Ngophuhliso oluqhubekayo lweMicroUmboniso we-LED, kuye kwenziwa inkqubela phambili kwezobugcisa.Kutshanje, bekukho uphuhliso olutsha rhoqo kwimiboniso ye-Micro LED, kwaye kubekho iimpumelelo ezininzi zetekhnoloji kwihlabathi.
IYunivesithi yaseYonsei iphuhlisa itekhnoloji yokubonisa i-high-resolution tri-color Micro LED
Kuxelwa ukuba iqela likaNjingalwazi uJong-hyun Ahn weSebe lezoBunjineli boMbane kunye ne-Electronic yeYunivesithi yaseYonsei basebenzisa i-semiconductors ye-MoS2 kunye namachaphaza e-quantum ukuphumeza i-high-resolution tri-color Micro LED display technology.Iteknoloji, epapashwe kwi "Nature Nanotechnology ," kwaye lihlabathi lokuqala ukuphuhlisa iteknoloji ehlanganisiweyo esebenzisa i-semiconductors ene-dimensional semiconductors kunye namachaphaza e-quantum, kulindeleke ukuba isetyenziswe kuphuhliso lwesizukulwana esilandelayo somgangatho ophezulu wokusebenza okwenyani (AR) kunye neziboniso zenyani (VR).Ziindaba ezimnandi zeIshishini le-LED.
Ukwenza isiboniso se-Micro LED, inkqubo entsonkothileyo yokudlulisela iitshiphusi ze-Micro LED ezinemibala emithathu kwibhodi yesekethe ye-backplane iyafuneka.Nangona le ndlela yokuvelisa ifanelekile ukuveliswa kwemiboniso emikhulu kunye nesisombululo esiphantsi, ayikwazi ukuhlangabezana neemfuno zesizukulwana esilandelayo senyani ye-augmented (AR) kunye ne-virtual reality (VR) iziboniso ezifuna ukulungiswa okuphezulu kunye nokusebenza kwesantya esiphezulu.
Ukoyisa imida yobuchwephesha ekuphuhliseni iziboniso zeMicro LED, iqela lophando lenze i-semiconductor molybdenum disulfide (MoS2) ene-dimensional-dimensional semiconductor (MoS2) ngqo kwi-gallium nitride (GaN) wafer yee-LEDs eziluhlaza, emva koko idibanise iisekethe ze-semiconductor ukwenza iisekethe ze-semiconductor nganye , ngempumelelo waqonda yokuqala yehlabathi 500 PPI (inani Micro LED imithombo ukukhanya nge-intshi nganye), high-resolution Micro isiboniso LED ngaphandle inkqubo transfer.Ukongeza, iqela lophando likwaphuhlise ubuchule bokufumana imibala emithathu ephambili ngokuprinta amachaphaza e-quantum kwi-blue GaN Micro LEDs, enokuphucula kakhulu inkqubo yokubonisa kunye nokunciphisa iindleko zemveliso.Ukongeza, itekhnoloji ephuhliswe liqela lophando ayinakuyenza lula inkqubo yokwenziwa kweMicroI-LED ibonisa imveliso, kodwa kwakhona ukufikelela kwisisombululo esiphezulu.
IYunivesithi yaseKyung Hee iphuhlisa uluhlu lwe-optics oluxineneyo lwezixhobo ze-AR
Kutshanje, iqela lophando elikhokelwa nguNjingalwazi uLee Seung-hyun weSebe lobuNjineli bobuNjineli kwiYunivesithi yaseKyung Hee lisebenzise i-ultra-highly edityaniswe kakhulu i-micro-emitting diode (emva koku ebizwa ngokuba zii-Micro LEDs) ukwenza uluhlu lwezinto ezibonakalayo ezinobungakanani bepixel bothuli. amasuntswana kunye namachaphaza e-quantum kunye nombala obalaseleyo.Ukubuyisela.Iireyidi zezinto ezibonakalayo kulindeleke ukuba zisetyenziswe ukwenza iprojekthi yokwenyani yemifanekiso eyongeziweyo kwiliso.I-Fusion inzima ngenxa yokungafani kwi-substrates yokuvelisa i-electronic circuits kunye ne-Micro LEDs.Ngokuqhelekileyo, iisekethe ze-elektroniki zenziwe kwii-silicon substrates, ngelixa ii-Micro LED zenziwe kwi-gallium nitride substrates.Ukusombulula le ngxaki, iqela lophando likaNjingalwazi uLi liphuhlise ubuchule obunokudlulisa umaleko obhityileyo we-gallium nitride, malunga nesinye seshumi sobukhulu beenwele zomntu, kwi-silicon substrate.
Ngokusekwe kobu buchwepheshe, iqela lophando lenze ngempumelelo eyona milinganiselo incinci yehlabathi (5μm) i-pixel ye-LED ngokusebenzisa iteknoloji yesekethe yesilicon kuphela kwaye akukho nkqubo yokubonisa ngokubanzi."Ubuchule bokudlulisa buchatshazelwa kakhulu kukwandiswa kwe-thermal, ngoko ke sigxile ekwenzeni i-alloy layers kumaqondo obushushu aphantsi," wachaza umfundi wobunjineli bombane uShin Yoo-seop.Kwangelo xesha, iqela lophando lasebenzisa itekhnoloji ye-quantum dot ukuphucula izinga lokuzala kombala, ukongeza imvakalelo yokwenyani kwi-AR.Amachaphaza e-Quantum atsale ingqalelo enkulu njengezixhobo ezikhupha ukukhanya kwisizukulwana esilandelayo ngenxa yokucoceka kombala ophezulu kunye nokufotoseka kwefoto xa kuthelekiswa nezinto eziqhelekileyo ezikhupha ukukhanya kuba zinokuveliswa ngokuvelisa ubude obahlukeneyo bamaza okukhanya kwisayizi nganye yamasuntswana ngaphandle kokutshintsha uhlobo.izinto ezinemibala eyahlukeneyo.Nangona kunjalo, amachaphaza e-quantum achaphazeleka kwiintlobo ezahlukeneyo zokunyibilikisa ezisetyenziswa kulungiso lwe-semiconductor ngokubanzi.
Ukusombulula le ngxaki, iqela lophando liphuhlise "indlela yokudlulisa eyomileyo enesisombululo esiphezulu" enokukhetha ipateni ngokwendlela yokuqina kwamandla.Baphumelele ukusebenzisa itekhnoloji ye-quantum dot ukufezekisa umbala we-RGB ngaphandle kwe-solvent.Iipikseli zamehlo eziphuhlisiweyo zincinci kakhulu naxa zijongwa ngemakroskopu, zizenza zilungele izixhobo ezincinci ezifana nezinto ezinxitywayo.Ukongeza, iipikseli ze-optical element ziyakwazi ngokucacileyoiprojekthi ekhokelwayoimifanekiso yokwenyani eyandisiweyo ngokubonisa umbala ophezulu wegamut.
