OLED-Info interviews - Page 3

In May 2017 Cynora announced a new blue TADF emitters that achieves a 15% EQE at 1000 nits with an emission peak of 470 nm and a LT97 of > 90 hours (at 700 nits) on a device level. Cynora has stated several times that it aims to commercialize its first highly efficient blue TADF emitter by the end of this year.

According to Cynora, the performance requested from customers is an EQE (at 1000) of over 15%, a lifetime (LT97 at 700 nits) of over 100 hours and a wavelength of 460 nm (color purity FWHM 60 nm).

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.

Kateeva recently announced a large $88 million Series-E funding round, and the ink-jet equipment maker today announced that Ink-Jet guru Eli Vronsky has been promoted to the company's Chief Product Officer.

During our recent visit to San Francisco, we caught up with Kateeva’s executive team on a break from their presentations on inkjet printing for flexible OLEDs. Chief Product Officer Eli Vronsky gave us an update, as well as an overview of the company’s product strategy.

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.

In August 2015 Polyera, a US-based OTFT backplane developer, announced their first product, the Wove Band flexible E Ink smart band, to be released in the second half of 2016. Our sister-site E-Ink-Info posted an interesting interview with the company's Special Projects VP, Brendan Florez.

Brendan explains the company's OTFT backplane technology and details Polyera's business and goals. Polyera's backplane has been demonstrated to drive an OLED display in the past, so hopefully OTFT OLEDs will be coming from Polyera in the future. Read the full interview here.

LG Display is one of the two companies that lead the OLED industry, and the Korean display maker recently announced a major shift in focus from LCD displays to OLEDs. We conducted a short interview with an official from LGD regarding the company's OLED business goals and aims.

Q: LGD's CEO recently gave a very exciting speech regarding OLEDs, as the company shifts its focus towards OLEDs. What made you take that decision? How do you see the OLED TV market evolving in the next few years?

Market competition is getting fiercer with Chinese manufacturers rapidly catching up in terms of technology and capacity. In response, we recognize that differentiation in product and technology is essential to growth and maintaining leadership in the display industry.

DuPont has been working on OLED materials and processes for a long time, but it's been a while since we heard any update. David Flattery, DuPont's OLED unit Director of Operations was kind enough to update us on the company's materials and OLED technologies.

Q: Dave - thanks for this interview. We know that DuPont is focusing on soluble OLED materials and processes. When do you see the OLED display industry starting to adopt such materials?

DuPont is focused on developing OLED materials for evaporation and soluble technologies, as well as working with our partners on our proprietary printing process.

Many in the industry believe that 2017 will be the year of mass production for printed OLED televisions, and while we cannot disclose the manufacturing plans for our partners, we have already seen one large manufacturer announce that they will pilot solution- processed OLED displays up to gen-8 in 2015.

Germany-based AIXTRON is a leading deposition equipment provider for the semiconductor industries - used for a wide range of applications, from LED to graphene deposition. For the OLED market, Aixtron is offering Organic Vapor Phase Deposition (OVPD) equipment (which was exclusively licensed to AIXTRON by Universal Display).

Juergen Kreis, AIXTRON's Director Business Development, was kind enough to update us on Aixtron's OLED business and answer a few questions we had on the company's technology. Juergen joined AIXTRON in 2010 as Director Business Development with special focus on the portfolio for organic material deposition solutions.

Q: Hello Juergen. Can you give us a short introduction to AIXTRON's OLED related products and services?

AIXTRON’s core expertise clearly is in the offering of proprietary process solutions for the deposition of organic thin-films, with OVPD (Organic Vapor Phase Deposition) and PVPD (Polymer Vapor Phase Deposition) being the core process technologies. As the fabrication of organic electronics requires many manufacturing steps, flawless integration of the respective processes into an automated material flow is essential.

Several OLED markets are heating up - OLED TVs, Flexible OLEDs, wearables, OLED lighting, the automotive market... Barry Young from the OLED Association, one of the world's top OLED experts, was kind enough to offer his views and opinion on the OLED market.

Q: What is your expectation from the OLED TV market in the next 1-3 years? Will LG be the only player (and if so what will be their capacity) or will Samsung and perhaps other enters the market too?

LG chose to implement the metal oxide/White OLED approach and has succeeded, where Samsung’s choice of LTPS/Small Mask Scanning (SMS) has proven too expensive to pursue even with ~80% yields.

Philips' OLED lighting division has a new head of Marketing and Business Development - Jay Kim. Before he was responsible for OLED product marketing, business development, MarCom and customer services functions globally, Jay headed Philips' industry segment marketing in Europe involving Philips LED luminaries, lighting controls and services. And he was kind enough to agree to this interview here at OLED-Info.

Q: Jay - thanks for your time. Let's jump, shall we? In March 2014 Philips announced the FL300, your brightest OLED yet at 300 lumens. Any updates on this panel? Is it still on track for Q3?

We are very happy with the performance of the new Brite FL300 and its acceptance in the market. Already before official market introduction at Light+Building we have had three designs where the brightest OLED on the market is used. Italian furniture maker Riva1920 uses our OLED in its K BLADE lamp, an exceptional beautiful wooden desk lamp combining 48,000 years old Kauri wood from New Zealand with the world’s most modern lighting technology OLED. Besides that, German Designer Thomas Emde is using the Brite FL300 in its new series of OLED luminaires sold under the label OMLED. In addition, he is working closely together with Italian luminaire manufacturer Luceplan. Together they bring the OLALAL OLED luminaire to the market. Also, many of our customers with designs based on the Lumiblade GL350 OLED are going to switch to the new OLED as well.
