Itekhnoloji yokubonisa isizukulwana esitsha elindelwe kakhulu, iMicro LED, isetyenziswa ukusuka kubukhulu ukuya kubukhulu obuncinci, kwaye ukusuka ngaphakathi ukuya ngaphandle.Le mikhomba-ndlela mibini yophuhliso isaqhubela phambili.Ukuza kuthi ga ngoku, amaziko ophando ahlukeneyo asenethemba malunga nokukhula kwexabiso lemarike ye-Micro LED.Kungcono ukubaisikrini esikhokelayo esiguqukayo.Nangona kunjalo, umba weendleko obambekayo kwindawo ephambili yorhwebo lwe-Micro LED usekwinqanaba lothethathethwano kunye nokusebenza phakathi kwamaqela anyukayo nasezantsi.Ngamafutshane, okwangoku akukho sisombululo sikhawulezayo nesisebenzayo kwii-Micro LEDs eziye zavakala ngokubanzi kwishishini.
Ukubona ukuba i-OLED iphucula iimpawu zohlengahlengiso lwemathiriyeli ngesantya esikhawulezayo, ingena kubathengi abaninzi be-elektroniki kunye neemarike zeemoto.Emva kokuba i-TFT LCD ene-MiniLED backlight isongelwa, ukuba ixesha lokuvelisa ubuninzi be-Micro LED ngexabiso elifanelekileyo libambezelekile, kunokubakho izinto eziguquguqukayo.Ngophuhliso lwetsheyini yoshishino lweMicro LED eTaiwan, iChichuang Technology inguvulindlela wezisombululo zobugcisa.
I-AUO kunye nenkampani edibeneyo yeFucai kulindeleke ukuba ibe nethuba lokukhokela ekulandeleni umthamo wokuvelisa ubuninzi.I-Micro LED ikhwaza iminyaka emininzi, kwaye ekugqibeleni yangena ngokusemthethweni kwimveliso yobuninzi kulo nyaka.Kulindeleke ukuba kubekho ukuhla okukhulu kwamaxabiso kunye neendleko kulo nyaka, kwaye kuya kuqhubeka ukuhla kwiminyaka embalwa ezayo.Oku kuza nangona kukho ukwehla kwemfuno yomthengi we-elektroniki kunye nenkcitho yeshishini phakathi kokunyuka kwamaxabiso ehlabathi kunye nokunyuswa kwenzala kwiibhanki ezingoovimba.
Eyokuqala iya kuba yi-miniaturization ye-Micro LED chips, ezinokuncitshiswa ngakumbi kwixesha elizayo.Oku kuthetha ukuba i-epitaxy efanayo inokufumana iitshiphusi ze-Micro LED ezingaphezulu, kwaye iindleko zeetshiphusi ze-Micro LED ziya kuhla.Ngaphaya koko, bayanda abavelisi beetshiphu
ukutyala imali kwiMicroIkhonkco loshishino lwe-LED, ekwanegalelo ekuphuculweni kwesivuno kunye nokunciphisa ixabiso kunye neendleko. Okwangoku, kuqikelelwa ukuba iitshiphusi ze-Micro LED zinethuba lokuhla ngesantya se-30% -40% ngonyaka, nto leyo enceda ukukhawulezisa inkqubo yorhwebo.
Ukongeza, ukusuka ekuphuculweni kwezixhobo zoomatshini kunye nenkqubo, ukuya kwi-back-end ye-wire bonding kunye nokudibanisa inkqubo, kukho indawo yokuphucula ukusebenza kakuhle kwe-Micro LED kunye nokunciphisa iindleko.Ii-Micro LEDs okwangoku zijolise kwiinkqubo ezininzi ekujoliswe kuzo.Kubandakanya izixhobo ezinxitywayo (ingakumbi iimveliso ezitsha ezifana neglasi ye-Metaverse AR), ii-TV ezinobungakanani obukhulu okanye iziboniso eziphezulu, iziboniso zemoto, njl. Ngokukodwa, ii-Micro LEDs zinokufakwa kwii-substrates eziguquguqukayo, ezinokudala iimilo ezininzi ezintsha kunye neemeko zokusetyenziswa.Phakathi kwazo, izixhobo ezinxitywayo kulindeleke ukuba zibe neemveliso ezitsha ngakumbi zisebenzisa iziboniso zeMicro LED ngo-2023.P1.5 Udonga lwevidiyo ye-LED.Kuya kubakho iibrendi ezininzi ezisungula iimveliso ezinxulumeneyo.Ukuqaliswa kwemiboniso yeemoto kuya kuthatha ixesha elide, kodwa i-HUD i-head-up displays inethuba lokuba yinkqubo ehamba phambili ye-Micro LED kwizicelo zemoto.
Kuyafaneleka ukukhankanya ukuba iteknoloji ye-Micro LED epitaxy.Ngefiziksi yamandla aphezulu, iifilimu ezikumgangatho ophezulu ze-GaN ezibhityileyo zinokukhuliswa kwiqondo lobushushu eliphantsi, ziyiyeke ngokupheleleyo inkqubo yokuhanjiswa kobuninzi.Iindleko sisinye kwishumi kuphela semiboniso ye-micro-LED ekhoyo.Inamandla okwenza imveliso ngobuninzi, kwaye ubuchwephesha obunxulumeneyo bufumene amalungelo awodwa abenzi eTaiwan nase-United States.
Ukudluliselwa ngobuninzi lelona nyathelo libalulekileyo kwiziboniso zeMicro LED zanamhlanje kwaye sele kuphuhliso malunga neshumi leminyaka.Kodwa iqela likholelwa ukuba ukudluliselwa okukhulu licala elingalunganga.Ikakhulu ngenxa yenkqubo yangoku ye-LED ye-whisker flip-chip kunye neenkqubo ezibuthathaka.Ukukhanya okuluhlaza okwesibhakabhaka yi-gallium nitride, kwaye ukukhanya okubomvu yi-gallium arsenide.I-voltage yokuqhuba yezinto ezimbini iyahluka, kwaye isiphaluka sokuqhuba siya kubangela ubunzima.Ngokukodwa malunga neendleko, ingxaki yokulungiswa kwe-pixel efileyo akukho lula ukuyoyisa, ngoko ke kunzima ukuvelisa ngobuninzi.
Ngokusebenzisa i-high-energy physics, umda wangaphambili wobushushu obuphezulu obungaphezulu kwe-1,000 degrees wophukile.Iifilimu ezikumgangatho ophezulu zegallium nitride zinokukhuliswa kumaqondo aphantsi, kwaye iqondo lobushushu linokulawulwa malunga nama-500 ukuya kuma-700 degrees.Ilungeleumboniso okhokelela elubala.Ubukhulu bephaneli bufumaneka ukusuka kwi-intshi ezi-2 ukuya kwi-intshi ezili-12.Inokunyuswa kunye nezixhobo zenkqubo kwaye idibaniswe nohlalutyo olukhulu lwedatha ukufumana eyona ndlela ilungileyo ye-epitaxial.Icwecwe layo le-epitaxial eliziphuhlisileyo, elidityaniswe netekhnoloji ye-nanomaterial, inokufikelela kumbala ogcweleyo we-micro-LED ukubonisa umphumo.Iindleko zephaneli enye isinye kwishumi kuphela kule ikhoyo, kwaye inamandla amakhulu okuvelisa ubuninzi.
