Micro LED imatengedwa kuti ndi yankho la "ultimate display", ndipo mwayi wogwiritsa ntchito komanso mtengo womwe ungapange ndiwokongola kwambiri.Mwayi watsopano wogwiritsa ntchito monga zowonetsera zamalonda, ma TV apamwamba kwambiri, magalimoto ndi zida zovalira zikupitilizabe kupititsa patsogolo chitukuko champhamvu, ndipo mafakitale okhudzana ndi kumtunda ndi kumunsi akukonzanso mawonekedwe achilengedwe.
Zopangidwa ndi galasiMawonekedwe a Micro LEDali ndi magwiridwe antchito abwino kwambiri komanso osunthika, ndipo akuyembekezeka kugwiritsidwa ntchito kwambiri pazowonetsa zamalonda, ma TV apamwamba, magalimoto, ndi zobvala, zokhala ndi msika waukulu.Kuwonjezera zida zatsopano ndi zida kudzakhala mwayi wofunikira pachitukuko cha mafakitale, ndipo akuyembekezeka kukonzanso chilengedwe chamakampani owonetsera.Ma LED ang'onoang'ono amatha kuzindikira zowonetsera zazikulu zazikulu zaulere, ndipo matekinoloje monga ma modular ma CD ndi waya wam'mbali amapangitsa kuti kulumikizana kwaulere kutheke.Micro LED imathanso kuzindikira kugwiritsa ntchito kuphatikizika kwa zida.Chophimba cham'tsogolo chikuyembekezeka kukhala nsanja, yomwe imatha kuzindikira ntchito zosiyanasiyana monga kuyanjana kudzera mu masensa, ndikuphwanya lingaliro la "kuwonetsa".
Zatsopano pamlingo wa chipangizo zimatha kubweretsa kusintha kwa magwiridwe antchito.Ndi chiwonetsero cha 3D, kuyanjana kwa 3D, ndi matekinoloje omwe akubwera monga 5G ndi data yayikulu, njira yachitukuko yowonetsera holographic mtsogolo mosakayikira imakhala yosangalatsa.Glass-based Micro LED imatha kuphimba magawo azinthu zazikulu, zapakati komanso zazing'ono.Kukula kwa msika kukuyembekezeka kukula mwachangu kuyambira 2024, ndipo akuyembekezeka kupanga njira zatsopano zamafakitale kumtunda ndi kumunsi kwazachilengedwe.
Pambuyo pazaka zafukufuku ndi chitukuko, chiwonetsero chachikulu cha Micro LED chafika pachimake pakupanga zinthu zambiri chaka chino, ndipo chakhala chiwongolero champhamvu pakupanga zinthu zofananira, zida ndi njira zopangira.Kuwonjezeredwa kwa opanga ambiri komanso mayendedwe opitilira patsogolo a miniaturization adalimbikitsaMakampani a Micro LEDkuti akwaniritse zopambana zatsopano zaukadaulo mosalekeza, komanso kukula kwa msika kukupitilizabe kukula.
Kuphatikiza pa zowonetsera zazikulu, Micro LED ili ndi mawonekedwe abwino kwambiri omwe angagwiritsidwe ntchito ndi ndege zosinthika komanso zolowera kumbuyo.Itha kuwonekera pamawonekedwe agalimoto ndi zowoneka bwino, ndikupanga mwayi watsopano wogwiritsa ntchito womwe ndi wosiyana ndiukadaulo wamakono wowonetsera.Kulowa kwa opanga ambiri ndi chitukuko cha miniaturization mosalekeza chidzakhala chinsinsi cha kuchepetsa kosalekeza kwa mtengo wa chip.
