OLED ink jet printing: introduction and market status - Page 25
Interview with Gerd Guenther, Novaled's marketing chief
We had the good chance to talk with Gerd Guenther, Novaled's Chief Marketing Officer. He was kind enough to answer a few of our questions, and give us some information and updates from Novaled.
Gerd, thanks for your time. Can you explain Novaled's business model to us?
When Novaled started as a spin-off from Fraunhofer and Technical University of Dresden in 2001 with just 3 people, the idea was to market its doping technology Novaled PIN OLED®) along with its proprietary materials. Today, quite an impressive number of well known display and lighting makers are customers of Novaled. That means we offer IP, licensing and technology transfer packages but also R&D contracting as well as trainings.
Plextronics announces solution-processible PHOLED HIL ink availability
Plextronics announced today that its Plexcore OC NQ ink is now available - for limited sampling. During 2011 Plextronics will accelerate production. The new non-aqueous-based Hole Injection Layer (HIL) ink is geared specifically for solution processible phosphorescent OLED emitters, and Plextronics expects to introduce ink-jet printable inks for limited sampling early in 2011.
Plextronics also say that UDC was using their OC NQ ink in their new P2OLED solution-processed phosphorescent OLED technology (reported on October 13). Plextronics was the HIL provider, and its OC NQ ink helped UDC to achieve a lower operating voltage and a boost in lifetime over previously disclosed results.
UDC announce significant advances in solution-processible OLED materials
Universal Display announced today "significant advances" in the performance of its UniversalP2OLED solution-processible, phosphorescent OLED material systems. UDC reported that the solution-based system now approach the performance of vacuum-evaporated PHOLEDs.
The new green system feature 66 candelas per Ampere (cd/A) and 130,000 hours lifetime at 1000 nits luminance. That's about two times improvement from a year ago. The new red system offers 15 cd/A and 62,000 hours, and the light blue offers 18 cd/A and 5,000 hours. UDC has also demonstrated ink-jet printing with comparable performance to devices made by spin-coating.
Roth & Rau joins Holst Centre research on barriers for flexible electronics
Roth & Rau MicroSystems will partner with the Holst Centre on barriers for flexible electronics. The two companies will develop and install a roll-to-roll PECVD deposition tool in the Holst Centre. This will be used for flexible OLED lighting and organic solar cells.
Q&A with Verbatim's OLED team
Back in February, Pioneer and Mitsubishi Chemical has announced an OLED Lighting JV. Pioneer will produce OLED lighting panels, Mitsubishi Chemical will supply chemicals and will market and sell the panels through their Verbatim daughter company.
We had the good chance to speak with Verbatim regarding this new OLED business.
Q: Are there any updates on the OLED JV?
Mitsubishi Chemical Corp will start to supply samples at the end of 2010, and mass production in the middle of 2011.
Konica-Minolta to start making flexible OLEDs in 2010?
OLEDNet reports the Konica-Minolta plans to start mass production of flexible OLED lighting panels in 2010. Konica-Minolta is cooperating with GE on manufacturing technology. According to the report, Konica Minolta is using polymer materials and printing technologies. The materials are made by Sumitomo. The lifetime of Konica-Minolta’s products is estimated to be 3,000 hours or more with the brightness of 1,000 cd/m2.
We think that this is a bit optimistic... according to KM's own plans, the first plant is scheduled for March 2011. Just last month they re-iterated their plans to start making the flexible OLEDs in 2011, and we do not think this will qualify as 'mass production'. We also know that KM is using UDC's Small-Molecule Phosphorescent materials, but maybe they are also working with Sumitomo on Polymer based OLEDs.
Novaled to become an OLED Lighting manufacturer?
Update: According to Novaled, this report is not true. They are set to remain in the IP & Material business, in both OLED displays and lighting.
According to OLEDNet, Novaled is set to become a manufacturer of OLED Lighting panels (instead of being a supplier of OLED materials and technology/IP). They are moving away from displays because they lost the "competitive edge" to Korean companies.
Novaled is focusing on flexible OLEDs based on stainless steel substrate. They will introduce a 150x150mm, 25lm/W, 10,000 hours white-OLED panel in 2010. In 2011 they will add a 200x200mm, 40lm/W, 25,000 hours panel. In 2012 they will improve this to 50lm/W, 50,000 hours. By 2012, their OLEDs will be flexible, too (using roll-to-roll manufacturing process).
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.
Dupont says they can print a 50" OLED TV in under two minutes
A few days ago, DuPont has unveiled new printable OLED materials. DuPont now say that they can print a 50" OLED TV in under two minutes. They are using a custom-made printer from Dai Nippon Screen Manufacturing Co.
Dupont worked with Dai Nippon Screen to develop a multi-nozzle printer for the new inks. The Dai Nippon printer generates a continuous stream of ink, rather than droplets, and moves over a surface at rates of four to five meters per second while patterning a display.
Dupont reports new record lifetime performance for printed OLEDs, enough for OLED TVs
Dupont announced new record lifetime performance in printed OLEDs for displays. They say that this is sufficient for OLED TVs. The new Gen 3 solution-processable OLEDs offer 29,000 hours for red, 110,000 for green and 34,000 for blue (at typical TV brightness levels). This is enough for 8 hours per day over 15 years...
Back in 2009, Dupont reported even better lifetime for OLEDs. But these new materials can be used in a printing process, which should make it cheaper and easier to produce OLED TV displays. DuPont has produced some test devices with the new materials and will show them at SID.
