June 26, 2006—Royal Philips Electronics and Novaled announced that in a joint research effort between Philips Lighting, Philips Research and Novaled, an unsurpassed record combination for efficiency and lifetime of high-brightness white OLEDs (Organic Light-Emitting Diodes) has been established.
Philips and Novaled reached a new record for the power efficiency of a white OLED, obtaining 32 lm/W with color coordinates of 0,47/0,45 and a CRI of 88 at a brightness of 1000 cd/m2. That same device structure thereby simultaneously shows a lifetime of more than 20,000 hours which is a major achievement for a future commercialization of the OLED technology for lighting applications.
OLEDs, unlike normal (inorganic) LEDs, incorporate organic materials in thin layers generating light emission when electrical power is applied. In contrast to LEDs, they are rather large-area sources with low brightness that emit diffuse light in any color. They can be easily structured to show patterns of color or homogeneous white light.
Royal Philips Electronics of the Netherlands [MOBINA: LINK TO: www.philips.com/newscenter ] is one of the world’s biggest electronics companies and Europe’s largest.
Novaled AG is engaged in the research, development and commercialization of organic light-emitting diode (OLED) technologies and proprietary materials.
