Ubuchwepheshe bokubonisa besizukulwane esilandelayo iMicro LED sekuyiyona nto okugxilwe kuyo kakhulu kulo nyaka weTouch Taiwan Smart Display Exhibition.Ngokuvulwa konyaka wokuqala we-Micro LED ngonyaka odlule, abakhiqizi abakhulu babonise izimo eziningi zokulingisa kanye nezicelo ezibheke phambili kulo nyaka, futhi u-2022 ngokungangabazeki uzoba unyaka obalulekile ngemuva kokuqala.Ngokuthuthuka okuqhubekayo kobuchwepheshe, abakhiqizi be-Micro LED baye bawela kancane kancane izintaba ezimbili "zezindleko" kanye "nesivuno", futhi babhekene "nomkhathizwe omusha" emehlweni e-Micro LED.
Inqubo ye-Micro LED ihlukaniswe ikakhulukazi ekukhuleni kwe-chip, ukukhiqizwa kwama-chip, inqubo yefilimu emincane, ukudluliswa kobuningi, ukuhlolwa nokukhanda.Ngenxa yokususwa kwephakeji ye-LED ne-substrate, okushiya ifilimu ye-epitaxial, i-Micro LED chip ilula, incane futhi ifushane, ihlinzeka ngamasayizi amaphikseli ahlukahlukene.Ngaso leso sikhathi, i-Micro LED iphinde izuze izinzuzoIsibonisi se-LED, enokulungiswa okuphezulu, ukukhanya okuphezulu, impilo ende, i-gamut yombala ebanzi, izici ezizikhanyisayo, ukusetshenziswa kwamandla okuphansi, nokuzinza okungcono kwemvelo, ifanele izinhlelo zokusebenza zesibonisi esihlakaniphile sesikhathi esizayo, Njengezimoto, izibuko ze-AR, amadivayisi agqokekayo, njll.
Uma kuqhathaniswa nenqubo yokukhiqiza ye-LED yendabuko, izinyathelo zokukhula kwe-chip ye-Lei, ukukhiqizwa kwe-Micro LED chip, kanye nenqubo yokukhiqiza amafilimu amancane angasetshenziselwaP1.56 isibonisi se-LED esiguquguqukayoukukhiqiza kuphela ngokulungisa okokusebenza, kodwa kuba nzima kakhulu ukudlulisa, ukubona nokulungisa amanani amakhulu.Phakathi kwazo, ukudluliswa kwenqwaba, ukuhlolwa nokulungiswa, kanye nokusebenza kahle okukhanyayo kwe-Micro LED ebomvu yizingqinamba kubuchwepheshe bamanje, futhi ziyisihluthulelo sokuthinta izindleko nesivuno.Uma lezi zinkinga sezihlukanisiwe nezindleko zincishisiwe, kunethuba lokukhiqiza ngobuningi.qhubekela phambili.
Esinye sezithiyo ku-"New Horizons": Ukudluliselwa Kwenqwaba
Njengoba ubukhulu be-epitaxial substrate bukhulu kunosayizi we-chip, i-Micro LED kufanele idluliselwe ngobuningi, i-chip iyahlutshiwe, ibekwe endaweni yokugcina isikhashana, beseI-Micro LEDidluliselwa ebhodini lesifunda lokugcina noma inguqulo ye-TFT.Ubuchwepheshe bokudluliswa kwenqwaba kulesi sigaba buhlanganisa ukuhlanganisa uketshezi, ukudluliswa kwe-laser, ubuchwepheshe bokukhetha nendawo (I-Stamp Pick&Place), njll.
Ubuchwepheshe bokukhetha nendawo busebenzisa ubuchwepheshe be-MEMS bobuchwepheshe bokukhetha nendawo, kodwa ubuchwepheshe bendabuko be-LED bokukhetha nendawo buyabiza kakhulu ngenxa yezinga labo lokukhetha nendawo elihamba kancane;ngokuphathelene nokudluliswa kwe-laser, ama-Micro LED adluliswa ngokushesha futhi ngobuningi besuka ku-substrate yokuqala nge-laser beam Micro LED ukuze aqondise i-substrate.U-Yang Fubao, umhlaziyi we-TrendForce, uveze ukuthi ubuchwepheshe be-pickup bendabuko bekunzima ukukhiqiza ngobuningi ngenxa yesivinini sabo esihamba kancane kanye nezindleko eziphezulu esikhathini esidlule.Ngakho-ke, kulo nyaka, ubuchwepheshe bushintshile kancane kancane busuka ekuthathweni kwendabuko kuya kubuchwepheshe be-laser obunembayo obuphezulu nobushesha.ukudlulisa ukusiza ukunciphisa izindleko.Ngokuqondene nobuchwepheshe bokuhlanganisa uketshezi, ukuxhumana kwe-capillary ye-solder encibilikisiwe kuyasetshenziswa, futhi uketshezi oluyi-fluid suspension lungasetshenziswa njengendlela yokuxhumana phakathi nokuhlanganisa ukuxhuma ngomshini nangogesi ama-electrode, futhi ngokushesha kuthwebule futhi kuqondise ama-Micro LEDs emajoyintini e-solder. .Ukuhlanganiswa kwesivinini esiphezulu kungenzeka.Muva nje, uHuawei ubesebenzisa ngenkuthalo ubuchwepheshe be-Micro LED.Ngokombono wolwazi lwelungelo lobunikazi, kungenzeka kakhulu kusetshenziswe ubuchwepheshe bokuhlanganisa uketshezi.
