Iyo Chinese Academy yeScience yakagadzira imwe-chikamu chinodziya chena LED
Munguva pfupi yapfuura, Yang Bin, anosanganisa muongorori weiyo yakaoma molecular system reaction dynamics tsvakiridzo boka reDalian Institute of Chemical Physics, akabatana naLiu Feng, muongorori weShandong University, kugadzira rudzi rutsva rwekaviri perovskite zvinhu zvine yakakwira-inoshanda chena mwenje emission, uye akagadzirira chimwe-chikamu chinobva pane ichi chinyorwa.Anodziya chena mwenje emitting diodes (LED).
Mwenje yemagetsi inoita 15% yemagetsi epasi rose ekushandiswa kwemagetsi uye inoburitsa 5% yepasi rose greenhouse magasi.Kugamuchirwa kwehunyanzvi hwekuvhenekesa uye kudhura kwakaderera kunogona kuderedza simba uye matambudziko ezvakatipoteredza uye kubatsira kuzadzisa chinangwa che "double carbon".Yakanakiraflexible led screen.Parizvino, mazhinji machena emwenje e LED tekinoroji anonyanya kuvimba neblue mwenje ma LEDs kuti inakidze yakawanda-chikamu chefluorescent superposition kuti ibudise mwenje chena, saka matambudziko akadai sekushata kwemavara kupa, kuderera kwechiedza, kukuvadza kwakanyanya kweblue mwenje, uye discontinuous chena mwenje spectrum. zviri nyore kuitika.Kuvandudzwa kwepamusoro-soro-imwe-chikamu chichena chechiedza chemagetsi chinoonekwa sechinhu chikuru chekugadzirisa matambudziko ari pamusoro.
Vatsvagiri vakawana kuti lead-isina simbi halide kaviri perovskite zvinhu zvinogona kugadzirwa mune yakaderera-tembiricha mhinduro nzira ine yakaderera mutengo wekugadzira.Pamusoro pezvo, nekuda kwekuvharirwa kwechimiro chayo uye iyo yakasimba yemagetsi-phonon coupling effect, kaviri perovskite zvinhu zvine yakasarudzika self-trapped excitonic properties (STE), uye yavo composite luminescence inoratidza guru Stokes shift uye Broadband chiedza emission, nokudaro vachiratidza. maitiro ekubuda kwechiedza chichena.
Kuti ukurudzire kudzokororwa kweradiative, vaongorori vakawedzera kutora Sb3+ doping zano rekuwedzera quantum kunyatsoshanda kwechiedza chichena kubva pa5% kusvika kupfuura 90%.Nekuda kweiyo yakakwira optoelectronic kuita uye yakanakisa mhinduro machinability yeyakagadzirirwa yakaderera-dimensional kaviri perovskite zvinhu, imwe-chikamu chinodziya chena LED yakavakirwa pane ino chinyorwa inogona kugadzirwa nenzira yakapusa mhinduro, nekudaro, basa iri riri kuvimbisa chizvarwa chinotevera. midziyo yekuvhenekesa.Iyo yakagadzirwa inopa mazano matsva.
Apple yekupeta skrini patent kuratidzwa, screen creases inogona kunge ichizvigadzirisa
Runyerekupe rwekuti Apple irikuda kupinda mumusika wemuchina wekupeta rakaramba richikwezva kutarisisa kwakanyanya kubva kunze kwenyika mumakore achangopfuura, uye Samsung, ine nzvimbo yekupeta nharembozha, usazeze kuifuratira.Pakutanga kwaNovember, Samsung yakafungidzira pamusangano wevatengesi kuti inotarisirwa kunge ichangotanga muna 2024, uye panogona kuve nemukana wekuona chigadzirwa chitsva cheApple chine "kupeta" dhizaini, asi yekutanga kupeta chigadzirwa Kwete. foni, asi piritsi kana laptop.
Zvinoenderana neshumo ichangoburwa kubva kune vekunze vezvenhau Patently Apple, Apple ichangobva kuisa gwaro rekunyorera kuUS Patent uye Trademark Hofisi, zvichiratidza kuti iyo screen crease yekuzvirapa yekuratidzira tekinoroji yakagadziridzwa kwemakore mazhinji inotarisirwa kuiswa pakupeta. -zvine chokuita nemidziyo.
