I-Academy yaseTshayina yeSayensi iphuhlise icandelo elinye elifudumeleyo le-LED emhlophe
Kutshanje, uYang Bin, umphandi onxulumene nenkqubo ye-molecular reaction dynamics yophando iqela le-Dalian Institute of Chemical Physics, ibambisene noLiu Feng, umphandi weYunivesithi yaseShandong, ukuphuhlisa uhlobo olutsha lwezinto eziphindwe kabini ze-perovskite kunye nokukhutshwa kokukhanya okumhlophe okuphezulu, kwaye ulungiselele icandelo elinye elisekelwe kulo mbandela.Iidiode zokukhanya ezimhlophe ezifudumeleyo (LED).
Izibane zombane zibalelwa kwi-15% yokusetyenziswa kombane kwihlabathi kwaye zikhupha i-5% yeegesi ze-greenhouse zehlabathi.Ukwamkelwa kweteknoloji yokukhanyisa esebenzayo kunye nexabiso eliphantsi kunokunciphisa amandla kunye neengxaki zokusingqongileyo kunye nokunceda ukufezekisa injongo "yekhabhoni ephindwe kabini".Ilungeleisikrini esikhokelayo esiguqukayo.Okwangoku, uninzi lwetekhnoloji yokukhanya okumhlophe kwe-LED ubukhulu becala ixhomekeke kukukhanya okuluhlaza kwe-LEDs ukonwabisa i-multi-component fluorescent superposition ukuvelisa ukukhanya okumhlophe, ke iingxaki ezinje ngokunikezela ngombala ombi, ukusebenza kakuhle kokukhanya okuphantsi, izinto ezinobungozi obuphezulu obuluhlaza, kunye nokukhanya okumhlophe okungapheliyo. iqhele ukwenzeka.Ukuphuhliswa kwezinto eziphezulu zokukhanya okumhlophe kwecandelo elilodwa kuthathwa njengento ephambili ekusombululeni ezi ngxaki zingentla.
Abaphandi bafumanisa ukuba i-lead-free metal halide i-double perovskite i-perovskite ingalungiswa ngendlela yesisombululo esisezantsi kunye neendleko eziphantsi zokuvelisa.Ukongezelela, ngenxa yokuvalelwa kwesakhiwo sayo kunye nefuthe elinamandla lombane-phonon lokudibanisa, izinto eziphindwe kabini ze-perovskite zineepropati ezizimeleyo ezizibambeleyo ze-excitonic (STE), kunye ne-luminescence yazo edibeneyo ibonisa utshintsho olukhulu lwe-Stokes kunye nokukhutshwa kokukhanya kwe-broadband, ngaloo ndlela ibonisa. iimpawu zokukhutshwa kokukhanya okumhlophe.
Ukuze kukhuthazwe ukudityaniswa kwakhona kwe-radiative, abaphandi baqhubela phambili bamkela isicwangciso se-doping se-Sb3 + sokwandisa ukusebenza kakuhle kwe-quantum yokukhanya okumhlophe ukusuka kwi-5% ukuya ngaphezulu kwe-90%.Ngenxa yokusebenza okuphezulu kwe-optoelectronic kunye nesisombululo esigqwesileyo sobuchule bezinto ezilungiselelwe eziphantsi-dimensional eziphindwe kabini ze-perovskite, icandelo elinye elifudumeleyo le-LED elimhlophe elisekwe kulo mbandela linokulungiswa ngendlela yesisombululo esilula, ke, lo msebenzi uthembisa isizukulwana esilandelayo. izixhobo zokukhanyisa.Uyilo lubonelela ngeembono ezintsha.
Ukuvezwa kwesikrini se-patent ye-Apple, iicreases zesikrini zinokuzilungisa
Amahemuhemu okuba i-Apple ijonge ukungena kwimakethi yomatshini wokusonga iqhubekile nokutsala ingqalelo ephezulu kwihlabathi langaphandle kwiminyaka yakutshanje, kwaye i-Samsung, enendawo yokusonga iifowuni eziphathwayo, musa ukuyihoya.Ekuqaleni kukaNovemba, i-Samsung iqikelele kwintlanganiso yababoneleli ukuba kulindeleke ukuba ibe ngeye-2024, kwaye kunokubakho ithuba lokubona imveliso yokuqala ye-Apple enoyilo "lokusonga", kodwa imveliso yokuqala yokusonga. ifowuni, kodwa ithebhulethi okanye ilaptop.
Ngokutsho kwengxelo yamva nje evela kumajelo angaphandle Patently Apple, Apple kutshanje ufake isicelo uxwebhu kunye US Patent kunye ne-Ofisi yoRhwebo, ebonisa ukuba isikrini crease self-ukuziphilisa iteknoloji ukubonisa eye yaphuhliswa iminyaka emininzi kulindeleke ukuba isetyenziswe ukusonga. -izixhobo ezinxulumeneyo.
