Almost a decade has passed since the first demonstration of thermally activated delayed fluorescence (TADF) in an OLED at Kyushu University in 2009, and these past ten years have seen rapid and remarkable advances in this scientific field.
To mark the 10-year anniversary of TADF, we are delighted to announce the organization of the 4th International TADF Workshop in Fukuoka, in collaboration with Opera and i3-Opera, to share the latest advances and future direction of TADF science and technologies. The workshop will cover a diverse range of topics in the areas of TADF and excitonic materials, physics, and devices.
Kyulux, Inc., a global leader of TADF and Hyperfluorescence™ developer, has been engaged in a joint development focusing on blue TADF and Hyperfluorescence™ with LG Display Co., Ltd., from January, 2018.
In addition to LG Display, Kyulux has now executed a Joint Development Agreement (JDA) focusing on Deep Blue with Samsung Display Corporation. Both of two giant display panel makers in OLED, LG Display and Samsung Display have now selected Kyulux as a blue TADF and Hyperfluorescence™ joint development partner.
Kyulux demonstrated a white OLED display that uses an orange TADF emitter combined with a blue fluorescence emitter. The novel display was developed in collaboration with the Fukuoka i3 center for Organic Photonics and Electronics Research (i3-OPERA) for demonstration at the 3rd International TADF Workshop in late July.
The display was designed by i3-OPERA and Kyulux provided the orange TADF emitter. This demonstration successfully showed the commercial viability of a TADF-based white OLED display. Kyulux and the i3-OPERA will continue the collaboration to enhance the performance and the lifetime of this display. The next step in this project is use only TADF emitters including a blue TADF emitter.
Last week at the SID DisplayWeek in Los Angeles, CA, Kyulux demonstrated Wisechip’s latest flexible PMOLED display – that uses Kyulux’s Hyperfluorescence yellow emitter. The power consumption of this display, compared to Wisechip’s fluorescent yellow, is almost half!
The Wisechip flexible display is 42.22 mm x 10.54 mm in size (1.71″ diagonal), with a resolution of 256×64 pixels. This display is now ready to be produced and Wisechip believes it will enter mass production before the end of 2018. If so this will be the world’s first HF (TADF) powered device!
The 3rd International TADF Workshop will take place on July 19-20th, 2018, in Fukuoka, Japan. This scientific event will discuss the latest in TADF materials, device architectures, upconversion mechanisms and TADF applications. Other topics will include singlet fission and perovskite emitters.
The event is organized by Kyushu University, i3-OPERA and Kyulux. The TADF Workshop will be preceded by the i3-OPERA Forum, which focuses on industry-oriented OLED technologies.