"New Horizons" Isithiyo No. 2: Ukutholwa Nokulungiswa
Nakuba ukudluliswa kwenqwaba bekulokhu kuwukhiye wokukhiqiza ngobuningi, ukubaluleka kokuhlolwa nokulungiswa okulandelayo kwama-Micro LED chips akubalulekanga kangako kunokudluliswa ngobuningi.Njengamanje, izindlela ezimbili ezisetshenziswa kakhulu embonini yi-photoluminescence (PL) ne-electroluminescence (EL).Isici se-PL siwukuthi singahlolwa ngaphandle kokuxhumana noma ukulimaza i-chip ye-LED, kodwa umphumela wokuhlola awumuhle njengalowo we-EL;ngokuphambene nalokho, i-EL ingathola ukukhubazeka okwengeziwe ngokuhlola i-chip ye-LED ngokuyifaka ugesi, kodwa ingase ibangele ukulimala kwe-chip ngenxa yokuxhumana.
Ngaphezu kwalokho, i-Micro LED chip incane kakhulu ukuthi ifaneleke imishini yokuhlola evamile.Kungakhathaliseki ukuthi ukuhlolwa kwe-EL noma kwe-PL kuyasetshenziswa, kungase kube nesimo sokungatholakali kahle kahle, okuyingxenye edinga ukunqotshwa.Ngokuqondene nengxenye yokulungisa, abakhiqizi be-Micro LED basebenzisa ubuchwepheshe bokukhanda imisebe ye-ultraviolet, ubuchwepheshe bokulungisa ukuncibilika kwe-laser, ubuchwepheshe bokukhanda obukhethiwe, ubuchwepheshe bokukhanda be-laser obukhethiwe kanye nezixazululo zokuklama isekethe yesipele.
Isithiyo sesithathu ku-"New Horizons": Ama-chips e-Red Micro LED
Ekugcineni, kunombala wesibonisi ngokwawo.Kuma-Micro LED, uma kuqhathaniswa noluhlaza okwesibhakabhaka nokuluhlaza, umbala obomvu wumbala onzima kakhulu ukuwubonisa, futhi izindleko ziphezulu uma kuqhathaniswa.Ama-semiconductors e-Nitride njengamanje asetshenziswa embonini ukukhiqiza ama-Micro LED aluhlaza naluhlaza.Ama-Red Micro LED kufanele axutshwe nezinhlelo eziningi zezinto ezibonakalayo noma akhiqizwe ngama-semiconductors e-phosphide.
Nokho, inkinga yokufana kombala ingase yenzeke phakathi nenqubo ye-epitaxial.Ukuhlanganiswa kwezinto ezihlukene ze-semiconductor kuzokwandisa ubunzima bokukhiqiza kanye nezindleko zokukhiqiza zama-Micro LED anombala ogcwele.Inqubo yokusika ama-chips ingase iholele ekusebenzeni kahle kokukhanya, ingasaphathwa eyesayizi enciphayo., ukusebenza kahle kwe-phosphide Micro LED chips kuzoncishiswa kakhulu.Ukwengeza, imishini exubile iyadingeka ohlelweni lwe-semiconductor, ngakho-ke iyinkimbinkimbi, idla isikhathi, iyabiza, futhi isivuno sinzima ukuthuthukisa.
Ngakho-ke, abanye abakhiqizi baye bathuthuka kusukela ezintweni ngokwazo.Isibonelo, i-Porotech, inkampani ye-Micro LED, ikhiphe isibonisi sokuqala emhlabeni esisekelwe ku-indium gallium nitride (InGaN) esisekelwe ukukhanya okubomvu kwe-Micro LED, okusho ukuthi zontathu izinhlobo zezibonisi zisebenzisa i-InGaN njengento yokubonisa, engakhawulelwe kunoma yikuphi. i-substrate.Ngaphezu kwalokho, i-JBD, umkhiqizi omkhulu we-Micro LED, izibophezele kubuchwepheshe be-Micro LED e-AlGaInP ebomvu esikhathini esidlule, futhi isanda kumemezela ukuthi isifinyelele ama-nits angu-500,000 okukhanya okuphezulu okuphezulu okubomvu kwe-Micro LED mass production.
Nakuba singenise unyaka wokuqala we-Micro LED, izinkinga eziningi zisadinga isikhathi ukuze zixazululwe kancane.Njengamanje, sesibonile ukuqala kokusebenza.Kukholakala ukuthi ngemuva kokuthi izingqinamba ezinjengokudluliselwa kwenqwaba, ukuhlolwa nokugcinwa, kanye nokusebenza kahle okukhanyayo kunqotshwe ngamunye ngamunye, iMicro LED kulindeleke ukuthi ifezeke.Ukuhweba, ngokuzayo, izinhlelo zokusebenza ezilethwa yi-Micro LED zingabonakala ezikrinini zezimoto, izikrini ezinkulu zokubonisa, imishini ye-AR/VR,isibonisi esinesinqumo esiphezuluimikhiqizo egqokekayo, njll.
