Itekhnoloji yokubonisa isizukulwana esilandelayo iMicro LED iye yaba yeyona nto kugxilwe kuyo kulo nyaka weTouch Taiwan Smart Display Exhibition.Ngokuvulwa konyaka wokuqala we-Micro LED kunyaka ophelileyo, abavelisi abakhulu babonise iimeko ezininzi zokulinganisa kunye nezicelo ezijonge phambili kulo nyaka, kwaye i-2022 ngokungathandabuzekiyo iya kuba ngunyaka obalulekileyo emva kokuqala.Ngokuqhubeleka okuqhubekayo kwetekhnoloji, abavelisi be-Micro LED baye bawela ngokuthe ngcembe iintaba ezimbini "zeendleko" kunye "nesivuno", kwaye bajonge "kwindawo entsha" emehlweni e-Micro LED.
Inkqubo yeMicro LED yahlulwe ikakhulu kukukhula kwetshiphu, ukwenziwa kweetshiphu, inkqubo yefilimu ebhityileyo, ukuhanjiswa kobuninzi, ukuhlolwa nokulungiswa.Ngenxa yokususwa kwephakheji ye-LED kunye ne-substrate, ukushiya ifilimu ye-epitaxial, i-Micro LED chip ilula, incinci kwaye imfutshane, ibonelela ngeendidi ze-pixel zokubonisa.Kwangaxeshanye, i-Micro LED ifumana inzuzo ye-LED, enesisombululo esiphezulu, ukukhanya okuphezulu, ubomi obude, i-gamut yombala obanzi, iimpawu ezikhanyayo, ukusetyenziswa kwamandla aphantsi, kunye nozinzo olungcono lokusingqongileyo, olulungele umboniso wexesha elizayo, njengeemoto, iiglasi ze-AR, izixhobo ezinokunxitywa, njl.
Xa kuthelekiswa nenkqubo yokuvelisa LED zemveli, amanyathelo Lei chip ukukhula, Micro LED chip yokuvelisa, kunye nenkqubo yokuvelisa ifilim obhityileyo ingasetyenziselwa iMicro LED yokuvelisa kuphela ngokuguqula izixhobo, kodwa kunzima ngakumbi ukudlulisa, ukubona nokulungisa ezinkulu. izixa.Phakathi kwabo, ukuhanjiswa kobuninzi, ukuhlolwa kunye nokulungiswa, kunye nokusebenza kakuhle okukhanyayo kwe-Micro LED ebomvu yi-bottlenecks kwi-teknoloji yangoku, kwaye nayo iyisitshixo sokuchaphazela iindleko kunye nesivuno.Emva kokuba ezi ngxaki zichithwa kwaye iindleko ziyancipha, kukho ithuba lokuvelisa ngobuninzi.hambela phambili.
Omnye wemiqobo kwi "New Horizons": Ukudluliselwa ngobuninzi
Ekubeni ubukhulu be-epitaxial substrate bukhulu kunobukhulu be-chip, i-Micro LED kufuneka idluliselwe ngobuninzi, i-chip ihlulwe, ibekwe kwi-substrate yokugcina yesikhashana, emva koko i-Micro LED idluliselwe kwibhodi yesekethe yokugqibela. okanye inguqulelo yeTFT.Itekhnoloji ephambili yokudlulisa ubunzima kweli nqanaba ibandakanya ukudibanisa ulwelo, ukuhanjiswa kwelaser, ukukhetha kunye nokubeka itekhnoloji (Isitampu Pick&Place), njl.
Itekhnoloji yokukhetha kunye nendawo isebenzisa itekhnoloji ye-MEMS yoluhlu lwetekhnoloji ye-chip kunye nendawo, kodwaLED zemveliitekhnoloji yokukhetha-indawo inexabiso eliphezulu ngenxa yesantya sayo sokucotha kunye nendawo;malunga nokudluliselwa kwelaser, ii-Micro LEDs zigqithiselwa ngokukhawuleza nangokukhulu ukusuka kwi-substrate yokuqala nge-laser beam Micro LED ukujolisa kwi-substrate.U-Yang Fubao, umhlalutyi we-TrendForce, wachaza ukuba iteknoloji ye-pickup yendabuko bekunzima ukuyivelisa ngenxa yesantya esicothayo kunye neendleko eziphezulu kwixesha elidlulileyo.Ke ngoko, kulo nyaka, itekhnoloji ithe chu kancinci kancinci ukusuka kwifoto yemveli ukuya kwitekhnoloji echanekileyo kunye ne-laser ekhawulezayo.ukudluliselwa ukunceda ukunciphisa iindleko.Ngokuphathelele itekhnoloji yokudibanisa ulwelo, ujongano lwe-capillary etyhidiweyo ye-solder iyasetyenziswa, kwaye ulwelo lokumiswa kwamanzi lunokusetyenziswa njengento ephakathi ngexesha lokudityaniswa komatshini kunye nombane ukudibanisa i-electrode, kwaye ngokukhawuleza ubambe kwaye ulungelelanise ii-Micro LEDs kumalungu e-solder. .Indibano yesantya esiphezulu inokwenzeka.Kutshanje, uHuawei ebesebenzisa ngokusebenzayo itekhnoloji ye-Micro LED.Ngokwembono yolwazi lwelungelo elilodwa lomenzi wechiza, kusenokwenzeka ukuba kusetyenziswe iteknoloji yokudibanisa ulwelo.
