Ndi chitukuko chosalekeza cha MicroChiwonetsero cha LED, zapita patsogolo zambiri pazaumisiri.Posachedwapa, pakhala pali chitukuko chatsopano mu zowonetsera za Micro LED, ndipo pakhala pali zambiri zatsopano zamakono padziko lapansi.
Yonsei University imapanga ukadaulo wowoneka bwino wamitundu itatu ya Micro LED
Akuti gulu la Pulofesa Jong-hyun Ahn wa dipatimenti ya Electrical and Electronic Engineering ku Yonsei University adagwiritsa ntchito ma semiconductors a MoS2 ndi madontho a quantum kuti akwaniritse ukadaulo wowonetsera wamtundu wa Micro LED. ," ndipo ndi dziko loyamba kupanga umisiri wophatikizika wogwiritsa ntchito ma semiconductors okhala ndi mbali ziwiri ndi madontho a quantum, akuyembekezeka kugwiritsidwa ntchito popanga zowonetsera za m'badwo wotsatira wa high-performance augmented reality (AR) ndi virtual reality (VR).Ndi uthenga wabwino kwaMakampani a LED.
Kuti mupange chiwonetsero cha Micro LED, njira yovuta yosamutsira tchipisi tamitundu itatu ya Micro LED kupita ku bolodi yozungulira yakumbuyo imafunika.Ngakhale kuti njira yopangira iyi ndi yoyenera kupanga mawonedwe akuluakulu okhala ndi malingaliro otsika, sangathe kukwaniritsa zofuna za m'badwo wotsatira wa augmented reality (AR) ndi mawonedwe enieni (VR) omwe amafunikira kusamvana kwakukulu ndi ntchito yothamanga kwambiri.
Pofuna kuthana ndi luso lopanga ma Micro LED owonetsa, gulu lofufuza lidapanga cholumikizira chamitundu iwiri cha semiconductor molybdenum disulfide (MoS2) molunjika pa gallium nitride (GaN) wowotchera ma LED a buluu, ndikuphatikiza ma semiconductor kuti apange ma semiconductor amtundu uliwonse, anazindikira bwino dziko loyamba 500 PPI (chiwerengero cha Micro LED kuwala magwero inchi), mkulu-kusamvana Micro LED anasonyeza popanda njira kusamutsa.Kuphatikiza apo, gulu lofufuza lapanganso njira yopezera mitundu itatu yoyambirira posindikiza madontho ochulukirapo pamagetsi amtundu wa GaN Micro LEDs, zomwe zitha kupititsa patsogolo zokolola zowonetsera ndikuchepetsa mtengo wopanga.Kuphatikiza apo, ukadaulo wopangidwa ndi gulu lofufuza sungathe kufewetsa zovuta zopanga za MicroLED imawonetsa malonda, komanso kukwaniritsa kusamvana kwakukulu.
Yunivesite ya Kyung Hee imapanga mawonekedwe apamwamba kwambiri a zida za AR
Posachedwapa, gulu lofufuza motsogozedwa ndi Pulofesa Lee Seung-hyun wa dipatimenti ya Electronic Engineering ku Kyung Hee University adagwiritsa ntchito ma diode ophatikizika kwambiri (omwe amatchedwa ma Micro LED) kuti apange zida zowoneka bwino zokhala ndi fumbi lalikulu la pixel. particles ndi madontho a quantum ndi mtundu wabwino kwambiri.Zobwezeretsa.Mipikisano ya zinthu zowoneka bwino ikuyembekezeka kugwiritsidwa ntchito popanga zithunzi zenizeni zenizeni m'maso.Fusion ndiyovuta chifukwa cha kusiyana kwa magawo opangira ma circulation amagetsi ndi ma Micro LED.Nthawi zambiri, mabwalo amagetsi amapangidwa pazigawo za silicon, pomwe ma Micro LED amapangidwa pagawo la gallium nitride.Kuti athetse vutoli, gulu lofufuza la Pulofesa Li linapanga njira yomwe imatha kusamutsa magawo opyapyala a gallium nitride, pafupifupi gawo limodzi mwa magawo khumi a makulidwe a tsitsi la munthu, kupita ku gawo lapansi la silicon.
Kutengera ukadaulo uwu, gulu lofufuza lidapanga pixel yaying'ono kwambiri padziko lonse lapansi (5μm) ya LED pogwiritsa ntchito ukadaulo wa silicon wokhawokha komanso osawonetsa njira zonse."Njira yosinthira imakhudzidwa kwambiri ndi kufalikira kwa matenthedwe, kotero tidayang'ana kwambiri kupanga zigawo zowonda za aloyi pa kutentha kochepa," adatero wophunzira waukadaulo wamagetsi Shin Yoo-seop.Nthawi yomweyo, gulu lofufuza lidagwiritsa ntchito ukadaulo wa madontho a quantum kuti apititse patsogolo kuchuluka kwa utoto, ndikuwonjezera kuzindikira ku AR.Madontho a Quantum akopa chidwi kwambiri ngati zida za m'badwo wotsatira zotulutsa kuwala chifukwa cha kuyera kwawo kwamtundu wapamwamba komanso kutha kwa zithunzi poyerekeza ndi zida zanthawi zonse zotulutsa kuwala chifukwa zimatha kupangidwa popanga utali wosiyanasiyana wa mafunde a kuwala pagawo lililonse la tinthu popanda kusintha mtundu.zipangizo zamitundu yosiyanasiyana.Komabe, madontho a quantum amatha kutengeka ndi zosungunulira zosiyanasiyana zomwe zimagwiritsidwa ntchito pokonza semiconductor.
Kuti athetse vutoli, gulu lofufuza linapanga "njira yowuma yowuma kwambiri" yomwe imatha kusankha molingana ndi mphamvu yamphamvu ya padziko lapansi.Adachita bwino kugwiritsa ntchito ukadaulo wa quantum dot kuti akwaniritse mtundu wa RGB popanda zosungunulira.Ma pixel opangidwa owoneka bwino ndi ang'ono kwambiri ngakhale atawonedwa kudzera pa maikulosikopu, kuwapangitsa kukhala oyenera zida zazing'ono monga zovala.Kuphatikiza apo, ma pixel owoneka bwino amatha bwinoled projectzithunzi zenizeni zenizeni powonetsa mtundu wapamwamba wa gamut.
