Visitors to the OSRAM Opto Semiconductors Booth #215 at the CEDIA Electronic Lifestyles® EXPO in Las Vegas, April 20-21, will be able to not only imagine, but actually experience what a home of the future could be like with several installations of its latest OLED products.

OSRAM Opto Semiconductors will debut several new Pictiva™ OLED products at the CEDIA Electronic Lifestyles EXPO including: The Calgary 2.7-inch 128x64 dot display, the Miami 5-inch 384x128 dot display, and the Zurich 6.5-inch 256x32 dot display.

OSRAM and Philips have signed a patent crosslicense agreement covering optoelectronic semiconductors. The agreement involves the mutual licensing of patents for all inorganic and organic LED.

The agreement relates to patents held by Philips, including the US subsidiary Lumileds, and by OSRAM including its subsidiary OSRAM Opto Semiconductors.

OSRAM Opto Semiconductors announced a new reference design kit for their 2.7" 128x64 PMOLED panel. The Reference Design Kit serves as a design model and helps customers to easily evaluate OSRAM OLED products, allowing for rapid and efficient integration into their display system applications.

The kit includes all necessary items to power up, initialize, test various modes, and display images on a display module. The kit is already shipping for less than $200.

Aixtron is to take part in the OPAL 2008 (Organic Phosphorescent lights for Applications in the Lighting market 2008) R&D project in a consortium with Osram, Philips, BASF and Applied Materials. The project will use Aixtron's Organic Vapor Phase Deposition (OVPD) technology platform.

OPAL 2008's aim is to develop OLED production technology capable of achieving a target cost of a few Euro cent per cm² for a high performance white OLED device, with the ultimate goal of introducing the new lighting technology into the market.

Osram said it would concentrate its research and development work on organic light emitting diodes (OLEDs) with the aim of applying this technology also to general illumination.

Osram said it would continue to develop polymer-based solutions for displays but also focus on small-molecule technology for illumination applications. OLEDs are set to be used as extremely thin light sources with large surface areas, for signage and information systems and may even one day be used as illuminated wallpaper, Osram said. The planned work focuses on the design and implementation of specific device architectures for OLEDs, on increasing their efficiency and lifespan and on scaling up to large areas. Experts are also involved in creating the right conditions for high-volume production.

Osram Opto Semiconductors has announced progress on its OLED Lighting project. The project, funded by a $4.65 million grant from the US Department of Energy, was initiated in 2004 to research the potential of white OLEDs as an energy-saving product for commercial and residential lighting.

The company has achieved a 25-lm/W polymer OLED. The cool-white-emitting diode uses a solution-processable, phosphorescent, blue-emitting device in conjunction with an external inorganic phosphor layer. This 14 lm/W of blue color was achieved by embedding an efficient phosphorescent blue emitter in a polymer host.

The company has also demonstrated a 20-lm/W phosphorescent device based on a white-emitting polymer blend. This diode employs no external phosphors, and the white emission comes directly from the phosphorescent polymer. The company hopes to use the advances as a basis to develop large-area light tiles.

The polymer OLED enables color tuning, using a design based on three separate, printable polymer inks emitting in the red, green and blue portions of the spectrum. Ink-jet was used to pattern the small, three-color segments. The product’s driver circuitry enables users to regulate color from dark blue to white. The technology offers large-size scalability without losses in optical and electrical properties.

Anders Electronics has added a 2.7" PMOLED module to its range of low-profile, low-power video-capable displays, presenting an easy upgrade path from LCD modules that are thicker and heavier and also require a backlight. A quick start guide and rapid evaluation hardware are also available from Anders Electronics, for fast and easy system-level integration of OLEDs in a wide range of sizes and resolutions including the new 2.7in module. The new Osram Pictiva 2.7" OLEDs are 128 columns x 64 rows resolution, enabling clear display of text or graphic images.

Yellow or green versions are available, each having 4bit grey-scale colour depth. Offering the established benefits of OLED technology, the new modules have 180 degree viewing angle and 2000:1 contrast ratio for excellent readability in a wide range of situations in audio products, industrial equipment or medical instruments. The latest 2.7" displays are only 3.4mm thick, for easy mounting in very thin panels, and consume 0.05mW in sleep mode.

OSRAM Opto Semiconductors today announced the newest addition to its Pictiva(TM) line of OLED graphic display products. The company's new 2.7-inch, 128x64 dot display is the company's solution to offering a lifetime of 55,000 hours.

In addition to an ultra-wide, 180-degree viewing angle, 2000:1 contrast ratio, rapid video response capabilities and a thin profile, the new 128x64 pixel graphics Pictiva display is an industry-standard 2.7 inches, enabling excellent readability and presentation of graphic and text images. Pricing for the Pictiva OLED display is comparable with LCD screens, yet Pictiva OLED displays offer increased performance, enhanced features and a long life.

OSRAM's new 128x64, 2.7-inch Pictiva OLED display is currently available for $19.50 in 1,000-unit quantities.

The OSRAM Pictiva Reference Design Kit from Anders Electronics provides a turnkey hardware platform that allows designers to quickly power up, initialise, test various modes, and display images on the on-board OLED module via a host desktop or laptop PC. A user friendly PC interface is also provided, supporting useful functions including contrast level adjustment and gamma tables.

The board includes a 128 x 64 pixels OSRAM Pictiva OLED display, 8051 microcontroller and on-board serial flash memory, enabling designers to quickly begin developing software. The kit also includes GUI reference design and graphics generation source code for firmware, plus necessary cables and comprehensive documentation. Electronic documents provided include driver data sheets, users manual and seven application notes guiding designers through OLED driver register setup, communication protocols, power, image and lifetime optimisation, plus further essential knowledge to complete an OLED design. Schematics, gerber files and bill of materials are also included, to speed up hardware development.

The 128 x 64 pixels OLED display provided on board the Pictiva development kit has 100 nits luminance, 160° viewing angle, 100:1 contrast ratio, and operating temperature range -30° to 70° C.

A wide range of similar OLED display modules are also available from Anders Electronics, in popular display formats including 80x48, 96x36, 96x64 and 128x48, as well as 128x64.

OSRAM Opto Semiconductors today announced the latest achievements in its white OLED project, funded by a $4.65 million grant from the U.S. Department of Energy (DOE). The 2004 DOE grant was issued to research the potential of white OLEDs to save energy in commercial and residential lighting applications. OSRAM's most recent milestone provides a breakthrough in polymer-OLED technology by achieving a record 25 lumens-per-watt (lm/W) of device efficiency.

The company also announced it has developed the first polymer-OLED, "tunable" light source, enabling color tuning and true illumination-design freedom.
"We are very excited to announce our latest DOE achievements. These milestones directly support the DOE's objectives by demonstrating polymer-OLED potential in lighting applications," said Dr. Alfred Felder, OLED Business Unit Head, OSRAM Opto Semiconductors. "By exploring polymer-OLED technology for solid-state lighting applications, we have created a powerful, innovative and desirable solution with confirmed compatibility and scalability over large areas."
