Ngokuthuthuka okuqhubekayo kweMicroIsibonisi se-LED, kuningi okuthuthukile okwenziwe kwezobuchwepheshe.Muva nje, kube nentuthuko emisha kaningi kuzibonisi ze-Micro LED, futhi kube nokuthuthuka okuningi okusha kwezobuchwepheshe emhlabeni.
I-Yonsei University ithuthukisa ubuchwepheshe bokubonisa obune-high-resolution tri-color Micro LED display
Kubikwa ukuthi ithimba likaSolwazi Jong-hyun Ahn woMnyango Wezobunjiniyela Bezogesi Nobuchwepheshe beNyuvesi yase-Yonsei lasebenzisa ama-semiconductors e-MoS2 namachashazi e-quantum ukuze kuzuzwe ubuchwepheshe bokubonisa obuthathu obune-Micro LED obunesinqumo esiphezulu.Ubuchwepheshe, obushicilelwe ku-"Nature Nanotechnology ," futhi ingeyokuqala emhlabeni ukuthuthukisa ubuchwepheshe obudidiyelwe obusebenzisa amasemiconductors anezinhlangothi ezimbili namachashazi e-quantum, okulindeleke ukuthi kusetshenziswe ekuthuthukisweni kwezibonisi zesizukulwane esilandelayo se-high-performance augmented reality (AR) kanye nezibonisi ze-virtual reality (VR).Kuyizindaba ezinhleImboni ye-LED.
Ukuze wenze isibonisi se-Micro LED, inqubo eyinkimbinkimbi yokudlulisa ngawodwana ama-chips ama-Micro LED anemibala emithathu ebhodini lesekethe elingemuva liyadingeka.Nakuba le ndlela yokukhiqiza ifaneleka ukukhiqizwa kwezibonisi ezinkulu ezinokulungiswa okuphansi, ayikwazi ukuhlangabezana nezidingo zesizukulwane esilandelayo esingathandwa kwabathelisi esikubona (AR) kanye nezibonisi zangempela (VR) ezidinga ukulungiswa okuphezulu nokusebenza ngesivinini esikhulu.
Ukuze kunqotshwe ukulinganiselwa kobuchwepheshe bokuthuthukisa izibonisi ze-Micro LED, ithimba labacwaningi lenze i-semiconductor molybdenum disulfide (MoS2) enezinhlangothi ezimbili ngqo ku-wafer ye-gallium nitride (GaN) yama-LED aluhlaza, lase lihlanganisa amasekhethi e-semiconductor ukuze kwakheke amasekhethi e-semiconductor ngamanye , ibone ngempumelelo i-PPI yokuqala engu-500 emhlabeni (inombolo yemithombo yokukhanya ye-Micro LED iyintshi ngayinye), isibonisi se-Micro LED esinokulungiswa okuphezulu ngaphandle kwenqubo yokudlulisa.Ngaphezu kwalokho, ithimba locwaningo lithuthukise nendlela yokuzuza imibala emithathu eyinhloko ngokuphrinta amachashazi e-quantum kuma-LED aluhlaza we-GaN Micro, okungathuthukisa kakhulu inqubo yesibonisi futhi kunciphise izindleko zokukhiqiza.Ngaphezu kwalokho, ubuchwepheshe obuthuthukiswe ithimba labacwaningi abukwazi nje ukwenza lula inqubo yokukhiqiza eyinkimbinkimbi ye-MicroI-LED ibonisa umkhiqizo, kodwa futhi uzuze ukulungiswa okuphezulu.
I-Kyung Hee University yakha i-ultra-dense optics yamadivayisi we-AR
Muva nje, ithimba labacwaningi eliholwa uSolwazi u-Lee Seung-hyun woMnyango Wezobunjiniyela Bama-elekthronikhi eNyuvesi yase-Kyung Hee lisebenzisa ama-micro-emitting diode adidiyelwe kakhulu (ngemuva kwalokhu okubizwa ngokuthi ama-Micro LEDs) ukuze lenze ama-optical element anosayizi wamaphikiseli othuli. izinhlayiya namachashazi e-quantum nombala omuhle kakhulu.Ukubuyisela.Ukuhlelwa kwezinto ezibonakalayo kulindeleke ukuthi kusetshenziselwe ukuveza izithombe ezingokoqobo ezingathandwa kwabathelisi esikubona esweni.I-Fusion inzima ngenxa yomehluko kuma-substrates okukhiqiza amasekethe kagesi nama-Micro LED.Imvamisa, amasekethe kagesi enziwa kuma-silicon substrates, kuyilapho ama-Micro LED enziwa kuma-gallium nitride substrates.Ukuze kuxazululwe le nkinga, iqembu locwaningo likaProfessor Li lakha indlela engadlulisa izingqimba ezincanyana ze-gallium nitride, cishe ingxenye eyodwa kweshumi yogqinsi lwezinwele zomuntu, iwufake endaweni engaphansi ye-silicon.
Ngokusekelwe kulobu buchwepheshe, ithimba labacwaningi lenze ngempumelelo usayizi wezinhlayiyana ze-LED ezincane kunazo zonke emhlabeni (5μm) ngokusebenzisa ubuchwepheshe besekethe ye-silicon kuphela futhi akukho nqubo yokubonisa evamile."Isu lokudlulisa lithinteka kakhulu ekunwebeni okushisayo, ngakho-ke sigxile ekwenzeni izendlalelo zengxubevange emincane emazingeni okushisa aphansi," kuchaza umfundi wobunjiniyela kagesi uShin Yoo-seop.Ngesikhathi esifanayo, ithimba locwaningo lasebenzisa ubuchwepheshe bechashazi le-quantum ukuze lithuthukise izinga lokuzala kombala, lengeze umuzwa wamaqiniso ku-AR.Amachashazi e-Quantum adonse ukunaka okukhulu njengamadivayisi esizukulwane esilandelayo akhipha ukukhanya ngenxa yokuhlanzeka kwawo okuphezulu kombala kanye nokuthatha izithombe uma kuqhathaniswa nezinto ezivamile ezikhipha ukukhanya ngoba angakhiqizwa ngokukhiqiza ubude obuhlukahlukene bamaza okukhanya kusayizi wezinhlayiyana ngayinye ngaphandle kokushintsha uhlobo.izinto ezinemibala ehlukahlukene.Kodwa-ke, amachashazi e-quantum angenwa kalula yizincibilikisi ezihlukahlukene ezisetshenziswa ekucubunguleni okujwayelekile kwe-semiconductor.
Ukuze kuxazululwe le nkinga, ithimba labacwaningi lenze "indlela yokudlulisa okomile enesinqumo esiphezulu" engakhetha ngokukhetha ngokuya ngobukhulu bamandla angaphezulu.Baphumelele ukusebenzisa ubuchwepheshe be-quantum dot ukuthola umbala we-RGB ngaphandle kwe-solvent.Amaphikseli okukhanya athuthukisiwe mancane kakhulu ngisho noma ebhekwa ngesibonakhulu, awenza afanelekele izinto ezincane ezifana nezinto ezigqokwayo.Ngaphezu kwalokho, amaphikseli we-optical element angakwazi ngokucacileiphrojekthi eholelekileizithombe ezingokoqobo ezingathandwa kwabathelisi esikubona ngokubonisa i-gamut yombala ophezulu.
