Kyulux is very proud of its HF TADF technology, that will enable efficient, cost-effective and durable OLEDs. Our greatest asset, however, is our employees, because a company is only as good as the people it’s made up of.
From time to time, this blog will give the stage to the bright and competent people who make Kyulux what it is.
Meet Tim Hirzel, Senior Researcher at Kyulux’s Boston office.
What does your position at Kyulux entail? My primary role at Kyulux is to empower our theoretical and experimental chemists with software and data management tools to accelerate their science and engineering practices. This consists of writing software, managing other software engineers, managing our compute cluster, and participating in scientific meetings to understand that process.
Where do you see the company in 5 years? Kyulux is armed with two exciting new technologies: Hyperfluorescence (HF) and our high throughput virtual screening (HTVS) tools. HF is our break-though technology, but we are also leveraging our HTVS tools to ensure that we deliver HF optimally, in the best possible device stack. In 5 years, I believe Kyulux can be a leader in OLEDs with the potential to impact other material markets as well. Our flexibility and accelerating technology makes us an excellent partner for other companies, and I see those partnerships as a key part of success in 5 years.
What is your favorite part of the day (at work…)? I doesn’t happen every day, but the best moment is after I’ve sat down to show a new tool to one of my colleagues, and they look up and say, “cool!” I love the challenge of building and making software tools but that smiling hand-off is the real reward. I’m lucky because my “customers” are my friends sitting next to me. I feel really lucky to have the job I do.
What do you think is the best local food? A common topic in the Boston office is how lucky we are in downtown Boston. There is an endless array of lunch options: chinatown, the food trucks, and countless eateries. It’s hard to pick one. I will say, if you come to Boston, try the Carnitas Burrito at Villa Mexico Cafe.
What was the latest book you read? I’ve been reading more graphic novels lately. I’ve got two young kids, and I’ll be honest, I fall asleep really quickly when I try to read! Graphic novels have managed to keep me up. I am really enjoying the Saga series from Brian K Vaughan. I’ve found graphic novels can push boundaries in terms of how wild and imaginative they are and I find that refreshing.
Next month Makuhari Messe outside of Tokyo will host Japan’s largest electronic exhibition and conference, CEATEC 2017. We will exhibit our Hyperfluorescence displays (and will include Wisechip’s HF PMOLED demonstration at our booth) during the event, and our CTO, Mr. Junji Adachi will give a presentation titled “Kyulux – Materializing the future of OLEDs with Hyperfluoresence, the optimum solution for OLED Display”. The presentation will be given twice on October 3rd and 5th, at 11:00 am.
CEATEC draws over 130,000 visitors each year and over 600 exhibitors. This year the event will include four areas: community, home & lifestyle, software and themed. Kyulux’s booth, #S10-73, will be in the themed area. The event takes place between October 3rd (Tuesday) and October 6th (Friday). We welcome you to our booth!
Wisechip demonstrated a yellow PMOLED device that featured a lifetime of over 30,000 hours (LT50) and an EQE of 14.6%, while still maintaining high color purity. Wisechip aims to release the first yellow and green HF PMOLEDs by the end of 2017, with red, blue and white displays planned for commercial launch in the near future.
During the TADF Workshop which was held in July 2017 in Kyushu, Japan, Wisechip’s VP of R&D Engineering Division, Dr. York Tsai, gave a presentation that detailed the Hyperfluorescence-PMOLED development effort that led to the successful demonstration and future introduction. It was a great presentation that clearly showed the advantages of our materials and their applications in Wisechip’s PMOLED displays.
Towards the end of July, the city of Fukuoka, where Kyushu University is located, hosted the 2nd international TADF Workshop. It was an excellent conference – with a larger turnout than expected – which we were proud to sponsor.
The event was a great combination of industrial lectures (from BOE, JDI, Dow Chemical, Kyulux and Wisechip) and in-depth academic and technical presentations from all over the world. It is clear that TADF emitters are exciting researchers and developers as these new materials are now set to enter the market in actual OLED displays.
