Ukuqalisa
Eminyakeni yamuva nje, ubuchwepheshe be-Micro LED budonsele ukunakwa okukhulu emkhakheni wokubonisa futhi kubhekwe njengobuchwepheshe bokubonisa olandelayo wesizukulwane esilandelayo. I-Micro LED uhlobo olusha lwe-LED oluncane kune-LED yendabuko, ngobubanzi bezinkulungwane zama-micrometers ambalwa kuma-micrometer angamakhulu ambalwa. Lobu buchwepheshe bunezinzuzo zokukhanya okuphezulu, umehluko omkhulu, ukusetshenziswa kwamandla okuphansi, kanye nokuphila okude, okukwenza kulungele izinhlelo eziningi zezicelo. Leli phepha lihlose ukuhlinzeka ngesibukezo sobuchwepheshe be-LED micro ye-LED, kufaka phakathi incazelo yalo, umlando wokuthuthuka, izinqubo zokukhiqiza ezibalulekile, izinselelo zezobuchwepheshe, izinhlelo zokusebenza, nezinkampani ezihlobene namathemba esizayo.
Ukuchazwa kwe-LED encane
I-Micro LED uhlobo lwe-LED oluncane kakhulu kune-LED yendabuko, ngosayizi osukela kuma-micrometer ambalwa kuya kuma-micrometer angamakhulu ambalwa. Ubukhulu obuncane be-LED le-micro buvumela ukuqina okuphezulu kanye nokubuyiselwa okuphezulu, okungahlinzeka ngezithombe ezicacile nezinamandla. I-Micro LED ngumthombo wokukhanyisa wombuso oqinile osebenzisa ama-diode akhanyisiwe ukukhiqiza ukukhanya. Ngokungafani nokuboniswa kwe-LED yendabuko, ukuboniswa kwama-LED amancane kwenziwa ngama-LED amancane anamathele ngqo esibonelweni sokubonisa, aqede isidingo sokukhanya okukhazimulayo.
Umlando Wentuthuko
Ukuthuthukiswa kobuchwepheshe be-Micro LED bubuyela emuva kuma-1990s, lapho abacwaningi baqala ukucubungula umbono wokusebenzisa ama-micro aholwa njengobuchwepheshe bokubonisa. Kodwa-ke, ubuchwepheshe abusebenzi ngokuhweba ngaleso sikhathi ngenxa yokuntuleka kwezinqubo zokukhiqiza ezisebenza kahle nezingabizi. Eminyakeni yamuva nje, ngokuthuthuka okusheshayo kobuchwepheshe bama-semiconductor kanye nesidingo esandayo sokubonisa kokusebenza okuphezulu, ubuchwepheshe be-LED micro buthuthuke kakhulu. Namuhla, ubuchwepheshe be-LED Micro buye baba yisihloko esishisayo embonini yezimpawu, futhi izinkampani eziningi zitshale imali kakhulu ocwaningweni nasekuthuthukisweni kobuchwepheshe be-LED Micro.
Izinqubo zokukhiqiza ezibalulekile
Ukwenziwa kwemibukiso ye-Micro LED kuhilela izinqubo ezimbalwa ezibalulekile, kufaka phakathi ukwakheka kwe-wafer, ukudilizwa kokufa, ukudluliselwa, kanye nokuchazwa. Ukwakheka okuhlanzekile kubandakanya ukukhula kwezinto eziholwa yi-LED ku-wafer, kulandelwa ukwakheka kwamadivayisi aholwa ngamancane amancane. Ukuqunjelwa kokufa kubandakanya ukuhlukaniswa kwamadivayisi aholwa amancane avela ku-wafer. Inqubo yokudlulisa ifaka ukuhanjiswa kwamadivayisi aholwa amancane avela ku-wafer ku-substrate eboniswayo. Ekugcineni, ukubhema kufaka phakathi ukunikezwa kwamadivayisi aholwa yi-Micro aholwa ukuba awavikele ezicini zezemvelo futhi athuthukise ukuthembeka kwawo.
Izinselelo Zezobuchwepheshe
Naphezu kwamandla amakhulu wezobuchwepheshe be-LED ezincane, kunezingqinamba eziningi zobuchwepheshe ezidinga ukunqotshwa ngaphambi kokuba i-LED ye-Micro. Enye yezinselelo eziphambili ukuhanjiswa okusebenzayo kwamadivayisi aholwa amancane avela ku-wafer esibonelweni esiseduze. Le nqubo ibalulekile ekwakheni ukuboniswa kwekhwalithi ephezulu ye-LED, kepha kunzima futhi futhi kudinga ukunemba okuphezulu nokunemba. Enye inselelo ukubekezelela amadivaysi amancane aholwa yi-LED, okumele avikele amadivaysi ezicini zezemvelo futhi athuthukise ukuthembeka kwawo. Ezinye izinselelo zifaka ukuthuthuka kokukhanya kanye nokufana kombala, ukuncishiswa kokusetshenziswa kwamandla, kanye nokuthuthukiswa kwezinqubo zokukhiqiza ezingabizi kakhulu.
Izicelo ze-IRRRE LED
Ubuchwepheshe be-Micro LED bunobubanzi bezicelo ezingaba khona, kufaka phakathi i-elekthronikhi yabathengi, izimoto, ezokwelapha nokukhangisa. Emkhakheni we-elekthronikhi yabathengi, ukuboniswa kwama-LED amancane kungasetshenziswa kuma-Smartphones, ama-laptops, amathelevishini namadivayisi agqoke kahle ngokukhanya okuphezulu, umehluko omkhulu. Embonini yezimoto, ukuboniswa kwe-LED micro kungasetshenziswa ekubonisweni kwemoto, ukuhlinzeka abashayeli ngezithombe ezisezingeni eliphakeme neziphezulu. Emkhakheni wezokwelapha, ukuboniswa kwe-LED eyi-Micro kungasetshenziswa e-Endoscopy, kuhlinzeka odokotela ngezithombe ezicacile nezinemininingwane yezitho zangaphakathi zesiguli. Embonini yokukhangisa, ukuboniswa kwe-LED encane kungasetjenziselwa ukudala ama-polivery amakhulu, aphezulu wokuxazulula izilungiselelo zokukhangisa kwangaphandle, ukuhlinzeka ngolwazi olubukwayo olunomthelela omkhulu.
