Fraunhofer IPMS offers customer/application-specific developments based on highly efficient OLEDs in combination with the novel fabrication technology based on the world-wide first vertical In-line fabrication system for organic light emitting diodes.
Especially for OLED light sources the cost pressure on the fabrication is enormous. The Fraunhofer IPMS will show on the fair the first time a novel fabrication combination to achieve low cost fabrication for lighting applications. One important aspect for fabrication cost is the used ground contact, which is commonly build by the use of ITO, a widely used contact material for LCD displays. Due to grow of display fabrication the cost for ITO increases drastically over the past 3 years by a factor of three. For low cost fabrication a low cost alternative for ITO have to be used. The Fraunhofer IPMS makes investigations, inside of the European largest OLED lighting project named OLLA (High brightness OLEDs for ICT & Next Generation Lighting Applications), to replace ITO by a new low cost material named ZAO (Aluminium doped ZnO) . Large area highly efficient OLEDs on this low cost anode material will be shown on the fair.
