Vitex expands ANS agreement, Samsung SDI uses their systems


Vitex System today announced that it has
expanded its license agreement with Korea-based Advanced Neotech Systems
(ANS), granting ANS rights to develop and manufacture roll-to-roll coating
equipment used in the production of Barix™ Barrier Film.



Vitex made the first agreement with ANS in 2006, allowing ANS to make Barix encapsulation equipment, the Guardian™ System.
ANS has successfully sold eight Guardian systems to produce Vitex's
proprietary Barix technology, including: a pilot system being used by
Samsung SDI to make the world's first foldable OLED
and the thinnest OLED
display that was shown at FPD International 2008 in Yokohama; the first
mass production system; and the first Gen 2 (370mm x 470mm) system. 



Over the past year, Vitex has made excellent progress demonstrating the
unique capabilities of its Barix Barrier Film for encapsulation of
thin-film photovoltaic cells. Multiple companies have been able to verify
that, when protected by Vitex's Barix Barrier Film, their thin film
photovoltaic (PV) cells fabricated using either CIGS or CdTe can pass the
damp heat test required by the IEC 61646 standard.

HP and Arizona State University Demo Flexible, Unbreakable Displays

HP and the Flexible Display Center (FDC) at Arizona State University (ASU) today announced the first prototype of affordable, flexible electronic displays.


The unbreakable displays were created by the FDC and HP using self-aligned imprint lithography (SAIL) technology invented in HP Labs, HP’s central research arm. SAIL is considered self aligned because the patterning information is imprinted on the substrate in such a way that perfect alignment is maintained regardless of process-induced distortion.


SAIL technology enables the fabrication of thin film transistor arrays on a flexible plastic material in a low-cost, roll-to-roll manufacturing process. This allows for more cost-effective continuous production, rather than batch sheet-to-sheet production.


The first practical demonstration of the flexible displays was achieved through collaborative efforts between the FDC and HP as well as other FDC partners including DuPont Teijin Films and E Ink. To create this display, the FDC produces stacks of semiconductor materials and metals on flexible Teonex® Polyethylene Naphthalate (PEN) substrates from DuPont Teijin Films.


HP then patterns the substrates using the SAIL process and subsequently integrates E Ink’s Vizplex™ imaging film to produce an actively addressed flexible display on plastic. E Ink’s Vizplex bi-stable electrophoretic imaging film enables images to persist without applied voltage, thereby greatly reducing power consumption for viewing text.

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.

GE Demonstrates World's First ''Roll-to-Roll'' Manufactured OLEDs

GE Global Research today announced the successful demonstration of the worlds first roll-to-roll manufactured OLED lighting devices. This demonstration is a key step toward making OLEDs and other high performance organic electronics products at dramatically lower costs than what is possible today.

Researchers have long dreamed of making OLEDs using a newspaper-printing like roll-to-roll process, said Anil Duggal, manager of GEs Advanced Technology Program in Organic Electronics. Now weve shown that it is possible. Commercial applications in lighting require low manufacturing costs, and this demonstration is a major milestone on our way to developing low cost OLED lighting devices.

Duggal continued, Beyond OLEDs, this technology also could have broader impact in the manufacturing of other organic electronic devices such as organic photovoltaics for solar energy conversion, sensors and roll-up displays.

For businesses, architects, lighting designers and anyone interested in pushing the envelope to achieve increasingly energy-efficient lighting — and vastly expanded lighting design capabilities — today marks the day that viable, commercialized OLED lighting solutions are coming into view, said Michael Petras, GE Consumer & Industrials Vice President of Electrical Distribution and Lighting. We have more work to do before we can give customers access to GE-quality OLED solutions, but its now easier to envision OLEDs becoming another high-efficiency GE offering, like LEDs, fluorescent or halogen.

The demonstration of a low-cost, roll-to-roll process for OLED lighting represents the successful completion of a four-year, $13 million research collaboration among GE Global Research, Energy Conversion Devices and the U.S. Commerce Departments National Institute of Standards and Technology (NIST). The goal of the collaboration was to demonstrate a cost-effective system for the mass production of organic electronics products such as flexible electronic paper displays, portable TV screens the size of posters, solar powered cells and high-efficiency lighting devices.

ECD Senior Vice President Nancy Bacon said, This program was a major step in developing high volume roll-to-roll manufacturing for OLEDs and other organic semiconductor devices. The success of this program is testimony to the effectiveness of NISTs advanced technology program model, and our 20-year history of pioneering research in roll-to-roll technology. We currently are utilizing this technology to mass produce our flexible, durable and lightweight UNI-SOLAR brand solar laminates. ECD looks forward to continuing collaboration with GE to further develop this technology for future commercialization.

GE researchers provided the organic electronics technology and were responsible for developing the roll-to-roll processes, while ECD provided its unique roll-to-roll equipment-building expertise to build the machine that manufactures the OLED devices. The machine is being utilized for further manufacturing research at GEs Global Research Center in Niskayuna, New York.

The development of this low cost roll-to-roll manufacturing process has the potential to eliminate the manufacturing hurdles that currently exist in preventing a more widespread adoption of high performance organic electronics technologies such as OLED lighting. The unique commercial equipment and technology needed to enable high performance-based organic electronics products does not currently exist. The few organic electronics products on the market today are made with more conventional batch processes and are relatively high cost. A roll-to-roll manufacturing infrastructure that enables high performance and low cost devices will allow a more widespread adoption of organic electronics products.

Europe targets research and development of lighting foils for lighting applications

Europe joins forces in the form of a new integrated R&D project that aims to research and develop light emitting foils based on OLED technology. A group of 14 companies, research institutes and universities, leading in the fields of printing and electronics has formed the consortium of Fast2Light and will align efforts to demonstrate that high quality and cost-efficient lighting foils are the future for lighting and signage applications.

"The steady progress of light-emitting materials in recent years, identify OLED technology as the next solid-state, large-area light source. Within this project consortium we are able to combine European leading partners in the fields of printing, electronics and roll-to-roll processing and to create critical mass for the development of OLED lighting foils. Fast2light aims to set in place the manufacturing platforms so as to accelerate the introduction of lighting foils into the market when the light-emitting polymers meet the product specs" said Mary Kilitziraki of Holst Centre, project manager of Fast2Light.

The project, partially funded under European Union’s 7th Framework program as part of the ICT (Organic and large area electronics, visualisation and display systems) priority, will address all layers that are part of a lighting foil. It will start with the plastic substrate, and introduce high-throughput deposition and patterning methods for all of the materials necessary to fabricate the final lighting foil. Ultimately, the project will demonstrate a 30cm x 30cm, high quality lighting foil, manufactured with new optimised, disruptive R2R processes. While the project will focus on polymers, the platforms developed will be fully compatible with SMOLEDs.