Zowonetsera zam'tsogolo ziyenera kumasula manja, ndikuyang'ana ntchito zingapo pazenera kuti mukwaniritse kulumikizana.Izi zimafuna kuti chiwonetserocho chikhale ndi kusiyana kwakukulu, PPI yapamwamba, kuwala kwambiri, komanso zenizeni zowonjezera.Pakadali pano, Micro LED imatha kukwaniritsa zosowa zamakampani owonetsera mtsogolo, koma njira yamakampani ikufunikabe kufulumizitsa.Nthawi zambiri, kutukuka kwa Micro LED kuyenera kuzindikira kaye kuchuluka kwa tchipisi ndi kukhathamiritsa kosalekeza kwa magwiridwe antchito.Chachiwiri, kusamutsa anthu ambiri kuyenera kuphatikizidwa ndi kukonza kuti akwaniritse kupanga zinthu zambiri.Chachitatu, pansi pa kayendetsedwe ka micro-current, kupanga kwa Micro LED kuyenera kukonzedwanso.Potsirizira pake, chilengedwe cha mafakitale chikumangidwabe, ndipo mtengo wa hardware uyenera kupitiriza kutsika.
Makampani akuyenera kuganizira momwe angapititsire kutulutsa kwa Micro LED, komwe kumaphatikizapo kukonza.Pali ma LED mamiliyoni ambiri pa TV.Ngati atasamutsidwa ku gawo lapansi, ngakhale zokolola zimatha kufika 99.99%, pali malo ambiri omwe akuyenera kukonzedwa pamapeto pake, ndipo zidzatenga nthawi yaitali.Palinso vuto la kuwala kosagwirizana pachiwonetsero.Kuphatikiza apo, pankhani ya liwiro lopanga misa, kuchuluka kwa zokolola komanso mtengo, Micro LED ilibe phindu lililonse poyerekeza ndi kristalo wamadzi okhwima kwambiri.Ngakhale makampaniwa achita ntchito zambiri pakusamutsa anthu ambiri, Micro LED ikadali ndi njira yayitali kuti ikwaniritse kupanga kwakukulu.Pali njira ziwiri zazikulu zosinthira anthu ambiri, imodzi ndi Pick&Place, ndipo ina ndi kusamutsa misa ya laser.
Pambuyo pakuwonetsa kristalo wamadzimadzi, Micro LED ndi mpikisano wamphamvu waukadaulo watsopano waukadaulo wowonetsa, ndipo Micro LED chip mosakayikira ndiye ulalo wofunikira.Zimamveka kuti kukula kwa Micro LED ndi gawo limodzi mwa magawo khumi a chipangizo choyambirira cha LED, chomwe chimafika pa dongosolo la ma microns.
Kuchokera ku LED kupita ku Mini LED, palibe kusiyana kwakukulu mu teknoloji ya chip ndi ndondomeko ya chip makamaka, koma kukula kwa chip kukusintha.Kusintha kofunikira pakukula kwa Micro LED ndikuti magawo a chip sangathe kumalizidwa ndi kupatulira ndikulemba gawo la safiro, koma chipangizo cha GaN chiyenera kuchotsedwa pamtengo wa safiro mwachindunji.Ukadaulo womwe ulipo ndiukadaulo wokhawokha wa laser, womwe umakhala wowononga, womwe suli wokhwima kwambiri ku China.Ili ndi vuto loyamba lomwe chip chimakumana nacho.
Vuto lachiwiri ndi kusasunthika kwa chipangizo cha Micro LED, chomwe chimakhala ndi mbali yayikulu kwambiri pakusasinthika kwa chipangizo cha Micro LED.Poyambirira, kachulukidwe kameneka mu GaN LED epitaxy inali yokwera kwambiri ngati 1010. Ngakhale kuti kusasunthikako kunali kwakukulu, kuwala kowala kunalinso kwakukulu.Pambuyo gallium nitride LED opangidwa ku Japan, patatha zaka zoposa 30 chitukuko, ndondomeko kukhathamiritsa wafika padenga, ndi kachulukidwe dislocation wafika 5 × 108.Komabe, chifukwa cha kachulukidwe kakachulukidwe kaukadaulo waukadaulo wa LED, kukula kwa Micro LED kumatha kulepheretsa kukula kwa zinthu zina.Chifukwa chake, kupitiliza ukadaulo wa chip wa LED womwe ulipo ndikupanga Micro LED kuyenera kuthana ndi mavuto awiri.Imodzi ndikuchepetsanso kusasunthika kwa zinthu za gallium nitride, ndipo ina ndiyopeza ukadaulo wokweza bwino kuposa ukadaulo wa laser lift-off.
