MicroLED yog hom lub teeb emitting diode (LED), feem ntau tsawg dua 100μm loj.Qhov ntau thiab tsawg yog tsawg dua 50 μm, thiab qee qhov me me li 3-15 μm.Nyob rau hauv cov nqe lus ntawm scale, MicroLEDs yog hais txog 1/100 qhov loj ntawm cov pa LED thiab txog 1/10 qhov dav ntawm tib neeg cov plaub hau.Hauv MicroLED zaub, txhua pixel yog hais txog tus kheej thiab tsav kom tawm lub teeb yam tsis tas yuav muaj lub teeb rov qab.Lawv yog ua los ntawm cov ntaub ntawv inorganic, uas muab lub neej ntev kev pab cuam.
PPI ntawm MicroLED yog 5,000 thiab qhov ci yog 105nit.PPI ntawm OLED yog 3500, thiab qhov ci ci yog ≤2 x 103nit.Zoo li OLED, qhov zoo ntawm MicroLED yog qhov ci ntsa iab, kev siv hluav taws xob tsawg, kev daws teeb meem ultra-siab thiab xim saturation.Qhov zoo tshaj plaws ntawm MicroLED los ntawm nws qhov loj tshaj plaws, qhov micron-theem suab.Txhua pixel tuaj yeem hais txog kev tswj hwm thiab ib lub ntsiab lus tsav kom tawm lub teeb.Piv nrog rau lwm cov LEDs, MicroLED tam sim no nyob rau hauv cov nqe lus ntawm luminous efficiency thiab luminous zog ceev, thiab tseem muaj chaw rau kev txhim kho.Nws yog qhov zoo rauflexible LED zaub.Cov txiaj ntsig tam sim no yog tias, piv rau MicroLED thiab OLED, kom ua tiav tib lub teeb ci, tsuas yog kwv yees li 10% ntawm thaj tsam txheej tom kawg yog xav tau.Piv nrog OLED, uas tseem yog lub teeb pom kev ntawm tus kheej, qhov ci ci yog 30 npaug siab dua, thiab qhov kev daws teeb meem tuaj yeem ncav cuag 1500PPI, uas yog sib npaug li 5 npaug ntawm 300PPI siv los ntawm Apple Watch.
Txij li thaum MicroLED siv cov khoom siv tsis zoo thiab muaj cov qauv yooj yim, nws yuav luag tsis muaj teeb pom kev zoo.Nws lub neej ua haujlwm ntev heev.Qhov no yog incomparable nrog OLED.Raws li cov khoom siv organic, OLED muaj nws qhov tsis xws luag-lifespan thiab stability, uas yog ib qho nyuaj rau piv nrog QLED thiab MicroLED ntawm inorganic cov ntaub ntawv.Muaj peev xwm hloov mus rau ntau qhov ntau thiab tsawg.MicroLEDs tuaj yeem tso rau ntawm cov substrates sib txawv xws li iav, yas, thiab hlau, ua kom yooj yim, khoov tau.
Muaj ntau chav rau kev txo nqi.Tam sim no, lub tshuab micro-projection yuav tsum tau siv lub teeb pom kev sab nraud, uas ua rau nws nyuaj rau kev txo qhov loj ntawm module, thiab tus nqi kuj tseem siab.Nyob rau hauv sib piv, tus kheej-illuminating MicroLED microdisplay tsis xav tau ib tug lwm lub teeb qhov chaw, thiab lub optical system yog yooj yim dua.Yog li ntawd, nws muaj qhov zoo hauv miniaturization ntawm module ntim thiab txo nqi.
Nyob rau hauv luv luv, lub lag luam Micro-LED yog tsom rau ultra-me me qhia.Nyob rau hauv nruab nrab thiab ntev, daim ntawv thov teb ntawm Micro-LED yog dav heev.Thoob plaws hauv cov khoom siv coj los siv, cov ntxaij vab tshaus sab hauv tsev loj, lub taub hau-mounted zaub (HUDs), taillights, wireless optical kev sib txuas lus Li-Fi, AR / VR, projectors thiab lwm yam.
Lub hauv paus ntsiab lus ntawm MicroLED yog kom nyias, me me thiab array ntawm LED qauv tsim.Nws loj tsuas yog li 1 ~ 10μm.Tom qab ntawd, MicroLEDs raug xa mus rau hauv cov khoom siv hluav taws xob hauv cov khoom siv, uas tuaj yeem ua kom nruj lossis hloov tau yooj yim pob tshab lossis opaque substrates.Pob tshab LED zaubkuj yog qhov zoo.Tom qab ntawd, cov txheej txheem tiv thaiv thiab cov khoom siv hluav taws xob sab saud yog ua tiav los ntawm cov txheej txheem ntawm lub cev deposition, thiab tom qab ntawd lub substrate sab saud tuaj yeem ntim tau los ua kom tiav MicroLED zaub nrog cov qauv yooj yim.
