Impressions from the 2017 TADF Workshop

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.


Video shows Wisechip’s Hyperfluoresence PMOLED demonstration

During the 2nd international TADF Workshop, Wisechip demonstrated the world’s first Hyperfluoresence based OLED display, a yellow monochrome PMOLED that draws half the power compared to Wisechip’s current fluorescence PMOLED displays.

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.


Is Hyperfluorescence ready for AMOLED adoption?

Two weeks ago we announced a collaboration with WiseChip Semiconductor to use Hyperfluorescence emitters in WiseChip’s PMOLED displays. In early July, Wisechip demonstrated a working yellow monochrome prototype – with commercial production expected by the end of 2017 for both yellow and green displays.

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 and WiseChip Collaborating to Commercialize TADF and Hyperfluorescence OLED Product

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.


Join us next week at the TADF workshop in Kyushu University

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.

Come meet us at our exhibition booth and conference! For more information click here (registration for the event is free of charge).
