M'munda wa tchipisi tambiri ta RGB, mapiri akutsogolo, chip-chip ndi zoyima ndi "zipilala zitatu", zomwe zida za safiro kutsogolo ndi chip-chip ndizofala kwambiri, ndipo zowoneka bwino nthawi zambiri zimatanthawuza zoonda. -filimu tchipisi za LED zomwe zachotsedwa pagawo.Gawo laling'ono latsopano likhoza kukhazikitsidwa kapena gawo lapansi silingamangidwe kuti lipange chip choyimirira.
Zogwirizana ndi zowonetsera zokhala ndi ma pitch osiyanasiyana, ubwino ndi kuipa kwa kutsogolo, flip-chip ndi nyumba zoyima ndizosiyana, koma mosasamala kanthu kufananitsa mawonekedwe a kutsogolo kapena flip-chip, ubwino wa mawonekedwe oyimirira mwa ena. mbali ndi zoonekeratu.
P1.25-P0.6: Zabwino zinayi zimaonekera
Lattice yayerekeza momwe tchipisi tating'onoting'ono ta 5 × 5mil za Lattice ndi tchipisi ta JD tomwe timagwiritsa ntchito 5 × 6mil poyesera.Zotsatira zake zimatsimikizira kuti poyerekeza ndi tchipisi toyimirira kutsogolo, tchipisi toyimirira mulibe kuwala kwa mbali chifukwa cha kuwala kwa mbali imodzi.Pamakhala kusokoneza pang'ono pamene malo akucheperachepera.Mwa kuyankhula kwina, kamvekedwe kakang'ono, kuwala kumachepa.Chifukwa chake, tchipisi choyimirira chimakhala ndi zabwino zowoneka bwino pakuwala kowala komanso kumveka bwino pamagawo ang'onoang'ono.
Mwachindunji, chip ofukula chimakhala ndi mawonekedwe otulutsa kuwala, kuwala kofananako, kugawa kosavuta, ndi ntchito yabwino yochepetsera kutentha, kotero kuti chiwonetserochi chikuwonekera bwino;Komanso, ofukula ma elekitirodi kapangidwe, kugawa panopa ndi yunifolomu kwambiri, ndi IV pamapindikira n'zogwirizana.Ma electrode ali mbali imodzi, pali kutsekeka kwamakono, ndipo kufanana kwa malo ounikira kumakhala koipa.Pankhani yopanga zokolola, kapangidwe ofukula angapulumutse mawaya awiri poyerekeza ndi dongosolo wamba okhazikika, ndi mawaya m'dera chipangizo ndi okwanira, amene angathe mogwira kuonjezera mphamvu yopanga zida ndi kuchepetsa chilema mlingo wa chipangizo chifukwa. kulumikiza waya ndi dongosolo la ukulu.
In kuwonetsa mapulogalamu,chodabwitsa cha "mbozi" nthawi zonse chakhala vuto lalikulu kwa opanga, ndipo gwero la chodabwitsa ichi ndi kusamuka kwachitsulo.Kusuntha kwachitsulo kumagwirizana kwambiri ndi kutentha, chinyezi, kusiyana komwe kungathe kuchitika ndi ma electrode a chip, ndipo nthawi zambiri zimawonekera pachiwonetsero chokhala ndi phokoso laling'ono.Mapangidwe amtundu wa chip alinso ndi maubwino achilengedwe pakuthana ndi kusamuka kwachitsulo.
Choyamba, mtunda pakati pa mitengo yabwino ndi yoyipa ya chip of vertical structure ndi wamkulu kuposa 135 μm.Chifukwa cha mtunda waukulu pakati pa mizati yabwino ndi zoipa mu danga thupi, ngakhale zitsulo ion kusamuka kumachitika, nyali mkanda moyo wa ofukula Chip akhoza kupitirira nthawi 4 kuposa chip yopingasa, amene kwambiri bwino mankhwala kudalirika. ndi kukhazikika.Ndi bwino kwachiwonetsero chosinthika.Chachiwiri ndi chakuti pamwamba pa chip blue-green chip ndi mawonekedwe osunthika ndi electrode yachitsulo yopanda mphamvu ya Ti / Pt / Au, yomwe imakhala yovuta kuti kusamuka kwachitsulo kuchitike, ndipo ntchito yake yaikulu ndi yofanana ndi yofiira. - Chip chowoneka bwino.Chachitatu ndi chakuti chipboard chokhazikika chimagwiritsa ntchito guluu wasiliva, womwe uli ndi matenthedwe abwino, ndipo kutentha mkati mwa nyali kumakhala kotsika kwambiri kusiyana ndi kukhazikitsidwa kovomerezeka, komwe kungachepetse kwambiri kuthamanga kwa zitsulo zachitsulo.
