Nrog kev txhim kho txuas ntxiv ntawm MicroLED zaub, ntau txoj kev tawg tau ua hauv tshuab.Tsis ntev los no, tau muaj kev txhim kho tshiab nyob rau hauv Micro LED cov lus, thiab tau muaj ntau yam kev hloov tshiab hauv ntiaj teb.
Yonsei University txhim kho high-resolution tri-xim Micro LED zaub technology
Nws tau tshaj tawm tias pab pawg ntawm xibfwb Jong-hyun Ahn ntawm Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob thiab Hluav Taws Xob ntawm Yonsei University siv MoS2 semiconductors thiab quantum dots kom ua tiav high-resolution tri-xim Micro LED zaub technology.The technology, luam tawm nyob rau hauv "Nature Nanotechnology. ", thiab yog lub ntiaj teb thawj zaug los tsim cov thev naus laus zis sib xyaw siv ob-seem semiconductors thiab quantum dots, yuav tsum tau siv rau hauv kev txhim kho cov kev ua tau zoo tom ntej (AR) thiab virtual reality (VR) cov lus qhia.Nws yog ib txoj xov zoo rauLED kev lag luam.
Txhawm rau tsim Micro LED zaub, cov txheej txheem nyuaj ntawm tus kheej hloov pauv peb-xim Micro LED chips mus rau lub rooj tsav xwm rov qab yuav tsum tau ua.Thaum txoj kev tsim khoom no tsim nyog rau kev tsim cov duab loj nrog cov kev daws teeb meem tsawg, nws tsis tuaj yeem ua tau raws li qhov xav tau ntawm lwm tiam augmented reality (AR) thiab virtual reality (VR) cov lus qhia uas xav tau kev daws teeb meem siab thiab kev ua haujlwm siab.
Txhawm rau kov yeej cov kev txwv ntawm kev tsim Micro LED zaub, pab pawg tshawb fawb tau tsim ob sab semiconductor molybdenum disulfide (MoS2) ncaj qha rau ntawm gallium nitride (GaN) wafer rau xiav LEDs, thiab tom qab ntawd sib xyaw cov khoom siv hluav taws xob los tsim ib tus neeg semiconductor circuits, ntse paub lub ntiaj teb thawj 500 PPI (tus naj npawb ntawm Micro LED lub teeb qhov chaw ib nti), siab daws teeb meem Micro LED zaub yam tsis muaj kev hloov pauv.Tsis tas li ntawd, pab pawg tshawb fawb kuj tau tsim cov txheej txheem kom ua tiav peb cov xim thawj zaug los ntawm kev luam ntawv quantum dots ntawm xiav GaN Micro LEDs, uas tuaj yeem txhim kho cov txheej txheem ntawm cov zaub thiab txo cov nqi tsim khoom.Tsis tas li ntawd, thev naus laus zis tsim los ntawm pab pawg tshawb fawb tsis tuaj yeem ua kom yooj yim rau kev tsim cov txheej txheem ntawm MicroLED qhia cov khoom, tab sis kuj ua tiav kev daws teeb meem siab.
Kyung Hee University txhim kho ultra-dense optics array rau AR li
Tsis ntev los no, pab pawg tshawb fawb coj los ntawm xibfwb Lee Seung-hyun ntawm Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob Hluav Taws Xob ntawm Kyung Hee University tau siv ultra-highly integrated micro light-emitting diodes (tom qab no hu ua Micro LEDs) los tsim kho qhov muag khoom arrays nrog pixel loj ntawm plua plav. particles thiab quantum dots thiab xim zoo heev.Kho dua tshiab.Arrays ntawm cov ntsiab lus kho qhov muag yuav tsum tau siv los ua qhov project augmented reality dluab rau ntawm qhov muag.Fusion yog qhov nyuaj vim qhov sib txawv ntawm kev tsim cov khoom siv hluav taws xob thiab Micro LEDs.Feem ntau, cov hluav taws xob hluav taws xob yog tsim los ntawm silicon substrates, thaum Micro LEDs yog tsim los ntawm gallium nitride substrates.Yuav kom daws tau qhov teeb meem no, Xib Fwb Li cov pab pawg tshawb fawb tau tsim cov txheej txheem uas tuaj yeem hloov cov txheej nyias nyias ntawm gallium nitride, txog ib feem kaum ntawm cov plaub hau tuab ntawm tib neeg cov plaub hau, mus rau hauv silicon substrate.
Raws li cov thev naus laus zis no, pab pawg tshawb fawb tau ua tiav lub ntiaj teb qhov me me me me (5μm) LED pixel los ntawm kev siv lub tshuab hluav taws xob silicon nkaus xwb thiab tsis muaj cov txheej txheem dav dav."Cov txheej txheem hloov pauv tau cuam tshuam zoo heev los ntawm kev nthuav dav thermal, yog li peb tau tsom mus rau kev ua cov txheej txheem nyias nyias ntawm qhov kub thiab txias," piav qhia cov tub ntxhais kawm hluav taws xob engineering Shin Yoo-seop.Nyob rau tib lub sijhawm, pab pawg tshawb fawb tau siv quantum dot thev naus laus zis los txhim kho cov xim luam tawm, ntxiv qhov kev xav ntawm qhov tseeb rau AR.Quantum dots tau nyiam ntau yam xws li cov khoom siv hluav taws xob tom ntej vim lawv cov xim purity siab thiab photostability piv rau cov khoom siv teeb pom kev zoo vim tias lawv tuaj yeem tsim los ntawm kev tsim qhov sib txawv ntawm lub teeb wavelengths rau txhua qhov me me yam tsis hloov hom.cov ntaub ntawv ntawm ntau yam xim.Txawm li cas los xij, quantum dots tau raug rau ntau cov kuab tshuaj siv hauv kev ua cov khoom siv hluav taws xob.
Txhawm rau daws qhov teeb meem no, pab pawg tshawb fawb tau tsim "txoj kev hloov pauv hloov pauv siab" uas tuaj yeem xaiv cov qauv raws li qhov siv zog ntawm qhov chaw.Lawv tau ua tiav hauv kev siv quantum dot technology kom ua tiav RGB xim yam tsis muaj kuab lom.Qhov tsim kho qhov muag pixels yog me me txawm tias thaum saib los ntawm lub tshuab tsom iav, ua rau lawv haum rau cov khoom siv me me xws li wearables.Tsis tas li ntawd, cov khoom siv kho qhov muag pixels tuaj yeem pom meejcoj qhov projectaugmented kev muaj tiag dluab los ntawm displaying ib tug siab xim gamut.
