TADF materials developer Kyulux announced that it has finalized its Series-B-prime funding round, raising $34.3 million USD from several VCs and companies. Kyulux will be able to now accelerate its product development and drive for adoption of its materials in smartphone OLED displays.

Kyulux also announced plans to establish a mass production system for its materials, in cooperation with chemical companies.

TADF OLED materials developer Kyulux announced a new CEO and President, to replace the current CEO Mr. Junji Adachi. Mr. Nakano will become the company's new CEO starting February 11, while Junji has been appointed as Chief Strategy Office. This is a part of a wide management change at Kyulux that reflects the company's transition from material development to commercialization.

Mr. Nakano has an impressive industry background in addition to management positions, and since 2014 he was an executive officer and manager director of Japan's Innovation Network (INCJ).

TADF emitter developer Kyulux announced that has signed a joint-development agreement with Nippon Soda to develop new intermediates compounds for TADF emitters. The goal of this collaboration is to improve the performance and quality of Kyulux's TADF materials, and also dramatically improve the production efficiency of new compounds.

This agreement also markets Nippon Soda first entry into the OLED market. The company, founded in 1920, is highly environmentally conscious and has accumulated advanced organic material development capabilities and vast synthesis know-how, which will assist it in this new OLED project.

Due to the global COVID-19 pandemic, the 5th annual International TADF Workshop and the 3rd i3-opera Forum, a companion event aimed at industry researchers, will be held on December 78 by means of online live streaming.

In the Workshop, novel scientific concepts will be discussed, as well as the future direction of TADF-OLEDs, perovskite LEDs, radical-based LEDs, QD-based LEDs, novel materials-based LEDs and more. In the Forum, the scope will be extended even further, to include topics ranging from TADF frontier science to interdisciplinary technologies for future lifestyle.

Kyulux presented a new paper at SID Displayweek, that shows the latest progress of the company's Hyperfluorescence OLED emitter platform. You can see the latest performance chart below.

Hyperfluorescence combines TADF and fluorescence emitters, which enables high-efficiency (~100% IQE) emitters that feature long lifetimes and a very narrow emission spectrum. The company's yellow HF emitter is already commercialized, and now Kyulux says that its red and green materials are "close to commercialization". The company is also improving the color point and lifetime of its HF blue emitters.

WiseChip Semiconductor, based in Taiwan, is one of the world's leading PMOLED maker (in fact in 2015 Wisechip said it's the world's second largest). Wisechip is developing next-generation PMOLED displays, including flexible panels, transparent panels and Hyperfluorescence/TADF PMOLEDs.

WiseChip recently announced its first, and the world’s first, Hyperfluorescence display, using TADF materials provided by Kyulux. Can you tell some more about this display and its properties?

This 2.70 128x64 product is adopted mostly in industrial products. The size matters in such market but the main problem was to increase the brightness due to the limited efficiency of the fluorescence emitters. The Hyperfluorescence technology helps to settle the problem and can reach up 2.5 times brighter. It performs much better readability so users do not have to stand right in front of the device. This feature adds to the value of the end product.

TADF emitter developer Kyulux announced that it has shipped the first batch of its yellow TADF emitter to Taiwan's Wisechip to be used it the world's first TADF / Hyperfluorescence display, the 2.7" PMOLED announced in October 2019 - which means that the display will likely start to ship soon.

Wisechip's first HF PMOLED is a 2.7" 128x64 monochrome yellow display, that reaches a brightness of 220 nits - 2.5 times brighter than Wisechip's fluorescent yellow PMOLED. The lifetime of this display is 50,000 hours. Wisechip says this display is aimed for the medical, industrial and electronic products markets, and in the future it will launch TADF/HF PMOLEDs for the wearable and consumer electronics markets as well.

TADF, or Thermally Activated Delayed Fluorescence, is a relatively new class of OLED emitter materials that promise efficient and long-lifetime performance without any heavy metals. TADF research started at around 2012, originally at Kyushu University in Japan and today many academic groups and several commercial companies are developing TADF materials.

The main reason companies are interested in TADF emission is that it could lead to an efficient and long-lasting blue OLED emitter - something that hasn't been yet achieved by other means (mainly - UDC's Phosphorescent OLED emitter technology). In recent years companies initiated commercial development of red, green and yellow TADF emitters as these can offer a lower cost alternative to UDC's PHOLEDs materials.

Wisechip announced that it launched the world's first Hyperfluorescence OLED display - a 2.7" monochrome yellow 128x64 PMOLED. The brightness of this display reaches 220 nits - which is 2.5 times the brightness of Wisechip's fluorescent yellow PMOLED. The lifetime of this display is 50,000 hours.

Hyperfluorescence OLED emitters represent the 4^th-generation of OLED emitter systems. HF is an actually a system that combines fluorescence emitters (1^st-gen) with TADF (3^rd-gen) hosts - to achieve a high efficiency , long lifetimes and narrow-spectrum emission.

TADF and Hyperfluorescence developer Kyulux announced that it finalized its Series B financing round, having raised ¥1.5 billion ($31.8 million USD) from several companies and VCs. Kyulux says it will use the funds to further accelerate product development and strengthen its IP.

A couple of months ago Kyulux updated on its latest TADF device that achieves 200 hours of lifetime (LT95 at 1000 nits) and an EQE of 22% (at 1000 nits). The color point is 470 nm (which is not deep-blue, note). Kyulux also says that Wisechip is now ready to start producing the yellow HF PMOLED and is seeking customers.
