Following quickly behind the recent announcement of rapid progress in the development of longer lifetime blue light emitting polymers, comes this announcement of similarly impressive progress on red materials.

Data from devices produced using these latest, solution processable, phosphorescent materials show lifetime of 98,900 hours from an initial luminance of 400 cd/m², equivalent to over 1.5 million hours from 100 cd/m².

The FY 2007 Department of Defense Appropriations Bill includes two priority projects sought by eMagin Corporation and the U.S. Army. eMagin will conduct two technology development efforts to support projected military needs. The first aims to improve the power-efficiency of OLED microdisplays for U.S. Army thermal imaging applications; the second will result in a very high-resolution, HD-compatible display for U.S. Army medical applications.

The bill has budgeted $2.75 million to support the two projects for fiscal year 2007. The projects will involve design and engineering resources in both New York and Washington.

LG.Philips LCD said yesterday that it has developed the world’s slimmest LCD panel for mobile phones at 1.3 millimeters thick, which it claims to be thinner than Samsung’s OLED. A few hours later, Samsung SDI refuted the claim in a press release, saying it already possesses 0.8-millimeter technology for OLED.

Samsung SDI, the global rival of LG.Philips in the small-size display market, played down the technology, saying its OLED products are much superior in quality than LG.Philips’ LCD panels.

Universal Display Corporation today announced significant advances in the development of P(2)OLEDs printable, phosphorescent OLEDs as part of an ongoing joint development program with Seiko Epson Corporation. The demonstration of P(2)OLED materials that possess the high-efficiency of Universal Display's PHOLED phosphorescent technology, as well as ink-jet printing potential, is an important step toward the realization of cost-effective, large-area OLED displays. OLED displays are currently used in cell phones, MP3 players and PDAs, and are widely recognized as a strong candidate for use in the next generation of flat screen televisions.

After working together for less than two years, Universal Display is reporting key achievements in the development of a P(2)OLED system based on solution-processable, small-molecule PHOLED materials. These results include significant lifetime and efficiency advances for red and green color emitters.

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.

With the Joint Innovation Lab (JIL) BASF is opening a research laboratory for organic electronics in Ludwigshafen on September 11. BASF will conduct research at the JIL with both industrial and academic partners into new materials in the field of organic electronics.

At present the JIL researchers are concentrating on organic light emitting diodes (OLED) and organic photovoltaics. OLEDs are flat, thin light-emitting devices made from organic semiconductive materials. As lighting panels, they offer completely new options in lighting technology, such as windows as transparent light sources or credit card sized flashlights. The researchers have calculated that in their current form OLEDs are likely to consume less than half as much power as conventional fluorescent tubes. OLEDs also have a long lifetime.

In this area, BASF Future Business GmbH has launched the project "OLEDs for appliances in the lighting market" (OPAL) together with partners from industry such as OSRAM, Philips, Aixtron AG and Applied Materials. The goal of the project is to create the scientific and technological basis for initiating the production of OLED-based lighting in Germany.

Cambridge Display Technology and Sumation announce rapid progress in the development of longer lifetime blue light emitting polymers suitable for full color, video capable PLED displays.

The latest data show a lifetime of 20,000 hours from an initial luminance of 400 cd/m², equivalent to over 320,000 hours from 100 cd/m². This represents a three-fold improvement over the lifetime announced a year ago, and demonstrates the fruits of the collaboration by the development teams and the strong focus on this area. It is believed that there is great potential to make further dramatic improvements.

OLED-T today unveiled its patented electron injector EEI-101. EEI-101 is suitable for use with fluorescent or phosphorescent red, green and blue OLEDs and reduces OLED manufacturing costs thanks to its low temperature deposition using vacuum coating methods. The lower deposition temperature also reduces any potential damage to the underlying organic layers, thereby improving the lifetime of the OLED device.

Available in kilogram quantities, EEI-101 is provided in a powder form which can be deposited onto any desired substrate by vacuum coating methods.

Leadis Technology today announced sample availability of the LDS522, a 65K color OLED driver IC. The LDS522 65k color OLED driver IC is a highly-integrated high-performance device with integrated display RAM, on-chip oscillator, DC/DC converter, and temperature sensor to insure optimal visual performance.

In addition, the LDS522 includes programmable display features such as area scrolling, partial display, and color depth selection for enhanced screen performance.

Samsung SDI presented 4.3-inch WQVGA AMOLED at IMID 2006, using SGS (Super Grain Silicon) Technology. This technology enables manufacturers to produce large-size AMOLED.

A researcher at the company said that it is possible to reduce production cost by using LTPS technology that doesn't use laser, thereby strengthening competitiveness of AMOLED better than TFT-LCD.
