Akadeemiyada Sayniska ee Shiinaha ayaa soo saartay LED cad oo diirran
Dhawaan, Yang Bin, oo ah cilmi-baare associate of the complex molecular reaction reactions dynamics group research group of Dalian Institute of Chemical Physics, oo la kaashaday Liu Feng, cilmi baare ka tirsan Jaamacadda Shandong, si loo horumariyo nooc cusub oo perovskite double perovskite oo leh hufnaan sare oo iftiin cad ah, waxayna diyaariyeen hal qayb oo ku salaysan walxahan.Diirarka iftiinka cad ee diirran (LED).
Iftiinka korantada ayaa 15% ka ah isticmaalka korontada adduunka waxayna sii daayaan 5% gaaska aqalka dhirta lagu koriyo.Qaadashada tignoolajiyada iftiiminta ee waxtarka badan iyo qiimaha jaban waxay yareyn kartaa tamarta iyo dhibaatooyinka deegaanka waxayna gacan ka geysan kartaa gaaritaanka yoolka "kaarboon laba jibaaran".Way u fiican tahayShaashada hogaaminaysa dabacsan.Waqtigan xaadirka ah, inta badan tikniyoolajiyada iftiinka cad ee LED waxay inta badan ku tiirsan yihiin nalalka buluuga ah ee iftiinka buluugga ah si ay u kiciyaan qaybo badan oo fluorescent superposition si ay u soo saaraan iftiin cad, markaa dhibaatooyinka sida midabaynta liidata, waxtarka iftiinka hooseeya, qaybaha iftiinka buluuga ah ee waxyeellada leh, iyo iftiinka iftiinka cad ee joogsan waa u nugul inay dhacaan.Horumarinta wax ku oolnimada sare ee hal qayb oo ka kooban walxaha iftiinka cad ayaa loo tixgeliyaa inay yihiin furaha xallinta dhibaatooyinka kor ku xusan.
Cilmi-baadhayaashu waxay ogaadeen in birta birta ah ee aan macdanta "lead-free" ee qalabka perovskite double lagu diyaarin karo habka xalalka heerkulka hooseeya oo leh kharash yar oo wax soo saar ah.Intaa waxaa dheer, sababtoo ah xannibaadda qaab-dhismeedkeeda iyo saameynta xooggan ee isku-xidhka koronto-phonon, maaddooyinka perovskite double waxay leeyihiin sifooyin gaar ah oo is-xakamaysan (STE), iyo iftiinkooda isku-dhafka ah waxay muujinayaan isbeddel weyn oo Stokes ah iyo qiiqa iftiinka ballaaran, si ay u muujiyaan sifooyinka iftiinka cad ee sii daaya.
Si kor loogu qaado dib-u-habaynta shucaaca, cilmi-baarayaashu waxay sii qaateen raadraaca Sb3+ istaraatijiyad doping si loo kordhiyo waxtarka tirada iftiinka cad ee 5% ilaa in ka badan 90%.Iyada oo ay ugu wacan tahay waxqabadka sare ee optoelectronic iyo mashiinnada xalka aadka u wanaagsan ee diyaarsan laba-geesoodka perovskite-ga hooseeya, hal-qayb-ka kooban LED diirran oo cad oo ku saleysan maaddadan ayaa lagu diyaarin karaa hab xal fudud, sidaas darteed, shaqadani waxay rajo u tahay jiilka soo socda. qalabka iftiinka.Naqshadu waxay bixisaa fikrado cusub.
Shaashada laablaaban ee Apple ee soo-gaadhista shatiga, muraayadaha shaashadda ayaa laga yaabaa inay is-dayactirto
Wararka xanta ah ee sheegaya in Apple ay doonayso inay gasho suuqa mashiinnada isku laabma ayaa sannadihii u dambeeyay soo jiidanayay indhaha caalamka oo dhan, Samsung, oo boos ku leh isku-laabashada talefannada gacanta, ayaa ku dhiirran inay iska indhatiraan.Bilowgii Nofembar, Samsung waxay ku qiyaastay shirka alaab-qeybiyeyaasha in la filayo inuu dhaco horraanta 2024, waxaana laga yaabaa inay jirto fursad lagu arko badeecada cusub ee Apple ee ugu horreysa oo leh nashqad "lalaabid", laakiin badeecada ugu horreysa ee isku laabma maaha telefoonka, laakiin tablet ama laptop.
Sida laga soo xigtay warbixintii ugu dambeysay ee warbaahinta ajnabiga ah ee Patent Apple, Apple ayaa dhawaan xareeyay codsi dukumeenti ah Xafiiska Patent and Trademark US, taas oo muujinaysa in shaashadda tignoolajiyada is-bogsiinta is-bogsiinta oo la sameeyay sannado badan la filayo in lagu dabaqo isku laabma -qalabka la xiriira.
