Thaum Lub Peb Hlis 14, Kaus Lim Kauslim tau tshaj tawm tias Kaus Lim Kauslim Lub Tsev Haujlwm ntawm Machinery thiab Khoom Siv (KIMM), uas yog lub chaw haujlwm ntawm Ministry of Science thiab ICT, tau ua tiav lub ntiaj teb thawj zaug distortion-dawb, stretchable Micro LED zaub technology (Meta- zaub technology), cov zaub tuaj yeem ncav cuag 25 feem pua tsis muaj qhov cuam tshuam cov duab.
Cov txheej txheem, tsim los ntawm pab pawg tshawb fawb coj los ntawm Jang Bong-kyun, tus kws tshawb fawb laus hauv Department of Nanomechanics ntawm KIMM, tam sim no tau luam tawm hauv phau ntawv xov xwm Advanced Functional Materials.
Nws tau nkag siab tias qhov uas pab pawg tshawb fawb KIMM tau tsim yog ib qho 3-inch Micro LED zaub uas yuav tsis ua rau cov duab tso duab distortion txawm tias nws yog ncab rau hauv ib qho kev taw qhia, uas yog ua tiav los ntawm kev siv metamaterials (Metamaterials) tsim thiab kev tsim technology, cov khoom siv metamaterial no yog cov khoom sib xyaw ua ke nrog cov khoom siv tshwj xeeb uas tsis muaj nyob hauv qhov xwm txheej, thiab tau hais tias muaj kev thov dav dav hauv cov khoom siv hluav taws xob xws li antennas, electromagnetic stealth, thiab metalens.
Raws li cov ntaub ntawv, feem ntau stretchable cov ntaub ntawv nyob rau hauv cov xwm, xws li roj hmab, shrink nyob rau hauv dav thaum stretched longitudinally, ua rau cov duab distortion, thiab qhov no yog tam sim no rooj plaub rau stretchable qhia raws li roj hmab.
Pab pawg tshawb fawb KIMM tau siv cov khoom siv hluav taws xob uas muaj qhov tsis zoo ntawm Poisson qhov cuam tshuam rau cov laug cam. Poisson tus piv yog hais txog qhov sib piv ntawm qhov dav shrinkage thaum cov khoom yog stretched longitudinally. Thaum ib tug neeg kho tshuab metamaterial nrog Poisson tus piv ntawm -1 yog stretched longitudinally, nws nthuav tawm cov nyhuv ntawm stretching transversely ntawm tib tus piv. Yog li ntawd, kev siv Cov Khoom Siv ntawm cov khoom siv no yog cov duab tsis txawv txav.
Cov xov xwm Kauslim tau hais tias qhov kev tsim kho tshiab hloov pauv hloov pauv hloov pauv meta-display yuav tsum tau siv rau cov khoom siv hluav taws xob, xws li xov tooj ntawm tes thiab ntsiav tshuaj computers. Qhov no Micro LED meta-display thev naus laus zis kuj tuaj yeem siv rau tib neeg cov tawv nqaij yam tsis muaj wrinkles, yog li nws yuav tsum tau siv rau hauv cov khoom siv kho mob. , kev zoo nkauj thiab kev kho mob thiab lwm yam kev lag luam tau raug siv.
