Sumitomo Chemical developed a new 6.5" OLED panel
Sumitomo Chemical has developed a new 6.5" AMOLED panel. It's a polymer-based OLED made by printing technology, sealed by a metal plate. It was made by Sumitomo's "Device Development Center," which was established in August 2009.
Sumitomo and Idemitsu Kosan say that 2012 will be the year when OLED finally takes off
In an interesting article by the Financial Times, both Idemitsu Kosan and Sumitomo executives estimate that "2012 will be the year when OLEDs hits the big times".
Idemitsu Kosan also says that they are working on a new way to 'spray' small-molecule OLED materials. The new method should be ready by 2015. Spraying OLEDs (instead of using vapor-deposition) will mean less material loss, and thus cheaper displays. It will also make it easier to fabricate large panels.
Interview with David Fyfe, CDT's Chairman and CEO
CDT is one of the leaders in OLED research, focusing on Polymer-based OLEDs (PLEDs, also called P-OLEDs). While these OLEDs are lagging behind small-molecule OLEDs in current products (all AMOLEDs today are based on SM-OLEDs), some companies believe that PLEDs are actually the better tech for the future.
CDT's CEO, David Fyfe has agreed to answer a few questions we had on CDT's technology. David joined CDT in 2000 as Chairman and CEO. David saw CDT go public in 2004, and then negotiated the sale of CDT to Sumitomo for $285 million (in September 2007). David is also a director of Soligie, an electronics printing company, Acal Energy, a fuel cell technology developer and the Plastic Electronics Foundation.
Q: David - thanks for agreeing to do this interview. Since the Sumitomo acquisition, CDT has been rather quiet... can you give us an update on where's the company now, and where's it is headed?
Since the merger of CDT into Sumitomo Chemical in September 2007, CDT has grown substantially and received considerable capital investment to enable it to remain a leading developer of PLED technology. It works very closely with SCC laboratories in Japan and most recently has been transferring manufacturing process knowhow to SCC's own PLED manufacturing development line, recently commissioned at Ehime on Shikoku, Japan. CDT in partnership with SCC has made large strides in materials lifetimes and efficiencies. SCC prefers to take a lower profile in announcing these advances since its business model is to work with selected display maker partners in a collaborative, confidential relationship. We have also made big strides in the development of top emitting structures and in printing PLED displays. SCC's strategy is that CDT will continue to be its leading development center for PLED technology with Ehime scaling process technology to a yielding process status. CDT is also working very closely with Semprius of North Carolina, USA to develop single crystal silicon TFT structures on which PLED devices can be deposited and driven using Semprius’ proprietary stamping technology.
Q: It seems that OLED displays are finally entering the mainstream - we hear of new devices (mainly by Samsung, but also from Sony, Microsoft, LG and others) almost daily. What are your thoughts on this? what are the challenges that still exist for OLEDs?
Sony broke the logjam of resistance to the adoption of OLED in large displays by major display makers with the introduction of its XEL-1 11 OLED TV in 2007. Samsung SDI’s investment in small screen OLED production in 2007, based on LTPS backplanes was another major impetus. Since then, Chi Mei has brought on small OLED screen capacity, TMD (now wholly owned by Toshiba) has built an OLED line to manufacture small screens, LG Display will start up their Gen 3.5 line late this year and if press reports are to be believed, Toppoly will commission their capacity with Nokia as a lead customer and Panasonic have a major OLED development program for large OLED displays.
Panasonic teams up with Sumitomo for OLED TVs
Panasonic has announced that they are developing OLEDs together with Sumitomo. They aim to make 40" (or bigger) TVs by 2010. Back in 2008, Sumitomo announced plans for OLED TVs by 2009, and were seeking partners for doing it.
Sumitomo's technology is based on CDT's PLED materials (CDT were acquired by Sumitomo back in 2007).
Nanomarkets: the markets for OLED materials will reach $2.7 billion by 2015
After receiving investments totaling billions of dollars over the past decade, the OLED industry is finally poised to take off. According to NanoMarkets, an industry analyst firm based here, the markets for OLED materials will reach $2.7 billion by 2015.
Key Findings:
- The recent announcement by Nokia requiring its vendors to be capable of producing OLED displays is a strong indication that OLED technology is about ready for broader commercial production. GE Global Research's success with roll-to-roll production of OLED devices indicates that OLED lighting may result in greater near term production volume than displays. Sony meanwhile has launched the world's first OLED TV. The rise of lighting and television applications, in particular, are positive for materials suppliers, because these applications require large OLEDs and hence use much more material than the small cell phone and MP3 player displays that have until recently dominated the OLED space.
OLED: towards a mature industry - interview with Gildas Sorin, CEO of Novaled AG
In July 2008, I had the chance of interviewing Gildas Sorin, Novaled's CEO. Novaled is engaged in the commercialization of the new generation of OLEDs. Novaled developed an innovative doping technology (Novaled PIN OLED) enabling large area OLED display and lighting.
Novaled claims to deliver the highest power efficiencies in combination with longest lifetimes and holds several OLED world records.
Novaled, established 5 years ago, is located in Dresden, Germany. Dresden city is becoming the biggest European organic electronic centre with a network of university, R&D centers and companies acting in the organic fields.
Japanese government and companies team up to develop OLED tech
The Japanese government will team up with several Japanese companies to develop key-technologies for producing large-size OLED panels. The aim is to cut the development cost for the Japanese companies, to be better able to compete against Samsung and LG, and the Japanese government will pitch in around 32$M.
The project will also try to make the displays more efficient and have longer lifetime.
One report says the project will run till 2013, another that it will run until 2015, and the aim is to produce 40" OLED TVs by then. We'll have to wait and see...
The companies include -
- Sony
- Toshiba
- Matsushita
- Sharp
- Idemitsu Kosan
- Sumitomo chemical
- Dainippon Screen Mfg
- Shimadzu
- Hitachi
Interesting to see Sharp in there, after having stated that "OLEDs will not threat LCD for at least a decade".
Interview with Dr. Goeff Williams, Project TOPLESS manager
In June 2008, I had the chance of interviewing Dr. Geoff Williams, Topless's project manager. Geoff has a PhD from University of Durham, and later worked in Philips Displays and he now works in Thorn lighting.
CDT, Sumitomo Chemical and Novaled will collaborate to evaluate Novaled PIN OLED structures in Polymer OLED devices
CDT, Sumitomo and Novaled plan to co-develop hybrid OLED devices combining both new polymer emitting layers and doped electron transport layers. It is expected that these hybrid devices will offer further improvements in power efficiency without additional manufacturing complexity. The parties have reached an agreement on how IP generated during the JDA will be handled. Further, Novaled will grant a license to CDT enabling CDT to add necessary Novaled device IP to its existing and future licenses. Each company will remain responsible to market its own materials resulting from this co-development.
CDT continues to focus its effort on supporting the PLED supply chain and is pleased to be involved in yet another joint development project which has the potential of bringing new materials and improved device performance to our licensees, says David Fyfe, CEO of CDT.
Barry Young establishes the OLED Association
There's a new OLED group that has just been formed - the OLED Association (OLED-A). The group is managed by Barry Young (Former senior VP, Display Search).
There are ten members in the group - Cambridge Display/Sumitomo, Corning, DuPont, Kodak, eMagin, Ignis, MicroEmissive Displays, Novaled, OLED-T, Samsung SDI, and Universal Display, and OLED-A are working to add more members.
