Kyulux chosen by Samsung Display and LG Display as Blue TADF and Hyperfluorescence™ developer

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 and i3-OPERA collaborate to demonstrate a TADF-Fluorescence white OLED display at the 3rd International TADF Workshop

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.

Kyulux and Wisechip unveiled a flexible HF PMOLED display

Last week at the SID DisplayWeek in Los Angeles, CA, Kyulux demonstrated Wisechip’s latest flexible PMOLED display – that uses Kyulux’s Hyperfluoresence 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!

Kyulux welcomes you to the 2018 International TADF Workshop

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 narrow spectrum of Hyperfluorescence enables better efficiencies than both TADF and PHOLEDs

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.

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.
