I-Micro LED ithathwa njengesisombululo "sokugqibela", kwaye ithemba lesicelo sayo kunye nexabiso elinokuthi lilenze linomtsalane kakhulu.Amathuba amatsha ezicelo ezifana neziboniso zorhwebo, iiTV eziphezulu, izithuthi kunye nezixhobo ezinxitywayo ziqhubeka nokuphumeza uphuhliso olunamandla, kwaye amashishini anxulumeneyo anyukayo kunye nezantsi ahlaziya i-ecosystem yokubonisa.
Iglasi-esekelweIziboniso ze-Micro LEDzinomsebenzi ogqwesileyo kunye nemisebenzi eguquguqukayo, kwaye kulindeleke ukuba zisetyenziswe ngokubanzi kwimiboniso yentengiso, iiTV eziphezulu, izithuthi, kunye nezinto ezinxitywayo, ezinokubakho kwimarike enkulu.Ukongeza izixhobo ezitsha kunye nemathiriyeli iya kuba lithuba elibalulekileyo lophuhliso lwemizi-mveliso, kwaye kulindeleke ukuba imise ngokutsha inkqubo yendalo yoshishino.I-Micro LED inokuqonda ubungakanani obukhulu bezicelo zokudityaniswa kwasimahla, kwaye itekhnoloji efana nokupakishwa kweemodyuli kunye nocingo olusecaleni lwenza ukuba ukudibanisa kwasimahla kwenzeke.I-Micro LED inokuqonda usetyenziso lokudityaniswa kwesixhobo esisebenzayo.Isikrini sekamva kulindeleke ukuba sibe siqonga, esinokuqonda imisebenzi eyahlukeneyo efana nokusebenzisana ngokusebenzisa abenzi boluvo, kwaye kwaphule ingcamango "yokubonisa".
Ukwenziwa kwezinto ezintsha kumgangatho wesixhobo kunokuzisa uguqulo kumgangatho wokusebenza.Ngomboniso we-3D, ukusebenzisana kwe-3D, kunye nobuchwepheshe obuvelayo obufana ne-5G kunye nedatha enkulu, ulwalathiso lophuhliso lwe-holographic display kwixesha elizayo ngokungathandabuzekiyo lunomdla.I-Micro LED esekwe kwiglasi inokugubungela amasimi osetyenziso lweemveliso ezinkulu, eziphakathi kunye nezincinci.Ubungakanani bemakethi kulindeleke ukuba bukhule ngokukhawuleza ukusuka ngo-2024, kwaye kulindeleke ukuba kwakhiwe ikhonkco elitsha lemizi-mveliso yendalo.
Emva kweminyaka yophando kunye nophuhliso, i-Micro LED umboniso omkhulu ufikelele ngokusesikweni kwinqanaba lokuvelisa ngobuninzi kulo nyaka, kwaye uye waba ngumqhubi onamandla kuphuhliso lwamacandelo ahambelanayo, izixhobo kunye neenkqubo zokuvelisa.Ukongezwa kwabaninzi abavelisi kunye nentsingiselo yophuhliso oluqhubekayo lwe-miniaturization iye yabangela ukubaImboni encinci ye-LEDukuphumeza ngokuqhubekayo impumelelo entsha yobuchwepheshe, kwaye isikali semarike siqhubekile nokukhula.
Ukongeza kwimiboniso emikhulu, i-Micro LED ineempawu ezintle ezinokuthi zisetyenziswe kunye ne-backplanes eguquguqukayo kunye nokungena.Inokuvela kwi-automotive display kunye ne-wearable display, idala ithuba elitsha lesicelo esahlukileyo kwi-teknoloji yangoku yokubonisa.Ukungena kwabavelisi abaninzi kunye nendlela yokuphuhlisa i-miniaturization eqhubekayo iya kuba ngundoqo ekunciphiseni okuqhubekayo kweendleko ze-chip.
