Ukadaulo woyembekezeredwa kwambiri wa m'badwo watsopano, Micro LED, ukugwiritsidwa ntchito kuyambira kukula mpaka kakang'ono, komanso kuchokera m'nyumba mpaka kunja.Njira ziwiri zazikuluzikuluzikuluzikuluzi zikupitabe patsogolo.Pakadali pano, mabungwe osiyanasiyana ofufuza akadali ndi chiyembekezo chokhudza kukula kwa msika wa Micro LED.Ndi bwino kuteroflexible LED screen.Komabe, nkhani yamtengo wapatali yomwe yatsala pang'ono kugulitsa malonda a Micro LED idakali pagawo la zokambirana ndikuyenda pakati pa maphwando akumtunda ndi pansi.Mwachidule, palibe yankho lachangu komanso lothandiza la ma Micro LED omwe afalikira kwambiri pamsika.
Kuwona kuti OLED ikusintha mawonekedwe azinthu zosinthika mwachangu kwambiri, ikulowa m'misika yogulitsa zamagetsi ndi magalimoto.Pambuyo pa TFT LCD yokhala ndi MiniLED backlight yakhala ikuwopsezedwa, ngati nthawi yopangira ma Micro LED pamtengo wokwanira ikuchedwa, pangakhale zosintha zambiri.Ndi chitukuko cha Micro LED makampani unyolo ku Taiwan, Chichuang Technology ndi mpainiya njira zothetsera luso.
AUO ndi kampani yake yogwirizana ndi Fucai akuyembekezeka kukhala ndi mwayi wotsogolera pakutsatizana kwakukulu kopanga mphamvu.Micro LED yakhala ikufuula kwa zaka zambiri, ndipo pamapeto pake idalowa mukupanga kwakukulu chaka chino.Zikuyembekezeka kuti padzakhala kuchepa kwakukulu kwa mitengo ndi ndalama chaka chino, ndipo zidzapitirizabe kuchepa m'zaka zingapo zikubwerazi.Izi zikubwera ngakhale kuchepa kwa kufunikira kwa magetsi ogula komanso kuwononga ndalama zamabizinesi mokhazikika pakukwera kwamitengo yapadziko lonse lapansi komanso kukwera kwa chiwongola dzanja ndi mabanki apakati.
Yoyamba idzakhala miniaturization ya Micro LED chips, zomwe zitha kuchepetsedwa mtsogolo.Izi zikutanthauza kuti epitaxy yomweyo imatha kupeza tchipisi ta Micro LED, ndipo mtengo wa tchipisi ta Micro LED udzatsika.Kuphatikiza apo, opanga ma chip akuchulukirachulukira
kuyika ndalama mu MicroUnyolo wamakampani a LEDPakali pano, akuti tchipisi ta Micro LED tili ndi mwayi wotsika pamlingo wa 30% -40% pachaka, zomwe zimathandizira kufulumizitsa ndondomeko yamalonda.
Kuphatikiza apo, kuyambira pakuwongolera zida zamakina ndi njira, mpaka kulumikiza mawaya akumbuyo ndikuphatikiza makina, palinso mwayi wowongolera magwiridwe antchito a Micro LED ndikuchepetsa mtengo.Ma Micro LED amayang'ana ntchito zingapo zomwe mukufuna.Kuphatikizapo zipangizo zovala (makamaka zatsopano monga galasi la Metaverse AR), ma TV akuluakulu kapena mawonedwe apamwamba, zowonetsera magalimoto, ndi zina zotero.Pakati pawo, zida zotha kuvala zikuyembekezeka kukhala ndi zinthu zatsopano zogwiritsa ntchito zowonetsera za Micro LED mu 2023.P1.5 LED kanema khoma.Padzakhalanso mitundu yambiri yoyambitsa zinthu zogwirizana.Kuyambitsidwa kwa zowonetsera zamagalimoto kudzatenga nthawi yayitali, koma ma HUD owonetsa mutu ali ndi mwayi wokhala otsogola a Micro LED pamapulogalamu apagalimoto.
Ndikoyenera kunena kuti ukadaulo wa Micro LED epitaxy.Kupyolera mu fiziki yamphamvu kwambiri, mafilimu apamwamba kwambiri a GaN amatha kukulitsidwa kutentha pang'ono, kusiya kwathunthu njira yosinthira anthu ambiri.Mtengo wake ndi gawo limodzi mwa magawo khumi a zowonetsera za micro-LED zomwe zilipo.Ili ndi kuthekera kopanga zinthu zambiri, ndipo matekinoloje okhudzana nawo adapeza ma patent ku Taiwan ndi United States.
Kusamutsa anthu ambiri ndiye gawo lofunikira kwambiri pazowonetsera zamasiku ano za Micro LED ndipo zakhala zikukula kwazaka pafupifupi khumi.Koma timuyi ikukhulupirira kuti kusamutsa kwakukulu ndi njira yolakwika.Makamaka chifukwa chamakono a LED chip whisker flip-chip ndondomeko ndi njira zofowokera.Chowala chobiriwira chobiriwira ndi gallium nitride, ndipo kuwala kofiira ndi gallium arsenide.Mphamvu yamagetsi yazinthu ziwirizi ndi yosiyana, ndipo dera loyendetsa galimoto limayambitsa zovuta.Makamaka pankhani ya mtengo, vuto la kukonza pixel yakufa silosavuta kuthana nalo, chifukwa chake ndizovuta kupanga zambiri.
Kupyolera mu sayansi yamagetsi yamphamvu kwambiri, malire am'mbuyomu otentha opitilira madigiri 1,000 adasweka.Makanema apamwamba kwambiri a gallium nitride amatha kukulitsidwa potentha kwambiri, ndipo kutentha kumatha kuyendetsedwa mozungulira madigiri 500 mpaka 700.Zabwino kwachiwonetsero cha LED chowonekera.Makulidwe apakati amapezeka kuyambira mainchesi 2 mpaka 12 mainchesi.Ikhoza kuwonjezeredwa ndi zipangizo zamakono ndikuphatikizidwa ndi kusanthula kwakukulu kwa deta kuti mupeze njira yabwino kwambiri ya epitaxial.Chomera chake chodzipangira chokha cha epitaxial, chophatikizidwa ndi ukadaulo wa nanomaterial, chimatha kukwaniritsa mawonekedwe amtundu wa micro-LED.Mtengo wa gulu limodzi ndi gawo limodzi mwa magawo khumi a omwe alipo, ndipo ali ndi kuthekera kwakukulu kopanga zambiri.
