§ Private Profile · Fukuoka, Japan
OLED materials developer creating advanced TADF and Hyperfluorescence emitters for display and lighting manufacturers.
Kyulux develops advanced OLED emitter materials utilizing thermally activated delayed fluorescence (TADF) technology for more energy-efficient and brighter displays. Its technology aims for emitters four times as energy-efficient, generating four to five times the light intensity of current solutions, enabling longer-lasting batteries and sunlight-readable displays. Based in Fukuoka, Japan, with a Boston subsidiary, Kyulux raised $13.5 million in Series A funding, led by Samsung Venture Investment Corporation, including Samsung Display, LG Display, and Japan Display. It licenses core technology exclusively from Kyushu University and Harvard University. Established in 2015, Kyulux was founded by Chihaya Adachi, Junji Adachi, Akira Minakuchi, and Christopher J. Savoie, employing 91 individuals and operating R&D facilities in Fukuoka. The firm focuses on OLED display and lighting manufacturers, including major display companies evaluating their materials.
