TADF OLED emitters, introduction and market status - Page 12

The first edition of the International TADF Symposium, hosted by CYNORA, is intended to provide a professional forum for industry and academia experts. During the symposium all aspects related to research and development of TADF OLED materials, from modeling through synthesis to analytics and device fabrication, will be covered and discussed in several lectures. The symposium, will take place in Frankfurt in the Hilton City Center Hotel, September 7, 2017.

Researchers from Osaka University managed to create multi-color Mechanochromic Luminescent (MCL) materials. The materials were found to exhibit efficient TADF emission, and the researchers developed an efficient OLED device based on these new materials.

MCL materials change their color in response to a change in their environment - for example pressure or temperature. Most MCL materials can only change between two colors, but the new materials can switch between yellow, red and orange. The color shift occurs in response to heating, fuming, and grinding.

In 2016, TADF (Thermally Activated Delayed Fluorescence) emitters have received much attention in the OLED industry as the most promising method to improve OLED displays. CYNORA is one of the most active companies with several years of experience in this field and the company is now getting ready to bring a first blue TADF material to the OLED market.

In a little more than one year, CYNORA has set itself up to become a major OLED material supplier. First, an experienced CEO in this field, Gildas Sorin, the former CEO of Novaled GmbH, was brought in. Since then, CYNORA has shown significant improvement in material performance starting with the announcement of two milestones.

TADF, or Thermally Activated Delayed Fluorescence, represents a class of OLED emitter materials that aim to provide efficient and long-lifetime performance. TADF research started in earnest in 2012, and some believe that TADF represent an exciting new platform for next-gen OLED emitters.

As OLED display adoption grows, researchers and developers at Universities and companies are looking to develop more efficient and cost-effective OLED materials. There are currently three main drivers for these efforts - the development of an efficient and long-lasting blue color emitter, the development of alternative non-phosphorescent emitters and the development of soluble materials that can be deposited in ink-jet printing and other "wet" methods.

Germany-based blue-TADF OLED emitter developer Cynora announced that it developed a new blue-emitting material that combines high efficiency with long lifetime. Cynora's new material offers an external quantum efficiency (EQE) of 14% and a lifetime of 420 hours (LT80, at 500 cd/m²).

In May 2016 Cynora announced two blue emitter systems - with one featuring a high efficiency and the other a long lifetime. This time Cynora managed to create a single system with both efficiency and lifetime. The company says that they are optimistic that they will reach a commercial TADF blue emitter by the end of 2017.

Blue TADF developer Cynora signed a MoU (Memorandum of Understanding) with Guangdong Juhua Printing Display Technology to cooperate on OLED TV development.

Johua was established earlier this year by CSoT (66%) and TianMa (34%) with an aim to industrialize printed OLED technologies. Johua Printing is an "open innovation platform" guided by the Chinese government that collaborates with both industry and universities to drive the progress of China's display industry and the GUangdong Province specifically.

Last week we reported about a new large-scale computer-driven material screening process that was developed by Researchers from Harvard University, MIT and Samsung.

The so-called Molecular Space Shuttle system combines theoretical and experimental chemistry, machine learning and cheminformatics, with an aim to quickly identify new OLED molecules (the system was already used to deisgn more than a 1,000 new high-performance blue-light emitting molecules). Today Kyulux announced that it secured a license to Harvard University’s Molecular Space Shuttle deep learning system.

Blue TADF developer Cynora announced that Dr. Andreas Haldi was appointed as its Chief Marketing Officer. With his strong technical and business experience, Andreas Haldi will reinforce Cynora in the forthcoming commercialization of its high performance blue OLED materials.

Cynora, preparing the commercialization of its emitting materials for OLEDs, is hiring Andreas Haldi to further enhance its already good relationships with the major display makers and to now prepare with them the implementation of its materials in their products.

In early 2016, Kyushu University in Japan spun-off a new start-up called Kyulux to commercialize the TADF emitters developed at the University. A few months later, Kyulux raised $13.5 million (from LG, Samsung, Japan Display and JOLED).

We have met with Kyulux's team at SID 2016, who updated us that the company is progressing fast on the way to commercialize those TADF emitters. The first products to be ready are green and yellow emitters. Kyulux says that its Hyper-fluorescence TADF emitters offer a superior performance compared to PHOLED emitters (in both intensity and color purity) - and they should also be priced lower - so the company aims to provide a viable alternative to UDC's emitters in the near future.

Germany-based OLED emitter developer Cynora announced it has made significant progress in its highly efficient blue OLED emitter material developments during the last 6 months. The company's materials are not yet ready for commercialization, but the company believes it is on its way.

Cynora develops TADF-based emitters, focusing on blue-color emitters. Cynora has developed deep blue material reaching an EQE of 16.3% (at 100 cd/m²) compared to 3% reached in October 2015, a factor 5 improvement in six months.
