Ibisekuruza bizakurikiraho byerekana tekinoroji Micro LED yabaye intego yibanze muri uyu mwaka wa Touch Taiwan Smart Display.Hafunguwe umwaka wambere wa Micro LED umwaka ushize, abahinguzi bakomeye berekanye ibintu byinshi byo kwigana hamwe no kureba imbere muri uyu mwaka, kandi 2022 ntagushidikanya ko uzaba umwaka wingenzi nyuma yo gutangira.Hamwe niterambere ryiterambere ryikoranabuhanga, abakora Micro LED bakoze buhoro buhoro bambuka imisozi ibiri y "ikiguzi" n "" umusaruro ", kandi bahura n" "icyerekezo gishya" imbere ya Micro LED.
Micro LED inzira igabanijwe cyane cyane mu mikurire ya chip, gukora chip, inzira ya firime yoroheje, kwimura abantu benshi, kugenzura no gusana.Bitewe no gukuraho paki ya LED hamwe na substrate, usize firime epitaxial, chip ya Micro LED iroroshye, yoroheje kandi ngufi, itanga ubunini butandukanye bwerekana pigiseli.Mu gihe kimwe, Micro LED nayo iragwa ibyiza byaLED yerekana.
Ugereranije nuburyo busanzwe bwo gukora LED, intambwe zo gukura kwa Lei chip, gukora chip ya Micro LED, hamwe nuburyo bwo gukora firime yoroheje birashobora gukoreshwa kuriP1.56 byoroshye kuyobora byerekanwegukora gusa muguhindura ibikoresho, ariko biragoye kwimura, gutahura no gusana byinshi.Muri byo, kwimura abantu benshi, kugenzura no gusana, hamwe nubushobozi buke bwa Micro LED itukura ni inzitizi mu ikoranabuhanga rigezweho, kandi ni nurufunguzo rwo kugira ingaruka ku giciro no ku musaruro.Iyo ibyo bibazo bimaze gucika kandi ikiguzi kikagabanuka, habaho amahirwe yo kubyara umusaruro.tera imbere.
Imwe mu mbogamizi kuri "Horizons Nshya": Kwimura Misa
Kubera ko umubyimba wa epitaxial substrate ari munini kuruta ubunini bwa chip, Micro LED igomba kwimurwa cyane, chip irashishwa, igashyirwa kububiko bwigihe gito, hanyuma hanyumaMicro LEDyimuriwe kumurongo wanyuma wumuzunguruko cyangwa verisiyo ya TFT.Tekinoroji nyamukuru yo kwimura abantu benshi muriki cyiciro harimo guteranya amazi, kwimura lazeri, gutoranya no gukoresha ikoranabuhanga (Stamp Pick & Place), nibindi.
Tekinoroji yo gutoranya-ahantu ikoresha tekinoroji ya MEMS ikoreshwa muburyo bwa tekinoroji yo gutoranya-ahantu, ariko tekinoroji ya LED yo gutoranya-ahantu hamwe ifite igiciro kinini kubera igipimo cyayo cyo gutoranya-ahantu;kubijyanye no kwimura laser, Micro LEDs yihuta kandi nini yimuwe kuva substrate yumwimerere na laser beam Micro LED kugirango igabanye substrate.Yang Fubao, umusesenguzi muri TrendForce, yagaragaje ko ikoranabuhanga rya pikipiki gakondo ryagoye kubyara umusaruro mwinshi kubera umuvuduko waryo ndetse n’igiciro kinini mu bihe byashize.Kubwibyo, muri uyu mwaka, tekinoroji yagiye ihinduka buhoro buhoro kuva muri pikipiki gakondo ijya mu buhanga bwihuse kandi bwihuse.kwimura kugirango ufashe kugabanya ibiciro.Kubijyanye na tekinoroji yo guteranya amazi, hakoreshwa interineti ya capillary yagurishijwe yashizwemo, kandi amazi yo guhagarika amazi arashobora gukoreshwa nkigikoresho mugihe cyo guterana guhuza imashini n'amashanyarazi guhuza electrode, hanyuma bigahita bifata kandi bigahuza Micro LEDs hamwe nabagurisha. .Iterambere ryihuse rirashoboka.Vuba aha, Huawei yagiye ikoresha cyane tekinoroji ya Micro LED.Urebye amakuru yipatanti, birashoboka cyane gukoresha tekinoroji yo guteranya amazi.
