Tom ntej no-tiam zaub technology Micro LED tau dhau los ua qhov tseem ceeb tshaj plaws ntawm lub xyoo no Kov Taiwan Smart Display Exhibition.Nrog rau kev qhib thawj xyoo ntawm Micro LED xyoo tas los, cov tuam txhab lag luam loj tau pom ntau qhov kev simulation thiab cov ntawv thov rau pem hauv ntej xyoo no, thiab 2022 yuav tsis muaj qhov tsis ntseeg yog xyoo tseem ceeb tom qab pib.Nrog rau kev ua tiav ntawm kev siv thev naus laus zis, Micro LED cov tuam txhab tau maj mam hla ob lub roob ntawm "nqi" thiab "yield", thiab tab tom ntsib lub "qab ntug tshiab" hauv lub qhov muag ntawm Micro LED.
Cov txheej txheem Micro LED feem ntau yog muab faib ua cov chips loj hlob, chip manufacturing, nyias zaj duab xis txheej txheem, loj hloov mus, tshuaj xyuas thiab kho.Vim qhov kev tshem tawm ntawm LED pob thiab substrate, tawm hauv epitaxial zaj duab xis, Micro LED nti yog sib dua, thinner thiab luv dua, muab ntau yam duab pixel loj.Tam sim no, Micro LED kuj tau txais txiaj ntsig zoo ntawmLED zaub, nrog kev daws teeb meem siab, siab ci, lub neej ntev, dav xim gamut, nws tus kheej-luminous yam ntxwv, qis zog noj, thiab zoo ib puag ncig stability, haum rau yav tom ntej ntse zaub daim ntaub ntawv, xws li tsheb, AR tsom iav, wearable devices, thiab lwm yam.
Piv nrog rau cov txheej txheem tsim LED ib txwm muaj, cov kauj ruam ntawm Lei nti kev loj hlob, Micro LED nti tsim, thiab nyias zaj duab xis tsim cov txheej txheem tuaj yeem siv rauP1.56 hloov tau coj zaubkev tsim khoom tsuas yog los ntawm kev hloov kho cov khoom siv, tab sis nws yog qhov nyuaj dua rau kev hloov pauv, kuaj xyuas thiab kho cov khoom loj.Ntawm lawv, kev hloov pauv loj, kev tshuaj xyuas thiab kho, thiab kev ua haujlwm zoo ntawm liab Micro LED yog cov tsis muaj zog hauv cov thev naus laus zis tam sim no, thiab lawv kuj yog tus yuam sij rau kev cuam tshuam cov nqi thiab cov txiaj ntsig.Thaum cov teeb meem no tau tawg thiab tus nqi raug txo, muaj lub sijhawm rau kev tsim khoom loj.kauj ruam tom ntej.
Ib qho teeb meem rau "New Horizons": Kev Hloov Loj
Txij li lub thickness ntawm lub epitaxial substrate yog loj dua qhov luaj li cas ntawm nti, lub Micro LED yuav tsum loj-hloov, nti yog tev tawm, muab tso rau ntawm ib ntus cia substrate, thiab ces lubMicro LEDyog pauv mus rau lub rooj tsav xwm zaum kawg lossis TFT version.Cov thev naus laus zis loj loj hauv theem no suav nrog kev sib sau ua kua, laser hloov, xaiv thiab tso thev naus laus zis (Stamp Pick & Place), thiab lwm yam.
Pick-and-place technology siv MEMS array technology rau chip pick-and-place technology, tab sis tsoos LED pick-and-place technology muaj tus nqi siab vim nws qeeb de-thiab-qhov chaw;Raws li rau laser hloov, Micro LEDs tau sai thiab loj heev pauv los ntawm thawj substrate los ntawm ib tug laser beam Micro LED rau lub hom phiaj substrate.Yang Fubao, tus kws tshuaj ntsuam xyuas ntawm TrendForce, tau taw qhia tias cov khoom siv niaj hnub tau nyuaj rau kev tsim khoom loj vim nws qeeb qeeb thiab tus nqi siab yav dhau los.Yog li ntawd, xyoo no, thev naus laus zis tau maj mam hloov los ntawm ib txwm khaws mus rau high-precision thiab ceev laser tshuab.hloov mus los pab txo cov nqi.Raws li rau cov kua sib dhos tshuab, lub interface ntawm molten solder capillary yog siv, thiab cov kua dej ncua kev kawm ntawv yuav siv tau raws li ib tug nruab nrab thaum lub sij hawm sib dhos rau mechanically thiab hluav taws xob txuas cov electrodes, thiab sai sai ntes thiab kho cov Micro LEDs rau lub solder pob qij txha. .Kev sib dhos ceev yog ua tau.Tsis ntev los no, Huawei tau nquag siv Micro LED thev naus laus zis.Los ntawm qhov kev xav ntawm cov ntaub ntawv patent, nws yog feem ntau yuav siv cov kua sib dhos tshuab.
