Pa Januwale 21, NHK Science and Technology Research Laboratories (yomwe tsopano ikutchedwa NHK STRL), mogwirizana ndi Chiba University ndi Kyoto University, adalengeza za chitukuko cha chipangizo choyamba chowonetsera cha OLED padziko lonse lapansi chomwe chili ndi ntchito ziwiri monga kutulutsa kuwala ndi kupanga mphamvu ya dzuwa, atakwanitsa kutulutsa kuwala kwabuluu bwino. Ukadaulo uwu wapangidwira kugwiritsidwa ntchito m'malo omwe akhudzidwa ndi masoka, zomwe zimathandiza kuti chiwonetserocho chizitulutsa kuwala chokha popanda magetsi akunja.

Kale, kutulutsa kwa kuwala kwa semiconductor ndi kupanga mphamvu ya dzuwa kunkagwira ntchito motsatira mfundo zosiyana: choyamba chimafuna mphamvu yamagetsi kuti chipange kuwala, pomwe chachiwiri chimapanga magetsi poyamwa kuwala, zomwe zimapangitsa kuti zikhale zovuta kuphatikiza ntchito zonse ziwiri mu chipangizo chimodzi. Pachitukuko ichi, gulu lofufuza lidagwiritsa ntchito zipangizo za MR-TADF—zomwe zili ndi mphamvu zambiri zowunikira komanso mphamvu zoyamwa kuwala—ndipo mwa kuwongolera bwino mphamvu mkati mwa chipangizocho, adapanga bwino chipangizo cha OLED chomwe chingasinthe pakati pa njira zotulutsa kuwala ndi zopangira mphamvu ya dzuwa.

Monga taonera, zipangizo za MR-TADF zikuyimira kusintha kwapamwamba kwa ukadaulo wa OLED wa m'badwo wachitatu. Zimadziwika ndi kuthekera kotulutsa kuwala kopapatiza (kokhala ndi m'lifupi wonse pa theka la kutalika kochepera 40nm), kupereka kuyera kwamitundu yambiri komanso magwiridwe antchito apamwamba. Gulu lofufuza lakwanitsa kutulutsa kuwala bwino mumitundu itatu yayikulu ya ofiira, obiriwira ndi abuluu; pakati pa izi, mphamvu yakunja ya zida zobiriwira ndi zofiira zotulutsa kuwala zimaposa 8.5%, ndipo mphamvu zonse zowala komanso mphamvu zopangira mphamvu zimafika pamlingo wapamwamba kwambiri padziko lonse lapansi.

Kuwonjezera pa kugwiritsa ntchito ukadaulo wa OLED wopangidwa payekha, NHK STRL yachita kafukufuku ndi chitukuko cha zipangizo za MR-TADF ndi Kyoto University, komanso kafukufuku wapamwamba wokhudza mfundo zogwirira ntchito za zipangizozi mogwirizana ndi Chiba University.

NHK STRL inanena kuti idzayang'ana kwambiri pakuwonjezera mphamvu yowala, mphamvu yopangira magetsi komanso kulimba kwa chipangizocho, ndi cholinga chogulitsa zida zowonetsera zomwe sizimagwiritsa ntchito mphamvu zambiri. M'tsogolomu, ukadaulo uwu ungagwiritsidwenso ntchito m'magawo omwe amafunikira kubwerezanso mitundu molondola, monga augmented reality (AR) ndi virtual reality (VR).
