Kyulux logo 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 hyperfluorescence TADF emitters that will enable cost-effective, durable and efficient OLEDs that do not rely on rare metals. Kyulux’s first aim is to develop commercial red, green and yellow hyperfluorescence emitter/host combinations, to replace the 2nd-Gen phosphorescent emitters currently used in OLED displays and lighting panels.

In March 2016 Kyulux raised $13.5 million from Samsung, LG, Japan Display, JOLED and more.

Kyulux signs JDA agreements with both SDC and LGD - aims to have commercial ready TADF/HF emitters ready by mid 2019

Kyulux announced that it has signed joint-development agreements (JDAs) with both LG Display and Samsung Display. The LGD agreement was signed in January 2018 while the SDC one was recently signed. Both agreements focus on deep blue Hyperfluoresence / TADF emitters.

Kyulux hopes that by collaborating with the two leading OLED producers, it will be able to accelerate its material development - and it aims to have commercial red, green and blue HF/TADF emitters ready by mid 2019.

An interview with Cynora's CMO Dr. Andreas Haldi - talking about TADF, lifetime, color points and more

German TADF developer Cynora presented its latest blue TADF material in May 2018 - with a CIEy of 0.14, EQE of 20% and a lifetime of 20 hours LT97 at 700 nits. Cynora expects to have blue material in the mass production by 2020.

Cynora's Chief Marketing Offer, Dr. Andreas Haldi was kind enough to answer a few questions we had regarding TADF emitters, the differences between next-generation emitter technologies, lifetime, color points and more.

Kyulux dramatically improves the performance of its blue HF emitter

Kyulux announced that it has developed a new blue Hyperfluoresence/TADF OLED emitter. Kyulux managed to extend the lifetime of the material and reached 100 hours at LT95 (@ 750 cd/m2) while maintaining a high EQE of 26% - 22% at 1,000 cd/m2. The emission wavelength is 470 nm.

Kyulux says that its blue Hyperfluorescence emitter is the world’s top performing material at the moment. Kyulux now aims to work together with OLED panel makers to improve the systems further by optimizing the device structure and the rest of the OLED stack in pilot production lines.

Wisechip and Kyulux to bring a flexible TADF/HF PMOLED to the market by the end of 2018

Kyulux and Wisechip unveiled a flexible PMOLED display that uses Kyulux’s Hyperfluoresence yellow emitter. Wisechip says that the power consumption of this display is almost half of Wisechip's regular fluorescent yellow PMOLED.

The first flexible HF PMOLED is a 1.71″ 256x64 display, that is now ready to be produced (Wisechip says this will enter mass production before the end of 2018). Wisechip originally aimed to introduce its first glass-based HF yellow emitter PMOLED by the end of 2017, but it seems they decided to jump straight to a flexible panel.

Nagase invests $4.6 million in TADF developer Kyulux

Japan-based chemical producer Nagase announced that it invested ¥500 million Yen ($4.6 million USD) in Hyperfluoresence TADF materials developer Kyulux. Nagase is currently offering materials for LCD producers, so this is likely to be a strategic investment for the company.

Kyulux’s first aim is to develop commercial red, green and yellow hyperfluorescence emitter/host combinations, to replace the 2nd-Gen phosphorescent emitters currently used in OLED displays and lighting panels. In 2017 Kyulux announced a collaboration with PMOLED maker WiseChip to bring Hyperfluoresence TADF emitter based displays to the market by the year's end.

Wisechip explains the development effort behind its HF-TADF PMOLED

Last month PMOLED maker WiseChip demonstrated a Hyperfluoresence TADF PMOLED display in a trade show in Japan, following a collaboration with HF TADF developer Kyulux. Wisechip says it will bring its first HF-TADF PMOLEDs to the market by the end of 2017.

Kyulux today uploaded Wisechip's presentation from the TADF workshop. In this lecture Wisechip’s VP of R&D Engineering Division, Dr. York Tsai, gave a presentation that detailed the Hyperfluorescence-PMOLED development effort and the performance boost enabled by the new material.

Wisechip to commercialize Hyperfluorescence TADF PMOLEDs by year's end

Hyperfluoresence TADF materials developer Kyulux announced a collaboration with PMOLED maker WiseChip to bring Hyperfluoresence TADF emitter based displays to the market by year's end. Wisechip demonstrated an HF TADF display at the TADF Workshop last week in Fukuoka, Japan.

The PMOLED display shown by Wisechip was a 0.96" monochrome yellow 128x64 one. The demonstration showed how much brighter (or more efficient) the Hyperfluoresence based display is compared to Wisechip's current fluoresent-based displays. The power saving is almost 50%.

OLED-Info at the TADF Workshop in Kyushu University next week

Next week Kyushu University (in Fukuoka, Japan) will be hosting the 2nd International TADF Workshop. The event aims to share the recent advances and future direction of TADF science and technologies.

The OLED-Info team will attend this exciting workshop. The focus will be on academia oriented lectures, but the event will also include talks from the Dow Chemical Company, Japan Display, BOE Technology Group, Wisechip and TADF developer Kyulux who's sponsoring the event. The workshop will also include a small exhibition and poster sessions.

Kyulux recruits Kateeva's Dr. Chris Brown as VP of products

Dr. Chris Brown photoHyperfluoresence TADF materials developer Kyulux announced that Dr. Chris Brown will join the company as VP of Products. Dr. Brown will lead Kyulux's product development and delivery efforts ahead of the company's anticipated first commercial deployments of TADF and Hyperfluorescence materials in the coming year.

Dr. Brown joins Kyulux from OLED inkjet equipment maker Kateeva, where he was Vice President of Process Engineering. Dr. Brown has been granted 31 US patents and has 34 publications.

Nanoco and Kyulux to co-develop hybrid OLED / QLED display technology

Hyperfluoresence and TADF OLED emitter developer Kyulux and quantum-dot developer Nanoco announced that the two companies will co-develop a future-generation hybrid OLED / QLED display technology that combines Kyulux's hyperflourescent emitters and Nanoco's heavy metal free quantum dots (CDQDs).
