Researchers from Kyushu University (led by Chihaya Adachi) are developing highly efficient blue OLED TADF (Thermally Activated Delayed Fluorescence, also called hyper-fluorescence) emitters.
Kyushu University now spun-off a new company, called Kyulux, backed by the University's QB Fund and the Japan Society for the Promotion of Science, to commercialize the TADF emitters. Kyulux raised ¥1.5 billion (around $13 million USD) and hopes to have their emitters ready by 2018.
You can read more about Kyushu's TADF emitters here, and we also host an OLED Auditorium presentation from Prof. Adachi here.
Kyushu University isn't the only TADF emitter developer. German Cynora is developing efficient blue TADF OLED emitters, and in March 2015 the European Commission launched a new project called Phebe that aims to develop and commercialize TADF emitters.
