Raws li kev tshaj tawm xov xwm txawv teb chaws, Nitride Semiconductors, Japanese UV LED chaw tsim khoom, tshaj tawm tias nws tau txais daim ntawv pov thawj rau Micro UV LED cov tshuab ua haujlwm siab hauv tebchaws United Kingdom, Lub teb chaws Yelemees thiab Fabkis thaum lub Cuaj Hlis 8, 2021, nrog tus lej patent 3644379; lwm qhov tau txais hauv Tebchaws Meskas thaum Lub Kaum Hli 5, 2021. Tib patent, tus lej patent yog 11,139,342. Cov thev naus laus zis tshiab uas tau txais los ntawm Nitride lub sijhawm no yuav pab ua kom muaj xim liab, ntsuab thiab xiav phosphors los npaj cov xim puv xim.
Nrog kev pab los ntawm superlattice qauv thiab qauv sapphire substrate kom txo cov nti loj rau 50 microns los yog tsawg dua, qhov tshiab patented technology no yuav txhim kho lub luminous efficiency ntawm 385-400nm Micro LED chips. Lub luminous efficiency ntawm lwm cov xim LEDs yuav raug txo vim txo qhov luaj li cas, tab sis qhov tshiab patented technology ntawm Nitride tuaj yeem txo qis hauv kev ua haujlwm.
Feem ntau, nws yog ib qho nyuaj thiab siv sij hawm siv rau daim ntawv cog lus LED chips nrog qhov loj ntawm 20-30 microns ntawm TFT zaub vaj huam sib luag. Nitride tau hais tias cov chips liab, xiav, thiab ntsuab LED sib sau ua ke rau hauv UV LED, uas yooj yim rau kev sib txuas ntawm cov chips thiab tam sim no thiab voltage tswj. Tsis tas li ntawd, Micro UV LEDs tuaj yeem ua rau RGB phosphors kom ua tiav cov xim puv xim.
Txawm hais tias muaj kev xav tias qhov ua tau zoo ntawm UV LEDs tsawg, Nitride ntseeg tias qhov kev siv tshuab ua haujlwm siab no yuav tsum ua kom muaj txiaj ntsig zoo ntawm Micro LED zaub.
Nws tau tshaj tawm tias xyoo 2000, Nitride Semiconductors thiab xibfwb Shiro Sakai ntawm University of Tokushima hauv Nyij Pooj tau tsim lub ntiaj teb' thawj qhov ua tau zoo UV LED khoom. Txij thaum ntawd los, nws tau nqis peev ntau hauv kev tshawb fawb thiab kev tsim kho ntawm UV LED thev naus laus zis.
Hauv thawj ib nrab ntawm 2021, pab pawg tshawb fawb Nitride siv Micro UV LEDs kom zoo siab rau liab, xiav, thiab ntsuab phosphors, thiab ua tiav cov Micro UV LED chips rau 12μm x 24μm. Qhov kev ncua deb ntawm cov chips nyob rau hauv kab rov tav thiab ntsug cov lus qhia yog ob qho tib si 5μm, tuaj yeem siv rau ntawm Micro LED cov lus, thiab xav tias yuav siv rau cov khoom siv hnav xws li AR tsom iav tom ntej thiab cov tsom iav ntse.
Nitride tau hais tias cov thev naus laus zis no tuaj yeem txo tus nqi ntawm Micro UV LED chips rau cov lus qhia. Tam sim no, Nitride tab tom tsim thev naus laus zis rau kev tsim khoom loj.
