Kyulux’s red and green materials are now close to commercialization with lifetimes of over 37,000 hours (LT95), and 20,000 hours (LT95) respectively. Also the blue TADF has shown excellent progress with a lifetime of 280 hours (LT95) for a bottom emission.
Kyulux also released information on simulations that showed how a
Hyperfluorescence™ (HF) system is more efficient than a phosphorescence emitter system.

Hyperfluorescence™ (HF) emits a very narrow spectrum. Its full width half maximum (FWHM) is 34nm in green-HF in a bottom emission (BE) device. In a top emission (TE) device, this narrow spectrum of HF enables higher efficiency and light intensity than a phosphorescence emitter system. HF system will feature an EQE improvement of around 10% over a phosphorescence one, while the peak EL intensity is over 60% higher. These results showed that HF would be the optimum emitting technology for smartphone which adopted a TE device structure.
