Micro LED tau suav tias yog "qhov kawg zaub" kev daws teeb meem, thiab nws cov kev cia siab rau daim ntawv thov thiab tus nqi nws tuaj yeem tsim tau zoo heev.Cov ntawv thov tshiab xws li cov khoom lag luam, TVs siab kawg, tsheb thiab cov khoom siv coj los siv txuas ntxiv mus ua kom muaj kev loj hlob zoo, thiab cov kev lag luam sab saud thiab qis qis tau hloov kho cov duab ecosystem.
iav raws liMicro LED zaubmuaj kev ua tau zoo heev thiab ntau yam kev ua haujlwm, thiab xav tias yuav siv dav hauv cov khoom lag luam, TVs siab, tsheb, thiab hnav, nrog rau kev lag luam loj loj.Ntxiv cov cuab yeej tshiab thiab cov ntaub ntawv yuav dhau los ua lub sijhawm tseem ceeb rau kev tsim kho kev lag luam, thiab xav tias yuav hloov kho cov khoom lag luam ecosystem.Micro LED tuaj yeem paub qhov loj-loj dawb splicing zaub daim ntawv thov, thiab thev naus laus zis xws li cov ntim khoom ntim thiab cov kab thaiv phab ntsa ua kom dawb splicing tau.Micro LED tseem tuaj yeem paub txog daim ntawv thov kev sib tham sib koom ua ke.Lub vijtsam ntawm lub neej yav tom ntej yuav tsum dhau los ua lub platform, uas tuaj yeem paub txog ntau yam haujlwm xws li kev sib cuam tshuam los ntawm cov sensors, thiab tawg los ntawm lub tswvyim ntawm "duab".
Kev tsim kho tshiab ntawm qib cuab yeej tuaj yeem ua rau muaj kev hloov pauv ntawm qib ua haujlwm.Nrog 3D zaub, 3D kev sib cuam tshuam, thiab cov thev naus laus zis tshiab xws li 5G thiab cov ntaub ntawv loj, txoj kev loj hlob ntawm holographic zaub yav tom ntej yog qhov tsis xav tsis thoob.Iav-raws li Micro LED tuaj yeem npog daim ntawv thov ntawm cov khoom loj, nruab nrab thiab me me.Kev lag luam loj yuav tsum loj hlob sai los ntawm 2024, thiab nws xav tias yuav tsim kom muaj ib qho kev lag luam nyob rau sab saud thiab nqes dej.
Tom qab xyoo ntawm kev tshawb fawb thiab kev loj hlob, Micro LED cov zaub loj tau ua tiav qhov tseem ceeb hauv kev tsim khoom loj xyoo no, thiab tau dhau los ua lub zog tsav tsheb hauv kev txhim kho cov khoom muaj feem xyuam, khoom siv thiab kev tsim khoom.Qhov sib ntxiv ntawm ntau manufacturers thiab tus nruam txoj kev loj hlob qauv ntawm miniaturization tau prompted lubMicro LED kev lag luamkom tsis tu ncua ua tiav cov thev naus laus zis tshiab, thiab kev lag luam nplai kuj tseem nthuav dav ntxiv.
Ntxiv nrog rau cov lus qhia loj loj, Micro LED muaj cov yam ntxwv zoo heev uas tuaj yeem siv nrog kev hloov pauv thiab nkag mus rau hauv qab.Nws tuaj yeem tshwm sim hauv cov khoom siv tsheb thiab cov khoom siv coj los siv, tsim kom muaj lub sijhawm thov tshiab uas txawv ntawm cov cuab yeej siv tam sim no.Kev nkag ntawm ntau lub tuam txhab thiab kev txhim kho cov qauv ntawm kev txuas ntxiv miniaturization yuav yog tus yuam sij rau kev txo qis ntawm cov nqi nti.
Cov duab yav tom ntej yuav tsum muaj peev xwm tso tes dawb, thiab mloog ntau lub zog ntawm lub vijtsam kom ua tiav kev sib cuam tshuam.Qhov no yuav tsum tau hais tias cov zaub yuav tsum muaj qhov sib txawv siab, siab PPI, siab ci ntsa iab, thiab txawm tias ncua kev muaj tiag.Tam sim no, Micro LED tuaj yeem ua tau raws li cov kev xav tau ntawm kev lag luam zaub yav tom ntej, tab sis cov txheej txheem kev lag luam tseem yuav tsum tau nrawm dua.Feem ntau hais lus, kev lag luam ntawm Micro LED yuav tsum xub paub txog qhov loj ntawm cov chips thiab kev ua kom zoo ntxiv ntawm kev ua haujlwm.Qhov thib ob, kev hloov pauv loj yuav tsum tau ua ke nrog kev kho kom ua tiav cov khoom lag luam loj.Thib peb, nyob rau hauv cov xwm txheej ntawm kev tsav tsheb micro-tam sim no, kev tsim khoom ntawm Micro LED xav tau kev txhim kho ntxiv.Thaum kawg, kev lag luam ecology tseem nyob hauv kev tsim kho, thiab cov nqi kho vajtse yuav tsum tau qis dua.
