MicroLED ni ubwoko bwurumuri rusohora diode (LED), mubusanzwe munsi ya 100 mm.Ingano isanzwe iri munsi ya 50 mm, kandi zimwe ni ntoya nka 3-15 mm.Ukurikije igipimo, MicroLEDs zingana na 1/100 kingana na LED isanzwe hamwe na 1/10 cy'ubugari bwimisatsi yumuntu.Muri MicroLED yerekana, buri pigiseli yandikirwa kugiti cye kandi ikayoborwa kugirango isohore urumuri bidakenewe itara ryinyuma.Byakozwe mubikoresho bidasanzwe, bitanga ubuzima burebure.
PPI ya MicroLED ni 5.000 naho umucyo ni 105nit.PPI ya OLED ni 3500, kandi umucyo ni ≤2 x 103nit.Kimwe na OLED, ibyiza bya MicroLED ni umucyo mwinshi, gukoresha ingufu nke, ultra-high resolution hamwe no kwiyuzuza amabara.Inyungu nini ya MicroLED iva mubiranga binini, ikibuga cya micron.Buri pigiseli irashobora gukemura igenzura hamwe ningingo imwe yo gusohora urumuri.Ugereranije nizindi LED, MicroLED kuri ubu iri hejuru cyane mubijyanye no gukora neza nubucucike bwingufu, kandi haracyariho iterambere.Nibyiza kuriLED yerekana.Igisubizo kigezweho ni uko, ugereranije MicroLED na OLED, kugirango ugere kumurongo umwe wo kwerekana, gusa 10% byubuso bwaho busabwa.Ugereranije na OLED, nayo ikaba yerekana-kwiyerekana, umucyo wikubye inshuro 30, kandi imyanzuro irashobora kugera kuri 1500PPI, ibyo bikaba bihwanye ninshuro 5 300PPI yakoreshejwe na Apple Watch.
Kubera ko MicroLED ikoresha ibikoresho bidasanzwe kandi ifite imiterere yoroshye, ntabwo ikoresha urumuri.Ubuzima bwa serivisi ni ndende cyane.Ibi ntagereranywa na OLED.Nkibintu kama, OLED ifite inenge-ubuzima bwayo nigihe gihamye, biragoye kugereranya na QLED na MicroLED yibikoresho kama.Bashoboye guhuza nubunini butandukanye.MicroLEDs irashobora kubikwa kubutaka butandukanye nk'ikirahure, plastike, nicyuma, bigafasha kwerekana ibintu byoroshye.
Hano hari ibyumba byinshi byo kugabanya ibiciro.Kugeza ubu, tekinoroji ya micro-projection isaba gukoresha isoko yumucyo wo hanze, bigatuma bigora kurushaho kugabanya ingano ya module, kandi ikiguzi nacyo kiri hejuru.Ibinyuranye, microdisplay ya MicroLED yo kumurika ntabwo isaba isoko yumucyo wo hanze, kandi sisitemu ya optique iroroshye.Kubwibyo, ifite ibyiza muri miniaturizasi yubunini bwa module no kugabanya ibiciro.
Mugihe gito, isoko rya Micro-LED ryibanze kuri ultra-nto yerekana.Mugihe giciriritse nigihe kirekire, imirima yo gusaba ya Micro-LED ni ngari cyane.Hafi y'ibikoresho byambarwa, ibyerekanwa binini byo mu nzu, kwerekana imitwe (HUDs), amatara, itumanaho rya optique Li-Fi, AR / VR, umushinga nizindi nzego.
Ihame ryo kwerekana MicroLED ni kunanura, kugabanya no gutondekanya imiterere ya LED.Ingano yacyo ni nka 1 ~ 10 mm gusa.Nyuma yibyo, MicroLEDs yimuriwe kumurongo wumuzunguruko mubice, bishobora kuba bikomeye cyangwa byoroshye gukorera mu mucyo cyangwa kutagaragara.LED yerekana nezani byiza kandi.
