I-Chinese Academy of Sciences ithuthukise i-LED emhlophe efudumele enengxenye eyodwa
Muva nje, u-Yang Bin, umcwaningi ohlangene weqembu eliyinkimbinkimbi le-molecular reaction reaction dynamics ye-Dalian Institute of Chemical Physics, ubambisene no-Liu Feng, umcwaningi waseShandong University, ukuthuthukisa uhlobo olusha lwezinto eziphindwe kabili ze-perovskite ezinokukhishwa kokukhanya okumhlophe okusebenza kahle kakhulu, futhi yalungiselela ingxenye eyodwa esekelwe kulolu lwazi.Ama-diode amhlophe afudumele akhipha ukukhanya (LED).
Izibani zikagesi zibalelwa ku-15% wokusetshenziswa kukagesi emhlabeni wonke futhi zikhipha ama-5% amagesi abamba ukushisa emhlabeni.Ukwamukelwa kobuchwepheshe bokukhanyisa obusebenza kahle kakhulu nobunezindleko eziphansi kungadambisa izinkinga zamandla nemvelo futhi kusize ukufeza umgomo "wekhabhoni ephindwe kabili".Ilungeleisikrini esiholayo esivumelana nezimo.Njengamanje, ubuchwepheshe obuningi bokukhanya okumhlophe kwe-LED ikakhulukazi buthembele kuma-LED aluhlaza okwesibhakabhaka ukuze athokozise i-multi-component fluorescent superposition ukukhiqiza ukukhanya okumhlophe, ngakho-ke izinkinga ezinjengokunikezwa kombala okungekuhle, ukusebenza kahle kokukhanya okuphansi, izingxenye zokukhanya eziluhlaza okwesibhakabhaka eziyingozi, kanye ne-spectrum yokukhanya okumhlophe okungaqhubeki. kujwayele ukwenzeka.Ukuthuthukiswa kwezinto ezisebenza kahle kakhulu zokukhanya okumhlophe okuyingxenye eyodwa kubhekwa njengesihluthulelo sokuxazulula izinkinga ezingenhla.
Abacwaningi bathola ukuthi izinto ze-lead-free metal halide double perovskite zingalungiswa ngendlela yesisombululo esisezingeni eliphansi nezindleko zokukhiqiza eziphansi.Ukwengeza, ngenxa yokuvalelwa kwesakhiwo sayo kanye nomphumela oqinile wokuhlanganisa kagesi-phonon, izinto zokwakha ze-perovskite zinezakhiwo eziyingqayizivele ezizibambelekelayo ze-excitonic (STE), futhi i-luminescence yazo ehlanganisiwe ibonisa ukushintsha okukhulu kwe-Stokes kanye nokukhishwa kokukhanya kwe-broadband, ngaleyo ndlela kubonise. izici zokukhishwa kokukhanya okumhlophe.
Ukuze kukhuthazwe ukuhlanganisa kabusha kwemisebe, abacwaningi baphinde bamukela isu le-doping le-Sb3+ lokukhulisa ukusebenza kahle kwe-quantum yokukhanya okumhlophe kusuka ku-5% kuya ngaphezulu kwama-90%.Ngenxa yokusebenza okuphezulu kwe-optoelectronic kanye nokusebenza kahle kwesixazululo sezinto ezilungisiwe ze-perovskite eziphindwe kabili ezilungiselelwe, ingxenye eyodwa ye-LED efudumele efudumele esekelwe kulokhu kwaziswa ingalungiswa ngendlela elula yesisombululo, ngakho-ke, lo msebenzi uthembisa isizukulwane esilandelayo. amadivaysi okukhanyisa.Idizayini inikeza imibono emisha.
Ukuchayeka kwelungelo lobunikazi besikrini esigoqayo se-Apple, ama-crease creases angase azilungise wona
Amahemuhemu okuthi i-Apple ihlose ukungena emakethe yomshini wokugoqa aqhubekile nokuheha ukunakwa okuphezulu okuvela emhlabeni wangaphandle eminyakeni yamuva nje, futhi abakwaSamsung, abanendawo yokugoqa omakhalekhukhwini, bangalinge bazibe.Ekuqaleni kukaNovemba, abakwaSamsung balinganisela emhlanganweni wabahlinzeki ukuthi kulindeleke ukuthi baqale ngo-2024, futhi kungase kube nethuba lokubona umkhiqizo omusha we-Apple onomklamo "ogoqayo", kodwa umkhiqizo wokuqala wokugoqa Not a. ifoni, kodwa ithebhulethi noma ikhompyutha ephathekayo.
