I-MicroLED luhlobo lwe-diode ekhupha ukukhanya (i-LED), ngokuqhelekileyo ingaphantsi kwe-100μm ngobukhulu.Iisayizi eziqhelekileyo zingaphantsi kwe-50 μm, kwaye ezinye zincinci njenge-3-15 μm.Ngokomlinganiselo, iiMicroLED zimalunga ne-1/100 ubukhulu be-LED eqhelekileyo kunye ne-1/10 ububanzi beenwele zomntu.Kumboniso weMicroLED, ipikseli nganye ijongiwe kwaye iqhutywa ukuba ikhuphe ukukhanya ngaphandle kwesidingo sesibane esingasemva.Zenziwe ngezinto eziphathekayo, ezibonelela ubomi obude benkonzo.
I-PPI ye-MicroLED yi-5,000 kwaye ukukhanya yi-105nit.I-PPI ye-OLED yi-3500, kwaye ukukhanya yi-≤2 x 103nit.Njenge-OLED, izibonelelo ze-MicroLED kukukhanya okuphezulu, ukusetyenziswa kwamandla aphantsi, isisombululo esiphezulu kunye nokugcwala kombala.Olona ncedo lukhulu lwe-MicroLED luvela kweyona nto inkulu, inqanaba le-micron pitch.Ipixel nganye inokujongana nolawulo kunye nenqaku elinye lokuqhuba ukukhupha ukukhanya.Xa kuthelekiswa nezinye ii-LED, iMicroLED okwangoku ikwinqanaba eliphezulu malunga nokusebenza kakuhle okukhanyayo kunye noxinzelelo lwamandla akhanyayo, kwaye kusekho indawo yokuphucula.Ilungeleumboniso we-LED oguquguqukayo.Isiphumo sangoku sethiyori kukuba, ukuthelekisa i-MicroLED kunye ne-OLED, ukufezekisa ukukhanya okufanayo komboniso, kuphela malunga ne-10% yendawo yokugquma yale mva iyafuneka.Xa kuthelekiswa ne-OLED, ekwayi-self-luminous display, ukukhanya kumaxesha angama-30 aphezulu, kwaye isisombululo sinokufikelela kwi-1500PPI, elingana ne-5 amaxesha e-300PPI esetyenziswa yi-Apple Watch.
Ekubeni i-MicroLED isebenzisa izinto ezingabonakaliyo kwaye inesakhiwo esilula, ayinakho ukusetyenziswa kokukhanya.Ubomi bayo benkonzo bude kakhulu.Oku akunakuthelekiswa ne-OLED.Njengezinto eziphilayo, i-OLED ineziphene zayo zendalo-ubomi kunye nokuzinza, okunzima ukuthelekisa ne-QLED kunye ne-MicroLED yezinto ezingabonakaliyo.Uyakwazi ukuziqhelanisa nobukhulu obahlukeneyo.I-MicroLEDs inokuthi ifakwe kwii-substrates ezahlukeneyo ezifana neglasi, iplastiki, kunye nentsimbi, eyenza i-flexible, i-bandable displays.
Kukho indawo eninzi yokunciphisa iindleko.Okwangoku, iteknoloji ye-micro-projection idinga ukusetyenziswa komthombo wokukhanya wangaphandle, okwenza kube nzima ukunciphisa ubungakanani bemodyuli, kwaye ixabiso liphezulu.Ngokwahlukileyo, i-MicroLED microdisplay ezikhanyayo ayifuni umthombo wokukhanya wangaphandle, kwaye inkqubo ye-optical ilula.Ke ngoko, ineenzuzo kwi-miniaturization yomthamo wemodyuli kunye nokunciphisa iindleko.
Ngexesha elifutshane, imakethi ye-Micro-LED igxile kwimiboniso ye-ultra-encinci.Ngexesha eliphakathi kunye nexesha elide, imimandla yesicelo se-Micro-LED ibanzi kakhulu.Kuzo zonke izixhobo ezinxitywayo, izikrini ezinkulu zokubonisa zangaphakathi, izibonisi ezixhonywe entloko (i-HUDs), izibane zasemva, unxibelelwano lwe-wireless optical Li-Fi, i-AR/VR, iiprojektha kunye nezinye iindawo.
Umgaqo wokubonisa we-MicroLED kukubhitya, unciphise kwaye ulungelelanise uyilo lwesakhiwo se-LED.Ubungakanani bayo bumalunga ne-1 ~ 10μm kuphela.Emva koko, i-MicroLEDs idluliselwa kwi-substrates yesiphaluka kwiibhetshi, ezinokuthi zibe lukhuni okanye ziguquguquke ezicacileyo okanye i-opaque substrates.Umboniso we-LED ocacileyonayo ilungile.Emva koko, umaleko okhuselayo kunye ne-electrode ephezulu igqitywe yinkqubo yokubekwa komzimba, kwaye ke i-substrate ephezulu inokupakishwa ukugqiba umboniso we-MicroLED ngesakhiwo esilula.
