Interviews with OLED market leaders

SID's DisplayWeek, the industry's leading trade show, is taking place in less than two months. The OLED-Info team will attend this event, and my good friend Sriram Peruvemba, SID's marketing chief, was kind enough to discuss the upcoming event with us.

Hello Sri, thanks for your time with this interview. SID's DisplayWeek has always been the world's leading display trade show. What can you tell us about the upcoming 2018 edition?

Ron - yes SID Display Week is the the world’s leading display trade show, but Display Week is so much more than a trade show. It is the world’s leading technical learning, sourcing and buying event focused on emerging electronic display technologies, their advancement, commercialization, and growth.

OrelTech is an Israeli-based early stage company that commercializes a unique printed electronics technology based on novel conductive ink and production process.

OrelTech's Head of R&D, Konstantin Livanov, was kind enough to explain the company's technology and business. Dr. Livanov received his PhD in chemistry from Weizmann Institute of Science, and his expertise is in surface chemistry, nanomaterials, composite materials and electron microscopy.

Q: Hello Dr. Livanov, thank you for your time. First, can you explain ORELTech's process and technology?

Sure. We are doing conducive ink for advanced applications in printed electronics. The advantages of printed electronics are obvious: drastically reduced manufacturing costs due to simpler equipment, fewer fabrication steps and shorter throughput time. However, most organic devices, including OLEDs, are not printed. We could however print them if we could print metal layers at low temperatures. Right now most of them are assembled or deposited in high vacuum.

Dr. Andreas Haldi was appointed as CYNORA's Chief Marketing Office in 2016. CYNORA develops efficient blue TADF OLED emitters, and Dr. Haldi was kind enough to participate in this interview and help us understand CYNORA's business and technology.

Q: Thank you Andreas for helping us understand CYNORA's business and technology better. CYNORA has set up on a focused mission to develop a commercial blue TADF emitter. What will you consider to be a market-ready material, in terms of lifetime, efficiency and color point?

For the last 5 years, CYNORA has worked on developing thermally activated delayed fluorescent (TADF) OLED emitters. End of 2015 we started to focus on efficient blue materials, which are still a key issue for OLED displays. Compared to the red and green pixels, the blue pixel is much less efficient. An increased efficiency of the blue pixel would therefore significantly reduce the power consumption of the display.

Idemitsu Kosan is a large multinational Chemical company based in Japan that is supplying OLED materials for OLED producers. Idemitsu has OLED business units in Japan, Taiwan, Korea and China and is collaborating with UDC, LGD, AU Optronics, Doosan and others.

Hajime Nakamoto, the head of the Electronic Materials Department at Idemitsu was kind enough to answer a few questions we had. Mr. Nakamoto joined Idemitsu in 1984 and has been involved with OLEDs since 2007.

Q: Hajime, Thank you for your time. Idemitsu has been one of the leaders in OLED materials for a very long time. Can you tell us what kind of materials you currently offer for OLED panel makers?

Idemitsu offers almost all kinds of OLED materials to OLED panel makers. Idemitsu is particularly well-known for its fluorescent blue host and dopant materials and transport materials, which offer advantages to OLED panel makers.
