China Academy of Sciences idapanga gawo limodzi lotentha loyera la LED
Posachedwapa, Yang Bin, wothandizana nawo wofufuza wa gulu lofufuza la Dalian Institute of Chemical Physics, a Yang Bin, adagwirizana ndi Liu Feng, wofufuza wa Shandong University, kuti apange mtundu watsopano wazinthu ziwiri za perovskite zokhala ndi kuwala kwapamwamba koyera, ndipo adakonza gawo limodzi potengera nkhaniyi.Ma diode oyera oyera ofunda (LED).
Kuunikira kwamagetsi kumapangitsa 15% yamagetsi padziko lonse lapansi ndipo kumatulutsa 5% ya mpweya wowonjezera kutentha padziko lonse lapansi.Kukhazikitsidwa kwaukadaulo wowunikira bwino komanso wotsika mtengo kumatha kuchepetsa zovuta zamphamvu komanso zachilengedwe ndikuthandizira kukwaniritsa cholinga cha "double carbon".Ndi zabwino kwaflexible LED screen.Pakali pano, matekinoloje ambiri a kuwala koyera a LED makamaka amadalira ma LED a buluu kuti akondweretse mawonekedwe a fulorosenti yamitundu yambiri kuti apange kuwala koyera, kotero kuti mavuto monga kusawoneka bwino kwa mtundu, kuwala kochepa, kuwala kwa buluu, ndi kuwala koyera kosalekeza. zokonda kuchitika.Kupanga zinthu zowoneka bwino zamtundu umodzi wokhala ndi kuwala koyera kumaonedwa kuti ndizofunikira kwambiri pothetsa mavuto omwe ali pamwambawa.
Ofufuzawo adapeza kuti zida zachitsulo zopanda lead za halide double perovskite zitha kukonzedwa mwanjira yochepetsera kutentha ndi ndalama zotsika mtengo.Kuphatikiza apo, chifukwa cha kutsekeka kwa kapangidwe kake komanso mphamvu yolumikizirana yamagetsi-phonon, zida ziwiri za perovskite zili ndi zinthu zapadera zodziwikiratu (STE), ndipo luminescence yawo yophatikizika ikuwonetsa kusintha kwakukulu kwa Stokes ndi kutulutsa kowala kwa burodibandi, potero kuwonetsa. mawonekedwe a kuwala koyera.
Pofuna kulimbikitsa kuyanjananso kwa radiation, ofufuzawo adatengeranso njira ya Sb3 + doping kuti awonjezere kuchuluka kwa kuwala koyera kuchokera pa 5% mpaka 90%.Chifukwa cha magwiridwe antchito apamwamba a optoelectronic komanso njira yabwino kwambiri yopangira zida zapawiri za perovskite, gawo limodzi lotentha loyera la LED lochokera pankhaniyi litha kukonzedwa ndi njira yosavuta yothetsera, motero, ntchitoyi ikulonjeza m'badwo wotsatira. zida zowunikira.Mapangidwewo amapereka malingaliro atsopano.
Kuwonekera kwa Apple patent patent, ma screen creases atha kudzikonza okha
Mphekesera zoti Apple ikufuna kulowa mumsika wamakina opindika apitilira kukopa chidwi chakunja kuchokera kumayiko akunja m'zaka zaposachedwa, ndipo Samsung, yomwe ili ndi malo opinda mafoni am'manja, musayerekeze kunyalanyaza.Kumayambiriro kwa Novembala, Samsung idayerekeza pamsonkhano wa ogulitsa kuti ikuyembekezeka kukhala koyambirira kwa 2024, ndipo pakhoza kukhala mwayi wowona chida chatsopano cha Apple chokhala ndi "kupinda", koma chinthu choyamba chopinda Osati foni, koma piritsi kapena laputopu.
Malinga ndi lipoti laposachedwa lochokera ku atolankhani akunja a Patently Apple, Apple yatumiza posachedwa chikalata ku US Patent ndi Trademark Office, kuwonetsa kuti ukadaulo wodziwonetsa wodzichiritsa womwe wapangidwa kwa zaka zambiri ukuyembekezeka kugwiritsidwa ntchito popinda. -zida zogwirizana.
