Ukusatshalaliswa kobubanzi bomugqa wobuchwepheshe bokuphrinta be-inkjet obuhlukahlukene
Njengamanje, ubuchwepheshe obubili bokubonisa obujwayelekile, i-liquid crystal display (LCD) kanye ne-organic light-emitting diode (OLED), kusetshenziswe kuzibonisi eziseduze neso (NED) kanye nezibonisi ezifakwe amakhanda (HMDs).Kodwa-ke, ukuthuthukiswa kobuchwepheshe obusha bokuboniswa kusheshisiwe ngenxa yobubi obufana nokusebenza kahle kokuguqulwa okuphansi, ukugcwala kombala, nokuguga ngokushesha nempilo emfushane.
Ngokusebenza okuhle kakhulu kwe-optical nempilo ende,I-Micro LEDkubhekwa njengobuchwepheshe bokugcina bokubonisa besizukulwane esilandelayo.Ubuncane bosayizi wephikseli bufinyelela amashumi ama-microns, futhi ukuminyana kwamaphikseli aphezulu kwenza kube nokwenzeka ukuthi usetshenziswe ku-AR/VR.
Ngokuthuthuka okusheshayo kobuhlakani bokwenziwa, ukuqashelwa kwesithombe kanye nobuchwepheshe bokuxhumana be-5G, ubuqiniso obungathandwa kwabathelisi esikubona (AR) kanye nobuchwepheshe beqiniso elibonakalayo (VR) buthuthuka ngesivinini esishaqisayo.Esimweni sobhubhane olusha lomqhele, ukuxhumana ngezingcingo kanye nokusebenzisana kwabathengi abakude kuyakhula, futhi imakethe isiphinde yabhekisa ukunaka kwayo ku-AR/VR, nokutshalwa kwezimali kwezinhlelo zobuchwepheshe kunyukile.
Ngokusho kwe-IDC, kusukela ngo-2020 kuya ku-2024, usayizi wemakethe wezimboni zomhlaba wonke ze-AR ne-VR uzokhula usuka kuma-yuan ayizigidi eziyizinkulungwane ezingama-28 kanye nama-yuan ayizigidi eziyizinkulungwane ezingama-62 uye kumayuan ayizigidi eziyizinkulungwane ezingama-240, ngokulandelana.Esinye sezizathu eziyinhloko zokuqhuma kwemakethe ukuphumelela kobuchwepheshe obusha bokubonisa obusebenza kahle kakhulu.Njengento eyisisekelo ye-AR/VR, amadivayisi wokubonisa kufanele abe nayoukuminyana kwephikseli ephezulu kakhulukanye nesivinini sokuvuselela ngokushesha ngaphezu kwesisindo esincane nosayizi omncane.
Leli phepha lethula kuqala inqubekelaphambili yocwaningo lobuchwepheshe be-AR/VR, bese lixoxa ngenqubekelaphambili yocwaningo lwe-MicroIsibonisi se-LEDubuchwepheshe kanye nokuvumelana nezimo ku-AR/VR, kanye nezinzuzo zokulungisa isendlalelo sokuguqulwa kombala we-Micro LED ngobuchwepheshe bokuphrinta be-inkjet.Indlela yokudlulisa amandla engeyona imisebe kanye nomthelela wokuqina kosendlalelo sokuguqulwa kombala ekusebenzeni kahle kokuguqulwa kombala;ukuphakama kwe-SIJ ekulungisweni uma kuqhathaniswa nobunye ubuchwepheshe bokuphrinta kwethulwa.
Izincwadi kanye nelogo ye-school crest ephrintwe ubuchwepheshe be-SIJ
Ngaphezu kokuminyana kwamaphikseli aphezulu, umbala ogcwele uphinde ube yisici esibalulekile sokubona i-Micro LED ku-AR/VR.Phakathi kwabo, uhlelo lokuguqula umbala luyindlela ephumelelayo yokufeza umbala ogcwele.Amachashazi e-Quantum afakwa kuma-chips e-LED aluhlaza okwesibhakabhaka noma e-ultraviolet Micro ngobuchwepheshe bokuphrinta be-inkjet.I-luminescence enemibala emithathu iyafinyelelwa, kuyilapho igwema ukudluliswa komthamo omkhulu.
Eminyakeni yamuva nje, ubuchwepheshe obufana nokuphrinta kwe-inkjet ye-piezoelectric/thermal, ukuphrinta kwe-inkjet ye-aerosol, ukuphrinta kwe-inkjet ye-electrohydrodynamic, nokuphrinta kwe-inkjet okuyi-super inkjet kuye kwasetshenziswa ukuze kufakwe izendlalelo zokuguqulwa kombala, okubonisa amandla amakhulu okubona ama-Micro LED anombala ogcwele.Muva nje, ithimba likaProf. Zhang Rong wase-Xiamen University, ngokubambisana noProf. Guo Haozhong wase-Taiwan Chiao Tung University, lishicilele iphepha elinesihloko esithi "Principle of Inkjet Printing Technology and Its Application in AR/VR Microdisplays" ku-Opto-Electronic Advances. Ikhishwe ngomhla ka-5, 2022 "Isihloko sokubuyekeza.
Ingxenye yesibili yethula izimiso zokunyathelisa zobuchwepheshe obuhlukahlukene bokunyathelisa inkjet, kanye nezindaba ezimbili ezibalulekile: ukwenziwa kahle kwemingcele ye-rheological kayinki kanye nesixazululo somphumela wendandatho yekhofi.
Imingcele ye-rheological kayinki efanelekile kubuchwepheshe bokunyathelisa ngamunye kanye nomthelela wemingcele ye-rheological emphumeleni wokunyathelisa yethulwa.Izixazululo ezimbili zomphumela wendandatho yekhofi nezindlela ezithile zokuthuthukisa ziyabuyekezwa.Okokugcina, ezinye izinkinga ezingase zibe khona ezihlobene nezendlalelo zokuguqulwa kombala ziyagqanyiswa, okuhlanganisa i-optical crosstalk, ukumuncwa kokukhanya okuluhlaza okwesibhakabhaka, kanye nemiphumela yokuzibamba.
I-Micro LED ivula indlela yokuthengiswa kwe-AR/VR, futhi ukukhiqizwa kwe-Micro LED enombala ogcwele ene-pixel density ingenye yezingqinamba.Uhlelo lokuguqula umbala luyindlela ephumelelayo yokubona umbala ogcwele we-Micro LED, futhi ukuthuthukiswa kobuchwepheshe bokuphrinta be-inkjet kunikeza ukwesekwa kwezobuchwepheshe ekulungiselelenihigh-resolutionizingqimba zokuguqulwa kombala.
