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.
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.
Attending the TADF Workshop is free of charge (but there is a charge to attend the Conference Banquet). For more information and to register, click here!
The first-generation OLED emitter systems, based on fluorescence, lack efficiency as only about 25% of the energy is converted into light. More advanced systems, based on phosphorescence (PHOLED), TADF and our own Hyperfluorescence (HF) technology all manage to convert almost 100% of the energy into light, and so it is mistakenly perceived that such systems all offer the same efficiency.
The reality, however, is that Kyulux’s HF systems offer an inherent advantage that enables it to provide the most efficient OLED emitters of all four generations. As seen in the graph above, HF emitters are the only emitters that offer both a narrow spectrum and high-efficiency. HF can be thought of as a combination of the high efficiency of TADF and the narrow spectrum of Fluorescence.
