MicroLED imhando yemwenje emitting diode (LED), kazhinji isingasviki 100μm muhukuru.Saizi dzakajairwa dziri pasi pe50 μm, uye dzimwe dzakatodiki se3-15 μm.Panyaya yechiyero, MicroLEDs inenge 1/100 saizi yeyakajairwa LED uye inenge 1/10 hupamhi hwebvudzi remunhu.Muchiratidziro cheMicroLED, pixel yega yega inotariswa uye inofambiswa kuti ibudise mwenje pasina kudiwa kwebacklight.Izvo zvakagadzirwa nezvinhu zvisingasviki, izvo zvinopa hupenyu hurefu hwebasa.
Iyo PPI yeMicroLED i5,000 uye kupenya kuri 105nit.Iyo PPI yeOLED i3500, uye kupenya kuri ≤2 x 103nit.Kufanana neOLED, zvakanakira MicroLED kupenya kwakanyanya, kuderera kwesimba rekushandisa, yekupedzisira-yepamusoro resolution uye kuzara kwemavara.Mukana wakakurisa weMicroLED unobva pachinhu chayo chikuru, iyo micron-level pitch.Pixel yega yega inogona kugadzirisa kutonga uye imwe-point drive kuburitsa mwenje.Kana ichienzaniswa nemamwe maLED, MicroLED parizvino iri pakakwirira maererano nekupenya kwakanaka uye kupenya kwesimba remagetsi, uye pachine nzvimbo yekuvandudza.Yakanakiraflexible LED kuratidza.Mhedzisiro yezvino mhedzisiro ndeyekuti, kuenzanisa MicroLED neOLED, kuti uwane kupenya kwakafanana kwekuratidzira, ingangoita 10% yenzvimbo yekupfekedza yekupedzisira inodiwa.Kuenzaniswa neOLED, inovawo inozvivhenekera, kupenya kwakapetwa ka30, uye sarudzo inogona kusvika ku1500PPI, iyo yakaenzana ne5 times the 300PPI inoshandiswa neApple Watch.
Sezvo MicroLED inoshandisa inorganic zvinhu uye ine chimiro chakareruka, inenge isina kushandiswa kwechiedza.Hupenyu hwesevhisi hwayo hwakareba kwazvo.Izvi hazvienzaniswi neOLED.Sezvinhu zvehupenyu, OLED ine hurema hwayo hwekuzvarwa-hupenyu uye kugadzikana, izvo zvakaoma kuenzanisa neQLED uye MicroLED yezvisingaverengeki zvinhu.Kukwanisa kuenderana nehukuru hwakasiyana.MicroLEDs inogona kuiswa pane akasiyana substrates akadai segirazi, plastiki, uye simbi, zvichiita kuchinjika, bendable kuratidza.
Pane nzvimbo yakawanda yekudzikisa mutengo.Parizvino, iyo micro-projection tekinoroji inoda kushandiswa kwekunze kwechiedza sosi, izvo zvinoita kuti zviome kuwedzera kudzikisa ukuru hwemodule, uye mutengo wakakwira zvakare.Kusiyana neizvi, iyo-inovhenekera MicroLED microdisplay haidi yekunze mwenje sosi, uye optical system iri nyore.Naizvozvo, ine zvakanakira mune miniaturization yemodule vhoriyamu uye kuderedza mutengo.
Munguva pfupi, iyo Micro-LED musika inotariswa pane ekupedzisira-madiki kuratidza.Munguva yepakati uye kwenguva refu, iyo minda yekushandisa yeMicro-LED yakakura kwazvo.Pakati pemidziyo inopfekwa, masikirini mahombe emukati, madhizaini akaiswa mumusoro (HUDs), maraiti emushure, mawireless optical kutaurirana Li-Fi, AR/VR, mapurojekita nemimwe minda.
Nheyo yekuratidzira yeMicroLED ndeyekutetepa, kuita diki uye kurongedza iyo LED chimiro dhizaini.Saizi yaro ndeye 1 ~ 10μm chete.Mushure mezvo, maMicroLED anotamirwa kumatunhu ematunhu mumabhechi, ayo anogona kuomarara kana kuchinjika akajeka kana opaque substrates.Transparent LED kuratidzazvakare yakanaka.Zvino, iyo inodzivirira layer uye yekumusoro electrode inopedzwa neiyo yemuviri deposition process, uye ipapo iyo yepamusoro substrate inogona kuiswa mukati kuti ipedze MicroLED kuratidzwa ine nyore chimiro.
