Suav Academy ntawm Sciences tau tsim ib qho khoom siv sov dawb LED
Tsis ntev los no, Yang Bin, tus kws tshawb fawb ntawm lub complex molecular system tshuaj tiv thaiv dynamics tshawb fawb pab pawg ntawm Dalian Institute of Chemical Physics, koom tes nrog Liu Feng, tus kws tshawb fawb ntawm Shandong University, los tsim ib hom tshiab ntawm ob chav perovskite khoom nrog high-efficiency dawb lub teeb emission, thiab npaj ib qho khoom ua ke raws li cov khoom siv no.Sov dawb lub teeb emitting diodes (LED).
Cov teeb pom kev zoo hluav taws xob suav nrog 15% ntawm kev siv hluav taws xob thoob ntiaj teb thiab tso tawm 5% ntawm lub ntiaj teb lub tsev cog khoom gases.Kev siv cov cuab yeej siv hluav taws xob zoo dua thiab nqi qis tuaj yeem txo lub zog thiab ib puag ncig kev kub ntxhov thiab pab ua kom tiav lub hom phiaj "ob chav carbon".Nws yog qhov zoo rausaj zawg zog coj screen.Tam sim no, feem ntau lub teeb dawb LED thev naus laus zis feem ntau tso siab rau lub teeb xiav LEDs kom zoo siab rau ntau lub ntsiab lus fluorescent superposition los tsim lub teeb dawb, yog li cov teeb meem xws li cov xim tsis zoo, tsis muaj luminous efficiency, siab teeb meem xiav lub teeb, thiab tsis tu ncua lub teeb dawb spectrum. nquag tshwm sim.Kev txhim kho cov khoom siv hluav taws xob ib leeg-cov khoom siv hluav taws xob zoo yog suav tias yog tus yuam sij los daws cov teeb meem saum toj no.
Cov kws tshawb nrhiav pom tias cov hlau tsis muaj hlau lead halide ob chav perovskite cov ntaub ntawv tuaj yeem npaj tau rau hauv cov txheej txheem kev daws teeb meem nrog cov nqi qis.Tsis tas li ntawd, vim yog kev kaw ntawm nws tus kheej cov qauv thiab muaj zog hluav taws xob-phonon coupling nyhuv, ob chav perovskite cov ntaub ntawv muaj nws tus kheej-traped excitonic zog (STE), thiab lawv cov luminescence puas qhia tau hais tias ib tug loj Stokes hloov thiab broadband lub teeb emission, yog li nthuav tawm. cov yam ntxwv ntawm lub teeb dawb emission.
Txhawm rau txhawb nqa hluav taws xob rov ua dua tshiab, cov kws tshawb fawb ntxiv tau txais ib txoj kab Sb3+ doping lub tswv yim los ua kom cov quantum efficiency ntawm lub teeb dawb ntawm 5% mus rau ntau tshaj 90%.Vim lub siab optoelectronic kev ua tau zoo thiab kev daws teeb meem zoo heev ntawm kev npaj cov khoom siv tsawg-dimensional ob chav perovskite, ib qho khoom siv sov dawb LED raws li cov khoom siv no tuaj yeem npaj los ntawm txoj kev daws teeb meem yooj yim, yog li, txoj haujlwm no tau cog lus rau lwm tiam. cov khoom siv teeb pom kev zoo.Tus tsim muab tswv yim tshiab.
Apple's folding screen patent raug, screen creases tej zaum yuav kho tus kheej
Cov lus xaiv hais tias Apple npaj siab nkag mus rau lub lag luam folding tshuab tau txuas ntxiv nyiam cov neeg sab nrauv hauv xyoo tas los no, thiab Samsung, uas muaj qhov chaw hauv folding lub xov tooj, tsis xav tsis quav ntsej nws.Thaum pib lub Kaum Ib Hlis, Samsung tau kwv yees ntawm lub rooj sib tham rau cov neeg xa khoom uas xav tias yuav ntxov li xyoo 2024, thiab tej zaum yuav muaj lub sijhawm pom Apple thawj cov khoom tshiab nrog "folding" tsim, tab sis thawj cov khoom folding tsis yog. xov tooj, tab sis ib ntsiav tshuaj lossis laptop.
Raws li tsab ntawv tshaj tawm tshiab los ntawm cov xov xwm txawv teb chaws Patently Apple, Apple tsis ntev los no tau ua ib daim ntawv thov nrog US Patent thiab Trademark Office, qhia tias cov tshuaj ntsuam crease self-kho zaub technology uas tau tsim los rau ntau xyoo yuav tsum tau siv rau folding. -Cov khoom siv ntsig txog.
