I-MicroLED iwuhlobo lwe-light emitting diode (LED), ngokuvamile engaphansi kuka-100μm ngosayizi.Osayizi abajwayelekile bangaphansi kuka-50 μm, kanti abanye bancane kakhulu njengo-3-15 μm.Ngokwesilinganiso, ama-MicroLED angaba ngu-1/100 ubukhulu be-LED evamile futhi cishe 1/10 ububanzi bezinwele zomuntu.Kusibonisi se-MicroLED, i-pixel ngayinye iqondiswa futhi iqhutshwa ukuze ikhiphe ukukhanya ngaphandle kwesidingo sokukhanya kwangemuva.Zenziwe ngezinto ezingaphili, ezinikeza impilo ende yenkonzo.
I-PPI ye-MicroLED ingu-5,000 futhi ukukhanya kuyi-105nit.I-PPI ye-OLED ingu-3500, futhi ukukhanya kungu-≤2 x 103nit.Njenge-OLED, izinzuzo ze-MicroLED ukukhanya okuphezulu, ukusetshenziswa kwamandla okuphansi, ukulungiswa kwe-ultra-high kanye nokugcwala kombala.Inzuzo enkulu ye-MicroLED ivela esicini sayo esikhulu kunazo zonke, iphimbo leleveli ye-micron.Iphikseli ngalinye lingabhekana nokulawula kanye nokushayela kwephoyinti elilodwa ukuze kukhishwe ukukhanya.Uma kuqhathaniswa namanye ama-LED, iMicroLED okwamanje isezingeni eliphezulu ngokusebenza kahle okukhanyayo kanye nokuminyana kwamandla akhanyayo, futhi sisekhona indawo yokuthuthukiswa.Ilungeleisibonisi se-LED esiguquguqukayo.Umphumela wamanje wasetiyetha ukuthi, ukuqhathanisa i-MicroLED ne-OLED, ukuze kuzuzwe ukukhanya okufanayo kwesibonisi, cishe u-10% wendawo yokumboza wakamuva odingekayo.Uma kuqhathaniswa ne-OLED, ephinde ibe isibonisi esizikhanyisayo, ukukhanya kuphakeme izikhathi ezingama-30, futhi ukulungiswa kungafinyelela ku-1500PPI, okulingana nezikhathi ezi-5 kune-300PPI esetshenziswa i-Apple Watch.
Njengoba i-MicroLED isebenzisa izinto ezingaphili futhi inesakhiwo esilula, cishe ayinakho ukusetshenziswa kokukhanya.Impilo yayo yesevisi yinde kakhulu.Lokhu akunakuqhathaniswa ne-OLED.Njengento ephilayo, i-OLED inamaphutha ayo emvelo-ubude bempilo nokuzinza, okunzima ukukuqhathanisa ne-QLED ne-MicroLED yezinto ezingaphili.Iyakwazi ukuzivumelanisa nosayizi abahlukahlukene.Ama-MicroLED angafakwa kuma-substrates ahlukene njengengilazi, ipulasitiki, nensimbi, okuvumela izibonisi eziguquguqukayo, ezigobekayo.
Maningi indawo yokunciphisa izindleko.Njengamanje, ubuchwepheshe be-micro-projection budinga ukusetshenziswa komthombo wokukhanya wangaphandle, okwenza kube nzima ukuqhubeka nokunciphisa ubukhulu bemodyuli, futhi izindleko nazo ziphezulu.Ngokuphambene, i-MicroLED microdisplay ezikhanyayo ayidingi umthombo wokukhanya wangaphandle, futhi isistimu ye-optical ilula.Ngakho-ke, inezinzuzo ku-miniaturization yevolumu yemojuli kanye nokunciphisa izindleko.
Esikhathini esifushane, imakethe ye-Micro-LED igxile ekubonisweni kwe-ultra-small.Esikhathini esimaphakathi nesikhathi eside, izinkambu zokusetshenziswa ze-Micro-LED zibanzi kakhulu.Kumadivayisi agqokekayo kuwo wonke, izikrini ezinkulu zokubonisa zasendlini, izibonisi ezifakwe ekhanda (ama-HUD), izibani zangemuva, ukuxhumana okungenantambo kwe-Li-Fi, i-AR/VR, amaphrojektha nezinye izinkambu.
Umgomo wokubonisa we-MicroLED uwukuba mncane, unciphise futhi uhlele umklamo wesakhiwo se-LED.Ubukhulu bayo buyi-1 ~ 10μm kuphela.Ngemva kwalokho, ama-MicroLED adluliselwa kuma-substrates esifunda ngamaqoqo, angaba ama-substrates aqinile noma aguquguqukayo abonisa ngale noma a-opaque.Isibonisi se-LED esobalafuthi kuhle.Khona-ke, ungqimba oluvikelayo kanye ne-electrode engenhla kuqedwa inqubo yokubeka ngokomzimba, bese i-substrate engenhla ingahlanganiswa ukuze igcwalise isibonisi se-MicroLED ngesakhiwo esilula.
