The 3rd international TADF Workshop, organized by Kyushu University and i3-OPERA and supported by Kyulux, took place last week in Fukuoka, Japan.
The workshop covered the latest TADF advances – in materials, device architecture, applications and more. Kyulux’s CEO, Junji Adachi, gave a talk titled ” Material Informatics Driven Hyperfluorescence Development: A disruptive Innovation in OLED”. We were happy to see a large turnout at the event and we hope to be able to demonstrate our deep-blue Hyperfluorescent emitter at the 2019 workshop!
Today we have made an exciting announcement – Kyulux succeeded in improving the performance of its blue OLED Hyperfluorescence™ emitter.
Hyperfluorescence™ materials are the fourth-generation OLED light emitting technology. The result will be announced at The 3rd International TADF Workshop to be held in Fukuoka on July 19th. Kyulux has succeeded in extending the lifetime of its blue material while maintaining its high external quantum efficiency (EQE) of 20% or more, at practical brightness levels.
Kyulux’s latest material features an EQE of up to 26%, and specifically an EQE of 22% at 1,000 cd/m2 brightness. The emission wavelength is 470 nm at the peak value. The lifetime of the material is quoted at 100 hours at LT95 (at 750 cd/m2). An LT95 means that the brightness decreases 5% after 100 hours of use at a brightness of 750 cd/m2.
Kyulux’s Hyperfluorescence™ is the world’s top performing materials at the moment, and the company now aims to work together with OLED panel makers to improve the systems further by optimizing the device structure and the rest of the OLED stack in pilot production lines.
The Ministry of Economy, Trade and Industry (METI) has launched a new initiative called the “J-Startup” program, announced on June 11, 2018, aiming to incubate internationally competitive startup companies and encourage them to provide new value to the rest of the world through their innovative technologies and business models. As part of this program, METI will select promising startups and the public and private sectors will unite their efforts to provide them with intensive support measures, including those for their business development overseas.
In 2018, around 10,000 startups were reviewed for this program, and only 92 were selected to participate. Kyulux was among the chosen startups, further defining it as the one of the growing startups in Japan.
The premier display industry event, SID DisplayWeek, is now over – and it was a great week. Kyulux had a successful booth demonstration, with a lot of interest from display companies as HF/TADF emitter technology is maturing and is ready to be commercialized.
During the show, Kyulux unveiled Wisechip’s flexible HF PMOLED display, which we already posted on. This display is set to be the world’s first commercial HF display, and will hopefully enter mass production by the end of the year. Kyulux also demonstrated a smaller yellow PMOLED HF device, again produced at Wisechip. This is a 0.87-inch display with a resolution of 216×128. In the demonstration, Kyulux showed how the HF display is almost twice as bright (210 nits vs 110 nits) than Wisechip’s regular fluorescent PMOLED, using the same amount of power.
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!
