Novaled (Dresden, Germany), a company that specializes in OLEDs for display and lighting applications, has been developing PIN OLEDs on metal substrates. OLEDs on metal can be used in applications where magnetic clipping of the OLEDs is intended, or where soldering, drilling and similar assembly steps are required. Furthermore, metal will also allow bended or bendable OLED solutions. OLEDs on metal are advantageous in application where heat dissipation is critical. In addition, metal substrates could allow low-cost, roll-to-roll mass OLED production.
Together with Arcelor Mittal, Novaled has been developing OLED structures for steel substrates since 2006. In the German project Rollex (roll-to-roll production of high efficient light-emitting diodes on flexible substrates), Novaled, since 2007, has developed OLEDs on flexible aluminum substrates.
Gildas Sorin, CEO Novaled AG, said, “With OLEDs on metal, Novaled is extending the range of lighting applications and solutions to specific market needs.”
The OLEDs manufactured by Novaled for luminaires and light sculptures shown at light+ building Frankfurt are processed directly on steel plates of 0.7mm thickness. The metal substrate requires specific, top-emitting OLED structures. Novaled has developed a dedicated, ITO-free OLED architecture that reaches performances similar to standard bottom emission structures, the company states. In addition Novaled is developing thin-film encapsulation, which will enable bended OLEDs.