"Tshiab Horizons" Obstacle No. 2: Kev Tshawb Nrhiav thiab Kho
Txawm hais tias kev hloov pauv huab hwm coj ib txwm yog tus yuam sij rau kev tsim khoom loj, qhov tseem ceeb ntawm kev tshuaj xyuas tom ntej thiab kho ntawm Micro LED chips tsis yog qhov tseem ceeb tshaj li kev hloov pauv loj.Tam sim no, ob txoj kev siv ntau tshaj plaws hauv kev lag luam yog photoluminescence (PL) thiab electroluminescence (EL).Tus yam ntxwv ntawm PL yog tias nws tuaj yeem kuaj tau yam tsis muaj kev tiv tauj lossis ua rau cov nti LED puas tsuaj, tab sis cov txiaj ntsig kev sim tsis zoo li ntawm EL;ntawm qhov tsis sib xws, EL tuaj yeem pom ntau qhov tsis xws luag los ntawm kev sim LED nti los ntawm kev siv hluav taws xob, tab sis nws yuav ua rau nti puas vim kev sib cuag.
Tsis tas li ntawd, Micro LED nti yog me me dhau los ua kom haum rau cov khoom siv tshuaj ntsuam.Txawm hais tias siv EL lossis PL xeem, tej zaum yuav muaj qhov teeb meem ntawm kev tshawb pom tsis zoo, uas yog ib feem uas yuav tsum tau kov yeej.Raws li kev kho ib feem, Micro LED manufacturers siv ultraviolet irradiation kho tshuab, laser melting kho tshuab, xaiv pick-up kho tshuab, xaiv laser kho tshuab thiab backup circuit tsim kev daws teeb meem.
Qhov thib peb cuam tshuam rau "New Horizons": Liab Micro LED Chips
Thaum kawg, muaj xim ntawm cov zaub nws tus kheej.Rau Micro LEDs, piv rau xiav thiab ntsuab, liab yog xim nyuaj tshaj plaws los tso saib, thiab tus nqi kuj tseem siab.Nitride semiconductors tam sim no siv hauv kev lag luam los tsim cov xiav thiab ntsuab Micro LEDs.Liab Micro LEDs yuav tsum tau tov nrog ntau yam khoom siv los yog tsim nrog phosphide semiconductors.
Txawm li cas los xij, qhov teeb meem xim tsis sib xws yuav tshwm sim thaum lub sijhawm txheej txheem epitaxial.Kev sib xyaw ua ke ntawm cov khoom sib txawv ntawm cov khoom siv semiconductor yuav ua rau muaj kev nyuaj siab ntau lawm thiab tsim cov nqi ntawm cov xim tag nrho Micro LEDs.Cov txheej txheem ntawm kev txiav cov chips kuj tuaj yeem ua rau tsis zoo luminous efficiency, tsis hais txog qhov loj me me., qhov ua tau zoo ntawm phosphide Micro LED chips yuav txo qis.Tsis tas li ntawd, cov khoom siv sib xyaw ua ke yuav tsum muaj nyob rau hauv cov txheej txheem semiconductor, yog li nws yog qhov nyuaj, siv sijhawm ntev, kim, thiab cov txiaj ntsig tsis yooj yim los txhim kho.
Yog li ntawd, qee cov tuam ntxhab tau txhim kho los ntawm cov khoom siv nws tus kheej.Piv txwv li, Porotech, lub tuam txhab Micro LED, tau tshaj tawm lub ntiaj teb thawj indium gallium nitride (InGaN)-raws li lub teeb liab Micro LED zaub, uas txhais tau hais tias tag nrho peb hom kev qhia siv InGaN ua cov khoom siv, uas tsis txwv rau ib qho twg. substrate.Tsis tas li ntawd, JBD, lub chaw tsim khoom loj Micro LED, tau cog lus rau AlGaInP-raws li liab Micro LED thev naus laus zis yav dhau los, thiab tsis ntev los no tshaj tawm tias nws tau mus txog 500,000 nits ntawm ultra-high brightness liab Micro LED ntau lawm.
Txawm hais tias peb tau siv thawj xyoo ntawm Micro LED, ntau yam teeb meem tseem xav tau lub sijhawm los daws kom qeeb.Tam sim no, peb tau pom qhov pib ntawm daim ntawv thov.Nws ntseeg tau tias tom qab lub fwjchim luj kawg nkaus xws li kev hloov pauv loj, kev tshuaj xyuas thiab kev saib xyuas, thiab kev ua haujlwm luminous tau kov yeej ib qho los ntawm ib qho, Micro LED yuav tsum tau ua tiav.Kev lag luam, yav tom ntej, cov ntawv thov coj los ntawm Micro LED tuaj yeem pom hauv cov ntxaij vab tshaus tsheb, cov ntxaij vab tshaus loj, AR / VR cov cuab yeej,high-resolution coj zaubwearable khoom, thiab lwm yam.
