Nakuba ubuchwepheshe be-Micro LED bungasetshenziswa emkhakheni wamadivayisi agqokekayo amancane amelwe i-AR, VR, namawashi ahlakaniphile, zimbalwa kakhulu izinhlelo zokusebenza ezisebenzayo okwamanje.Uma sithatha izibuko ze-AR njengesibonelo, ngokwezibalo ezingaphelele, kuzoba nezinhlobo ezintathu kuphela zezibuko ezisebenzisa ubuchwepheshe be-Micro LED ngo-2022, okuyi-Meta Lens ka-Li Weike, i-Vuzix's Shield kanye nezibuko ezihlakaniphile zika-Tooz's ESSNZ Berlin.
Nakuba inezinzuzo ezisobala kakhulu kunobuchwepheshe be-Micro OLED, indlela eyaIsibonisi esincane se-Micro LEDisicelo abushelelezi.Ekuhlaziyeni kokugcina, inkinga isewukuthi ukuthuthukiswa kobuchwepheshe be-Micro LED kuhamba kancane, inqubo yokukhiqiza ayikavuthwa, izinkinga zezindleko zomkhiqizo, ikhwalithi nokusebenza kahle kwe-chip ukukhanya okubomvu kusekhona, futhi kunzima ukufeza ngokugcwele. -umbala, eduze neso imiphumela yokubonisa ukulungiswa okuphezulu.Isicelo esikhulu emkhakheni we-micro-display.
Noma kunjalo, ngokucwaninga nokuthuthukiswa kobuchwepheshe be-Micro LED, izinkampani ze-LED kanye nezemfundo azikaze zime.Ngokuhlola izixazululo ezihlukene zobuchwepheshe, ubuchwepheshe be-Micro LED buthuthukiswa kancane kancane, futhi inqubo yokufaka i-Micro LED emkhakheni wokuboniswa okuncane iyashesha futhi ibe mfushane.Muva nje, ithimba labacwaningi eliholwa yi-MIT lenze impumelelo entsha ocwaningweni lwesakhiwo esistakiwe esinemibala egcwele i-Micro LED (Stacked RGB Micro LED).Ngokuzayo, lesi sixazululo singaba isici esibalulekile esithinta ukuthuthukiswa kwezinhlelo zokusebenza zesibonisi esincane se-Micro LED.
Ithimba labacwaningi lenze i-Micro LED enombala ogcwele enqwabelene ngokuqondile enokulungiswa okufika ku-5100PPI kanye nosayizi ongu-4μm kuphela.Ithi iyi-Micro LED enohlelo olukhulu lokuminyana nosayizi omncane owaziwayo kuze kube manje.Kuyazuzisa futhi ku-isikrini se-LED esiguquguqukayo.Ukulungiswa okuphezulu nosayizi omncane kakhulu womkhiqizo uhlangabezana nezidingo zohlelo lokusebenza lwemishini kagesi yesibonisi esincane esiseduze neso.
Lo mphumela wocwaningo uphinde wakhuthaza ukuthuthukiswa kanye nokusetshenziswa kwesakhiwo esinqwabelene se-Micro LED, futhi usuphinde wadonsa ukunaka kwemboni ye-LED kulesi sixazululo sobuchwepheshe.Ngokucacile, isici esikhethekile salesi sixazululo ukuthi, uma kuqhathaniswa nephikseli eyodwa eyakhiwe ama-chips e-RGB Micro LED anesakhiwo sokuhlelwa okuhambisanayo kwendabuko, ukusetshenziswa kohlelo lokuhlelwa okupakishiwe kunganciphisa usayizi wemojula yokubonisa ngenkathi kuthuthukiswa ukusebenza kwe- Isibonisi se-Micro LED.
Ikhwalithi nokukhiqiza.Ngokuningiliziwe, isakhiwo esistakiwe senza iphikseli eyodwa ikwazi ukuthatha isikhala esincane, ngakho-ke ukuminyana kwephikseli ephakeme kungafinyelelwa endaweni yeyunithi ngayinye, ngaleyo ndlela kuhlangatshezwane nezidingo zohlelo lokusebenza lwamadivayisi wesibonisi esincane samamojula wokubonisa anosayizi omncane, anencazelo ephezulu.Ngokuphathelene nokukhiqizwa, ngenxa yokusetshenziswa kwesakhiwo esistakiwe, ama-chips e-RGB anemibala emithathu ahlanganiswe ku-chip eyodwa, efinyeza isikhathi sokudlulisa sama-chips e-Micro LED ku-substrate futhi ithuthukise ukunemba kokubekwa, ngaleyo ndlela ithuthukise ukusebenza kahle kokukhiqiza kanye izindleko zezibonisi ze-Micro LED.Ngenxa yokuguqulwa kwesakhiwo, ukukhiqizwa nokusebenzisa i-Micro LED kuzuze amathuba amaningi.