Ukuze wenze umboniso, umphezulu wetshiphu kufuneka wenziwe ulungelelwaniso olufana nesiboniso se-LED, kwaye ipikseli yechaphaza ngalinye kufuneka ikwazi ukujongana kwaye ilawuleke kwaye iqhutywe ngabanye ukuze kukhanye.Ukuba iqhutywa yi-metal oxide semiconductor yesekethe encedisayo, iyinkqubo esebenzayo yokujongana nesakhiwo sokuqhuba, kwaye iteknoloji yokupakisha ingagqithiswa phakathi kwe-MicroLED array chip kunye ne-CMOS.
Emva kokuba i-paste igqityiwe, i-MicroLED inokuphucula ukukhanya kunye nokwahlukileyo ngokudibanisa uluhlu lwe-microlens.Uluhlu lweMicroLED luqhagamshelwe kwi-electrode elungileyo kunye nengalunganga ye-MicroLED nganye ngokusebenzisa i-electrode yegridi emile ngokuthe nkqo, kwaye i-electrodes inikwe amandla ngokulandelelana, kwaye iMicroLEDs ilayitiwe ngokuskena ukubonisa imifanekiso.
Njengekhonkco elivelayo kwikhonkco loshishino, i-Micro LED inenkqubo enzima ukuba amanye amashishini e-electronics awafane asebenzise-ukudluliselwa kobuninzi.Ukudluliselwa ngobuninzi kuthathwa njengento ephambili echaphazela izinga lesivuno kunye nokukhululwa kwamandla, kwaye ikwayindawo apho abavelisi abakhulu bagxila ekujonganeni neengxaki ezinzima.Okwangoku, kukho izikhokelo ezahlukeneyo kwindlela yobugcisa, oko kukuthi, ukudluliselwa kwelaser, iteknoloji yokuzihlanganisa kunye neteknoloji yokudlulisa.
Loluphi uhlobo lwetekhnoloji "lokudluliselwa ngobuninzi"?Ukuyibeka ngokulula, kwi-substrate yesekethe ye-TFT ubungakanani bozipho lomnwe, ngokweenkcukacha eziyimfuneko ze-optics kunye nombane, amakhulu amathathu ukuya kwamakhulu amahlanu okanye nangaphezulu, ii-micro-chips ze-LED ezibomvu, eziluhlaza kunye nebhlowu zidityaniswe ngokulinganayo.
Ireyithi yokungaphumeleli kwenkqubo evumelekileyo yi-1 kwi-100,000.Iimveliso kuphela ezifezekisa inkqubo enjalo zinokuthi zisetyenziswe ngokwenene kwiimveliso ezifana ne-Apple Watch 3. I-teknoloji ye-Surface Mount ngoku iphumelele ukuveliswa kweteknoloji yokudlulisa ubuninzi kwi-MINI LED, kodwa idinga ukuqinisekiswa okusebenzayo kwimveliso ye-MicroLED.
NangonaIziboniso zeMicroLEDzibiza kakhulu xa kuthelekiswa neepaneli ze-LCD kunye ne-OLED eziqhelekileyo, inzuzo yazo ekukhanyeni kunye nokusebenza kakuhle kwamandla kuzenza zibe yinto ekhangayo kwi-ultra-encinci kunye nezicelo ezinkulu kakhulu.Ngokuhamba kwexesha, inkqubo yokuvelisa i-MicroLED iya kuvumela ababoneleli ukuba banciphise iindleko zokuvelisa.Nje ukuba inkqubo ifikelele ekuvuthweni, ukuthengiswa kweMicroLED kuya kuqala ukunyuka.Ukubonisa lo mkhwa, ngo-2026, iindleko zokwenziwa kwe-1.5-intshi ye-microLED yokubonisa ii-smartwatches kulindeleke ukuba yehle ukuya kwishumi leendleko zangoku.Ngexesha elifanayo, ixabiso lokuvelisa i-75-intshi ye-intshi ye-TV iya kuhla ukuya kwi-fifth yexabiso layo langoku ngexesha elifanayo.
Kwiminyaka emibini edlulileyo, i-Mini Led industry iya kutshintsha ngokukhawuleza iteknoloji yokubonisa yendabuko.Kwi-2021, imboni yokubonisa i-elektroniki efana nokubonisa isithuthi, umboniso wezixhobo zekhaya, umboniso wenkomfa, umboniso wokhuseleko kunye namanye amashishini omboniso we-elektroniki uya kuqalisa ukuhlaselwa ngokubanzi kwaye aqhubeke kuze kube yilapho iteknoloji yokuvelisa i-Micro LED izinzile.
