Tiknoolajiyada soo-bandhigidda ee Micro LED waxay noqotay diiradda ugu weyn ee sannadkan Bandhigga Bandhigga Smart Taiwan Touch.Furitaanka sanadka ugu horreeya ee Micro LED sannadkii hore, soo-saareyaasha waaweyni waxay muujiyeen xaalado jilitaan badan iyo codsiyo mustaqbalka leh sannadkan, iyo 2022 shaki la'aan waxay noqon doontaa sannad muhiim ah ka dib bilowga.Iyada oo horumarka joogtada ah ee tignoolajiyada, saarayaasha Micro LED ayaa si tartiib tartiib ah uga gudbey labada buurood ee "qiimaha" iyo "wax-soo-saarka", waxayna wajahayaan "horumarka cusub" ee indhaha Micro LED.
Habka Micro LED waxaa inta badan loo qaybiyaa kobaca chip, soo saarista chip, habka filim khafiif ah, wareejin ballaaran, kormeerka iyo dayactirka.Sababtoo ah ka saarista xirmada LED-ka iyo substrate-ka, ka tagaya filimka epitaxial, Chip Micro LED waa khafiif, khafiif ah oo gaaban, oo bixiya noocyo kala duwan oo cabbir ah pixels. Isla mar ahaantaana, Micro LED sidoo kale waxay dhaxlaan faa'iidooyinkaMuujinta LED, oo leh xallin sare, dhalaal sare, nolol dheer, gamut midabka ballaaran, sifooyinka is-iftiinka, isticmaalka awoodda hoose, iyo xasilloonida deegaanka, oo ku habboon codsiyada soo-bandhigidda casriga ah ee mustaqbalka, Sida baabuurta, muraayadaha AR, qalabyada xiran, iwm.
Marka la barbar dhigo habka wax soo saarka LED dhaqameed, tillaabooyinka koritaanka Lei chip, Micro LED chip soo saarista, iyo habka wax soo saarka filim khafiif ah ayaa loo isticmaali karaaP1.56 muraayad dabacsanwax soo saarka oo kaliya iyadoo wax laga beddelayo qalabka, laakiin way adag tahay in la wareejiyo, la ogaado oo la dayactiro tiro badan.Waxaa ka mid ah, wareejinta ballaaran, kormeerka iyo dayactirka, iyo hufnaanta iftiinka ee Micro LED-ka casaanka ah ayaa ah caqabadaha tignoolajiyada hadda jira, waxayna sidoo kale fure u yihiin inay saameeyaan qiimaha iyo wax-soo-saarka.Marka dhibaatooyinkaas la jebiyo oo kharashka la yareeyo, waxaa jirta fursad ah in wax soo saar ballaaran la sameeyo.hore u soco.
Mid ka mid ah caqabadaha hortaagan "New Horizons": Wareejinta Mass
Maaddaama dhumucda substrate-ka epitaxial ay ka weyn tahay cabbirka chip-ka, Micro LED waa in si ballaaran loo wareejiyaa, jajabku waa la diiray, lagu dhejiyaa substrate-ka kaydinta ku-meel-gaarka ah, ka dibnaMicro LEDwaxaa loo wareejiyaa guddiga wareegga ugu dambeeya ama nooca TFT.Tignoolajiyada wareejinta tirada badan ee marxaladan waxaa ka mid ah isu-ururinta dareeraha, wareejinta laysarka, tignoolajiyada soo qaadida iyo meelaynta (Stamp Pick&Place), iwm.
Tiknoolajiyada soo-qaadista iyo goobta waxay isticmaashaa tignoolajiyada diyaarinta MEMS ee tignoolajiyada soo-qaadista-iyo-meelaynta, laakiin tignoolajiyada soo-qaadista-iyo-goobta ee LED-ku waxay leedahay kharash aad u sarreeya sababtoo ah heerka soo-qaadista-iyo-goobta gaabiska ah;sida wareejinta laysarka, Micro LEDs si dhakhso ah oo baaxad leh ayaa looga wareejinayaa substrate-ka asalka ah ee laydhka laysarka Micro LED si loo beegsado substrate.Yang Fubao, oo ah falanqeeye ka tirsan TrendForce, ayaa tilmaamay in tignoolajiyada soo-qaadista dhaqameed ay adkeyd in la soo saaro tiro badan sababtoo ah xawaaraheeda gaabis ah iyo qiimaha sare ee hore.Sidaa darteed, sanadkan, tignoolajiyada ayaa si tartiib tartiib ah uga soo guurtay soo-qaadistii dhaqameed ilaa tignoolajiyada sare ee saxda ah oo degdeg ah.wareejinta si ay gacan uga geysato dhimista kharashaadka.Marka loo eego tikniyoolajiyadda dareeraha dareeraha, is-dhexgalka koofiyadda alxanka dhalaalaysa ayaa loo isticmaalaa, dareeraha joojinta dareeraha waxaa loo isticmaali karaa dhexdhexaad inta lagu jiro kulanka si farsamaysan iyo koronto loogu xiro korantada, isla markaana si dhakhso ah u qabso oo u waafajiso Micro LEDs-yada kala-goysyada alxanka. .Isku imaatinka xawaaraha sare waa suurtagal.Dhawaan, Huawei waxay si firfircoon u daabulaysay tignoolajiyada Micro LED.Marka loo eego macluumaadka patent-ka, waxay u badan tahay in la isticmaalo tignoolajiyada isu-ururinta dareeraha.