Nangona umxholo wetekhnoloji yelungelo elilodwa lomenzi wechiza ungakhankanyi ngokuthe ngqo ukuba yazalelwa ukusonga ii-iPhones, iveza kuphela ukuba inokufakwa kwii-iPhones, iitafile okanye iiMacBooks.Nangona kunjalo, ngokuvezwa kwale patent entsha yetekhnoloji, uninzi lwelizwe langaphandle liyitolika njengolungiselelo lwangaphambili lwe-iPhone esongwayo eza kusungulwa kwixesha elizayo.
Ngokujonga itekhnoloji yangoku kweli nqanaba, kunzima ukunqanda i-creases yokusonga ifowuni ephathwayo kunye noyilo lwe-concave lokusonga ixesha elide lokusetyenziswa.
Ukuze kuphuculwe amava omsebenzisi kunye nokuqwalaselwa kobuhle okubangelwa yi-creases ebangelwa zizixhobo ezisongayo, itekhnoloji emnyama ephuhliswe yi-Apple ngokwayo ifuna ukusetyenziswa kwetekhnoloji yokugquma kunye nee-conductor ezikhethekileyo kunye nezinto zokuziphilisa, ezinokuthi zisetyenziswe ukugubungela umaleko wangaphandle. yomboniso wesixhobo.Xa ikhoyo ngoku idlula Ngexesha elifanayo, ngokusetyenziswa kokukhanya okanye ukufudumala kweqondo lokushisa ukusuka kwindawo yangaphandle, umphumo wokuziphilisa we-accelerated creases ukhuthazwa.
Akukaziwa ukuba obu buchwepheshe bukhethekileyo bunelungelo elilodwa lomenzi buza kusetyenziswa nini kwizixhobo ze-Apple ngokukhawuleza emva kokuba ifumene uphicotho kunye nesiqinisekiso kwixa elizayo.Nangona kunjalo, ngokujonga inkcazo yetekhnoloji enelungelo elilodwa lomenzi wechiza, itekhnoloji ibandakanya uluhlu olubanzi lwamanqanaba kwaye inzima kakhulu.Ilungeleisikrini esikhokelela elubala.Ukongeza, le patent idweliswe yiApple njengetekhnoloji entsha yemveliso eyeqela leprojekthi ekhethekileyo, ebonisa ukuba iApple ibaluleke kakhulu kuyo.
Itekhnoloji yemathiriyeli encinci / encinci ye-LED
Kuyaqondwa ukuba i-2022 Phosphors & Quantum Dots Industry Forum yabanjwa eSan Francisco, eU.SA ekupheleni kwenyanga ephelileyo.Ngeli xesha, inkampani yezixhobo ezikhethekileyo zangoku, umenzi wokukhanyisa isityalo se-LED, uqalise into entsha yokubonisa - ifilimu ye-phosphor, kwaye yabonisa i-Mini LED backlight display exhotywe ngefilimu entsha ye-phosphor.
Iikhemikhali zangoku zigquma i-TriGain™ ye-KSF/PFS ebomvu yephosphor kunye ne-JADEluxe ™ encinci ye-phosphor eluhlaza kwifilimu ye-phosphor, kwaye isebenzisana ne-Innolux ukwenza iiphaneli ze-MiniLED ze-backlight ze-LCD.I-Mini LED backlight display eboniswe ngeli xesha ineempawu zokungafani okuphezulu kunye nombala obanzi we-gamut, kwaye okwangoku kwimarike.
Ngokutsho kwedatha, iMichiza yangoku ineminyaka engaphezulu kwe-70 yophando kunye namava ophuhliso kwinkalo ye-phosphors ye-LED, iikhompawundi zomhlaba ezinqabileyo kunye nezinye iiphosphors kunye nokuhlanjululwa kwezinto ezintsha ze-luminescent.Xa kuthelekiswa ne-phosphor ye-KSF eqhelekileyo, i-TriGain ™ i-KSF/PFS iphosphor ebomvu inamandla okufunxa okuqinileyo kunye nokuthembeka okungcono, okunceda i-CRI 90 yeemveliso zokukhanyisa kunye ne-LED backlight displays ukuphumeza ubomvu obucebileyo kunye obucacileyo.
Iikhemikhali zangoku zikholelwa ukuba ifilimu entsha ye-phosphor edibanisa i-TriGain ™ KSF/PFS iphosphor ebomvu kunye ne-JADEluxe ™ i-phosphor eluhlaza emxinwa iya kudlala indima ebalulekileyo kwibala le-Micro LED displays.