Ukuze kwenziwe isibonisi, ingaphezulu le-chip kufanele lenziwe libe isakhiwo samalungu afanayo nesibonisi se-LED, futhi iphikseli yechashazi ngalinye kufanele likwazi ukubhekana nokubhekana nalo futhi lilawuleke futhi lishayelwe ngalinye ukuze kukhanye.Uma ishayelwa isekethe ye-metal oxide semiconductor ehambisanayo, iyisakhiwo sokukhuluma esisebenzayo, futhi ubuchwepheshe bokupakisha bungadluliswa phakathi kwe-MicroLED array chip ne-CMOS.
Ngemuva kokuthi ukunamathisela sekuqediwe, i-MicroLED ingathuthukisa ukugqama nokugqama ngokuhlanganisa ama-microlens array.Amalungu afanayo e-MicroLED axhunywe kuma-electrode aqondile noma angalungile e-MicroLED ngayinye ngokusebenzisa ama-electrode egridi amile abheke phezulu, futhi ama-electrode anikezwa amandla ngokulandelana, futhi ama-MicroLED akhanya ngokuskena ukuze abonise izithombe.
Njengesixhumanisi esisafufusa ochungechungeni lwemboni, i-Micro LED inenqubo enzima ezinye izimboni ze-elekthronikhi ezingavamile ukuyisebenzisa-ukudlulisa ngobuningi.Ukudluliswa kwenqwaba kuthathwa njengento ewumgogodla ethinta izinga lesivuno kanye nokukhululwa kwamandla, futhi kuyindawo lapho abakhiqizi abakhulu begxila ekubhekaneni nezinkinga ezinzima.Njengamanje, kunezikhombisi-ndlela ezihlukene emzileni wezobuchwepheshe, okungukuthi ukudluliswa kwe-laser, ubuchwepheshe bokuzihlanganisa kanye nobuchwepheshe bokudlulisa.
Hlobo luni lobuchwepheshe "lokudlulisa ngobuningi"?Ukukubeka kalula, ku-TFT circuit substrate ubukhulu bozipho lomunwe, ngokusho kwemininingwane edingekayo ye-optics kanye nogesi, amakhulu amathathu kuya kwayisihlanu noma ngaphezulu ama-micro-chips e-LED abomvu, aluhlaza okwesibhakabhaka ashiselwe ngokulinganayo.
Izinga lokuhluleka kwenqubo elivumelekile ngu-1 kokungu-100,000.Imikhiqizo efinyelela inqubo enjalo kuphela engasetshenziswa ngempela emikhiqizweni efana ne-Apple Watch 3. Ubuchwepheshe be-Surface mount manje sebuzuze ukukhiqizwa kobuchwepheshe bokudlulisa ngobuningi ku-MINI LED, kodwa budinga ukuqinisekiswa okungokoqobo ekukhiqizeni kwe-MicroLED.
NakubaIzibonisi ze-MicroLEDzibiza kakhulu uma kuqhathaniswa namaphaneli e-LCD avamile kanye ne-OLED, izinzuzo zawo ekukhanyeni nasekusebenziseni amandla kahle ziwenza abe enye indlela ekhangayo ezinhlelweni zokusebenza ezincane nezinkulu kakhulu.Ngokuhamba kwesikhathi, inqubo yokukhiqiza ye-MicroLED izovumela abahlinzeki ukuba banciphise izindleko zokukhiqiza.Uma inqubo isifinyelele ekuvuthweni, ukuthengiswa kweMicroLED kuzoqala ukukhuphuka.Ukukhombisa lo mkhuba, ngo-2026, izindleko zokukhiqiza zama-smartwatch angu-1.5-intshi we-smartwatches kulindeleke ukuthi zehle zibe ingxenye yeshumi yezindleko zamanje.Ngesikhathi esifanayo, izindleko zokukhiqiza zesibonisi se-TV esingama-intshi angu-75 zizokwehla zibe ingxenye yesihlanu yezindleko zayo zamanje ngesikhathi esifanayo.
Eminyakeni emibili edlule, imboni ye-Mini Led izothatha indawo ngokushesha ubuchwepheshe bokubonisa bendabuko.Ngo-2021, imboni yokubonisa i-elekthronikhi efana nesibonisi sezimoto, isibonisi sezinto zikagesi zasendlini, isibonisi senkomfa, isibonisi sezokuphepha nezinye izimboni zokubonisa i-elekthronikhi zizoqala ukuhlasela okuvamile futhi kuqhubeke kuze kube yilapho ubuchwepheshe bokukhiqiza ngobuningi be-Micro LED buzinzile.