"Heerka Cusub" Caqabadda No. 2: Ogaanshaha iyo Dayactirka
In kasta oo wareejinta ballaaran ay had iyo jeer ahayd furaha wax soo saarka ballaaran, muhiimadda kormeerka xiga iyo dayactirka chips Micro LED waa mid aan ka muhiimsaneyn wareejinta ballaaran.Waqtigan xaadirka ah, labada hab ee inta badan loo isticmaalo warshadaha waa photoluminescence (PL) iyo electroluminescence (EL).Dabeecadda PL waa in la tijaabin karo iyada oo aan lala xiriirin ama aan waxyeello u geysan chip LED, laakiin saameynta tijaabadu uma fiicna sida EL;liddi ku ah, EL waxay heli kartaa cillado badan iyadoo tijaabinaysa chip LED by koronto, laakiin waxaa laga yaabaa in ay sababto dhaawac chip sababtoo ah xiriirka.
Intaa waxaa dheer, chip-ka Micro LED aad ayuu u yar yahay si uu ugu habboonaado qalabka tijaabada dhaqameed.Iyada oo aan loo eegin in tijaabada EL ama PL la isticmaalo, waxaa jiri kara xaalad ah hufnaan ogaanshaha liidata, taas oo ah qayb u baahan in laga gudbo.Sida qaybta dayactirka, soosaarayaasha Micro LED waxay isticmaalaan tignoolajiyada dayactirka iftiinka ultraviolet, tignoolajiyada dayactirka dhalaalka laysarka, tignoolajiyada dayactirka xulashada, tignoolajiyada dayactirka leysarka ee xulashada iyo xalalka naqshadaynta wareegga wareegga.
Caqabadda saddexaad ee "New Horizons": Red Micro LED Chips
Ugu dambeyntii, waxaa jira midabka muuqaalka laftiisa.Micro LEDs, marka loo eego buluugga iyo cagaarka, casaanku waa midabka ugu adag in la muujiyo, kharashkuna waa mid aad u sarreeya.Nitride semiconductors ayaa hadda loo isticmaalaa warshadaha si ay u soo saaraan Micro LEDs buluug iyo cagaaran.Casaan Micro LEDs waa in lagu qaso habab kala duwan ama lagu soo saaro semiconductors fosfide.
Si kastaba ha ahaatee, dhibaatada labbiska midabka ayaa laga yaabaa inay dhacdo inta lagu jiro habka epitaxial.Isku darka agabyada semiconductor ee kala duwan ayaa kordhin doona dhibaatada wax soo saarka iyo qiimaha wax soo saarka ee midabada buuxa ee Micro LEDs.Habka jarista jajabyada waxay sidoo kale u horseedi kartaa waxtarka iftiinka oo liita, iyada oo aan la xusin xajmiga yaraanta., waxtarka phosphide Micro LED chips si weyn ayaa loo dhimi doonaa.Intaa waxaa dheer, qalab isku dhafan ayaa looga baahan yahay habka semiconductor, sidaas darteed waa mid adag, waqti-qaadasho, qaali ah, iyo wax-soo-saarku way adagtahay in la hagaajiyo.
Sidaa darteed, qaar ka mid ah soo-saarayaasha ayaa ka soo fiicnaaday walxaha laftiisa.Tusaale ahaan, Porotech, oo ah shirkad Micro LED ah, ayaa sii daysay muraayaddii ugu horreysay ee indium gallium nitride (InGaN) ee ku salaysan iftiinka Micro LED, taas oo macnaheedu yahay in dhammaan saddexda nooc ee bandhigyadu ay u isticmaalaan InGaN sida alaabta bandhigga, taas oo aan ku xaddidnayn wax kasta. substrate.Intaa waxaa dheer, JBD, oo ah soo saaraha weyn ee Micro LED, ayaa ka go'an AlGaInP-ku-saleysan tignoolajiyada Micro LED-ka ee la soo dhaafay, waxaana dhawaan lagu dhawaaqay in ay gaartay 500,000 nits oo ah wax soo saarka gaduudka sare ee iftiinka sare ee Micro LED.
In kasta oo aan ushered in sanadka ugu horeeya ee Micro LED, dhibaatooyin badan ayaa weli u baahan waqti in la xaliyo si tartiib ah.Hadda, waxaan aragnay bilowga codsiga.Waxaa la rumeysan yahay in ka dib dhalooyinka sida wareejinta ballaaran, kormeerka iyo dayactirka, iyo hufnaanta iftiinka laga gudbo mid mid, Micro LED ayaa la filayaa in la xaqiijiyo.Ganacsiga, mustaqbalka, codsiyada ay keentay Micro LED waxaa lagu arki karaa muraayadaha baabuurta, muraayadaha bandhigyada waaweyn, qalabka AR / VR,muujinta hogaanka sarealaab la gashado, iwm.