Ngakho-ke, eminyakeni yamuva nje, amabhizinisi asekhaya nakwamanye amazwe, amanyuvesi, nezikhungo zocwaningo ziye zabamba iqhaza ocwaningweni lwesakhiwo esinqwabelene se-Micro LED ukukhuthaza inqubekelaphambili eqhubekayo yalobu buchwepheshe.Ucabangani ngeisikrini se-LED esikhanyayo.Ngokwezibalo ezingaphelele, izinkampani ze-LED zasekhaya nezangaphandle ezifana ne-Seoul Viosys, i-Lumens, i-Sundiode, ne-Nuoshi Technology, kanye nethimba labacwaningi basekhaya lase-Tsinghua University, babambe iqhaza ocwaningweni lwe-Micro LED ehlanganisiwe eminyakeni yamuva.
Ngo-2022, i-Seoul Viosys yabonisa ubuchwepheshe be-WICOP Pixel obunombala ogcwele we-single-chip display.Ama-micro LED chips.Ukusetshenziswa kobuchwepheshe be-WICOP Pixel kunciphisa inqubo yokukhiqiza isibonisi se-Micro LED sibe ingxenye eyodwa kwezintathu, kuthuthukisa izinga lokukhiqiza le-Micro LED, kunciphisa izindleko zokukhiqiza, futhi kunciphisa indawo ekhipha ukukhanya ye-Micro LED kuleyo yemikhiqizo yesakhiwo esikhona. .Okwesithathu, ngemibala emnyama ejulile nezithombe ezibukhali.NgoFebhuwari walo nyaka, i-Seoul Viosys yabonisa isibonisi se-Micro LED esisekelwe kubuchwepheshe be-WICOP Pixel, ngokukhanya okukhuphukele ku-4000nits, okunweba uhla lokusetshenziswa kwe-Micro LED kunkambu ye-Metaverse ehlanganisa i-AR ne-VR.
NgoMeyi 2021, ithimba labacwaningi boMnyango Wezobunjiniyela Bama-elekthronikhi waseNyuvesi yaseTsinghua lakha idizayini ye-Micro LED yedivayisi esekelwe kunqwabelene obomvu, obuluhlaza kanye nohlaza okwesibhakabhaka (RGB).Uma kuqhathaniswa nesakhiwo sedivayisi ye-RGB yehlangothi necele, ngaphansi kosayizi wedivayisi ofanayo, isakhiwo esistakiwe singakhuphula ukulungiswa kwesibonisi izikhathi ezintathu uma kuqhathaniswa nesakhiwo esibheke eceleni, esingathuthukisi kuphela ukusebenza okukhanyayo kwedivayisi. , kodwa futhi kunciphisa ukunemba kokucubungula phakathi nemfuneko yenqubo yokulungiselela.
Kuyabonakala ukuthi eminyakeni yamuva nje, ngocwaningo lwesakhiwo esistakiwe, amabhizinisi namanyuvesi athuthukise ukugqama nokulungiswa kwezibonisi ezincane ze-Micro LED, futhi akhuthaze ukuthuthukiswa kwezibonisi ezincane ezinombala ogcwele we-Micro LED.Ngokubhekana nezinkinga zobuchwepheshe ezikhona ze-Micro LED, isakhiwo esistakiwe sinikeza isisombululo esingaba khona, futhi sivula indlela entsha yobuchwepheshe yokwandisa ukusetshenziswa kobuchwepheshe be-Micro LED ku-AR/VR nokunye.izinkambu zokubonisa ezincane.Kodwa-ke, ngenkathi kuxazululwa izinkinga ezikhona zesakhiwo sendabuko, isisombululo se-Micro LED esihlanganisiwe siletha nobunzima obusha bezobuchwepheshe.
Umkhiqizi wobuchwepheshe be-Micro LED u-Porotech wake waveza ukuthi isakhiwo esistakiwe sisho ukuthi imibala emithathu yokukhanya izokhishwa ezindaweni eziphakeme ezihlukene zesibonisi, okuzokwenza kube nzima ukuklama okubonakalayo, futhi kuthinte nokunemba kwesikhala phakathi kwe-LED nezingqimba ezihlukene. esakhiweni.Ukunemba kokuqondanisa kubeka phambili izidingo eziphakeme.
Nakuba kungekho ukusetshenziswa kwangempela kwemikhiqizo ye-micro-display, izinkampani ezibalulwe ngenhla namanyuvesi anethemba ngobuchwepheshe obunqwabelene, bakholelwa ukuthi isisombululo singasheshisa ukuthuthukiswa kwe-Micro LED ku-AR/VR nakweminye imikhakha.Ngakho-ke, kukholakala ukuthi ucwaningo lwesikhathi esizayo kubuchwepheshe obuhlanganisiwe be-Micro LED ngeke buyeke.Njengoba izinkampani ezihamba phambili ezibulalayo ezifana ne-Apple ne-Samsung ziqhubeka nokwandisa ukwakheka kwazo kubuchwepheshe be-Micro LED, ucwaningo lwezixazululo zobuchwepheshe be-Micro LED okuhlanganisa nezakhiwo ezinqwabelene lungase luthuthuke ngokushesha, lube yingxenye ebalulekile yokuhlola ukuthengiswa kweMicro LED.
