OLED-Info interviews - Page 4

Universal Display Corporation (UDC) is one of the most known OLED company, involved with OLED IP, OLED phopshorescent materials, innovations on flexible OLEDs, production processes and more. As the most prominent public OLED company, the company is interesting to many investors and analysts.

Last year UDC hired Darice Liu to handle communications and investor relations. Darice was kind enough to answer a few questions I had regarding UDC's technology and business. These are interesting times for UDC as the OLED market is growing quickly, OLED TVs and flexible OLEDs are finally appearing on the market, but on the other hand the company is being faced with patent litigation and criticism from some investors (whom I shall not name).

A few weeks ago I posted about Plastic Logic's OTFT-based AMOLED demonstration. While the company's current demo is a simple display (monochrome white), it seems that Plastic Logic believes that OTFT technology is now reaching a performance level for adoption in AMOLED displays.

I discussed this with Mike Banach, Plastic Logic's Research Director. Mike (and the rest of the team at PL too, of course) says that organic semiconducting materials have reached a "tipping point" in electrical performance that makes them viable to drive flexible OLED displays. Couple this with the industrial and flexibility benefits of using solution-based organic materials makes it a compelling technology option for display makers looking to establish a position in the flexible display market.

Alkilu, a new company established in 2013 to develop affordable consumer OLED lighting devices, unveiled their range of OLED products at CES 2014. And these indeed are affordable - some of those OLED lamps cost as low as $19.95.

The company's CEO, Alex Khayat, was kind enough to answer a few questions we had regarding the company and those OLED lighting devices. Alex has 25 years of technology experience, including nearly a decade of OLED industry R&D for Boston-based ieDisplay (an R&D company that sold its research to tech specific and similar companies).

StoreDot is an Israeli startup company that was established in 2011 to develop and commercialize new peptide-based technology originally discovered in Tel Aviv University. Storedot's technology allows them to synthesize new nano materials ("inspired by nature") that can be used in a wide variety of application - displays, batteries, memory and more.

StoreDot invited me for a visit in their offices (thanks guys!) to learn more about the company and the technology. The company's display technologies may compete and complement OLED panels, so this should be an interesting company to watch.

In October 7, LG Display announced that it will soon start mass producing flexible OLEDs. Today we have talked with LG Display officials, and they confirmed that mass production has indeed started. The company currently makes 6" panels that weigh just 7.2 grams are are only 0.44 mm thick (only a third of the thickness of LG's thinnest mobile LCDs).

LGD updates us that the current flexible OLED production capacity in their 4.5-Gen line is 6,000 substrates a month (previously we reported that capacity will be 12,000 substrates). Perhaps the rest of the capacity is dedicated to R&D. In any case 6,000 substrates a month means almost 400,000 6" panels - assuming 100% yields. Of course yields will be lower but it seems that LGD indeed means to produce a fair share of displays and it'll be interesting how they (or other companies) adopt these panels in products.

OLED Encapsulation is a very hot topic, especially for flexible OLEDs. Samsung and LG are already producing flexible OLEDs, but the search for better encapsulation technologies is still on. ALD, or Atomic Layer Deposition is one candidate for future deposition of OLED encapsulation. ALD is based on Chemical Vapor Deposition (CVD) that uses two vapors (gaseous) precursors which react on the substrate which creates a solid thin film. ALD works in relatively low temperatures which means it is suitable for all substrates including plastics.

One of the leaders in ALD is Finland's Beneq. Beneq developed an inorganic barrier film called nClear which is deposited using ALD. Beneq says that nClear provides "world class" barrier performance and can be deposited at temperatures well below 100 degrees Celsius. Beneq offers the TFS-600 (Gen-2.5, 500x400 mm) which is used for industrial-scale OLED encapsulation. Beneq's director of Technical sales, Mikko Soderlund, was kind enough to answer a few questions we had on the company's technology and business. Mikko is leading the application development and commercialization of ALD-based thin-film encapsulation technology for OLEDs. He has a PhD in Photonics from Helsinki University of Technology (2009).

Corning recently announced the new second-gen Lotus XT high-performance glass suitable for OLED displays. The company has been supplying glass substrate and cover glass for OLED displays for years now. Now Corning was kind enough to participate in a Q&A session here on OLED-Info to better explain how they see the OLED market and what the future holds for Corning and OLEDs.

We talked to two Corning executives. John Bayne is Corning's High Performance Displays VP and General Manager, while Harrison Smookler is the commercial director and program manager of Willow Glass Substrates (flexible glass).

It seems that a lot of people (more than one, honest) want to know more about me, and how I got interested in OLEDs. It seems like a very strange turn of events for me too, but that's how life goes.

So my name is Ron Mertens, 38 years old from Herzelia, Israel (near Tel-Aviv), where I live with my two beautiful daughters. I'm a software engineer by trade, and from 1998 to 2005 I worked for three different companies (coding and designing software modems, compilers and ad delivery networks).

Merck is a global pharmaceutical and chemical company based in Germany, working on high performance OLED materials. We're happy to post this third interview with Merck's OLED unit VP, Dr. Udo Heider:

Q: Dr. Heider, thanks for taking the time to do yet another interview with us.

Thanks Ron. I do appreciate this opportunity to communicate about our recent Merck OLED activities.

I'm assuming that Merck is still focused on Solution Processable materials. Can you give us a short update on the current status of your materials?

Yes, of course, we are very diligently focused on solution processable materials development based on our customers requests. As communicated in the past, Merck is working on solution processable small molecule materials. Our chemists have devised ways to redesign an evaporable small molecule and optimize its performance within a soluble device stack, applicable to the various soluble "printing" process windows.

Sony's OLED program is now focused on medium (7" to 25") OLED panel used in professional monitors. With consumer OLED TV coming from Samsung and LG soon, Sony is also considering entering this market. We had the good chance of talking with Gary Mandle, the product manager of Sony's OLED products for the professional market. Gary has worked within the Sony Professional Solutions Group for more than 26 years in the development and marketing of new display products - including CRT, SXRD (LCOS), LCD, and now OLED products. His current focus is on Sony’s OLED technologies intended for video and film production & post production applications.

Q: Sony is currently offering 7.4", 16.5" and 24.5" professional OLED monitors (TriMaster EL^TM) and also OLED monitors for the medical market. Can you update on your current offerings?

A: For professional television and film production, Sony now has seven OLED models. These are offered in three series, each categorized according to performance and features sets to match different applications. Our PVM lineup includes the PVM 740 (7.4 inch), PVM 1741 (17 inch), and the PVM 2541 (25 inch). These are used in areas where you need something that is relatively cost effective and lets you see within the image. These are used in editing, dallies review, graphics generation, and special effects.
