Polymer materials for display technology

Polymer materials are well known in modern microelectronics. In the past, however, they have been used mainly for passive materials, substrate and encapsulating materials and adhesives. Special polymers with conjugated units have been employed as functional materials for the last decade. The first displays based on organic light-emitting diodes (OLEDs) have been on the market for a short time and the development of flexible OLEDs with a long lifetime is the proclaimed aim of many research institutes and companies. The Fraunhofer IAP is working on the development of new polymer materials and device technologies in this research area.