"Inzira Nshya" Inzitizi No 2: Kumenya no gusana
Nubwo kwimura imbaga yamye ari urufunguzo rwumusaruro rusange, akamaro ko kugenzura no gusana ibyuma bya Micro LED ntabwo ari ngombwa nko kwimura abantu benshi.Kugeza ubu, uburyo bubiri bukoreshwa cyane mu nganda ni Photoluminescence (PL) na electroluminescence (EL).Ikiranga PL nuko ishobora kugeragezwa itabanje kuvugana cyangwa kwangiza chip ya LED, ariko ingaruka yikizamini ntabwo ari nziza nkiya EL;muburyo bunyuranye, EL irashobora kubona inenge nyinshi mugupima chip ya LED uyikoresha amashanyarazi, ariko irashobora kwangiza chip kubera guhura.
Byongeye kandi, chip ya Micro LED ni nto cyane kuburyo idakwiriye ibikoresho bisanzwe byo gupima.Hatitawe ku kuba ikizamini cya EL cyangwa PL cyakoreshejwe, hashobora kubaho ikibazo cyo kutamenya neza imikorere, kikaba ari igice kigomba kuneshwa.Kubijyanye no gusana, abakora Micro LED bakoresha tekinoroji yo gusana ultraviolet irrasiyoya, tekinoroji yo gusana laser, tekinoroji yo gutoranya gutoranya, tekinoroji yo gusana laser hamwe nibisubizo byubushakashatsi bwakorewe.
Inzitizi ya gatatu kuri "Horizons Nshya": Chip Micro Micro LED
Hanyuma, hari ibara ryerekana ubwaryo.Kuri Micro LEDs, ugereranije n'ubururu n'icyatsi, umutuku ni ibara rigoye cyane kwerekana, kandi igiciro ni kinini.Nitride semiconductor ikoreshwa muruganda kugirango itange ubururu nicyatsi Micro LED.LED LED itukura igomba kuvangwa na sisitemu yibikoresho byinshi cyangwa ikabyara semiconductor ya fosifide.
Nyamara, ikibazo cyibara ryibara rishobora kugaragara mugihe cya epitaxial.Gukomatanya ibikoresho bitandukanye bya semiconductor bizongera ingorane zumusaruro nigiciro cyo gukora cyamabara yuzuye ya LED LED.Inzira yo guca chip irashobora kandi kuganisha kumikorere mibi yumucyo, tutibagiwe nubunini bugabanuka., imikorere ya fosifike Micro LED chip izagabanuka cyane.Byongeye kandi, ibikoresho bivanze birakenewe mugikorwa cya semiconductor, bityo rero biragoye, bitwara igihe, bihenze, kandi umusaruro uragoye gutera imbere.
Kubwibyo, ababikora bamwe bateye imbere bava mubikoresho ubwabyo.Kurugero, Porotech, isosiyete ya Micro LED, yasohoye nitride ya mbere ya indium gallium nitride (InGaN) ishingiye ku itara ritukura-Micro LED yerekana, bivuze ko ubwoko butatu bwerekana bwerekana InGaN nkibikoresho byerekana, bitagarukira kuri kimwe. substrate.Byongeye kandi, JBD, uruganda rukomeye rwa Micro LED, yiyemeje gukoresha ikoranabuhanga ritukura rya Micro LED rishingiye kuri AlGaInP mu bihe byashize, kandi iherutse gutangaza ko rimaze kugera kuri 500.000 nits y’umucyo mwinshi cyane utukura Micro LED.
Nubwo twatangiye umwaka wambere wa Micro LED, ibibazo byinshi biracyakeneye igihe cyo gukemurwa buhoro.Kuri ubu, twabonye intangiriro yo gusaba.Byizerwa ko nyuma yinzitizi nko kwimura abantu benshi, kugenzura no kubungabunga, hamwe nubushobozi bwo kumurika byatsinzwe umwe umwe, biteganijwe ko Micro LED izagerwaho.Kwamamaza, mugihe kizaza, porogaramu zizanwa na Micro LED zirashobora kugaragara mumashusho yimodoka, ecran nini yerekana, ibikoresho bya AR / VR,hejuru-yerekana neza kuyoboraibicuruzwa bishobora kwambara, nibindi