Txawm hais tias cov ntsiab lus ntawm patent thev naus laus zis tsis hais tshwj xeeb tias nws tau yug los rau folding iPhones, nws tsuas yog taw qhia tias nws tuaj yeem siv rau iPhones, ntsiav tshuaj lossis MacBooks.Txawm li cas los xij, nrog rau kev nthuav tawm ntawm cov cuab yeej tshiab no, feem ntau ntawm lub ntiaj teb sab nraud txhais nws ua kev npaj ua ntej rau lub folding iPhone yuav tsum tau nthuav tawm yav tom ntej.
Nyob rau hauv kev saib ntawm cov cuab yeej tam sim no nyob rau theem no, nws yog qhov nyuaj kom tsis txhob muaj creases rau lub xov tooj ntawm tes folding nrog lub concave folding tsim nyob rau lub sij hawm ntev ntawm kev siv.
Txhawm rau txhim kho cov neeg siv kev paub thiab kev xav zoo nkauj tshwm sim los ntawm creases tshwm sim los ntawm cov khoom siv folding, cov tshuab dub tsim los ntawm Apple nws tus kheej hu rau kev siv cov txheej txheem txheej txheej nrog cov khoom tshwj xeeb thiab cov khoom siv kho tus kheej, uas tuaj yeem siv los npog txheej txheej. ntawm tus ntaus ntawv tso saib.Thaum qhov tam sim no dhau los ntawm tib lub sijhawm, los ntawm kev siv lub teeb lossis kub stimulation los ntawm ib puag ncig sab nraud, kev kho tus kheej ntawm kev nrawm nrawm yog txhawb nqa.
Nws tseem tsis tau paub tias thaum twg qhov tshwj xeeb patented thev naus laus zis no yuav raug siv rau Apple li sai tshaj plaws tom qab nws tau txais kev tshuaj xyuas thiab ntawv pov thawj yav tom ntej.Txawm li cas los xij, kev txiav txim siab los ntawm cov lus piav qhia ntawm patented thev naus laus zis, thev naus laus zis suav nrog ntau qib thiab nyuaj heev.Nws yog qhov zoo raupob tshab coj screen.Tsis tas li ntawd, daim ntawv pov thawj no tau teev tseg los ntawm Apple raws li cov khoom siv thev naus laus zis tshiab uas koom nrog pawg tshwj xeeb project, uas qhia tau tias Apple tseem ceeb heev rau nws.
Mini / Micro LED cov khoom siv technology tshiab
Nws tau nkag siab tias 2022 Phosphors & Quantum Dots Kev Lag Luam Lub Rooj Sab Laj tau muaj nyob hauv San Francisco, Tebchaws Asmeskas thaum kawg ntawm lub hli tas los.Thaum lub sij hawm lub sij hawm, lub tuam txhab cov ntaub ntawv tshwj xeeb ntawm tam sim no, ib tug LED cog teeb pom kev zoo chaw tsim tshuaj paus, launched ib tug tshiab zaub cov ntaub ntawv - phosphor zaj duab xis, thiab pom ib tug Mini LED backlight zaub nruab nrog ib tug tshiab phosphor zaj duab xis.
Cov tshuaj tam sim no encapsulates Tam sim no tus TriGain™ KSF/PFS liab phosphor thiab tshiab JADEluxe™ nqaim-band ntsuab phosphor nyob rau hauv phosphor zaj duab xis, thiab koom tes nrog Innolux los tsim MiniLED LCD backlight panels.Mini LED backlight zaub tso tawm lub sijhawm no muaj cov yam ntxwv ntawm qhov sib txawv siab thiab dav xim gamut, thiab tam sim no nyob rau hauv kev ua lag luam.
Raws li cov ntaub ntawv, Tam sim no Tshuaj muaj ntau tshaj li 70 xyoo ntawm kev tshawb fawb thiab kev loj hlob kev nyob rau hauv lub teb ntawm LED phosphors, tsis tshua muaj lub ntiaj teb tebchaw thiab lwm yam phosphors thiab high-purity luminescent cov ntaub ntawv innovation.Piv nrog rau tus qauv KSF phosphor, nws tus tswv TriGain ™ KSF / PFS liab phosphor muaj lub peev xwm nqus tau zoo thiab kev ntseeg tau zoo dua, uas pab CRI 90 cov khoom siv teeb pom kev zoo thiab LED backlight qhia kom ua tiav cov nplua nuj thiab vivid liab.
Cov tshuaj tam sim no ntseeg tias cov yeeb yaj kiab tshiab phosphor sib txuas TriGain ™ KSF / PFS liab phosphor thiab JADEluxe ™ nqaim-band ntsuab phosphor yuav ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm Mini / Micro LED zaub.
