October 20, 2007 – Vol.12 No.30 ArcelorMittal and Novaled Join Forces in OLED Development. The world’s largest steel maker and OLED (Organic Light Emitting Diode) technology and material provider are developing top-emitting OLEDs on flexible steel substrates for signage and lighting purposes. In the partnership Novaled contributes both its technical experience in efficient and stable OLED device architectures as well as its material know-how for doped transport layers of OLEDs. By using ArcelorMittal’s steel plates as substrates bendable OLED applications can be achieved. Metallic substrates offer several advantages compared to standard glass-sheets. They are more robust and durable and can be produced by roll-to-roll process. Novaled technology enables standard steel foil to act as as a reflective bottom electrode. OLEDs incorporate organic materials in thin layers generating light emission when electrical power is applied. OLEDs are generally large-area light sources with low brightness that emit diffuse light in any color, patterns of color or homogeneous white light. OLEDs offer the potential to become even more efficient as energy-saving bulbs. Once efficient OLEDs are available at mass production costs, they can be used for many applications in lighting. Novaled AG is engaged in the research, development and commercialization of organic light-emitting diode (OLED) technologies and proprietary materials. ArcelorMittal is the world's number one steel company, with 320,000 employees in more than 60 countries. (10/16/07)
