MicroLED ndi mtundu wa kuwala emitting diode (LED), makamaka zosakwana 100μm kukula kwake.Miyeso wamba ndi yochepera 50 μm, ndipo ena ndi ang'onoang'ono ngati 3-15 μm.Pankhani ya sikelo, ma MicroLED ndi pafupifupi 1/100 kukula kwa LED wamba komanso pafupifupi 1/10 m'lifupi mwa tsitsi la munthu.Mu chiwonetsero cha MicroLED, pixel iliyonse imayankhulidwa payekha ndikuyendetsedwa kuti ipereke kuwala popanda kufunikira kowunikira.Amapangidwa ndi zinthu zopanda pake, zomwe zimapereka moyo wautali wautumiki.
PPI ya MicroLED ndi 5,000 ndipo kuwala ndi 105nit.PPI ya OLED ndi 3500, ndipo kuwala ndi ≤2 x 103nit.Monga OLED, ubwino wa MicroLED ndi kuwala kwakukulu, kugwiritsira ntchito mphamvu zochepa, kusamvana kwakukulu kwambiri komanso kutulutsa mtundu.Ubwino waukulu wa MicroLED umachokera ku mawonekedwe ake akuluakulu, mayendedwe a micron-level.Pixel iliyonse imatha kuthana ndi kuwongolera ndikuyendetsa kwa mfundo imodzi kuti ipereke kuwala.Poyerekeza ndi ma LED ena, MicroLED pakali pano ili pamwamba kwambiri potengera mphamvu zowunikira komanso kachulukidwe kamphamvu, ndipo pali malo oti asinthe.Ndi zabwino kwaflexible LED chiwonetsero.Chotsatira chamakono chamakono ndi chakuti, poyerekeza MicroLED ndi OLED, kuti mukwaniritse kuwala kofananako, pafupifupi 10% yokha ya malo okutira omaliza amafunikira.Poyerekeza ndi OLED, yomwe imakhalanso yodziwonetsera yokha, kuwalako ndi 30 nthawi zambiri, ndipo chisankhocho chikhoza kufika ku 1500PPI, yomwe ili yofanana ndi 5 nthawi 300PPI yogwiritsidwa ntchito ndi Apple Watch.
Popeza MicroLED imagwiritsa ntchito zida zamkati ndipo ili ndi mawonekedwe osavuta, imakhala yopanda kuwala.Utumiki wake ndi wautali kwambiri.Izi sizingafanane ndi OLED.Monga zinthu zakuthupi, OLED ili ndi zolakwika zake - moyo wautali komanso kukhazikika, zomwe ndizovuta kuziyerekeza ndi QLED ndi MicroLED zazinthu zopanda chilengedwe.Amatha kutengera kukula kosiyanasiyana.Ma MicroLED amatha kuikidwa pazigawo zosiyanasiyana monga galasi, pulasitiki, ndi zitsulo, zomwe zimathandiza kuti ziwonetsedwe zosinthika, zopindika.
Pali malo ambiri ochepetsera mtengo.Pakalipano, teknoloji ya micro-projection imafuna kugwiritsa ntchito gwero la kuwala kwakunja, zomwe zimapangitsa kuti zikhale zovuta kupititsa patsogolo kukula kwa gawoli, ndipo mtengo wake ndi wapamwamba.Mosiyana ndi izi, mawonekedwe odziwonetsera okha a MicroLED microdisplay safuna kuwala kwakunja, ndipo mawonekedwe a kuwala ndi osavuta.Chifukwa chake, ili ndi zabwino mu miniaturization ya volume ya module ndi kuchepetsa mtengo.
M'kanthawi kochepa, msika wa Micro-LED umayang'ana kwambiri zowonetsera zazing'ono.Pakatikati ndi nthawi yayitali, magawo ogwiritsira ntchito a Micro-LED ndi otakata kwambiri.Pazida zonse zovala, zowonetsera zazikulu zamkati, zowonekera pamutu (HUD), nyali zam'mbuyo, kulumikizana opanda zingwe za Li-Fi, AR/VR, mapurojekitala ndi magawo ena.
Mfundo yowonetsera ya MicroLED ndikuwonda, kuchepetsa ndi kuyika mapangidwe a LED.Kukula kwake ndi pafupifupi 1 ~ 10μm.Pambuyo pake, ma MicroLED amasamutsidwa ku magawo ozungulira m'magulu, omwe amatha kukhala olimba kapena osinthika owonekera kapena opaque.Kuwonekera kwa LEDndi zabwinonso.Kenako, gawo lotetezera ndi electrode yapamwamba imatsirizidwa ndi ndondomeko yowonongeka kwa thupi, ndiyeno gawo lapansi lapamwamba likhoza kuikidwa kuti likwaniritse chiwonetsero cha MicroLED ndi dongosolo losavuta.
