Kyulux develops hyperfluorescenceTM OLEDs, which combine TADF and fluorescence emitters to enable highly efficient emission (100% IQE), low cost and high color purity. HyperfluorescenceTM was invented at Kyushu University by Dr. Chihaya Adachi and the technology is exclusively licensed to Kyulux.
Kyulux’s first aim is to develop commercial red, green and yellow HyperfluorescenceTM emitter/host combinations, to replace the 2nd-Gen phosphorescent emitters currently used in OLED displays and lighting panels.
The drive towards high color gamut displays requires emitters with narrow spectrum. While 1st-gen fluorescence emitters do feature such a narrow spectrum, they severely lack in efficiency. The currently widespread high-efficiency 2nd-gen heavy-metal based phosphorescence emitters suffer from a wide spectrum and high costs.
For the first time ever, HyperfluorescenceTM emitters manage to bring together high efficiency and a narrow spectrum and are thus poised to become the ultimate emitter system.