Ngakhale zomwe zili muukadaulo wa patent sizikunena kuti zidabadwira kuti zipinda ma iPhones, zimangowonetsa kuti zitha kugwiritsidwa ntchito pa iPhones, mapiritsi kapena MacBook.Komabe, ndi chiwonetsero chaukadaulo watsopanowu, ambiri akunja amatanthauzira ngati kukonzekera pasadakhale kuti iPhone yopindika idzayambitsidwe mtsogolo.
Poganizira zaukadaulo wamakono pakadali pano, ndizovuta kupewa zopindika za foni yam'manja yokhala ndi mapangidwe opindika a concave pakugwiritsa ntchito nthawi yayitali.
Kuti apititse patsogolo luso la wogwiritsa ntchito komanso malingaliro okongoletsa omwe amayamba chifukwa cha zida zopindika, ukadaulo wakuda wopangidwa ndi Apple womwe umafuna kugwiritsa ntchito ukadaulo wokutira ndi ma conductor apadera ndi zida zodzichiritsa zokha, zomwe zitha kugwiritsidwa ntchito kuphimba gawo lakunja. cha chiwonetsero cha chipangizo.Pamene panopa ikudutsa Panthawi imodzimodziyo, pogwiritsa ntchito kuwala kapena kutentha kwa kutentha kuchokera ku chilengedwe chakunja, kudzichiritsa nokha kwa ma creases othamanga kumalimbikitsidwa.
Sizikudziwikabe kuti ukadaulo wapaderawu womwe uli ndi patenti udzagwiritsidwa ntchito liti pazida za Apple posachedwa kwambiri ikapeza kafukufuku ndi ziphaso mtsogolomo.Komabe, potengera kufotokozera kwaukadaulo wapatent, ukadaulo umaphatikizapo magawo osiyanasiyana ndipo ndizovuta kwambiri.Ndi zabwino kwatransparent LED screen.Kuphatikiza apo, patent iyi idalembedwa ndi Apple ngati ukadaulo watsopano wazinthu zagulu lapadera la projekiti, zomwe zikuwonetsa kuti Apple imayiwona yofunika kwambiri.
Tekinoloje yatsopano ya Mini/Micro LED
Zikumveka kuti 2022 Phosphors & Quantum Dots Viwanda Forum idachitikira ku San Francisco, USA kumapeto kwa mwezi watha.Panthawiyi, kampani ya zipangizo zapadera za Current, wopanga zowunikira zomera za LED, adayambitsa zatsopano zowonetsera - filimu ya phosphor, ndikuwonetsa chiwonetsero cha Mini LED backlight chokhala ndi filimu yatsopano ya phosphor.
Current Chemicals imakutira Current's TriGain™ KSF/PFS phosphor yofiyira ndi JADEluxe ™ yobiriwira yobiriwira ya phosphor mufilimu ya phosphor, ndipo imagwirizana ndi Innolux kupanga mapanelo owunikira kumbuyo a MiniLED LCD.Chiwonetsero cha Mini LED backlight chomwe chikuwonetsedwa nthawi ino chili ndi mawonekedwe amitundu yosiyana kwambiri ndi mtundu wamitundu yosiyanasiyana, ndipo pano chili pamsika.
Malinga ndi deta, Current Chemicals ali ndi zaka zopitilira 70 zakufufuza ndi chitukuko m'munda wa ma phosphor a LED, zosakaniza zapadziko lapansi ndi ma phosphor ena komanso luso lazowunikira zapamwamba kwambiri.Poyerekeza ndi wamba wa KSF phosphor, eni ake a TriGain™ KSF/PFS ofiira a phosphor ali ndi mphamvu yoyamwa mwamphamvu komanso yodalirika, yomwe imathandizira zowunikira za CRI 90 ndi zowonetsera zowunikira za LED kuti zikhale zofiira komanso zowoneka bwino.
Current Chemicals akukhulupirira kuti filimu yatsopano ya phosphor yophatikiza TriGain™ KSF/PFS red phosphor ndi JADEluxe ™ yobiriwira yaphosphor yobiriwira itenga gawo lofunikira pakuwonetsa kwa Mini/Micro LED.
