We are thrilled to share that Professor Chihaya Adachi, Co-founder and Scientific Advisor of Kyulux, has been awarded the Jan Rajchman Prize, one of the most respected honors in display technology. The award recognizes his groundbreaking contributions to TADF (Thermally Activated Delayed Fluorescence) molecules, which have opened a new chapter in high-efficiency OLED displays.

 

Professor Adachi has led OLED research for over three decades. In the early 2000s, he shifted his focus to the then-unknown TADF phenomenon. Through innovative quantum chemical calculations, his team succeeded in developing materials with 100% internal quantum efficiency―without relying on rare metals. These donor-acceptor based aromatic compounds marked a major leap forward, establishing TADF as the third generation of OLED emitters.

In 2015, building on this breakthrough, Professor Adachi co-founded Kyulux to accelerate the development and commercialization of TADF-based OLED materials. His scientific leadership continues to inspire innovation at Kyulux today.

He also leads the Center for Organic Photonics and Electronics Research (OPERA) at Kyushu University, a global hub of excellence in organic electronics. His research has provided deep insights into the charge-transfer states essential for improving device performance and engineering.

Professor Adachi holds a PhD in materials science from Kyushu University and has authored over 750 scientific papers, 37 books, and 321 patents. He has received numerous awards, including the Medal with Purple Ribbon from the Japanese government in 2023.

We at Kyulux sincerely congratulate Professor Adachi on this outstanding recognition. His vision and dedication are key to driving the future of OLED innovation worldwide.