"Ii-Horizons eziNtsha" Umqobo weNombolo ye-2: Ukufunyanwa kunye nokulungiswa
Nangona ukuhanjiswa kobuninzi bekuyeyona nto iphambili kwimveliso yobuninzi, ukubaluleka kokuhlolwa okulandelayo kunye nokulungiswa kwee-chips ze-Micro LED akubalulekanga ngaphantsi kokudluliselwa kobuninzi.Okwangoku, iindlela ezimbini eziqhelekileyo ezisetyenziswayo kwishishini yi-photoluminescence (PL) kunye ne-electroluminescence (EL).Uphawu lwe-PL lunokuthi luvavanywe ngaphandle kokuqhagamshelana okanye ukonakalisa i-chip ye-LED, kodwa umphumo wokuvavanya awukho njengoko u-EL;ngokuchaseneyo, i-EL inokufumana iziphene ngakumbi ngokuvavanya i-chip ye-LED ngokuyifakela umbane, kodwa inokubangela umonakalo we-chip ngenxa yoqhagamshelwano.
Ngaphaya koko, i-Micro LED chip incinci kakhulu ukuba ilungele izixhobo zovavanyo lwesintu.Kungakhathaliseki ukuba uvavanyo lwe-EL okanye lwe-PL lusetyenzisiweyo, kunokubakho imeko yokufumanisa ukusebenza kakuhle, okuyingxenye efuna ukunqotshwa.Ngokubhekiselele kwinxalenye yokulungisa, abavelisi be-Micro LED basebenzisa iteknoloji yokulungisa i-ultraviolet irradiation, iteknoloji yokulungisa i-laser melting, iteknoloji yokukhanda ekhethiweyo, iteknoloji yokulungisa i-laser kunye nezisombululo zokuyila isekethe.
Umqobo wesithathu kwi "New Horizons": Red Micro LED Chips
Ekugqibeleni, kukho umbala womboniso ngokwawo.Kwii-Micro LEDs, xa kuthelekiswa noluhlaza okwesibhakabhaka noluhlaza, obomvu ngowona mbala unzima ukuwubonisa, kwaye ixabiso liphezulu.I-Nitride semiconductors ngoku isetyenziswa kwishishini ukuvelisa ii-LED ezincinci eziluhlaza kunye nohlaza.Kungcono ukubaUmzi-mveliso wesikrini we-LED.Ii-LED ezincinci eziBomvu kufuneka zixutywe kunye neenkqubo ezininzi zezinto okanye ziveliswe nge-phosphide semiconductors.
Nangona kunjalo, ingxaki yombala ofanayo ingenzeka ngexesha lenkqubo ye-epitaxial.Ukudibanisa kwezixhobo ezahlukeneyo ze-semiconductor kuya kwandisa ubunzima bokuvelisa kunye neendleko zokuvelisa ze-Micro LEDs ezinombala ogcweleyo.Inkqubo yokusika iitshiphusi inokukhokelela ekusebenzeni kakubi kokukhanya, singasathethi ke ngobungakanani bokuncipha., ukusebenza kakuhle kwe-phosphide Micro LED chips kuya kuncitshiswa kakhulu.Ukongezelela, izixhobo ezixubileyo zifunekayo kwinkqubo ye-semiconductor, ngoko iyinkimbinkimbi, ichitha ixesha, iyabiza, kwaye isivuno sinzima ukuphucula.
Ngoko ke, abanye abavelisi baye baphucula kwizinto eziphathekayo ngokwazo.Ngokomzekelo, i-Porotech, inkampani ye-Micro LED, ikhuphe i-indium gallium nitride (InGaN) yokuqala ye-indium gallium nitride (InGaN)-esekelwe ukukhanya okubomvu kwe-Micro LED, okuthetha ukuba zontathu iindidi zokubonisa zisebenzisa i-InGaN njengemathiriyeli yokubonisa, engaphelelanga kuyo nayiphi na into. isubstrate.Ukongeza, i-JBD, umenzi omkhulu weMicro LED, uzibophelele kwitekhnoloji ye-AlGaInP ebomvu esekwe kwi-Micro LED kwixesha elidlulileyo, kwaye isandula ukubhengeza ukuba ifikelele kwi-500,000 ye-nits ye-ultra-high ebomvu yemveliso ye-Micro LED.
Nangona siye sangena kunyaka wokuqala weI-Micro LED, iingxaki ezininzi zisafuna ixesha lokuba ziconjululwe kancinane.Okwangoku, sikubonile ukuqala kokusetyenziswa.Kukholelwa ukuba emva kokuba iibhotile ezinje ngokugqithiselwa ngobuninzi, ukuhlolwa kunye nokugcinwa, kunye nokusebenza kakuhle okukhanyayo koyiswe enye enye, iMicro LED kulindeleke ukuba ifezekiswe.Ukurhweba, kwixesha elizayo, izicelo ezilethwa yi-Micro LED zingabonwa kwizikrini zemoto, izikrini ezinkulu zokubonisa, izixhobo ze-AR / VR, iimveliso ezinxitywayo eziphezulu, njl njl.
