Kyulux gave a very upbeat presentation at SID Displayweek, during which it updated on its latest material specification and its commercialization plans.

Kyulux managed to increase the lifetime of its Hyperfluorescence emitter systems (which features an IQE of 100% and a narrow emission spectrum) quite dramatically in the past year – its green material now offers a lifetime of 59,000 hours (LT95@1000 nits, top emission), while the red material is at 20,000 hours. The blue material has also increase from280 hours to 450 hours in the past year.

Kyulux has also unveiled its commercialization plans. For its green and red materials, the company is already working with customers to optimize the device stack, and pilot testing should begin in Q3 2022 (for the green material). Kyulux expects to see its green material enter mass production (and adoption) in the second half of 2023, for smartphone AMOLED displays. The red material will follow suit with production in early 2024.

Kyulux’s blue material is also advancing, and the company says it will have a commercial-grade material by the end of 2022. Commercialization should begin before the end of 2024. This is a similar timeline to what Universal Display announced earlier this year, this is going to be very interesting to watch.



Kyulux's 4th-Gen Hyperfluorescence materials offer excellent performance both in terms of efficiency and emission spectrum, and do not contain any heavy metals, and so Kyulux believes that the industry will adopt its materials over currently-used phosphorescent materials.
