Mu rwego rwibisobanuro bihanitse bya RGB byerekana chip, imbere-kwishyiriraho, flip-chip hamwe nuburyo buhagaritse ni "inkingi eshatu", murizo zisanzwe za safiro imbere-imbere na flip-chip ibyubatswe ni byinshi, kandi ibyerekezo bihagaritse ubusanzwe bivuga ubunini -filime LED chip yakuwe muri substrate.Substrate nshya irashobora gukosorwa cyangwa substrate ntishobora guhuzwa kugirango ikore chip ihagaritse.
Bihuye no kwerekana ecran hamwe nibibuga bitandukanye, ibyiza nibibi byimbere-yimbere, flip-chip nuburyo buhagaritse biratandukanye, ariko ntakibazo cyo kugereranya imiterere-yimbere cyangwa imiterere ya flip-chip, ibyiza byuburyo bwa vertical muri bamwe ibintu biragaragara.
P1.25-P0.6: Ibyiza bine biragaragara
Lattice yagereranije imikorere ya Lattice ihagaritse 5 × 5mil chip hamwe na JD ya 5 × 6mil chip binyuze mubushakashatsi.Ibisubizo byerekana ko ugereranije na chip-imbere yimbere, ibyuma bihagaritse bidafite urumuri kuruhande kubera urumuri rumwe.Hano harumucyo muke nkuko intera iba nto.Muyandi magambo, ntoya ikibuga, gutakaza umucyo muke.Kubwibyo, uduce duhagaritse dufite ibyiza bigaragara mubwinshi bwumucyo no kwerekana neza mubibuga bito.
By'umwihariko, vertical chip ifite urumuri rwinshi rusohora imiterere, urumuri rumwe rusohoka, gukwirakwiza urumuri rworoshye, hamwe nubushuhe bwiza bwo gukwirakwiza, bityo kwerekana ingaruka birasobanutse;mubyongeyeho, vertical electrode imiterere, ikwirakwizwa ryubu rirasa, kandi umurongo wa IV urahoraho.Electrode iri kuruhande rumwe, hariho kuzitira, kandi uburinganire bwumucyo ni bubi.Ku bijyanye n’umusaruro utanga umusaruro, imiterere ihagaritse irashobora kuzigama insinga ebyiri ugereranije nuburyo busanzwe busanzwe, kandi aho insinga zikoreshwa mubikoresho zirahagije, zishobora kongera neza ubushobozi bwibikorwa byibikoresho kandi bikagabanya umuvuduko wibikoresho byigikoresho gikwiye guhuza insinga ukurikije gahunda yubunini.
In Kugaragaza Porogaramu,ibintu bya "caterpillar" byahoze ari ikibazo gikomeye kubabikora, kandi intandaro yibi bintu ni kwimuka kwicyuma.Kwimuka kwicyuma bifitanye isano rya hafi nubushyuhe, ubushuhe, itandukaniro rishobora kuba hamwe nibikoresho bya electrode ya chip, kandi birashoboka cyane ko bigaragara mubyerekanwe hamwe n'ikibanza gito.Imiterere ya vertical chip yuzuye nayo ifite ibyiza bisanzwe mugukemura ibyuma byimuka.
Ubwa mbere, intera iri hagati yibyiza nibibi bya pole ya vertical structure chip irenze 135 mm.Bitewe nintera nini hagati yinkingi nziza nibibi mumwanya wumubiri, nubwo icyuma cya ion cyimuka kibaye, itara ryamatara yubuzima bwa chip vertical irashobora kuba inshuro zirenga 4 kurenza iya chip ya horizontal, itezimbere cyane kwizerwa ryibicuruzwa n'umutekano.Nibyiza kurikwerekana byoroshye.Iya kabiri ni uko ubuso bwa chip yubururu-icyatsi gifite imiterere ihagaritse ni all-inert yicyuma electrode Ti / Pt / Au, bigoye kwimuka kwicyuma kubaho, kandi imikorere yacyo nyamukuru ni nkiyumutuku -umucyo uhagaze.Iya gatatu ni uko imiterere ya vertical chip ikoresha glue ya silver, ifite ubushyuhe bwiza bwumuriro, kandi ubushyuhe buri mumatara buri munsi cyane ugereranije nubushakashatsi busanzwe, bushobora kugabanya cyane umuvuduko wimuka wa ioni.
