Txawm hais tias muaj ntau yam Micro LED cov khoom lag luam hauv khw, cov tuam txhab tsim khoom txuas ntxiv txhim kho cov xim liab, xiav thiab ntsuab Micro LED. Liab Micro LED chips yog ib qho ntawm cov teeb meem hauv kev tsim khoom ntawm Micro LEDs. Piv txwv li, tam sim no Nws nyuaj rau txo qhov loj ntawm cov liab LED nti mus rau 50 microns lossis tsawg dua.
Raws li kev tshaj tawm xov xwm txawv teb chaws, Nitride Semiconductors tau ua tiav kev ua haujlwm me me Micro UV LED chips rau siv hauv Micro LED cov lus. Qhov thev naus laus zis no yuav tsum tau siv rau tiam tom ntej ntawm AR tsom iav thiab tsom iav ntse.
Nws tau tshaj tawm tias pab pawg tshawb fawb Nitride Semiconductors siv Micro UV LEDs txhawm rau ua kom muaj xim liab, xiav, thiab ntsuab ntsuab, thiab thov tias txoj hauv kev no tuaj yeem txo tus nqi ntawm Micro UV LED chips rau cov lus. Tam sim no, lub tuam txhab tab tom tsim thev naus laus zis rau kev tsim khoom loj.
Raws li cov xov xwm, nti loj ntawm cov tsoos Micro UV LED yog 16μm x 48μm, qhov nrug nruab nrab ntawm cov chips hauv kab rov tav yog 10μm, thiab qhov kev ncua deb ntawm txoj kab ntsug yog 30μm. Kwv yees li 3.4 lab xws li cov chips tuaj yeem tau txais ntawm 4-nti wafer.
Nitride Semiconductors 'tshiab tsim Micro UV LED chips tsuas yog 12μm x 24μm hauv qhov loj me, thiab qhov nrug nruab nrab ntawm cov chips yog 5μm hauv ob qho tib si kab rov tav thiab ntsug. Nyob rau tib 4-nti wafer, kwv yees li 14 lab chips tuaj yeem tau txais. Qhov ntau yog 4 npaug ntawm cov tsoos Micro UV LED chips.
Hais txog tus nqi, tus nqi ntawm Nitride' tshiab Micro UV LED chips yog 1/4 ntawm tus nqi ntawm ib txwm Micro UV LED chips.
Hais txog cov yam ntxwv hluav taws xob, Nitride tau lees paub tias lub nti no muaj hluav taws xob ua tau zoo thiab tau ua tiav zoo hauv kev txhawb nqa cov ntawv thov.
Nitride tau hais tias los tsim 25 square millimeter zaub xav tau 300,000 Micro LED chips, thiab wafer tuaj yeem tsim 11 Micro LED qhia.
Nitride sib piv cov nti no rau hmoov. Lub tuam txhab thov tias qhov loj me ntawm cov hmoov nplej uas noj tau yog 10-100μm. Yog li ntawd, qhov loj me ntawm Micro UV LED nti tshiab yog ze rau qhov loj ntawm hmoov zoo.
Raws li LEDinside, xyoo 2018, Nitride Cov Khoom Siv Hluav Taws Xob tau nqis peev 100 lab nyiaj los tsim kom muaj cov koom nrog koom nrog Micro Nitride/itNitride. Lub chaw haujlwm yuav tsom mus rau R& D, kev tsim khoom thiab muag ntawm Micro UV LED chips rau Micro LED qhia.
Hauv tib lub xyoo, Nitride Semiconductors tau koom tes nrog Nyij Pooj' s V-Tech los tsim cov txheej txheem xim raws qhov hloov pauv tau yooj yim UV Micro LEDs, siv qhov tshwj xeeb" sector" cov qauv thiab cov khoom siv fluorescent kom paub cov xim xim ntawm cov zaub.
Nws tau tshaj tawm tias nyob rau thaj tsam ntawm UV LEDs, Nitride Semiconductors tau coj ua hauv kev tsim cov chips nrog lub nthwv dej ntawm 385nm thiab muaj cov peev txheej tshwj xeeb thiab kev paub dhau los.
V-Tech xaiv UV LED daws feem ntau vim tias kev ua kom pom kev zoo ntawm cov liab thiab ntsuab LEDs yuav txo qis raws li qhov loj me ntawm cov nti. Nyob rau tib lub sijhawm, V-Tech ntseeg tias, raws li kev xav, nws yog qhov tsim nyog dua los siv lub teeb luv-nthwv dej kom ua rau muaj phosphor. Kev txiav txim siab txog yam tseem ceeb xws li kev ua kom muaj txiaj ntsig zoo sab hauv, kev hloov pauv ntawm phosphor thiab kev hloov pauv ntawm yoj yoj yoj yoj, V-Tech thaum kawg xaiv Ultraviolet lub teeb nrog lub nthwv dej ntawm 385nm.
Niaj hnub no, Nitride Cov Khoom Siv Hluav Taws Xob tau ua tiav qhov ua tau zoo me me ntawm cov nti thiab txo tus nqi, tsom mus rau cov ntse ntse, nthuav tawm lub taub hau, tsom iav ntse thiab lwm yam khoom siv tau hnav, thiab npaj kom ua tiav cov khoom loj hauv xyoo 2021.
Qhov tseeb, qhov no txhais tau tias thev naus laus zis ntawm kev siv UV LEDs kom ua rau muaj kev zoo siab phosphors tau tsim los txog tam sim no, thiab kev siv thev naus laus zis ntau dua tau ua tiav. Yav tom ntej, raws li thev naus laus zis txuas ntxiv mus, nws cia siab tias yuav nthuav nws cov hneev taw hauv cov zaub thiab teeb pom kev zoo kawg. (Cov ntawv: LEDinside Janice)