In kasta oo nuxurka tignoolajiyada patent-ku aanay si gaar ah u xusin in ay ku dhalatay laalaabida iPhones, waxa ay tilmaamaysaa oo keliya in lagu dabaqi karo iPhones, tablets ama MacBooks.Si kastaba ha noqotee, soo bandhigida shatiyada cusub ee tignoolajiyada, inta badan adduunka ka baxsan waxay u tarjumeysaa diyaargarow horudhac ah oo loogu talagalay iPhone-ka laalaabka ah ee la bilaabayo mustaqbalka.
Marka la eego tignoolajiyada hadda jirta marxaladan, way adagtahay in laga fogaado xuubka taleefanka gacanta oo leh nashqad isku laabma oo isku laabma muddada dheer ee isticmaalka.
Si loo wanaajiyo khibrada isticmaalaha iyo tixgelinta bilicda leh ee ay sababto qulqulka ay sababaan aaladaha laalaabka, tignoolajiyada madow ee ay samaysay Apple lafteedu waxay ku baaqaysaa isticmaalka tignoolajiyada dahaarka leh kirishbooyada gaarka ah iyo walxaha is-bogsiinta, kaas oo loo isticmaali karo in lagu daboolo lakabka sare. ee bandhiga qalabka.Marka uu hadda maraayo Isla mar ahaantaana, iyada oo loo marayo isticmaalka iftiinka ama kicinta heerkulka deegaanka dibadda, saameynta is-bogsiinta ee xajinta degdega ah ayaa kor loo qaadayaa.
Ilaa hadda lama garanayo goorta tignoolajiyadan gaarka ah ee rukhsadda leh lagu dabaqi doono aaladaha Apple sida ugu dhaqsaha badan kadib marka ay hesho hantidhawrka iyo shahaado bixinta mustaqbalka.Si kastaba ha noqotee, marka laga eego sharraxaadda tignoolajiyada patent-ka, tignoolajiyadu waxay ku lug leedahay heerar kala duwan oo aad u adag.Way u fiican tahayshaashad hufnaan leh.Intaa waxaa dheer, patent-kan waxa ay Apple ku taxay sida tignoolajiyada cusub ee wax soo saarka ee ka tirsan kooxda mashruuca gaarka ah, taas oo muujinaysa in Apple ay muhiimad weyn siiso.
Mini/Mikro LED tignoolajiyada alaabta cusub
Waxaa la fahamsan yahay in 2022 Phosphors & Quantum Dots Forum Warshadaha lagu qabtay San Francisco, USA dhamaadkii bishii hore.Inta lagu jiro muddadaas, shirkadda qalabka gaarka ah ee Current, oo ah soo saaraha iftiinka dhirta LED, ayaa bilaabay qalab cusub - filim fosfoor ah, oo soo bandhigay muraayad mini LED ah oo ku qalabaysan filim fosfoor cusub.
Kiimikooyinka hadda jira waxay koobayaan TriGain ™ KSF/PFS fosfoor cas iyo JADEluxe ™ cusub fosfoor cagaaran oo cidhiidhi ah oo ku jira filim fosfoor ah, waxayna la shaqeeyaan Innolux si ay u soo saaraan muraayadaha MiniLED LCD.Bandhiga nalka dambe ee Mini LED ee la soo bandhigay wakhtigan waxa uu leeyahay sifooyin kala duwanaansho sare ah iyo gamut midab ballaadhan, waxana uu hadda ku jiraa suuqa.
Marka loo eego xogta, Kiimikada hadda jirta waxay leedahay in ka badan 70 sano oo cilmi baaris iyo waayo-aragnimo horumarineed ah oo ku saabsan duurka fosfooraska LED, xeryahooda naadirka ah ee dhulka iyo fosfooraska kale iyo ikhtiraacida agabka iftiinka sare leh.Marka la barbardhigo fosfoorka caadiga ah ee KSF, TriGain ™ KSF/PFS fosfoor cas oo leh awood nuugista oo xooggan iyo isku halleyn wanaagsan, taas oo ka caawisa CRI 90 alaabta iftiinka iyo soo-bandhigidda iftiinka dambe ee LED si loo gaaro taajir iyo casaan cad.
Kiimikooyinka hadda jira waxay aamminsan yihiin in filimka fosfoorka cusub ee isku daraya TriGain ™ KSF/PFS fosfoor cas iyo JADEluxe ™ fosfoor cagaaran oo cidhiidhi ah ay door muhiim ah ka ciyaari doonaan bandhigyada Mini/Micro LED.
