OLED lighting elements are recognized as light emitting graphical elements. They can be shaped, patterned or inscribed in a plethora of ways. The possible feature diversity of OLEDs is highly attractive for the creative industry. With its outstanding key feature to provide high-quality glare-free area light with crisp light colors, as well as its flexibility and low weight, OLED technology is ideally suited for the use in fashion items like garments or accessories and other near body applications.

Fraunhofer FEP is providing a standard OLED layout as a basis for integration of area light into textiles and garments utilizing OLED technology. The OBUTTON is a tiny circular module that is equipped with a shatterproof plastic-foil-based OLED lighting element on a rigid printed circuit board, which ensures the electrical control of the OLED. This enables designers and makers to get in touch with OLED lighting technology. The OBUTTON is an easy-to-integrate OLED lighting element, that enables electrical and mechanical textile assembly via conductive yarn on the one hand and demonstrates the processability, behaviour and aesthetics of a common button on the other.
