Arcelor Mittal, the world's largest quality steel maker, and Novaled, OLED technology and material provider, have joined forces for a new OLED project. The partners are developing top-emitting OLEDs on flexible substrates for signage and lighting purposes since 2006.

By using Arcelor Mittal's steel plates as substrates, remarkable properties for bendable OLED applications can be achieved. Metallic substrates offer several advantages. Compared to standard glass-sheets they are more robust and durable and commonly produced by roll-to-roll process. This production method can be adapted to a subsequent inline process for OLED-deposition enabling high through-put manufacturing with low tact time. In this collaboration Novaled contributes both 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.