Kuti ugadzire chiratidziro, pamusoro peiyo chip inofanira kugadzirwa kuita dhizaini senge LED kuratidza, uye yega yega pixel dot inofanirwa kugadzirika uye inodzoreka uye yega yega kuti ivheneke.Kana ichifambiswa neinopindirana simbi oxide semiconductor wedunhu, iri inoshanda kugadzirisa dhiraivha chimiro, uye yekurongedza tekinoroji inogona kupfuudzwa pakati peiyo MicroLED array chip neCMOS.
Mushure mekunge paste yapera, iyo MicroLED inogona kuvandudza kupenya uye kusiyanisa nekubatanidza iyo microlens array.Iyo MicroLED array yakabatana kune yakanaka uye yakaipa electrode yeMicroLED yega yega kuburikidza ne vertically staggered positive and negative grid electrodes, uye ma electrode anosimbiswa mukutevedzana, uye maMicroLED anovhenekera nekuongorora kuti aratidze mifananidzo.
Sechinhu chinobuda muindastiri ketani, Micro LED ine maitiro akaoma ayo mamwe maindasitiri emagetsi asingawanzo shandisa-kufambiswa kwevanhu vakawanda.Kufambiswa kwemisa kunoonekwa sechinhu chakakosha chinokanganisa chiyero chegoho uye kuburitswa kwesimba, uye zvakare inzvimbo iyo vagadziri vakuru vanotarisa kugadzirisa matambudziko akaomarara.Parizvino, kune nzira dzakasiyana siyana panzira yehunyanzvi, iyo inonzi laser transfer, self-assembly tekinoroji uye tekinoroji yekufambisa.
Imhando ipi yetekinoroji inonzi "mass transfer"?Kuzvitaura zviri nyore, paTFT redunhu substrate saizi yechigunwe, zvinoenderana nezvinodiwa zveoptics nemagetsi, mazana matatu kusvika mashanu kana kutopfuura matsvuku, girini uye bhuruu LED ma micro-chips akabatanidzwa zvakaenzana.
Iyo inobvumirwa process yekutadza mwero ndeye 1 mu100,000.Zvigadzirwa chete zvinowana nzira yakadaro zvinogona kushandiswa zvechokwadi kune zvigadzirwa zvakadai seApple Watch 3. Surface mount teknolojia yave yawana mass transfer technology kugadzirwa muMINI LED, asi inoda kuongororwa kunoshanda mukugadzirwa kweMicroLED.
NyangweMicroLED inoratidzainodhura zvakanyanya kana ichienzaniswa neyakajairwa LCD neOLED mapaneru, zvakanakira kupenya uye kugona kwesimba zvinoita kuti ive imwe inoyevedza imwe nzira muultra-diki uye yakakura kwazvo maapplication.Nokufamba kwenguva, iyo MicroLED yekugadzira maitiro ichabvumira vatengesi kuderedza mari yekugadzira.Kamwe maitiro acho asvika pakukura, MicroLED kutengesa kunotanga kukwira.Kuenzanisira maitiro aya, panosvika 2026, mutengo wekugadzira we 1.5-inch microLED kuratidza kwema smartwatches unotarisirwa kudonha kusvika pachikamu chegumi chemutengo wazvino.Panguva imwecheteyo, mutengo wekugadzira we75-inch TV inoratidzira ichadonha kusvika kune chimwe cheshanu chemutengo wayo wazvino panguva imwe chete.
Mumakore maviri apfuura, iyo Mini Led indasitiri ichakurumidza kutsiva yechinyakare yekuratidzira tekinoroji.Muna 2021, indasitiri yekuratidzira yemagetsi yakadai sekuratidzira kwemotokari, kuratidzwa kwemidziyo yemumba, kuratidzwa kwemusangano, kuratidzwa kwekuchengetedza uye mamwe maindasitiri ekuratidzira emagetsi achatanga kurwisa kwakawanda uye kuenderera mberi kusvika Micro LED misa yekugadzira tekinoroji yagadzikana.
