Zida Zosinthika za OLED: Kusintha Mafakitale Angapo Ndi Mapulogalamu Atsopano

Ukadaulo wa OLED (Organic Light Emitting Diode), womwe umadziwika kwambiri kuti umagwiritsa ntchito mafoni a m'manja, ma TV apamwamba kwambiri, mapiritsi, ndi zowonetsera zamagalimoto, tsopano ukutsimikizira kufunika kwake kuposa momwe amachitira kale. Pazaka ziwiri zapitazi, OLED yapita patsogolo kwambiri pakuwunikira mwanzeru, kuphatikiza nyali zamagalimoto zanzeru za OLED ndi nyali zoteteza maso za OLED, kuwonetsa kuthekera kwake kwakukulu pakuwunikira. Kupitilira zowonetsera ndi kuyatsa, OLED ikufufuzidwa kwambiri m'magawo monga photomedicine, zida zovala, ndi nsalu zowala.

Chimodzi mwazinthu zochititsa chidwi kwambiri ndikugwiritsa ntchito OLED pamapangidwe agalimoto. Zapita masiku a nyali zotukwana, zothwanima mchira. Magalimoto amakono tsopano ali ndi "zowunikira zamchira" zomwe zimatulutsa mawonekedwe ofewa, osinthika makonda, mitundu, ngakhale mameseji. Magetsi amchira opangidwa ndi OLEDwa amakhala ngati ma board osintha, kupititsa patsogolo chitetezo komanso makonda kwa madalaivala.

Wopanga wamkulu waku China wa OLED wakhala patsogolo pazatsopanozi. Wapampando a Hu Yonglan adagawana nawo poyankhulana ndi *China Electronics News* kuti nyali zawo za OLED zamchira za digito zatengedwa ndi mitundu ingapo yamagalimoto. "Kuwala kwa mchira uku sikumangowonjezera chitetezo pakuyendetsa usiku komanso kumapereka zosankha zaumwini kwa eni magalimoto," adatero Hu. Pazaka ziwiri zapitazi, msika wamagetsi amchira okhala ndi OLED wakula pafupifupi 30%. Chifukwa chotsika mtengo komanso kupita patsogolo kwaukadaulo wowonetsera, OLED ikuyembekezeka kupereka mayankho osiyanasiyana komanso makonda kwa ogula.

Mosiyana ndi malingaliro akuti OLED ndi okwera mtengo, akatswiri amakampani amayerekeza kuti makina owunikira a OLED amatha kuchepetsa ndalama zonse ndi 20% mpaka 30% poyerekeza ndi njira zachikhalidwe. Kuphatikiza apo, zodzikongoletsera za OLED zimachotsa kufunikira kowunikiranso, zomwe zimapangitsa kuti pakhale kutsika kwamagetsi ndikusunga kuwala kwakukulu. Kupitilira ntchito zamagalimoto, OLED imakhala ndi kuthekera kwakukulu pakuwunikira kwanyumba mwanzeru komanso kuwunikira kwapagulu.

Hu Yonglan adawunikiranso ntchito yolonjeza ya OLED mu photomedicine. Kuwala kwakhala kukugwiritsidwa ntchito pochiza matenda osiyanasiyana, monga ziphuphu zakumaso zokhala ndi mphamvu zambiri zabuluu (400nm-420nm), kutsitsimutsa khungu ndi chikasu (570nm) kapena kuwala kofiyira (630nm), komanso chithandizo cha kunenepa kwambiri ndi kuwala kwa 635nm LED. Kutha kwa OLED kutulutsa mafunde enieni, kuphatikiza kuwala kwapafupi ndi infrared ndi buluu wakuya, kumatsegula mwayi watsopano mu photomedicine. Mosiyana ndi magwero achikhalidwe a LED kapena laser, OLED imapereka kuwala kofewa, kofananira, kupangitsa kuti ikhale yabwino pazida zamankhwala zotha kuvala komanso zosinthika.

Everbright Technology yapanga gwero loyatsa lofiira la OLED lokhala ndi kutalika kwa 630nm, lopangidwa kuti lithandizire kuchiritsa mabala ndikuchiza kutupa. Pambuyo pomaliza kuyezetsa koyambirira ndi kutsimikizira, mankhwalawa akuyembekezeka kulowa mumsika wamankhwala pofika chaka cha 2025. Hu adawonetsa chiyembekezo chokhudza tsogolo la OLED mu photomedicine, akuwona zida za OLED zovala zosamalira khungu tsiku ndi tsiku, monga kukula kwa tsitsi, kuchiritsa mabala, ndi kuchepetsa kutupa. Kuthekera kwa OLED kugwira ntchito pa kutentha pafupi ndi kutentha kwa thupi la munthu kumawonjezera kukwanira kwake pakugwiritsa ntchito anthu omwe ali pafupi, kusinthira momwe timalumikizirana ndi magwero a kuwala.

Pankhani yaukadaulo wovala ndi nsalu, OLED ikupanganso mafunde. Ofufuza ku Fudan University apanga nsalu yapamwamba kwambiri yamagetsi yomwe imagwira ntchito ngati chiwonetsero. Mwa kuluka ulusi wonyezimira wokhala ndi ulusi wonyezimira wonyezimira, anapanga mayunitsi a ma electroluminescent a micrometer-scale. Nsalu yatsopanoyi imatha kuwonetsa zambiri pazovala, kupereka mwayi watsopano wamasewera a siteji, ziwonetsero, ndi zojambulajambula. Kusinthasintha kwa OLED kumapangitsa kuti ikhale yophatikizika m'mitundu yosiyanasiyana, kuyambira zovala zanzeru ndi zodzikongoletsera mpaka makatani, makatani, ndi mipando, kuphatikiza magwiridwe antchito ndi kukongola.

Kupita patsogolo kwaposachedwa kwapangitsa ulusi wamagetsi wa OLED kuti uzitha kutsuka komanso wokhazikika, ndikusunga bwino kwambiri ngakhale nyengo itakhala yovuta. Izi zimatsegula mwayi wogwiritsa ntchito zazikulu, monga zikwangwani zoyendetsedwa ndi OLED kapena makatani m'malo opezeka anthu ambiri monga masitolo akuluakulu ndi ma eyapoti. Zowonetsera zopepuka, zosinthikazi zimatha kukopa chidwi, kutumiza mauthenga amtundu, ndikuyika kapena kuchotsedwa mosavuta, kuzipanga kukhala zabwino pazotsatsa kwakanthawi kochepa komanso ziwonetsero zazitali.

Pomwe ukadaulo wa OLED ukupitilirabe komanso mtengo ukucheperachepera, titha kuyembekezera kuwona zinthu zambiri zoyendetsedwa ndi OLED zikulemeretsa moyo wathu watsiku ndi tsiku. Kuchokera pa kuyatsa magalimoto ndi chithandizo chamankhwala kupita kuukadaulo wovala komanso kawonekedwe kaluso, OLED ikutsegulira njira yamtsogolo mwanzeru, yopangira zinthu zambiri, komanso yolumikizana.
