Cov kua siv lead ua kua (LCD) yog ib feem tseem ceeb ntawm TVs niaj hnub, smartphones thiab ntsiav tshuaj.In LCD cov ntxaij vab tshaus, lub teeb-emitting diodes (LEDs) tsim lub teeb dawb tom qab, uas yog tom qab irradiated rau tus saib los ntawm ib tug ultra-nyias kua siv lead ua txheej. Cov txheej txheem siv lead ua tau muab faib ua ntau ntu (pixels), thiab lawv qhov sib kis ntawm lub teeb tuaj yeem hloov kho los ntawm kev siv hluav taws xob teb. Nyob rau hauv txoj kev no, txhua pixel emits lub teeb nrog nws qhov tshwj xeeb ci ci (thiab cov xim nthuav tawm los ntawm cov xim lim).
Hauv cov vaj huam sib luag tiaj tus uas nruab nrog cov LEDs ib txwm muaj, qhov tsim nyog backlight yog tsim los ntawm ntau pua LEDs; Txij li thaum ib qho LED yuav tsum muaj qhov chaw loj heev, nws tsis yooj yim sua kom muaj qhov chaw ntau dua.Qhov tsis zoo yog qhov pom tseeb: nws tsis yooj yim sua kom ua tiav cov teeb pom kev zoo ntawm LCD lub teeb pom kev zoo nrog xws li ntxhib LED matrix.Yog li ntawd, thaum thawj batch ntawm cov ntxaij vab tshaus txais yuav tshiab mini-LED thev naus laus zis tuaj tawm xyoo 2020, kev lag luam tau txhawb nqa kev txaus siab heev.Vim tias cov mini-LEDs me me heev (0.05 txog 0.2 hli) piv rau cov LEDs ib txwm muaj, tam sim no nws muaj peev xwm tsim cov teeb pom kev zoo los ntawm kaum tawm txhiab tus mini-LED teeb. Qhov chaw.Mini LEDs tau ntim rau hauv qhov hu ua teeb pom kev zoo, qhov twg txhua cheeb tsam tseem me dua li cov LEDs ib txwm muaj.Los ntawm kev tswj hwm ntawm txhua cheeb tsam, piv nrog cov tsoos LEDs, lub teeb pom kev zoo tuaj yeem tswj tau zoo dua spatially.Yog li ntawd, TV saib tau cia siab tias yuav txhim kho qhov sib txawv thiab qhov sib sib zog nqus tob dua. Tsis tas li ntawd, mini-LED thev naus laus zis yog qhov zoo ntawm kev tsim cov khoom siv hluav taws xob siab heev (HDR) thiab kev siv hluav taws xob qis dua.
Kev tsim cov LEDs lossis mini-LEDs yog qhov nyuaj dua li qhov yooj yim ntawm qhov chaw cuam tshuam los ntawm cov khoom siv - tshwj xeeb yog vim qee qhov tsim nyog tsim cov kauj ruam yuav tsum tau ua raws li lub tshuab nqus tsev. Cov txheej txheem no yog siv los txheej txheej hlau organic rau ntawm wafer.Nyob rau hauv cov txheej txheem no, cov txheej txheem txheej yog txuas rau cov siv lead ua lattice uas twb muaj lawm nyob rau hauv ib qho kev txiav txim atomically: tsuas yog ob peb atomic txheej tuab, uas tshwm sim los txais yuav cov qauv siv lead ua ntawm wafer. .Los xyuas kom meej tias cov txheej txheem tsis muaj impurities, cov txheej txheem no yuav tsum tau ua raws li kev tiv thaiv lub tshuab nqus tsev.Qhov no yog qhov uas tus nqi-ntxiv cov nqi se tawm los rau hauv kev ua si.Lub ntiaj teb cov chaw tsim khoom loj tshaj plaws ntawm MOCVD systems-nrog lub tuam txhab lub hauv paus hauv lub teb chaws Yelemees, Tuam Tshoj, thiab Tebchaws Meskas - tso siab rau VAT lub tshuab nqus tsev vacuum.
Yuav kom tsim tau qhov zoo-tsis zoo hloov dua siab tshiab nyob rau hauv lub LED, ib tug ntxiv ultra-nyias txheej yuav tsum tau muab tso rau thiab ces etched tam sim ntawd nyob rau hauv qhov tseeb txoj hauj lwm.Qhov no ilv ua hauj lwm yog ua kom tiav zoo tshaj plaws los ntawm kev sib cuam tshuam ntawm ob plasma-txhim kho nyias zaj duab xis txheej txheem: plasma- enhanced chemical vapor deposition (PECVD) rau depositing txheej, thiab plasma tshuaj qhuav etching rau ib nrab tshem tawm ntawm lawv.Vim cov txheej txheem no kuj yuav tsum tau ua nyob rau hauv lub tshuab nqus tsev, VAT lub tshuab nqus tsev valve kuj plays lub luag hauj lwm tseem ceeb ntawm no.
Thaum muaj kev cuam tshuam tiag tiag tshwm sim yav tom ntej, VAT li qub yuav dhau los ua ib qho ntawm lawv.Tom qab tag nrho, raws li cov kws tshaj lij, mini-LEDs tsuas yog qhov chaw nres tsheb rau lub teeb me me: micro-LEDs.Piv nrog mini-LEDs, cov no Cov khoom me me muaj tseeb yog 50 txog 100 npaug me dua.Tshwj xeeb: qhov tam sim no me me micro-LED muaj ib sab ntev ntawm 3 microns, uas yog peb txhiab ntawm ib millimeter! Tab sis nws tsis yog qhov sib txawv me me uas ua rau micro LEDs tshwj xeeb. Ntawm qhov contrary, micro-LED technology sawv cev rau qhov tseeb paradigm hloov.Piv nrog LCD cov ntxaij vab tshaus, (mini) LEDs ua si ib tug es inconspicuous theem nrab lub luag hauj lwm raws li ib tug tom qab lub teeb qhov chaw. Nyob rau hauv micro LED cov ntxaij vab tshaus, txhua pixel yog nws tus kheej-luminous, dimmable thiab yuav tsum tau kiag li muab tua.Qhov ntxiv backlight-thiab cov kev cuam tshuam kev tsis paub meej-yog li tsis xav tau lawm!
Txawm hais tias Micro-LED yog me me, cov nyhuv loj heev.Qhov kev hloov ntawm micro mus rau micro LED thev naus laus zis tau coj cov txiaj ntsig zoo.Ib txhia ntawm lawv pom, xws li cov xim loj dua, lub teeb ci dua, qhov sib txawv ntawm qhov sib txawv, thiab qhov ceev refresh npaum li cas.Lwm tus, xws li kev siv hluav taws xob qis dua thiab lub neej ntev dua, tsis muaj teeb meem, tab sis qhov tseem ceeb sib npaug.Nyob rau hauv cov ntsiab lus no, lub cim tshiab ntawm LEDs yuav dhau los ua qhov hloov pauv tau tiag tiag.
VAT Group AG tau tshaj tawm cov ntsiab lus no thaum Lub Kaum Ob Hlis 14, 2021, thiab tsuas yog lub luag haujlwm rau cov ntaub ntawv muaj nyob hauv nws.Tshwj xeeb los ntawm cov pej xeem thaum 06: 57: 28 thaum Lub Kaum Ob Hlis 14, 2021, sijhawm UTC, tsis kho thiab tsis hloov pauv.
