OLEDs for Lab on a Chip applications

Organic light-emitting diodes (OLED) have recently become one of the most promising techniques for future display and lighting applications. So far OLED are used in displays (mainly mobile applications up to now, active- and passively addressed for both flat panel displays (FPD) and microdisplays) and starting for lighting applications. However, in combination with film-based microelectronics they may also be seen as an enabler for a totally new class of optoelectronic devices, referred to as organic optoelectronic micro-systems. Nevertheless, there is a feature that can not be covered by those techniques: inherently high efficient light generation.

Considering biotechnology applications beside different types of detectors there are also various actuators applied. Photodiodes perform CMOS-inherent photodetectors and thus full CMOS process compatibility, OLED act as illumination for fluorescence. So far there is no commercial technology available that provides highly-efficient and stable light sources in CMOS. Progresses have been made by introducing small molecules on OLED to increase efficiency. In fact a colourimetric device with a OLED has been fabricated by FhG IPM. This approach will be implemented in the Skin Patch applications substituting the CMOS photodetector by a OPD (Organic photodetector) on SU8.

The right balance between relevant, feasible and efficient research.