Kuti apange chiwonetsero, pamwamba pa chip chiyenera kupangidwa kukhala chofanana ndi chiwonetsero cha LED, ndipo pixel iliyonse yamadontho iyenera kukhala yokhoza kulumikizidwa ndi kuwongolera ndikuyendetsedwa payekhapayekha kuti iwunikire.Ngati imayendetsedwa ndi chitsulo chothandizira oxide semiconductor circuit, ndi njira yoyendetsera galimoto, ndipo teknoloji yonyamula katundu imatha kudutsa pakati pa MicroLED array chip ndi CMOS.
phala likamalizidwa, MicroLED imatha kuwongolera kuwala ndi kusiyanitsa mwa kuphatikiza ma microlens.Gulu la MicroLED limalumikizidwa ndi ma elekitirodi abwino ndi oyipa a MicroLED iliyonse kudzera mu ma elekitirodi owoneka bwino komanso oyipa, ndipo ma elekitirodi amapatsidwa mphamvu motsatizana, ndipo ma MicroLED amayatsidwa ndi sikani kuti awonetse zithunzi.
Monga cholumikizira chomwe chikubwera pamsika, Micro LED ili ndi njira yovuta yomwe mafakitale ena amagetsi sagwiritsa ntchito kawirikawiri - kutumiza anthu ambiri.Kusamutsa anthu ambiri kumawonedwa ngati chinthu chachikulu chomwe chimakhudza kuchuluka kwa zokolola ndi kutulutsa mphamvu, komanso ndi malo omwe opanga zazikulu amayang'ana kwambiri kuthana ndi zovuta.Pakalipano, pali mayendedwe osiyanasiyana panjira yaukadaulo, ndiye kutengerapo kwa laser, ukadaulo wodzipangira okha komanso ukadaulo wosinthira.
Kodi ukadaulo wamtundu wanji ndi "mass transfer"?Kunena mophweka, pa gawo la TFT dera laling'ono kukula kwa msomali, malinga ndi zofunikira za optics ndi magetsi, mazana atatu mpaka asanu kapena ochulukirapo ofiira, obiriwira ndi abuluu a LED amapangidwa mofanana.
Kulephera kovomerezeka ndi 1 pa 100,000.Zogulitsa zokhazokha zomwe zimakwaniritsa njirayi zingagwiritsidwe ntchito mowona ku zinthu monga Apple Watch 3. Tekinoloje ya pamwamba pa phiri tsopano yapeza teknoloji yopititsa patsogolo teknoloji mu MINI LED, koma ikufunika kutsimikiziridwa kothandiza pakupanga kwa MicroLED.
NgakhaleMawonekedwe a MicroLEDndi okwera mtengo kwambiri poyerekeza ndi mapanelo ochiritsira a LCD ndi OLED, ubwino wawo pakuwala ndi kuwongolera mphamvu kumawapangitsa kukhala njira yowoneka bwino pamapulogalamu ang'onoang'ono komanso akulu kwambiri.Pakapita nthawi, njira yopangira MicroLED idzalola ogulitsa kuchepetsa ndalama zopangira.Njirayi ikafika pakukula, malonda a MicroLED ayamba kukwera.Kuti tiwonetsere izi, pofika chaka cha 2026, mtengo wopangira ma 1.5-inch microLED mawotchi anzeru akuyembekezeka kutsika mpaka gawo limodzi mwa magawo khumi amtengo wapano.Panthawi imodzimodziyo, mtengo wopangira chiwonetsero cha TV cha 75-inch udzatsikira ku gawo limodzi mwa magawo asanu a mtengo wake wamakono pa nthawi yomweyo.
M'zaka ziwiri zapitazi, makampani a Mini Led adzalowa m'malo mwaukadaulo wamakono.Mu 2021, makampani owonetsera zamagetsi monga mawonedwe a galimoto, zowonetsera zipangizo zapakhomo, zowonetsera misonkhano, zowonetsera chitetezo ndi mafakitale ena owonetsera zamagetsi zidzayambitsa chiwonongeko chambiri ndikupitirizabe mpaka teknoloji yopanga zazikulu za Micro LED itakhazikika.