Kev lag luam yuav tsum xav txog yuav ua li cas txhawm rau txhim kho kev tsim khoom ntawm Micro LED, uas suav nrog kev kho.Muaj kaum tawm lab tus LEDs hauv TV.Yog tias lawv raug xa mus rau lub substrate, txawm tias tus nqi tawm los tuaj yeem ncav cuag 99.99%, tseem muaj ntau qhov chaw uas yuav tsum tau kho thaum kawg, thiab nws yuav siv sij hawm ntev.Kuj tseem muaj qhov teeb meem ntawm qhov ci tsis sib xws ntawm cov zaub.Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm huab hwm coj ceev, yield tus nqi thiab tus nqi, Micro LED tseem tsis muaj qhov zoo dua piv nrog cov kua siv lead ua kua tam sim no.Txawm hais tias kev lag luam tau ua haujlwm ntau hauv kev hloov pauv loj, Micro LED tseem muaj txoj hauv kev mus ntev ua ntej nws tuaj yeem ua tiav ntau lawm.Muaj ob txoj hauv kev tseem ceeb rau kev hloov pauv huab cua, ib qho yog Pick & Chaw, thiab lwm qhov yog laser loj hloov.
Tom qab cov kua siv lead ua kua, Micro LED yog cov neeg sib tw muaj zog ntawm cov cim tshiab ntawm cov khoom siv thev naus laus zis, thiab Micro LED nti yog qhov tseem ceeb txuas.Nws tau nkag siab tias qhov loj ntawm Micro LED tsuas yog ib feem pua ntawm thawj lub ntsiab tseem ceeb LED nti, ncav cuag qhov kev txiav txim ntawm kaum ntawm microns.
Los ntawm LED mus rau Mini LED, tsis muaj qhov sib txawv loj hauv chip technology thiab nti txheej txheem hauv cov ntsiab lus, tab sis cov nti loj hloov pauv.Qhov kev hloov pauv tseem ceeb hauv kev txhim kho ntawm Micro LED yog qhov nti ntu ntu tsis tuaj yeem ua tiav los ntawm thinning thiab scribing sapphire substrate, tab sis GaN nti yuav tsum tau tev tawm ntawm sapphire substrate ncaj qha.Cov cuab yeej siv tam sim no tsuas yog laser nqa-tawm thev naus laus zis, uas nws tus kheej yog cov txheej txheem kev puas tsuaj, uas tsis paub tab hauv Suav teb.Qhov no yog thawj qhov teeb meem uas lub chip ntsib.
Qhov thib ob qhov teeb meem yog qhov dislocation ceev ntawm Micro LED nti, uas muaj kev cuam tshuam loj heev ntawm qhov sib xws ntawm Micro LED nti.Thaum pib, qhov dislocation ceev nyob rau hauv GaN LED epitaxy yog siab li 1010. Txawm hais tias qhov dislocation ceev yog siab, lub luminous efficiency kuj siab.Tom qab gallium nitride LED tau tsim nyob rau hauv Nyiv, tom qab ntau tshaj 30 xyoo ntawm txoj kev loj hlob, cov txheej txheem optimization tau mus txog lub qab nthab, thiab dislocation ceev tau mus txog 5 × 108.Txawm li cas los xij, vim yog qhov siab dislocation ceev ntawm cov cuab yeej LED uas twb muaj lawm, kev txhim kho ntawm Micro LED tuaj yeem txwv txoj kev loj hlob ntawm cov khoom tom ntej.Yog li ntawd, txuas ntxiv cov cuab yeej LED uas twb muaj lawm thiab tsim Micro LED yuav tsum tau daws ob qho teeb meem.Ib qho yog txhawm rau txo qhov tsis sib xws ntawm cov khoom siv gallium nitride, thiab lwm qhov yog txhawm rau nrhiav lub tshuab nqa zoo dua li laser nqa-tawm tshuab.
