Micro LED ifatwa nkigisubizo "cyanyuma", kandi ibyifuzo byayo hamwe nagaciro gashobora gukora birashimishije cyane.Amahirwe mashya yo gusaba nko kwerekana ibicuruzwa, televiziyo yo mu rwego rwo hejuru, ibinyabiziga n'ibikoresho byambara bikomeza kugera ku majyambere akomeye, kandi inganda zijyanye no kuzamuka no mu majyepfo zirimo guhindura urusobe rw'ibinyabuzima.
IbirahuriMicro LED yerekanaKugira imikorere myiza nibikorwa bitandukanye, kandi byitezwe ko bizakoreshwa cyane mubucuruzi bwerekana, televiziyo yo mu rwego rwo hejuru, ibinyabiziga, hamwe n’ibikoresho byambara, bifite isoko rinini ku isoko.Kongera ibikoresho nibikoresho bizahinduka amahirwe yingenzi yo guteza imbere inganda, kandi biteganijwe ko bizavugurura urusobe rwibidukikije.Micro LED irashobora gutahura ubunini-bunini bwubusa bwerekana porogaramu, hamwe nikoranabuhanga nko gupakira modular hamwe nu kayira kegereye umuhanda bituma gutera kubusa bishoboka.Micro LED irashobora kandi kumenya ikoreshwa ryibikoresho byoguhuza.Mugaragaza ejo hazaza hateganijwe guhinduka urubuga, rushobora kumenya imirimo itandukanye nko gukorana binyuze muri sensor, no guca mubitekerezo "kwerekana".
Guhanga udushya kurwego rwibikoresho birashobora kuzana impinduramatwara kurwego rwimikorere.Hamwe no kwerekana 3D, imikoranire ya 3D, hamwe nikoranabuhanga rigenda rigaragara nka 5G hamwe namakuru makuru, icyerekezo cyiterambere cyerekana holographiche mugihe kizaza ntagushidikanya.Micro LED ishingiye ku kirahure irashobora gutwikira imirima ikoreshwa mubicuruzwa binini, bito n'ibiciriritse.Biteganijwe ko ingano y’isoko iziyongera vuba guhera mu 2024, kandi biteganijwe ko izubaka urwego rushya rw’ibidukikije n’inganda.
Nyuma yimyaka myinshi yubushakashatsi niterambere, Micro LED yerekanwe nini yageze kumugaragaro mubikorwa byumusaruro rusange muri uyumwaka, kandi ibaye imbaraga zikomeye mugutezimbere ibice bifitanye isano, ibikoresho nibikorwa byinganda.Kwiyongera kwabakora byinshi hamwe niterambere ryikomeza ryiterambere rya miniaturisation ryateyeInganda za Micro LEDkugirango dukomeze kugera ku iterambere rishya mu ikoranabuhanga, kandi igipimo cy’isoko nacyo cyakomeje kwaguka.
Usibye ibipimo binini byerekana, Micro LED ifite ibintu byiza cyane bishobora gukoreshwa hamwe nindege zoroshye kandi zinjira.Irashobora kwigaragaza mumodoka no kwerekana ibyerekanwa, gushiraho uburyo bushya bwo gusaba butandukanye nubuhanga bugezweho bwo kwerekana.Kwinjira kwabakora byinshi hamwe niterambere ryiterambere rya miniaturizasi bizaba urufunguzo rwo gukomeza kugabanya ibiciro bya chip.
Ibihe bizaza bigomba gushobora kubohora amaboko, no kwibanda kumikorere myinshi kuri ecran kugirango ugere kubikorwa.Ibi bisaba ko ibyerekanwa bigomba kuba bifite itandukaniro rinini, PPI ndende, umucyo mwinshi, ndetse nukuri kwagutse.Kugeza ubu, Micro LED irashobora guhaza ibikenewe byiterambere byinganda zizaza, ariko inzira yinganda iracyakenewe kwihuta.Muri rusange, inganda za Micro LED zigomba kubanza kumenya umusaruro mwinshi wa chip hamwe no gukomeza kunoza imikorere.Icya kabiri, kwimura rusange bigomba guhuzwa no gusana kugirango umusaruro wibicuruzwa byinshi.Icya gatatu, mugihe cyo gutwara micro-current, umusaruro wa Micro LED ugomba kurushaho kunozwa.Hanyuma, ibidukikije byinganda biracyubakwa, kandi ibiciro byibyuma bigomba gukomeza kugabanuka.
Inganda zigomba gusuzuma uburyo bwo kuzamura umusaruro wa Micro LED, ikubiyemo gusana.Hano hari miliyoni icumi za LED muri TV.Niba bimuriwe muri substrate, nubwo igipimo cyumusaruro gishobora kugera kuri 99,99%, haracyari ahantu henshi hagomba gusanwa amaherezo, kandi bizatwara igihe kirekire.Hariho kandi ikibazo cyumucyo utaringaniye kwerekanwa.Mubyongeyeho, ukurikije umuvuduko mwinshi wumusaruro, igipimo cyumusaruro nigiciro, Micro LED iracyafite inyungu ugereranije nubu kristu ikuze cyane.Nubwo inganda zakoze imirimo myinshi mu kwimura imbaga, Micro LED iracyafite inzira ndende kugira ngo igere ku musaruro rusange.Hariho uburyo bubiri bwingenzi bwo kwimura imbaga, imwe ni Pick & Ahantu, naho ubundi ni laser mass transfert.
Nyuma yo kwerekana ibintu bisukuye, Micro LED ni umunywanyi ukomeye wibisekuru bishya byerekana tekinoroji yerekana, kandi chip ya Micro LED ntagushidikanya.Byumvikane ko ubunini bwa Micro LED ari kimwe gusa kwijana ryumwimerere wambere LED chip, igera kuri microni mirongo.
Kuva kuri LED kugeza Mini LED, nta tandukaniro rinini mubuhanga bwa chip hamwe na chip muri rusange, ariko ingano ya chip irahinduka.Impinduka zingenzi mugutezimbere Micro LED nuko igice cya chip kidashobora kurangizwa no kunanura no kwandika substrate ya safiro, ariko chip ya GaN igomba gukurwa mubutaka bwa safiro.Ikoranabuhanga risanzweho ni tekinoroji yo kuzamura laser gusa, ubwayo ninzira yangiza, idakuze cyane mubushinwa.Nibibazo byambere chip ihura nabyo.
Ikibazo cya kabiri nubucucike bwa disikuru ya Micro LED chip, ifite ingaruka nini cyane kumurongo wa chip ya Micro LED.Ku ikubitiro, ubucucike bwa dislocation muri epitaxy ya GaN LED bwari hejuru ya 1010. Nubwo ubwinshi bwa dislocation bwari bwinshi, imikorere ya luminous nayo yari hejuru.Nyuma ya gallium nitride LED ikorerwa mu Buyapani, nyuma yimyaka irenga 30 yiterambere, gutezimbere inzira bigeze hejuru, kandi ubucucike bwa dislokasiyo bugeze kuri 5 × 108.Ariko, kubera ubucucike bukabije bwa tekinoroji ya LED isanzwe, iterambere rya Micro LED rishobora kubuza cyane iterambere ryibicuruzwa byakurikiyeho.Kubwibyo, gukomeza tekinoroji ya LED iriho no guteza imbere Micro LED ikeneye gukemura ibibazo bibiri.Imwe ni ukongera kugabanya ubucucike bwibikoresho bya nitride ya gallium, naho ubundi ni ugushaka tekinoroji nziza yo kuzamura kuruta tekinoroji ya laser.
