Ingavela ekubonisweni kwezimoto nasekuboniseni okugqokekayo, idale ithuba elisha lohlelo lokusebenza elihlukile kubuchwepheshe bamanje bokubonisa.Ukungena kwabakhiqizi abaningi kanye nenkambiso yentuthuko ye-miniaturization eqhubekayo kuzoba ukhiye wokwehliswa okuqhubekayo kwezindleko ze-chip.
Izibonisi zesikhathi esizayo kufanele zikwazi ukukhulula izandla, futhi zigxilise imisebenzi eminingi esikrinini ukuze kuzuzwe ukusebenzisana.Lokhu kudinga ukuthi isibonisi kufanele sibe nokugqama okuphezulu, i-PPI ephezulu, ukukhanya okuphezulu, kanye neqiniso elinwetshiwe.Njengamanje, i-Micro LED ingahlangabezana nezidingo zentuthuko yemboni yokubonisa yesikhathi esizayo, kodwa inqubo yokwenziwa kwezimboni isadinga ukusheshisa.Ngokuvamile, ukwenziwa kwezimboni kwe-Micro LED kumele kuqale kubone ukukhiqizwa kwenqwaba yama-chips kanye nokwenza kahle okuqhubekayo kokusebenza.Okwesibili, ukudluliswa kwenqwaba kudinga ukuhlanganiswa nokulungisa ukuze kuzuzwe ukukhiqizwa ngobuningi bemikhiqizo.Okwesithathu, ngaphansi kwesimo sokushayela i-micro-current, ukusebenza kahle kokukhiqizwa kwe-Micro LED kudinga ukuthuthukiswa okwengeziwe.Okokugcina, imvelo yezimboni isakhiwa, futhi izindleko zehardware zidinga ukuqhubeka nokwehla.
Imboni kufanele icabangele indlela yokuthuthukisa ukukhiqizwa kwe-Micro LED, okuhlanganisa ukulungisa.Kunamashumi ezigidi zama-LED ku-TV.Uma zidluliselwa ku-substrate, ngisho noma izinga lokukhiqiza lingafinyelela ku-99.99%, kusenezindawo eziningi ezidinga ukulungiswa ekugcineni, futhi kuzothatha isikhathi eside.Kuphinde kube nenkinga yokukhanya okungalingani esibukweni.Ngaphezu kwalokho, mayelana nesivinini sokukhiqiza ngobuningi, izinga lokukhiqiza kanye nezindleko, i-Micro LED ayinazo izinzuzo uma iqhathaniswa nekristalu ewuketshezi yamanje ekhulile kakhulu.Nakuba imboni yenze umsebenzi omningi ekudluliseleni abantu abaningi, iMicro LED isenendlela ende okufanele ihanjwe ngaphambi kokuba ifinyelele ukukhiqizwa ngobuningi.Kunezindlela ezimbili eziyinhloko zokudlulisa abantu abaningi, eyodwa i-Pick&Place, kanti enye i-laser mass transfer.
Ngemuva kokuboniswa kwekristalu ewuketshezi, i-Micro LED iyimbangi eqinile yesizukulwane esisha sobuchwepheshe be-iteration, futhi i-Micro LED chip ngokungangabazeki iyisixhumanisi esiyinhloko.Kuyaqondakala ukuthi usayizi we-Micro LED uyiphesenti elilodwa kuphela le-chip ye-LED evamile, efinyelela ukuhleleka kwamashumi ama-microns.
Kusukela ku-LED kuya ku-Mini LED, awukho umehluko omkhulu kubuchwepheshe be-chip kanye nenqubo ye-chip empeleni, kodwa usayizi we-chip uyashintsha.Ushintsho olubalulekile ekuthuthukisweni kwe-Micro LED ukuthi ukuhlukaniswa kwe-chip akukwazi ukuqedelwa ngokuphungula nokubhala i-sapphire substrate, kodwa i-chip ye-GaN kufanele ihlulwe ku-substrate yesafire ngokuqondile.Ubuchwepheshe obukhona buyi-laser lift-off kuphela, yona ngokwayo inqubo ebhubhisayo, engavuthiwe kakhulu e-China.Lena inkinga yokuqala i-chip ebhekene nayo.
Inkinga yesibili ukuminyana kwe-Dislocation ye-Micro LED chip, enomthelela omkhulu kakhulu ekuhambisaneni kwe-Micro LED chip.Ekuqaleni, ukuminyana kwe-dislocation ku-GaN LED epitaxy kwakuphezulu njengo-1010. Nakuba ukuminyana kokususwa kwakuphezulu, ukusebenza kahle okukhanyayo nakho kwakuphezulu.Ngemuva kokuthi i-gallium nitride LED ikhiqizwa eJapane, ngemva kweminyaka engaphezu kwengu-30 yentuthuko, ukuthuthukiswa kwenqubo sekufinyelele ophahleni, futhi ukuminyana kwe-dislocation sekufinyelele ku-5 × 108.Kodwa-ke, ngenxa yokuminyana okuphezulu kokugudluka kobuchwepheshe be-LED obukhona, ukuthuthukiswa kweMicro LED kungase kukhawule kakhulu ukuthuthukiswa kwemikhiqizo elandelayo.Ngakho-ke, ukuqhubeka nobuchwepheshe obukhona be-chip ye-LED nokuthuthukisa i-Micro LED kudinga ukuxazulula izinkinga ezimbili.Enye iwukuqhubeka nokunciphisa ukuminyana kokugudluka kwezinto ze-gallium nitride, kanti enye iwukuthola ubuchwepheshe obungcono bokuphakamisa kunobuchwepheshe be-laser lift-off.