Txhawm rau ua kom pom, qhov saum npoo ntawm cov nti yuav tsum tau ua rau hauv cov qauv array zoo li cov duab LED, thiab txhua qhov pixel yuav tsum tau nyob thiab tswj tau thiab tus kheej tsav kom pom.Yog tias nws tau tsav los ntawm kev sib txuas ntawm cov hlau oxide semiconductor Circuit Court, nws yog ib qho chaw hais txog kev tsav tsheb, thiab ntim tshuab tuaj yeem dhau ntawm MicroLED array nti thiab CMOS.
Tom qab muab tshuaj txhuam tiav, MicroLED tuaj yeem txhim kho qhov ci ntsa iab thiab qhov sib txawv los ntawm kev sib xyaw ntawm microlens array.MicroLED array txuas nrog rau qhov zoo thiab tsis zoo electrodes ntawm txhua MicroLED los ntawm vertically staggered zoo thiab tsis zoo daim phiaj electrodes, thiab cov electrodes yog energized nyob rau hauv sequence, thiab cov MicroLEDs yog lit los ntawm scanning los tso saib dluab.
Raws li ib qho kev sib txuas hauv kev lag luam, Micro LED muaj cov txheej txheem nyuaj uas lwm cov kev lag luam hluav taws xob tsis tshua siv-kev hloov pauv loj.Kev hloov pauv loj yog suav tias yog qhov tseem ceeb cuam tshuam rau cov txiaj ntsig tau thiab muaj peev xwm tso tawm, thiab nws tseem yog thaj chaw uas cov tuam txhab loj tsom mus rau kev daws teeb meem nyuaj.Tam sim no, muaj cov lus qhia sib txawv ntawm txoj hauv kev, uas yog laser hloov chaw, kev sib koom ua ke ntawm tus kheej thiab hloov tshuab.
Dab tsi ntawm technology yog "hloov pauv loj"?Txhawm rau muab nws yooj yim, ntawm TFT Circuit Court substrate qhov loj ntawm tus ntiv tes, raws li qhov tsim nyog tshwj xeeb ntawm optics thiab hluav taws xob, peb mus rau tsib puas lossis ntau dua liab, ntsuab thiab xiav LED micro-chips yog sib npaug.
Cov txheej txheem tso cai tsis ua haujlwm yog 1 ntawm 100,000.Tsuas yog cov khoom lag luam uas ua tiav cov txheej txheem no tuaj yeem siv tiag tiag rau cov khoom lag luam xws li Apple Watch 3. Nto mount thev naus laus zis tam sim no tau ua tiav cov khoom siv thev naus laus zis ntau lawm hauv MINI LED, tab sis nws xav tau kev txheeb xyuas qhov tseeb hauv MicroLED ntau lawm.
Txawm tiasMicroLED zaubyog kim heev piv rau cov pa LCD thiab OLED vaj huam sib luag, lawv qhov zoo nyob rau hauv brightness thiab lub zog efficiency ua rau lawv ib tug txaus nyiam lwm txoj hauv ultra-me me thiab loj heev daim ntaub ntawv.Sij hawm dhau mus, cov txheej txheem tsim khoom MicroLED yuav tso cai rau cov neeg muag khoom kom txo cov nqi tsim khoom.Thaum cov txheej txheem ncav cuag kev loj hlob, MicroLED muag yuav pib nce.Txhawm rau ua piv txwv li no, los ntawm 2026, tus nqi tsim khoom ntawm 1.5-nti microLED cov lus qhia rau smartwatches xav tias yuav poob mus rau ib feem kaum ntawm tus nqi tam sim no.Tib lub sijhawm, tus nqi tsim khoom ntawm 75-nti TV zaub yuav poob mus rau ib feem tsib ntawm nws cov nqi tam sim no nyob rau tib lub sijhawm.
Hauv ob xyoos dhau los, Mini Led kev lag luam yuav hloov pauv cov khoom siv thev naus laus zis tshiab.Xyoo 2021, kev lag luam khoom siv hluav taws xob xws li cov khoom siv tsheb, cov khoom siv hauv tsev, cov rooj sib tham, kev ruaj ntseg zaub thiab lwm yam kev lag luam hluav taws xob yuav ua rau muaj kev tawm tsam dav dav thiab txuas ntxiv mus kom txog thaum Micro LED cov khoom siv ntau lawm.