Ngokombiko wakamuva ovela kwabezindaba zakwamanye amazwe u-Patently Apple, i-Apple isanda kufaka isicelo sedokhumenti e-US Patent and Trademark Office, ebonisa ukuthi ubuchwepheshe bokuzibonakalisa be-screen crease obuthuthukisiwe iminyaka eminingi kulindeleke ukuthi busetshenziswe ekugoqeni. -amadivayisi ahlobene.
Yize okuqukethwe kobuchwepheshe belungelo lobunikazi kungasho ngokuqondile ukuthi yazalelwa ukugoqa ama-iPhone, ikhomba kuphela ukuthi ingasetshenziswa kuma-iPhone, amaphilisi noma ama-MacBooks.Kodwa-ke, ngokuvezwa kwale patent entsha yobuchwepheshe, iningi labantu bangaphandle likuhumusha njengokulungiselela kusengaphambili i-iPhone esongwayo ezokwethulwa ngokuzayo.
Ngenxa yobuchwepheshe bamanje kulesi sigaba, kunzima ukugwema ama-creases eselula egoqayo enomklamo wokugoqa we-concave esikhathini eside sokusetshenziswa.
Ukuze kuthuthukiswe isipiliyoni somsebenzisi kanye nokucatshangelwa kobuhle okubangelwa ama-creases abangelwa amadivayisi agoqayo, ubuchwepheshe obumnyama obuthuthukiswe yi-Apple ngokwayo bufuna ukusetshenziswa kobuchwepheshe bokumboza ngama-conductor akhethekile nezinto zokuziphulukisa, ezingasetshenziswa ukumboza ungqimba lwangaphandle. kwesibonisi sedivayisi.Lapho i-current idlula Ngesikhathi esifanayo, ngokusebenzisa ukukhanya noma ukushisa okushisa okuvela endaweni yangaphandle, umphumela wokuziphilisa we-accelerated creases uyakhuthazwa.
Okwamanje akwaziwa ukuthi lobu buchwepheshe obukhethekile obunelungelo lobunikazi buzosetshenziswa nini kumadivayisi e-Apple ngokushesha nje ngemva kokuthola ukuhlolwa nokuqinisekiswa ngokuzayo.Kodwa-ke, uma sibheka encazelweni yobuchwepheshe obunelungelo lobunikazi, ubuchwepheshe bubandakanya amazinga anhlobonhlobo futhi buyindida.Ilungeleisikrini esiholela esobala.Ngaphezu kwalokho, leli lungelo lobunikazi libhalwe yi-Apple njengobuchwepheshe bomkhiqizo obusha beqembu lephrojekthi ekhethekile, okubonisa ukuthi i-Apple ibheka ukubaluleka okukhulu kuyo.
Ubuchwepheshe obusha be-Mini/Micro LED
Kuyaqondakala ukuthi i-2022 Phosphors & Quantum Dots Industry Forum ibibanjelwe eSan Francisco, e-USA ekupheleni kwenyanga edlule.Phakathi naleso sikhathi, inkampani yezinto ezikhethekile zamanje, umkhiqizi wokukhanyisa izitshalo ze-LED, yethula into entsha yokubonisa - ifilimu ye-phosphor, futhi yabonisa isibonisi se-Mini LED backlight esifakwe ifilimu entsha ye-phosphor.
Amakhemikhali Amanje ahlanganisa i-Current's TriGain™ KSF/PFS phosphor ebomvu kanye ne-JADEluxe™ enamabhande aluhlaza ane-phosphor eluhlaza efilimini ye-phosphor, futhi ibambisana ne-Innolux ukwenza amaphaneli okukhanya angemuva e-MiniLED LCD.Isibonisi se-Mini LED backlight esiboniswa ngalesi sikhathi sinezici zokugqama okuphezulu kanye ne-gamut yombala obanzi, futhi okwamanje sisemakethe.
Ngokusho kwedatha, Amakhemikhali Amanje aneminyaka engaphezu kwengu-70 yocwaningo kanye nesipiliyoni sokuthuthukiswa emkhakheni we-phosphors ye-LED, izinhlanganisela zomhlaba ezingavamile kanye namanye ama-phosphor kanye nokusungulwa kwezinto ezintsha zokukhanya kwe-luminescent.Uma kuqhathaniswa ne-phosphor evamile ye-KSF, i-TriGain™ KSF/PFS i-phosphor ebomvu ephathelene nayo inamandla okumunca aqinile nokuthembeka okungcono, esiza imikhiqizo yokukhanyisa ye-CRI 90 kanye nezibonisi ze-backlight ze-LED ukuze kuzuzwe okubomvu okucebile nokucacile.
Amakhemikhali Amanje akholelwa ukuthi ifilimu entsha ye-phosphor ehlanganisa i-TriGain™ KSF/PFS i-phosphor ebomvu ne-JADEluxe™ i-narrow-band green phosphor izodlala indima ebalulekile emkhakheni wezibonisi ze-Mini/Micro LED.