The event also hosted a nice exhibition, focusing on manufacturing equipment. It was great to see JOLED’s beautiful printed 4K OLED monitor, Epson’s OLED-based AR glasses and of course Wisechip and Kyulux’s HF PMOLED demonstration.
The demonstrated display was a 0.96″ 128×64 monochrome (yellow) PMOLED. The EQE of the HF model is 14.5% compared to only 7.1% in the fluorescence display. We have now published the video above that very nicely shows the display in action and the whole demonstration – even though it is quite difficult to see just how brighter the HF display is. The image below shows this better.
Hyperfluorescence emitters enabled WiseChip to boost the efficiency by around 50% while still maintaining the color purity and a lifetime of over 30,000 hours (LT50).
Following this announcement, questions were raised as to the relevance of this technology for use in AMOLED displays, which represents a much larger market ($20 billion in 2017 and continue to grow fast compared to PMOLEDs’ $0.5 – 1 billion). Even though one should not rush to discount the PMOLEDs market, which is expected to stay relevant and grow (with the rise of wearables and introduction of flexible and transparent displays), it is clear that the AMOLED segment of the market remains dominant. In this article, we set out to clarify the difference between the two technologies and lift any doubt regarding the readiness of HF technology for AMOLED displays.
Kyulux, Inc., a world leader in next generation organic light emitting diode (OLED) technology, and WiseChip, a leading manufacturer of organic light emitting diode (OLED) products, today announced that the two companies plan to release a commercial product utilizing 4th generation HyperfluorescenceTM OLED light emission technology. This will be the first commercial product using this new generation of organic compounds in a commercial display product.
HyperfluorescenceTM is a 4th generation OLED technology that outperforms all previous generations of OLED emitters. The first generation of fluorescent compounds used for blue pixels in today’s cell phones and televisions are only 25% efficient and thus reduce the energy efficiency or battery life. The second generation green and red emitters used in cell phones and televisions are 100% efficient, but they use an expensive rare metal Iridium. This second generation of materials also suffers from an inferior color purity compared to the first generation. Fourth generation HyperfluorescenceTM allows for 100% quantum efficiency in a completely organic molecule without requiring the use of rare heavy metals to attain 100% efficiency. Further, HyperfluorescenceTM technology combines the superior color purity of gen 1 materials and the efficiency of gen 2 materials, allowing for increased battery life or increased brightness without sacrificing color purity.
WiseChip plans to begin offering commercial display products incorporating HyperfluorescenceTM by Q4 2017 and will become the first OLED display manufacturer to offer these 4th generation OLED displays for PMOLED applications. Through a highly collaborative engineering partnership, WiseChip and Kyulux have been able to rapidly increase the lifetime of TADF and HyperfluorescenceTM OLED devices even at the high current densities required for PMOLED applications. WiseChip and Kyulux will initially offer 4th generation monochromatic yellow and green displays, with red, blue and white displays planned for commercial launch in the near future.
The 2nd International TADF Workshop will take place on July 19-21 in Kyushu University, Fukuoka, Japan. The workshop is supported by Kyulux and aims to share the recent advances and future direction of TADF science and technologies.
While the event will be focused on academia oriented lectures, it will also include talks from industry leaders like the Dow Chemical Company, Japan Display, BOE Technology Group, Wisechip and of course Kyulux.
The world renowned OLED innovator and Kyulux’s co-founder Prof. Chihaya Adachi will deliver the opening remarks along with our CEO Dr. Christopher Savoie. Prof. Adachi will give a lecture titled “Diversity of TADF Technology in OLED and organic lasers” and our CTO Mr. Junji Adachi will give a lecture with the title “Materializing the future of OLEDs”.
The TADF workshop will also include a poster session and an exhibition where Kyulux will have a booth.