Kugirango ukore ibyerekanwa, ubuso bwa chip bugomba gukorwa muburyo bwimiterere nka LED yerekana, kandi buri kadomo pigiseli igomba kuba ikemurwa kandi igenzurwa kandi kugiti cye kugiti cye.Niba itwarwa nicyuma cyuzuzanya cyicyuma cya semiconductor, ni uburyo bukoreshwa muburyo bwo gutwara ibinyabiziga, kandi tekinoroji yo gupakira irashobora kunyuzwa hagati ya MicroLED chip chip na CMOS.
Iyo paste irangiye, MicroLED irashobora kunoza umucyo no gutandukanya muguhuza microlens array.MicroLED array ihujwe na electrode nziza kandi mbi ya buri MicroLED ikoresheje vertike ihindagurika neza ya electrode nziza kandi mbi, kandi electrode ikongerwamo ingufu mukurikirane, naho MicroLEDs ikamurikirwa na scan kugirango yerekane amashusho.
Nkumuhuza ugaragara murwego rwinganda, Micro LED ifite inzira igoye izindi nganda za elegitoroniki zidakunze gukoresha-kwimura abantu.Iyimurwa rusange rifatwa nkibyingenzi bigira ingaruka ku gipimo cy’umusaruro no kurekura ubushobozi, kandi ni n’ahantu abakora inganda zikomeye bibanda ku gukemura ibibazo bikomeye.Kugeza ubu, hari icyerekezo gitandukanye munzira ya tekiniki, aribyo kwimura laser, tekinoroji yo guteranya hamwe na tekinoroji yo kwimura.
Ni ubuhe bwoko bw'ikoranabuhanga "kwimura abantu benshi"?Tubivuze mu buryo bworoshe, kumuzunguruko wa TFT ugereranya ubunini bw'urutoki, ukurikije ibisobanuro bikenewe bya optique n'amashanyarazi, magana atatu kugeza kuri magana atanu cyangwa arenga umutuku, icyatsi n'ubururu LED micro-chip irasudira neza.
Igipimo cyemewe cyo kunanirwa ni 1 kuri 100.000.Gusa ibicuruzwa bigera kubikorwa nkibi birashobora gukoreshwa mubyukuri kubicuruzwa nka Apple Watch 3. Ikoranabuhanga rya Surface mount ryageze ku musaruro w’ikoranabuhanga rya transfert muri MINI LED, ariko rikeneye kugenzurwa mubikorwa bya MicroLED.
NubwoMicroLED yerekanabihenze cyane ugereranije nibisanzwe LCD na OLED, ibyiza byabo mumucyo no gukoresha ingufu bituma bakora ubundi buryo bushimishije muri ultra-nto kandi nini cyane.Igihe kirenze, uburyo bwo gukora MicroLED buzafasha abatanga ibicuruzwa kugabanya ibicuruzwa.Ibikorwa nibimara gukura, MicroLED igurisha izatangira kwiyongera.Kugira ngo tugaragaze iki cyerekezo, mu 2026, igiciro cyo gukora cya santimetero 1.5 ya microLED yerekana amasaha yubwenge giteganijwe kugabanuka kugeza ku icumi cyikiguzi kiriho.Muri icyo gihe, ikiguzi cyo gukora TV ya 75-yerekana TV kizagabanuka kugera kuri kimwe cya gatanu cyikiguzi cyacyo mugihe kimwe.
Mu myaka ibiri ishize, inganda za Mini Led zizasimbuza vuba tekinoroji gakondo yo kwerekana.Mu 2021, inganda zerekana ibikoresho bya elegitoronike nko kwerekana ibinyabiziga, kwerekana ibikoresho byo mu rugo, kwerekana inama, kwerekana umutekano ndetse n’inganda zerekana ibyuma bya elegitoronike bizagaba igitero rusange kandi bikomeze kugeza ubwo ikoranabuhanga rya Micro LED rikora neza.
