The ISIS synchrotron at the Rutherford Appleton Laboratory, Oxfordshire, UK, has launched a second target station for neutron beams which will allow scientists to study a range of new systems: from polymers and materials that sequester carbon dioxide, to soft matter and biomaterials.

UDC Awarded $1.9 Million U.S. Department of Energy Contract to Accelerate Development of White OLED Lighting Products

oled — Thu, 24 Jul 2008 00:22:12 -0400

Universal Display Corporation today announced a $1,918,878, two-year U.S. Department of Energy (DOE) contract to develop a ceiling-based white OLED lighting system. Universal Display plans to use Armstrong World Industries as a key subcontractor to fulfill the requirements of the grant. Funded through the U.S. DOE Office of Energy Efficiency and Renewable Energy, this Solid-State Lighting (SSL) Program award supports the DOE’s long-term commitment to advance the development and market introduction of energy-efficient, solid-state white light sources for general illumination.

During this SSL Product Development Project, Universal Display and its subcontractor, Armstrong, will develop and deliver an integrated ceiling illumination system that is targeted to exceed the DOE’s 2010 performance goals. The white OLED lighting panels will be designed and fabricated by Universal Display using its high-efficiency phosphorescent OLED technology. The panels will then be integrated by Armstrong into its innovative TechZone™ open-architecture ceiling system. In addition, the team will deliver a white OLED lighting panel fabricated on a thin metallic foil substrate using Universal Display’s UniversalPHOLED and other OLED technologies, to demonstrate the commercial product potential of white OLEDs with a flexible form factor.

Merck and DELO Industrial Adhesives Form Strategic Partnership for OLED solutions

oled — Tue, 15 Jul 2008 09:35:38 -0400

Merck KGaA and DELO Industrial Adhesives announced today that they have formed a strategic partnership in the field of organic light-emitting diode (OLED) technology. Within the scope of their agreement, the companies plan to develop future system solutions for OLED applications. The companies will join forces to market OLED adhesive products from DELO through Merck’s extensive marketing and sales channels.

In addition, Merck and DELO intend to develop innovative materials for improved OLED sealants that will facilitate the entry of OLEDs into large-format display applications. OLEDs show a high potential as the display technology of tomorrow and already are being used in MP3 players and cell phones. Within the OLED technology, Merck offers light-emitting materials while DELO offers new adhesive systems required to produce OLEDs.

Merck’s OLED materials are characterized by high quantum efficiency and longevity and the adhesives developed by DELO reliably seal off the sensitive metal layers from oxygen and moisture. This considerably extends the life of OLEDs.

Japanese government and companies team up to develop OLED tech

oled — Thu, 10 Jul 2008 02:12:08 -0400

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.

USDC & Plextronics develop new hole-injection-layer technology for OLED displays

oled — Fri, 27 Jun 2008 07:54:23 -0400

The U.S. Display Consortium (USDC), a public/private partnership chartered with developing the flexible electronics and displays industry supply chain, today announced that a recent project with Plextronics, Inc., has aided in the development of a new hole injection layer (HIL) technology to enable broad commercialization of high-performance, low-cost, organic light emitting diode (OLED) displays. Plextronics is an international technology company that specializes in printed solar, lighting and other organic electronics.

Plextronics completed a $590,000 project with USDC to produce a new HIL technology that is expected to improve device performance by reducing surface roughness; improving charge injection; and allowing fine-tuning of work function. The materials that Plextronics developed utilize a new approach to conductive polymer chemistry that enables significant performance improvement. These HIL products will be cost competitive and a suitable replacement for currently used PEDOT: PSS materials.

OLED100.eu - a new EU OLED white light project to follow-up on OLLA, gets 30M$ funding

The companies behind the OLLA project (Philips, OSRAM, Siemens, Novaled and Franhofer IPMS) agreed to fund another OLED lighting project - the OLED100.eu, a follow-up project.

NexTechFAS: Slot-coated OLED Displays Could Hit Market in 2010

oled — Sun, 22 Jun 2008 02:19:33 -0400

Although ink-jet (Sumitomo Chemical, Sumation, CDT, etc.), continuous spray (DuPont, Dainippon Screen), roll printing (LG Display, demonstrated for TFT backplanes), and roll-to-roll printing (GE) have gotten most of the attention, there is another, time-tested solution process: slot-coating or extrusion coating, which has been used to apply photoresist, among other things, for decades.

The OLLA project delivers its final milestone

oled — Thu, 19 Jun 2008 00:59:12 -0400

At the end of the project period, the OLLA project consortium presents its final milestone: the basic technology for a white OLED light source, with an efficacy of 50.7 lumens per watt at an initial brightness of 1.000 cd/m² based on the Novaled PIN OLED technology. The OLLA project is a joint basic research consortium, headed by Philips Lighting.

UDC - White OLED Technology Exceeds 100 lm/W

oled — Wed, 18 Jun 2008 01:43:51 -0400

Universal Display Corporation today announced that the company has successfully demonstrated a record-breaking white OLED with a power efficacy of 102 lumens per watt (lm/W) at 1000 cd/m2 using its proprietary, high-efficiency phosphorescent OLED technology.

Just last month at the Society for Information Display Symposium, Universal Display announced a new record of 72 lm/W. Since then, Universal Display has continued to make significant advances in this area – achieving yet another major milestone toward commercialization. The milestone also demonstrates the potential of white OLEDs to offer significant energy savings and environmental benefits to end users around the world. For the first time, white OLEDs have surpassed the power efficacy of the two incumbent indoor lighting technologies - incandescent bulbs are less than 15 lm/W and most fluorescent lamps are 60 - 90 lm/W.
