Qhov kev cia siab ntau ntawm cov khoom siv tshiab, Micro LED, tau siv los ntawm qhov loj mus rau qhov me me, thiab los ntawm sab hauv mus rau sab nraum zoov.Ob txoj kev txhim kho loj no tseem tab tom nce mus ntxiv.Txog tam sim no, ntau lub tsev tshawb fawb tseem muaj kev cia siab txog kev loj hlob ntawm kev kwv yees ntawm Micro LED kev lag luam tus nqi.Nws zoo dua rausaj zawg zog coj screen.Txawm li cas los xij, qhov teeb meem tus nqi uas tau daig ntawm qhov tseem ceeb ntawm Micro LED kev lag luam tseem nyob rau theem ntawm kev sib tham thiab khiav-hauv nruab nrab ntawm cov dej ntws thiab cov dej ntws.Nyob rau hauv luv luv, tam sim no tsis muaj kev daws teeb meem ceev thiab zoo rau Micro LEDs uas tau resonated dav hauv kev lag luam.
Pom tias OLED tab tom txhim kho cov khoom siv hloov pauv ntawm qhov nrawm nrawm, nws nkag mus rau ntau tus neeg siv khoom siv hluav taws xob thiab kev lag luam tsheb.Tom qab TFT LCD nrog MiniLED backlight tau raug hem, yog tias lub sij hawm taw tes ntawm kev tsim khoom loj ntawm Micro LED ntawm tus nqi tsim nyog raug ncua, tej zaum yuav muaj ntau qhov sib txawv.Nrog rau txoj kev loj hlob ntawm Micro LED kev lag luam saw hauv Taiwan, Chichuang Technology yog tus pioneer ntawm kev daws teeb meem.
AUO thiab nws lub tuam txhab koom nrog Fucai xav tias yuav muaj lub sijhawm los ua tus thawj coj hauv kev ua raws li cov peev txheej ntau lawm.Micro LED tau qw nrov nrov rau ntau xyoo, thiab thaum kawg nws tau nkag mus rau ntau lawm xyoo no.Nws cia siab tias yuav muaj kev poob qis hauv cov nqi thiab cov nqi rau xyoo no, thiab tseem yuav poob rau ob peb xyoos tom ntej no.Qhov no los txawm tias poob qis hauv kev thov rau cov neeg siv khoom siv hluav taws xob thiab kev siv nyiaj txiag kev lag luam thaum lub ntiaj teb kev nce nyiaj txiag thiab cov paj laum nce siab los ntawm cov tsev txhab nyiaj hauv nruab nrab.
Thawj zaug yuav yog qhov miniaturization ntawm Micro LED chips, uas tej zaum yuav raug txo ntxiv rau yav tom ntej.Qhov no txhais tau hais tias tib lub epitaxy tuaj yeem tau txais ntau dua Micro LED chips, thiab tus nqi ntawm Micro LED chips yuav txo qis.Tsis tas li ntawd, ntau thiab ntau dua chip manufacturers yog
nqis peev hauv MicroLED kev lag luam saw, uas tseem pab txhawb kev txhim kho cov txiaj ntsig thiab txo tus nqi thiab tus nqi.Tam sim no, nws tau kwv yees tias Micro LED chips muaj lub sijhawm los txo qis ntawm tus nqi ntawm 30% -40% ib xyoos, uas yog qhov tsim nyog rau kev ua kom nrawm dua. txheej txheem ntawm kev lag luam.
Tsis tas li ntawd, los ntawm kev txhim kho cov cuab yeej siv tshuab thiab cov txheej txheem, mus rau qhov rov qab-kawg hlau txuas thiab kev sib koom ua ke, kuj tseem muaj chaw rau kev txhim kho kev ua haujlwm ntawm Micro LED thiab txo tus nqi.Micro LEDs tam sim no tsom ntau lub hom phiaj siv.Xws li cov khoom siv coj los siv (tshwj xeeb tshaj yog cov khoom tshiab xws li Metaverse AR iav), TVs loj lossis cov khoom siv high-end, automotive displays, thiab lwm yam. Feem ntau, Micro LEDs tuaj yeem muab tso rau ntawm cov substrates hloov tau, uas tuaj yeem tsim ntau cov duab tshiab thiab kev siv scenarios.Ntawm lawv, cov khoom siv hnav tau cia siab tias yuav muaj cov khoom tshiab ntxiv siv Micro LED zaub hauv 2023.P1.5 LED video phab ntsa.Tseem yuav muaj ntau lub npe tshaj tawm txog cov khoom lag luam.Kev taw qhia ntawm cov khoom siv tsheb yuav siv sijhawm ntev, tab sis HUD head-up displays muaj lub sijhawm los ua tus thawj coj ntawm Micro LED hauv kev siv tsheb.
Nws tsim nyog hais tias Micro LED epitaxy thev naus laus zis.Los ntawm lub zog muaj zog physics, cov yeeb yaj kiab zoo GaN nyias tuaj yeem loj hlob ntawm qhov kub thiab txias, tso tseg tag nrho cov txheej txheem hloov pauv loj.Tus nqi tsuas yog ib feem kaum ntawm cov khoom siv micro-LED uas twb muaj lawm.Nws muaj peev xwm rau kev tsim khoom loj, thiab cov thev naus laus zis cuam tshuam tau txais patents hauv Taiwan thiab Tebchaws Meskas.
Kev hloov pauv loj yog cov kauj ruam tseem ceeb tshaj plaws nyob rau niaj hnub no Micro LED zaub thiab tau nyob hauv kev txhim kho rau ze li ntawm kaum xyoo.Tab sis pab neeg ntseeg tias kev hloov pauv loj yog qhov tsis ncaj ncees lawm.Feem ntau yog vim tam sim no LED nti whisker flip-chip txheej txheem thiab cov txheej txheem tsis muaj zog.Cov khoom siv lub teeb xiav-ntsuab yog gallium nitride, thiab cov khoom siv lub teeb liab yog gallium arsenide.Kev tsav tsheb voltage ntawm ob cov khoom sib txawv, thiab kev tsav tsheb yuav ua rau muaj kev nyuaj.Tshwj xeeb tshaj yog nyob rau hauv cov nqe lus ntawm tus nqi, qhov teeb meem ntawm tuag pixel kho tsis yooj yim rau kov yeej, yog li nws yog ib qho nyuaj rau loj tsim.
Los ntawm lub zog physics, yav dhau los qhov kub thiab txias txwv ntawm ntau tshaj 1,000 degrees tau tawg.Cov yeeb yaj kiab zoo gallium nitride tuaj yeem loj hlob ntawm qhov kub thiab txias, thiab qhov kub tuaj yeem tswj tau ntawm thaj tsam 500 txog 700 degrees.Zoo raupob tshab coj zaub.Cov vaj huam sib luag loj muaj los ntawm 2 ntiv mus rau 12 ntiv tes.Nws tuaj yeem ntsuas nrog cov txheej txheem cov cuab yeej thiab ua ke nrog cov ntaub ntawv loj tsom xam kom pom qhov zoo tshaj plaws epitaxial hom.Nws tus kheej tsim epitaxial phaj, ua ke nrog nanomaterial technology, tuaj yeem ua tiav cov xim micro-LED cov nyhuv tag nrho.Tus nqi ntawm ib lub vaj huam sib luag tsuas yog ib feem kaum ntawm qhov uas twb muaj lawm, thiab nws muaj peev xwm loj heev rau kev tsim khoom loj.