Kuri iki cyiciro, muri porogaramu ya P1.25-P0.9, nubwo igisubizo gisanzwe cyashyizwe imbere gifata isoko nyamukuru kubera inyungu zacyo nkeya, flip-chip hamwe nibisubizo bihagaritse bigira uruhare runini mubisabwa murwego rwo hejuru bitewe Kuri imikorere yabo yo hejuru.Kubijyanye nigiciro, igiciro cyitsinda rya chipi ya RGB mugisubizo gihagaritse ni 1/2 cyumuti wa flip-chip, bityo imikorere yikiguzi cyimiterere ihanamye.
Muri porogaramu ya P0.6-P0.9mm, ibisubizo bisanzwe-byashizwe imbere bigarukira kumipaka igaragara, biragoye kwemeza umusaruro, kandi birashoboka ko umusaruro mwinshi ari muke, mugihe flip-chip hamwe na vertical chip ibisubizo bishobora guhura na ibisabwa.Birakwiye ko tumenya ko, ku ruganda rupakira, birakenewe kongeramo ibikoresho byinshi kugirango habeho gahunda yimiterere ya flip-chip, kandi kubera ko amakariso abiri ya flip-chip ari nto cyane, igipimo cyumusaruro wa paste ugurisha gusudira ntabwo biri hejuru, kandi gukura muburyo bwo gupakira gahunda ya vertical chip plan Hejuru, ibipfunyika bihari
ibikoresho byuruganda birashobora gukoreshwa mubisanzwe, kandi ikiguzi cya seti ya RGB kuri chip vertical ni kimwe cya kabiri cyicyiciro cya RGB kuri flip-chip, kandi muri rusange imikorere yikiguzi cyibisubizo nayo irenze iyo i flip-chip igisubizo.
P0.6-P0.3: Umugisha winzira ebyiri zingenzi
Kubisabwa P0.6-P0.3, Lattice yibanda cyane kuri Thin Film LED, tekinoroji ya firime yoroheje idafite substrate, ikubiyemo imiterere ihagaritse hamwe na chip chip.Filime ntoya LED muri rusange yerekeza kuri firime yoroheje LED chip yakuwe muri substrate.Nyuma yo kwamburwa substrate, substrate nshya irashobora guhuzwa cyangwa imiterere ihagaritse irashobora gukorwa idahuza substrate.Yitwa Vertical thin film, cyangwa VTF mugihe gito.Muri icyo gihe, irashobora kandi gukorwa muburyo bwa flip-chip idahuza substrate, ibyo bita thin film flip chip, cyangwa TFFC mugihe gito.
Inzira ya tekiniki 1: VTF / TFFC chip + Quant dot itara ritukura (QD + itara ry'ubururu InGaN LED)
Munsi ya chip ntoya cyane, gakondo ya AlGaInP itukura LED ifite imiterere yubukanishi nyuma yo gukuramo substrate, kandi biroroshye cyane kumeneka mugihe cyo kwimura, bikagorana gukora umusaruro mwinshi nyuma.Kubwibyo, igisubizo kimwe ni ugukoresha icapiro, gutera, gucapa nubundi buryo bwikoranabuhanga kugirango ushire utudomo twa kwant hejuru yubururu bwa GaN ubururu kugirango ubone LED zitukura.
Inzira ya Tekinike 2: InGaN LED zikoreshwa mumabara yose ya RGB
Bitewe nimbaraga zidahagije zumucyo zitukura zihari nyuma yo gukuraho substrate, biragoye gukora umusaruro ukurikira.Ikindi gisubizo nuko amabara atatu ya RGB yose ari InGaN LEDs, kandi icyarimwe akamenya guhuza epitaxy na chip inganda.Nk’uko amakuru abitangaza, Jingneng yatangiye ubushakashatsi n’iterambere ry’umucyo utukura wa gallium nitride kuri substrate ya silicon, kandi hari ibyagezweho mu matara atukura ya InGaN ashingiye kuri silicon, bituma bishoboka kuri iryo koranabuhanga.
Twabibutsa ko, mugereranije ibyiza nibibi bya TFFC, FC, na Micro chip mubijyanye na substrate, gutandukanya chip, gukora neza, no kwimura abantu benshi, Lattice yaje gufata umwanzuro: ukoresheje inzira ya tekinike ya Micro hamwe na Lattice Ihuriro rya Mini chip irashobora kugabanya cyane ibiciro bya chip mugihe bigabanya ingorane za tekiniki.Ibi bivuze kandi ko 4K na 8K Mini ultra-high-definition LED ibicuruzwa binini byerekana ko byinjira mu ngo ibihumbi.
Kugeza ubu, 4K na 8K Mini ultra-high-definition yerekana ecran nini ntishobora guhagarara bitewe na tekinoroji ya 5G, kandi silicon substrate vertical Mini LED chip ifite amahirwe yo kuba igisubizo cyiza cyane cyumucyo utanga isoko.
