May 3, 2010... Novaled, an OLED maker and developer of Dresden, Germany, has demonstrated it OLEDs available on metal substrates such as steel or aluminum, at Light Plus Building in Frankfurt, Germany. Novaled has collaborated with Arcelor Mittal to develop OLED structures for steel substrates since 2006. In the German project Rollex since 2007, Novaled contributed to develop OLEDs on flexible aluminium substrates.

The company points out that such metal substrates offer excellent barrier properties and can be used in applications in which magnetic clipping of the OLEDs is intended or where soldering, drilling and similar assembly steps are required. Furthermore, Novaled notes that metal will also allow for bended or bendable OLED solutions. Metal substrates are also advantageous in application where heat dissipation is critical. Novaled contends that metal substrates may make it feasible at some point in the future to have low cost roll-to-roll mass production of OLEDs.

“Besides demonstrating excellent results with OLEDs on glass Novaled has developed a unique know how on OLEDs on metal," commented Gildas Sorin, CEO Novaled AG.

The OLEDs manufactured by Novaled for luminaires and light sculptures shown at Light + Building Frankfurt are processed directly on 0.7mm thick steel plates The metal substrate requires specific top emitting OLED structures. Novaled says it has developed a dedicated ITO free OLED architecture that it says has performances similar to standard bottom emission structures. In addition Novaled says it is developing thin film encapsulation which will enable bended OLEDs.