Pakadali pano, mu pulogalamu ya P1.25-P0.9, ngakhale yankho wamba lakutsogolo limakhala pamsika waukulu chifukwa cha mtengo wake wotsika mtengo, mayankho a flip-chip ndi ofukula amatenga gawo lalikulu pamapulogalamu apamwamba kwambiri. ku machitidwe awo apamwamba.Pankhani ya mtengo, mtengo wa gulu la RGB chips mu njira yowongoka ndi 1/2 ya flip-chip solution, kotero kuti mtengo wamtengo wapatali wa mawonekedwe osunthika ndi apamwamba.
Mu ntchito za P0.6-P0.9mm, mayankho wamba okwera kutsogolo amakhala ochepa ndi malire a danga, zimakhala zovuta kutsimikizira zokolola, komanso kuthekera kwa kupanga kwakukulu ndikotsika, pomwe mayankho a flip-chip ndi ofukula amatha kukumana ndi zofunika.Ndizofunikira kudziwa kuti, pafakitole yolongedza, ndikofunikira kuwonjezera zida zambiri kuti zigwirizane ndi dongosolo la flip-chip, komanso chifukwa mapepala awiri a flip-chip ndi ochepa kwambiri, kuchuluka kwa zokolola za solder phala. kuwotcherera si mkulu, ndi kukhwima kwa ma CD ndondomeko ya ofukula Chip chiwembu High, ma CD alipo
Zida za fakitale zitha kugwiritsidwa ntchito mofanana, ndipo mtengo wa RGB wa tchipisi zowongoka ndi theka lokha la seti ya RGB ya ma flip-chips, ndipo mtengo wonse wanjira yoyimirira ndi wapamwamba kuposa wa flip-chip solution.
P0.6-P0.3: Madalitso a njira ziwiri zazikulu zamakono
Pamapulogalamu a P0.6-P0.3, Lattice makamaka imayang'ana pa Thin Film LED, ukadaulo wocheperako wa filimu wopanda gawo laling'ono, wophimba mawonekedwe owoneka ndi mawonekedwe a chip chip.Kanema Wopyapyala wa LED nthawi zambiri amatanthauza kachipangizo kakang'ono ka filimu ya LED yomwe yachotsedwa pagawo.Gawoli likatha kuchotsedwa, gawo lapansi latsopano limatha kumangidwa kapena kupangidwa koyima popanda kumangiriza gawo lapansi.Imatchedwa Vertical thin film, kapena VTF mwachidule.Nthawi yomweyo, imathanso kupangidwa kukhala flip-chip kapangidwe popanda kumangiriza gawo lapansi, lomwe limatchedwa thin film flip chip, kapena TFFC mwachidule.
Njira yaukadaulo 1: Chip VTF/TFFC + quantum dot red light (QD + buluu kuwala InGaN LED)
Pansi pa kukula kwa chip yaying'ono kwambiri, AlGaInP yofiira ya LED imakhala ndi zida zosasinthika gawolo likachotsedwa, ndipo ndilosavuta kusweka panthawi yakusamutsa, zomwe zimapangitsa kuti zikhale zovuta kupanga zochulukirapo.Choncho, njira imodzi ndiyo kugwiritsa ntchito kusindikiza, kupopera mbewu mankhwalawa, kusindikiza ndi matekinoloje ena kuyika madontho a quantum pamwamba pa GaN blue LED kuti mupeze ma LED ofiira.
Njira yaukadaulo 2: Ma InGaN LED amagwiritsidwa ntchito mumitundu yonse ya RGB
Chifukwa chosakwanira mawotchi mphamvu ya alipo quaternary wofiira kuwala pambuyo kuchotsa gawo lapansi, n'zovuta kuchita wotsatira ndondomeko kupanga.Yankho lina ndiloti mitundu itatu ya RGB yonse ndi ma InGaN LEDs, ndipo nthawi yomweyo amazindikira kugwirizana kwa epitaxy ndi kupanga chip.Malinga ndi malipoti, Jingneng wayamba kufufuza ndi kupanga gallium nitride red light pazitsulo za silicon, ndipo zina zomwe zapindula zachitika mu silicon-based InGaN red light LEDs, zomwe zimapangitsa kuti teknolojiyi ikhale yotheka.
Ndizofunikira kudziwa kuti, poyerekeza zabwino ndi zovuta za TFFC, FC, ndi Micro tchipisi potengera gawo lapansi, kupatukana kwa chip, kuwala kowala, komanso kusamutsa anthu ambiri, Lattice adafika pomaliza: kugwiritsa ntchito njira yaukadaulo ya Micro ndi Lattice's Kuphatikiza kwa Tchipisi tating'ono zimatha kuchepetsa kwambiri mtengo wa chip ndikuchepetsa zovuta zaukadaulo.Izi zikutanthawuzanso kuti 4K ndi 8K Mini Ultra-high-definition LED zowonetsera zazikulu zikuyembekezeka kulowa m'nyumba masauzande ambiri.
Pakalipano, 4K ndi 8K Mini ultra-high-definition zowonetsera zazikulu ndi zosaimitsa zoyendetsedwa ndi teknoloji ya 5G, ndi silicon substrate vertical Mini LED chips ali ndi mwayi wokhala njira yowunikira yotsika mtengo kwambiri.
