Nyob rau hauv xyoo tas los no, Micro LED tau raug suav hais tias yog lub cim tshiab ntawm cov khoom siv vaj huam sib luag tom qab LCD thiab OLED vim nws lub zog siv tsawg, cov lus teb ceev ceev, lub neej ntev thiab kev ua haujlwm siab. Lub npe lus Askiv tag nrho ntawm Micro LED yog Micro Light Emitting Diode, uas yog hu ua Micro Light Emitting Diode hauv Suav. Nws tseem tuaj yeem sau ua μLED. Nws thins, miniaturizes thiab matrixes tsoos LEDs, txo cov pixel nrug ntawm millimeters mus rau micrometers. , Thiab kev sib xyaw ua ke ntawm cov khoom siv tus kheej luminous zaub ntawm lub nti. Qhov loj tshaj qhov sib txawv ntawm cov pa LEDs yog qhov loj. Qhov loj yog sib npaug rau 1/10 ntawm tib neeg cov plaub hau, thiab lub ntim nce mus txog 1 feem pua ntawm lub ntsiab LED loj. Txawm li cas los xij, lub pixel loj yog tam sim no tseem Tsis muaj lub ntsiab txhais.
Micro LED's micron-theem pixel suab tuaj yeem ua rau nws npog ntau yam kev thov los ntawm cov duab me thiab nruab nrab mus rau qhov nruab nrab thiab loj loj. Piv nrog rau cov tsoos me me-pitch LEDs, vim qhov txo qhov loj me, cov duab daws teeb meem thiab cov duab zoo tau zoo tuaj. Kev tsim kho qhov muag tuaj yeem ua rau pom lub kaum sab xis dav dua, qhov sib piv siab dua, thiab cov duab zoo dua. Nws yog qhov tsim nyog rau kev muaj tiag virtual, me me projectors, thiab micro Ntau yam kev tshwm sim xws li saib, pom lub teeb sib txuas lus, kev tshawb fawb kho mob, thiab lwm yam. embedded sensing functions, thiab nws tseem tuaj yeem ua ke nrog cov substrates saj zawg zog kom ua tiav cov duab hloov tau yooj yim, uas tuaj yeem siv rau cov khoom siv coj los siv / cog thiab cov khoom siv tsheb. Tsis tas li ntawd, Micro LED muaj cov ntsiab lus siab, siab ci, zoo sib xws, thiab siab teb ceev. Nws yog qhov tsim nyog rau VR, AR thiab lwm yam khoom siv hnav uas muaj cov kev xav tau siab rau cov lus teb ceev (siab ci ntsa iab thiab txuag hluav taws xob tsim nyog rau kev hnav sab nraum zoov) daim ntawv thov.
Lub tswv yim ntawm Micro LED zaub tau pib hauv 2000 txog 2012. Tom qab Sony tau nthuav tawm thawj Crystal-LED microLED TV, Micro LED zaub tau tshwm sim hauv ntiaj teb kev lag luam. Cov koom haum tshawb fawb sib txawv thiab cov tuam txhab pib tsom mus rau miniaturization thiab xim puv. Bottleneck technologies xws li wafer hloov lwm lub tsev, thiab lwm yam raws li qhov loj ntawm lub vaj huam sib luag zaub rau cov kev siv sib txawv, kev npaj cov zaub tuaj yeem muab faib ua monolithic manufacturing technology thiab loj hloov tshuab. Monolithic manufacturing technology yog hais txog kev tsim khoom ncaj qha ntawm Micro LED ntawm Si, GaN lossis Sapphire substrates. Rau cov kev daws teeb meem siab, LED yog sib koom ua ke rau lub davhlau ya nyob twg tso saib substrate, thiab thaum kawg lub substrate yog tev tawm los ntawm lub cev lossis tshuaj lom neeg. Txoj kev no zam cov txheej txheem hloov pauv loj heev, tab sis nws kuj tseem txwv rau kev tsim cov duab me me, xws li cov duab nyob ze, smart watches thiab lwm yam micro zaub, uas txwv tsis pub siv cov xwm txheej ntawm Micro LED; Tsis tas li ntawd, txhua txoj kev tuaj yeem tsuas yog nyob rau ntawm substrate Ib qho xim ntawm lub teeb hlaws nti tau loj hlob, yog li qhov no ib leeg-chip manufacturing technology tsis tuaj yeem daws RGB puv xim. Lub quantum dot puv-xim zaub tau npaj nyob rau xyoo tas los no siv lub teeb tawm los ntawm ib qho ultraviolet Micro LED kom zoo siab rau cov xim liab, ntsuab thiab xiav luminescent nruab nrab uas npog los ntawm txheej sab saud kom ua tiav cov xim. Qhov no colorization lwm technology tej zaum yuav sau rau yav tom ntej. Cov kev txwv ntawm monolithic manufacturing nyob rau hauv cov nqe lus ntawm tag nrho cov xim. Lwm cov tshuab tsim khoom yog kev hloov pauv loj. LED nti yog loj hlob ntawm qhov chaw substrate, thiab tom qab ntawd cov LED tau sib cais los ntawm qhov chaw substrate thiab cov nti tau nrawm, raug thiab ntseeg tau xa mus rau cov khoom siv hluav taws xob los ntawm qee lub zog. Rau ntau yam kev siv zaub xws li xov tooj ntawm tes, vaj huam sib luag tiaj tus thiab TVs, kev sib cais los ntawm cov substrate tom qab kev tsim khoom ntawm substrate tiav, inevitably yuav tsum muaj kev hloov loj heev los hloov Micro LED nti mus rau qhov loj dua thiab nrog cov logic. circuits. Sib sau ua ke ntawm lub substrate kom tau raws li qhov xav tau ntawm daim ntawv thov. Tsis tas li ntawd, kev siv cov khoom siv optoelectronic hloov tau yooj yim thiab stretchable rau hnav thiab bioelectronic daim ntaub ntawv tsis ntev los no tau txais kev tshawb fawb dav dav thiab muaj koob meej. Cov ntawv thov no xav tau kev hloov pauv ntawm LEDs mus rau qhov hloov pauv hloov pauv thiab tseem xav tau kev hloov pauv loj kom ua tiav. Txawm li cas los xij, vim qhov loj me me thiab loj loj ntawm wafers hloov txhua lub sijhawm, qhov tseeb thiab qhov xav tau ceev ntawm cov txheej txheem hloov chaw yog siab heev, uas tau dhau los ua cov thev naus laus zis tseem ceeb txwv qhov loj ntawm Micro LEDs.
