Solution-processable organic light emitting diode on glass fibers for textile applications — •Björn Gruber, Schulze Kerstin, and Janietz Silvia — Fraunhofer Institute for Applied Polymer Research, Geiselbergstr. 69, 14476 Potsdam-Golm, Germany

Electronic devices based on organic materials offers the possibility to be a low-cost production technology on large area in several years. As a special application organic devices could be used in the field of electronic-textiles in future, for example for safety applications or as smart textiles. Therefore the direct integration of the electronic devices on the textile fibers is interesting.

In this work, organic light emitting diodes (OLEDs) have been manufactured and investigated on cylindrical and flexible substrates. Especially the cylindrical geometry of the substrate hinders a homogeneous deposition of organic layers. Here, we present first results using solution processes for the preparation of the organic materials of an organic light emitting diode on glass fibers. The OLEDs were prepared on thin glass fibers using thermally evaporated metals and dip-coated polymeric layers. We focus on the challenging preparation steps of these layers on cylindrical substrates resulting in working devices. Additionally a current density-voltage-characteristic of a light emitting device on a glass fiber is presented and analyzed.
