The concept multimedia viewer Toshiba’s showing off at IFA is nice and all with that 1.8-inch drive and WiFi, Bluetooth, and SD, don’t get us wrong. But what we’re really feeling is that someone’s finally really starting to get some proper OLED displays out there. The Toshiba’s got a 3.5-inch 320 x 240 screen, which can apparently be tilted from the base. 

Not too shabby at all, but we’re not sure how much longer we can patiently wait for these low-power vibrant-color displays to hit the streets in force.

OLED company Novaled GmbH has developed a red top emission OLED that produces 10 lumens per watt at 500 candelas per square meter, with a projected lifetime of more than 100,000 hours.

According to Novaled, the OLED achieves a breakthrough by combining the highest power efficiency and longest lifetime for a top emission OLED, using transport layer doping technology. The part uses a red phosphorescent emitter from Covian Organic Semiconductors GmbH with molecular dopant materials from Novaled.

Universal Display Corporation the Company that's lighting the way in developing and commercializing OLED technology for displays, lighting and other opto-electronics, announced today that it has been awarded a nine-month, $98,894 Small Business Innovation Research (SBIR) Phase I contract by the U.S. Department of Energy (DOE). The goal of this new program is to demonstrate an innovative approach to increase the brightness and power efficiency of white OLED lighting using Universal Display’s proprietary PHOLED™ phosphorescent OLED and OVPD Organic Vapor Phase Deposition technologies.

In this program entitled, High Efficiency White Mesh Phosphorescent OLEDs, the Company will work to increase OLED efficiency and brightness by employing novel emissive layer architectures that are enabled through the use of its proprietary OVPD process technology.

Univeral Display announced a new 6x6 inch white OLED panel that features 30 lm/W - which is the world's most efficient OLED lighting panel to date. UDC's new panel is based on a design that consists of an array of red, green and blue colored stripes. These panels are tunable (by changing the intensity of each primary color).

The 30 lm/W white OLED panel can emit color temperatures between 2900 and 5700 K. The 30 lm/W was achieved at a color temperature of 4000K (like a cool fluorescent lamp). The panel also featured acolor index of over 80 CRI.

Cambridge Display Technology, which is helping MicroEmissive Displays (MED) to overcome its manufacturing problems, is confident that MED will resolve its issues satisfactorily.

"CDT and MED are closely collaborating," Dr S B Cha, CDT’s commercial v-p, told Electronics Weekly. "We are more than just a licensing company we are a research services company. All of our licensees find you start manufacturing at a low level, and then find the technological advances which give you increases in yield," he said.

Merck KGaA may start selling OLED Lighting products by the end of this year, Edgar Boehm, head of Merck's OLED business told the Financial Times Deutschland.

'Our internal plans call for us to start selling the first commercial products by the end of this year,' Boehm told the newspaper.

However, Merck has no set deadline for launching its OLED sales, and representatives at the company's German headquarters said the new products may not reach the market this year.

Universal Display Corporation announced a fundamental technical achievement in the development of its blue PHOLED phosphorescent OLED technology: a sky blue PHOLED with over 15,000 hours of operating lifetime. This is the first blue PHOLED which has broken through, by an order of magnitude, the 1,000 hour lifetime barrier - a challenge that some people thought might be insurmountable. The announcement was made today at Universal Display's annual shareholders' meeting, held in Philadelphia, PA.

The Company's proprietary blue PHOLED demonstrates a lifetime that exceeds 15,000 hours at 200 cd/m2, and also offers excellent efficiency, a trait for which the Company's PHOLED technology is renowned, with 9.5% external quantum efficiency and 22 cd/A luminous efficiency. With CIE coordinates of (0.16, 0.37) and a 474 nm peak emission wavelength, which is equivalent to a sky blue color, this material system is not yet saturated enough for commercial full-color applications.

Earlier this year, Universal Display had disclosed a deep blue PHOLED. The Company is now continuing its research efforts to unify the deep blue color, efficiency and lifetime in one system to meet the needs of the commercial OLED market.

Luxell Technologies announced today that the Company has received, from the Government of Canada, an investment commitment for up to $1.95 million for the research and development of flat panel display technology for the aerospace and defence industry. This Technology Partnerships Canada (TPC) investment is part of a $6.5 million project being undertaken by Luxell Technologies Inc.

The three key desired outcomes of this project include the development of a tool-kit that allows flat panel display components to be cost-effectively adapted for use in the harshest environments; an Active Matrix Liquid Crystal Display (AMLCD) process that permits re-configuration of components and alleviates obsolescence issues; and an Organic Light-Emitting Diode (OLED) process that enables use in the harshest of environments.

Luxell Technologies announced today that, as part of the ongoing business and technical partnership between the two companies, Hyundai LCD recently delivered to Luxell a prototype Enhanced Contrast Ratio (ECR) Organic Light Emitting Diode (OLED) display incorporating Luxell's patented Black Layer(TM) contrast enhancement technology. This prototype is the first of its kind, and was manufactured on Hyundai's Small Molecule OLED pilot production line.

The device, having a 1.5" display, is the world's first full colour passive matrix OLED display featuring Black Layer(TM) technology produced in a cell-phone capable format and capable of displaying text, graphics and full motion video. Technical details of the visual performance parameters of the device and the manufacturing process used will be disclosed at the 2005 International Meeting on Information Display (IMID'05) in Seoul, Korea, July 19-23, 2005.

Cambridge Display Technology has reached an agreement with IBM Corp. to market IBM's advanced amorphous silicon (a-Si) thin-film-transistor (TFT) technology for organic-light-emitting-diode (OLED) displays.

CDT will market IBM's IP in TFT devices, pixel circuitry, drive methods, and active-matrix OLED display modeling for display applications. IBM will manage technology licensing agreements.
