We are always looking for ways to innovate and develop new application fields that add value to our steel products. We consider OLEDs to be very promising says Michel Beguin, General Manager of ArcelorMittals Industry Research Centre in Liège, Belgium.
According to Beguin, the Novaled technology gives the advantage of an efficient top-inverted structure that is well adapted to metal substrates.
Using steel plates as substrates, remarkable properties can be achieved for bendable OLED applications. Compared with standard glass-sheets, metallic substrates offer several advantages; they are more robust and durable, and are commonly produced by roll-to-roll process. This production Method can be adapted to a subsequent in-line process for OLED deposition enabling high throughput manufacturing with low tact time.
Novaled expects to contribute to the project its broad technical experience with respect to highly efficient and stable OLED device architectures, as well as its material know-how for doped transport layers.
RGB OLEDs have been processed directly on classical OLEDs. The striking results showed that the Novaled technology enables standard steel foil acting as reflective bottom electrode says Jan Blochwitz-Nimoth, CTO of Novaled. We are very pleased to support ArcelorMittal in its OLED developments on Metal plates.
An optical fiber cable is a cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. Different types of cable are used for different applications, for example long distance telecommunication, or providing a high-speed data connection between different parts of a building.
Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide. This coating protects the fiber from damage but does not contribute to its optical waveguide properties. Individual coated fibers (or fibers formed into ribbons or bundles) then have a tough resin buffer layer and/or core tube(s) extruded around them to form the cable core. Several layers of protective sheathing, depending on the application, are added to form the cable. Rigid fiber assemblies sometimes put light-absorbing ("dark") glass between the fibers, to prevent light that leaks out of one fiber from entering another. This reduces cross-talk between the fibers, or reduces flare in fiber bundle imaging applications.