Kunyangwe zviri mukati meiyo patent tekinoroji isingataure zvakananga kuti yakazvarirwa kupeta maPhones, inongoratidza kuti inogona kuiswa kune iPhones, mahwendefa kana MacBooks.Nekudaro, nekuratidzwa kweiyi nyowani tekinoroji patent, vazhinji vekunze vanoidudzira segadziriro yepamberi yekuti iPhone yekupeta ichatangwa mune ramangwana.
Tichitarisa tekinoroji iripo panguva ino, zvakaoma kudzivirira kupeta nharembozha ine concave kupeta dhizaini kwenguva yakareba yekushandiswa.
Kuti uvandudze ruzivo rwemushandisi uye nekunakisa kufunga kunokonzerwa necreases inokonzerwa nekupeta michina, tekinoroji nhema yakagadziridzwa neApple pachayo inoda kushandiswa kwehunyanzvi hwekuputira nemaconductor akasarudzika uye zvinhu zvekuzviporesa, izvo zvinogona kushandiswa kuvhara kunze kwekunze. yechiratidzo chemudziyo.Apo ikozvino inopfuura nepakati Panguva imwecheteyo, kuburikidza nekushandiswa kwechiedza kana kupisa kwekushisa kubva kune imwe nzvimbo yekunze, kuzvidzora kwekuzvirapa kwekukurumidza creases kunokurudzirwa.
Izvo hazvisati zvazivikanwa kuti iyi yakakosha tekinoroji tekinoroji ichaiswa riini kumidziyo yeApple munguva pfupi yapfuura mushure mekunge yawana ongororo uye chitupa mune ramangwana.Nekudaro, tichitarisa kubva kurondedzero yetekinoroji ine patent, tekinoroji inosanganisira huwandu hwakasiyana hwemazinga uye hwakanyanya kuoma.Yakanakiratransparent led skrini.Uye zvakare, iyi patent yakanyorwa neApple sechigadzirwa chitsva tekinoroji yeboka rakakosha reprojekiti, iyo inoratidza kuti Apple inokoshesa zvakanyanya kwairi.
Mini / Micro LED nyowani tekinoroji
Zvinonzwisisika kuti iyo 2022 Phosphors & Quantum Dots Indasitiri Forum yakaitirwa muSan Francisco, USA mukupera kwemwedzi wapfuura.Munguva iyi, iyo yakakosha yemidziyo kambani yeChazvino, inogadzira mwenje we LED, yakatanga chinhu chitsva chekuratidzira - phosphor firimu, uye yakaratidza Mini LED backlight kuratidza ine firimu nyowani phosphor.
Iyezvino Kemikari inoputira Yazvino TriGain™ KSF/PFS tsvuku phosphor uye itsva JADEluxe ™ nhete-bhendi yakasvibira phosphor mufirimu rephosphor, uye inobatira pamwe neInnolux kugadzira MiniLED LCD backlight mapaneru.Iyo Mini LED backlight inoratidzwa panguva ino ine hunhu hwekusiyanisa uye yakakura color gamut, uye parizvino iri pamusika.
Zvinoenderana nedata, Current Chemicals ine makore anopfuura makumi manomwe ekutsvagisa uye ruzivo rwebudiriro mumunda we LED phosphors, isingawanzo pasi pasi makomisheni uye mamwe maphosphors uye yakakwirira-kuchena luminescent zvinhu hunyanzvi.Kana ichienzaniswa neyakajairwa KSF phosphor, yakatarisana nayo TriGain™ KSF/PFS tsvuku phosphor ine simba rekunyudza uye kuvimbika kuri nani, iyo inobatsira CRI 90 zvigadzirwa zvekuvhenekesa uye LED backlight inoratidzira kuwana yakapfuma uye yakajeka tsvuku.
Current Chemicals anotenda kuti iyo nyowani phosphor firimu rinosanganisa TriGain ™ KSF/PFS tsvuku phosphor uye JADEluxe ™ nhete-bhendi yegirini phosphor ichaita basa rakakosha mumunda weMini/Micro LED kuratidza.
