Abstract

Major achievements of this research project on rigid and flexible OLEDs are: lifetime enhancement by advanced constant luminance (L) operation, integration into textiles and furthermore, the prototype production on flexible PET/ITO substrates of polymer OLEDs. Our OLEDs were manufactured with spin-coating assisted by ink-jet printing. We introduced constant luminance operation (instead of the usual constant current) which was implemented in order to extend the overall lifetime of OLEDs. A threefold lifetime improvement was achieved by maintaining 50% luminance using an advanced microcontroller-based lifetime(LT) model. Various approaches to textile integration and evaluation of environmental issues in clothes (e.g. moisture) were investigated.