Imiboniso yexesha elizayo kufuneka ikwazi ukukhulula izandla, kwaye igxininise imisebenzi emininzi kwisikrini ukufezekisa intsebenziswano.Oku kufuna ukuba umboniso kufuneka unomahluko ophezulu, iPPI ephezulu, ukukhanya okuphezulu, kunye nenyani eyandisiweyo.Okwangoku, iMicro LED inokuhlangabezana neemfuno zophuhliso lweshishini lokubonisa elizayo, kodwa inkqubo yoshishino isafuna ukukhawuleziswa.Ngokubanzi, ukwenziwa kwemizi-mveliso yeMicro LED kufuneka kuqala iqonde imveliso yobuninzi beetshiphusi kunye nokuqhubela phambili kokusebenza.Okwesibini, ukuhanjiswa kobuninzi kufuneka kudityaniswe nokulungiswa ukufezekisa ukuveliswa kweemveliso ezininzi.Okwesithathu, phantsi kweemeko zokuqhuba i-micro-current, ukusebenza kakuhle kwe-Micro LED kufuneka kuphuculwe ngakumbi.Okokugqibela, i-ikholoji yemizi-mveliso isakhiwa, kwaye iindleko zehardware kufuneka ziqhubeke nokuhla.
Ishishini kufuneka liqwalasele indlela yokuphucula imveliso yeMicro LED, ebandakanya ukulungiswa.Kukho amashumi ezigidi zee-LED kumabonwakude.Ukuba zithunyelwa kwi-substrate, nokuba izinga lesivuno lingafikelela kwi-99.99%, kusekho iindawo ezininzi ezifuna ukulungiswa ekugqibeleni, kwaye kuya kuthatha ixesha elide.Kukwakho ingxaki yokukhanya okungalinganiyo kumboniso.Ukongeza, ngokumalunga nesantya semveliso yobuninzi, izinga lesivuno kunye neendleko, iMicro LED isenayo inzuzo xa ithelekiswa nekristale yolwelo eqolileyo ngoku.Nangona ishishini lenze umsebenzi omninzi ekugqithiseni abantu abaninzi, iMicro LED isenendlela ende ekufuneka ihambe ngaphambi kokuba ifezekise imveliso yobuninzi.Kukho iindlela ezimbini eziphambili zokudluliselwa kobuninzi, enye yi-Pick&Place, kwaye enye yi-laser mass transfer.
Emva komboniso wekristale yolwelo, i-Micro LED ikhuphisana nesizukulwana esitsha sobuchwephesha be-iteration, kunye ne-Micro LED chip ngokungathandabuzekiyo ikhonkco eliphambili.Kuyaqondwa ukuba ubungakanani be-Micro LED yipesenti enye kuphela ye-chip ye-LED yokuqala, efikelela kumyalelo wamashumi eemicrons.
Ukusuka kwi-LED ukuya kwi-Mini LED, akukho mahluko mkhulu kwi-teknoloji ye-chip kunye nenkqubo ye-chip, kodwa ubukhulu be-chip buyatshintsha.Utshintsho olubalulekileyo ekuphuhliseni i-Micro LED kukuba i-chip segmentation ayinakugqitywa ngokunciphisa kunye nokubhala i-sapphire substrate, kodwa i-chip ye-GaN kufuneka ikhutshwe kwi-sapphire substrate ngokuthe ngqo.Ubuchwephesha obukhoyo bubuchwephesha bokuphakamisa i-laser kuphela, yona ngokwayo iyinkqubo eyonakalisayo, engavuthwanga kakhulu e-China.Le yingxaki yokuqala ejongene nayo itshiphu.
Ingxaki yesibini kukuxinana dislocation lwe Micro LED chip, nto leyo enempembelelo enkulu kakhulu kwicala ukungaguquguquki chip Micro LED.Ekuqaleni, ukuxinana kwe-dislocation kwi-GaN LED epitaxy yayiphezulu njenge-1010. Nangona ukuxinana kwe-dislocation kwakuphezulu, ukukhanya okukhanyayo kwakuphezulu.Emva kokuba i-gallium nitride LED iveliswe eJapan, emva kweminyaka engaphezu kwe-30 yophuhliso, ukuphuculwa kwenkqubo kufikelele kwisilingi, kwaye ukuxinana kwe-dislocation kufikelele kwi-5 × 108.Nangona kunjalo, ngenxa yoxinaniso oluphezulu lwetekhnoloji ye-LED ekhoyo, uphuhliso lweMicro LED lunokuthintela kakhulu uphuhliso lweemveliso ezilandelayo.Ngoko ke, ukuqhubeka nobuchwepheshe be-chip ye-LED ekhoyo kunye nokuphuhlisa i-Micro LED idinga ukusombulula iingxaki ezimbini.Enye kukunciphisa ngakumbi ukuxinana kwe-dislocation ye-gallium nitride materials, kwaye enye kukufumana iteknoloji yokuphakamisa engcono kuneteknoloji yokuphakamisa i-laser.
