Novaled Intensifies Development of Top Emitting OLEDs.DRESDEN, Germany -- Novaled has achieved groundbreaking results in lifetime, voltage and efficiency of top emitting RGB (Red Green Blue) The computer's native color space, which is the color system for capturing and displaying images. RGB was derived from our own perception of color because human eyes are sensitive to red, green and blue (see trichromaticity). stacks with its PIN OLED (Organic Light Emitting Device, Organic Light Emitting Diode) A thin film light-emitting technology that is expected to compete with LCD and plasma TVs as well as LCD monitors and readouts. technology. Lifetimes for blue OLEDs are up to 16,000 hours, for red and green up to 100,000 hours at an initial brightness of 500 cd/sqm. This latest performance means that green OLED devices are now outperforming their bottom emission reference samples by a factor of 2.5. White top emission devices achieved a lifetime of 18,000 hours at a driving voltage of 3 V and a starting luminance The amount of brightness, measured in lumens, that is given off by a pixel or area on a screen. For example, dark red and bright red would have the same chrominance, but a different luminance. of 1,000 cd/sqm. The lowest ever reported operating voltage has been realised for green top emission OLED stacks of 2.5 V at 1,000 cd/sqm. At 95 cd/A, the current efficiency is even higher than for comparable bottom emission devices. These green devices are based on standard emitter material Ir(ppy)3. Top emission OLED structures emitting light away from the substrate are a key feature of future OLED applications. The top emission type increases the aperture ratio above 50% for displays and paves the way for more powerful, large area active-matrix displays. When used in lighting devices, top emission OLEDs enable manufacturers to use cheap non-transparent and flexible substrates. "Top emission OLEDs are the future of display and lighting applications. With the latest results and performances of its PIN OLED structure, Novaled has confirmed its status as being the best partner for OLED makers" says Jan Blochwitz-Nimoth, CTO (Chief Technical Officer) The executive responsible for the technical direction of an organization. See CIO and salary survey. of Novaled. "Our technology is currently being tested by different OLED manufacturing companies preparing their entry into mass production." About Novaled Novaled AG is engaged in the research, development and commercialization of organic light-emitting diode Noun 1. organic light-emitting diode - a self-luminous diode (it glows when an electrical field is applied to the electrodes) that does not require backlighting or diffusers OLED (OLED) technologies and proprietary materials. The company is a spin-off The situation that arises when a parent corporation organizes a subsidiary corporation, to which it transfers a portion of its assets in exchange for all of the subsidiary's capital stock, which is subsequently transferred to the parent corporation's shareholders. from the University of Dresden and the Fraunhofer-Gesellschaft. Main investors include Credit Agricole Private Equity, TechnoStart, TechFund Capital Europe and CDC See Control Data, century date change and Back Orifice. CDC - Control Data Corporation Entreprises Innovation. Founded in 2001, Novaled experienced rapid growth, maturing into a world-class company. The enterprise commercializes its Novaled PIN OLED(TM) technology along with its proprietary OLED materials to display makers and lighting companies. The company has a strong IP position in OLED technology based on more than 220 patents granted or pending. www.novaled.com About OLEDs OLEDs are semiconductors made from thin layers of organic material only a few nanometers thick, which emit light. In a fast growing market OLEDs are key parts of a revolution: the dream of paper-thin, flexible, highly efficient displays with brilliant colours and high contrast is becoming reality. OLEDs represent the future of ultra flat panel displays A thin display screen for computer and TV usage. The first flat panels appeared on laptop computers in the mid-1980s, and the LCD technology became the standard. Stand-alone LCD screens became available for desktop computers in the mid-1990s and exceeded sales of CRTs for the first time as well as a vast array of new lighting applications. |
