Ngomhlaka-21 Januwari, i-NHK Science and Technology Research Laboratories (ebizwa ngokuthi i-NHK STRL), ngokubambisana neChiba University kanye neKyoto University, yamemezela ukuthuthukiswa kwedivayisi yokuqala yokubonisa i-OLED emhlabeni enemisebenzi emibili yokukhipha ukukhanya kanye nokukhiqizwa kwamandla elanga, ngemuva kokuthola ngempumelelo ukukhishwa kokukhanya okuluhlaza okwesibhakabhaka. Lobu buchwepheshe buhloselwe ukusetshenziswa ezindaweni ezithinteke yinhlekelele, okuvumela isibonisi ukuthi sikhiphe ukukhanya ngokuzimela ngaphandle kokunikezwa kwamandla angaphandle.

Ngaphambilini, ukukhishwa kokukhanya kwe-semiconductor ye-organic kanye nokukhiqizwa kwamandla elanga kwakusebenza ngezimiso eziphikisanayo: okokuqala kudinga amandla kagesi ukuze kukhiqizwe ukukhanya, kanti okwesibili kukhiqiza ugesi ngokumunca ukukhanya, okwenza kube nzima ukuhlanganisa imisebenzi yomibili kudivayisi eyodwa. Ngenxa yalokhu kuphumelela, ithimba locwaningo lamukele izinto ze-MR-TADF—ezinokusebenza kahle okuphezulu kokukhanya kanye nezakhiwo eziqinile zokumunca ukukhanya—futhi ngokulawula ngokunembile amandla ngaphakathi kwedivayisi, bakha ngempumelelo idivayisi ye-OLED engashintsha phakathi kwezindlela zokukhipha ukukhanya kanye nezindlela zokukhiqiza amandla elanga.

Njengoba kuphawuliwe, izinto ze-MR-TADF zimelela ukuthuthuka okuthuthukile kobuchwepheshe be-OLED besizukulwane sesithathu. Zibonakala ngekhono lokukhipha ukukhanya okune-spectrum encane (ngobubanzi obugcwele obungaphansi kwesigamu sobukhulu obungaphansi kwama-40nm), okuletha ubumsulwa bombala obuphezulu kanye nokusebenza kahle okuphezulu. Ithimba locwaningo liphumelele ekutholeni ukukhishwa kokukhanya ngemibala emithathu eyinhloko ebomvu, eluhlaza okwesibhakabhaka kanye nohlaza okwesibhakabhaka; phakathi kwalokhu, ukusebenza kahle kwe-quantum kwamadivayisi akhipha ukukhanya okuluhlaza okwesibhakabhaka nokubomvu kudlula u-8.5%, kokubili ukusebenza kahle okukhanyayo kanye nokusebenza kahle kokukhiqiza amandla kufinyelela ezingeni eliphakeme kakhulu emhlabeni.

Ngaphezu kokusebenzisa ubuchwepheshe bokubonisa be-OLED obuthuthukiswe ngokuzimela ngaphakathi, i-NHK STRL yenze ucwaningo kanye nokuthuthukiswa kwezinto ze-MR-TADF ne-Kyoto University, kanye nocwaningo oluthuthukisiwe lokuhlaziya ngezimiso zokusebenza kwezinto ngokubambisana ne-Chiba University.

I-NHK STRL ithe izogxila ekuthuthukiseni ukusebenza kahle okukhanyayo, ukusebenza kahle kokukhiqiza ugesi kanye nokuqina kwedivayisi, ngenhloso yokuthengisa amadivayisi okubonisa asebenzisa amandla amancane. Esikhathini esizayo, lobu buchwepheshe bungasetshenziswa nasezindaweni ezidinga ukukhiqizwa kombala okunembile, njenge-augmented reality (AR) kanye ne-virtual reality (VR).
