Kyulux, established in Japan in 2015, develops next generation materials for OLED displays and lighting.
Based on exclusively-licensed technology from Kyushu University, Kyulux develops 4th-generation Hyperfluorescence TADF emitters that enable cost-effective, durable and efficient OLEDs that do not rely on rare metals. Kyulux is developing red, green, yellow and blue HF emitter systems.
In 2016 Kyulux raised $13.5 million from Samsung, LG, Japan Display, JOLED and more, and in 2019 the company announced it raised $31.8 million in its Series B round.
In October 2019 Wisechip launched the world’s first Hyperfluorescence TADF OLED display, a 2.7" yellow PMOLED that adopts Kyulux's HF emitter system. Kyulux started shipping commercial TADF materials for Wisechip in April 2020.

Kyulux explains how narrow-spectrum Hyperfluorescence emission is more efficient than PHOLED emission
Second-generation OLED phosphorescence emission features an internal quantum efficiency of almost 100% - which would normally mean you cannot get more efficient than that.
As Kyulux explains in a recent post, though, phosphorescent suffers from a wide emission spectrum. In order to achieve a good color gamut (for which as narrow-spectrum emission as possible is best) display makers have to filter out the "tail" of the emission. This results in reduced brightness and efficiency.
Kyulux says it is on track to commercialize green Hyperfluorescence materials in 2023, red and blue in 2024
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.
In recent years, we have seen accelerated OLED materials development, aided by software tools based on machine learning and Artificial Intelligence. This is an excellent development which contributes to the continued improvement in OLED efficiency, brightness and lifetime.
Kyulux's Kyumatic AI material discover system
The promise of these new technologies is the ability to screen millions of possible molecules and systems quickly and efficiently. Materials scientists can then take the most promising candidates and perform real synthesis and experiments to confirm the operation in actual OLED devices.
Hyperfluoresence emitter system developer Kyulux announced that its green material is getting close to commercialization. The company is now working closely with OLED makers, preparing for early adoption.
Kyulux says that its green emitter has not only met the required performance of OLED panel makers, in terms of efficiency, lifetime and driving voltage - but has actually surpassed the performance of green phosphorescent emitters in top emission devices. The green HF device achieves higher current efficiency, longer lifetime and offers a narrow emission spectrum and can thus enable better chromaticity.
During SID Display Week 2021, Kyulux detailed its latest TADF material performance. The red and green materials are "close to commercialization", and the company reports "excellent progress" with its blue emitter.
Using simulations, Kyulux shows how its Hyperfluorescence system is more efficient than a comparable phosphorescence emitter. While both emitters feature pretty much the same EQE, the narrow spectrum of the HF system which results in higher light intensity and can enable more efficient displays - by around 10%, according to Kyulux.
Kyulux raises $34 million in its latest funding round, receives basic HF TADF patent from Kyushu University
TADF materials developer Kyulux announced that it has finalized its Series-B-prime funding round, raising $34.3 million USD from several VCs and companies. Kyulux will be able to now accelerate its product development and drive for adoption of its materials in smartphone OLED displays.
Kyulux also announced plans to establish a mass production system for its materials, in cooperation with chemical companies.
TADF OLED materials developer Kyulux announced a new CEO and President, to replace the current CEO Mr. Junji Adachi. Mr. Nakano will become the company's new CEO starting February 11, while Junji has been appointed as Chief Strategy Office. This is a part of a wide management change at Kyulux that reflects the company's transition from material development to commercialization.
Mr. Nakano has an impressive industry background in addition to management positions, and since 2014 he was an executive officer and manager director of Japan's Innovation Network (INCJ).
TADF emitter developer Kyulux announced that has signed a joint-development agreement with Nippon Soda to develop new intermediates compounds for TADF emitters. The goal of this collaboration is to improve the performance and quality of Kyulux's TADF materials, and also dramatically improve the production efficiency of new compounds.
This agreement also markets Nippon Soda first entry into the OLED market. The company, founded in 1920, is highly environmentally conscious and has accumulated advanced organic material development capabilities and vast synthesis know-how, which will assist it in this new OLED project.
Due to the global COVID-19 pandemic, the 5th annual International TADF Workshop and the 3rd i3-opera Forum, a companion event aimed at industry researchers, will be held on December 7–8 by means of online live streaming.
In the Workshop, novel scientific concepts will be discussed, as well as the future direction of TADF-OLEDs, perovskite LEDs, radical-based LEDs, QD-based LEDs, novel materials-based LEDs and more. In the Forum, the scope will be extended even further, to include topics ranging from TADF frontier science to interdisciplinary technologies for future lifestyle.
Kyulux presented a new paper at SID Displayweek, that shows the latest progress of the company's Hyperfluorescence OLED emitter platform. You can see the latest performance chart below.
Hyperfluorescence combines TADF and fluorescence emitters, which enables high-efficiency (~100% IQE) emitters that feature long lifetimes and a very narrow emission spectrum. The company's yellow HF emitter is already commercialized, and now Kyulux says that its red and green materials are "close to commercialization". The company is also improving the color point and lifetime of its HF blue emitters.
