Novaled Achieving Groundbreaking Lifetimes For PIN OLEDs.DRESDEN, Germany -- Novaled has achieved outstanding results in lifetime for both, top and bottom emission PIN OLEDs. More than one million hours at an initial brightness of 1,000 cd/sqm have been reached. Novaled achieved unsurpassed lifetime results for top and bottom emitting red fluorescent devices. A red bottom emitting Novaled 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. (TM) shows a 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. drop of only 4% after 6000 hours measurement at a starting brightness of 3,700 cd/sqm. The record top emitting red PIN OLED shows a luminance drop of even only 1% after 1,000 hours measurement at a starting brightness of 12,000 cd/sqm. Both OLEDs are down calculated to more than one million hours (corresponding to one century) at starting brightness of 1,000 cd/sqm. Novaled has also reached significant achievements for blue fluorescent PIN OLEDs: 50,000 hours at 500 cd/sqm in bottom emission answering the request of 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). Active Matrix displays (hardware) active matrix display - A type of liquid crystal display where each display element (each pixel) includes an active component such as a transistor to maintain its state between scans. Contrast passive matrix display. . In addition, major lifetime improvements have been shown for green phosphorescent phos·pho·res·cence n. 1. Persistent emission of light following exposure to and removal of incident radiation. 2. Emission of light without burning or by very slow burning without appreciable heat, as from the slow oxidation of PIN OLEDs (100,000 hours at 500 cd/sqm for Ir(ppy)3 based top emission OLEDs). With this value Novaled has doubled its performance for Ir(ppy)3 based green OLED stacks during the last twelve months. "We are confident to reach one million hours lifetime with more performing phosphorescent emitting material", says Jan Blochwitz-Nimoth, CTO (Chief Technical Officer) The executive responsible for the technical direction of an organization.

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 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 colors and high contrast is becoming reality. OLEDs represent the future of ultra flat panel displays as well as a vast array of new lighting applications. |
