During the Photonics West 2009 the Fraunhofer IPMS will present the prototype of a bi-directional OLED microdisplay with an imaging CMOS photo diode matrix interlaced in a QVGA display (12 x 9 mm²), both are integrated and work at the CMOS chip.
Furthermore, an optical flux sensor will be presented, which includes the required light source on the CMOS-sensor chip. A CMOS photo diode line allows the detection of the speed of a particle flow and an embedded OLED light source in the form of stripes in parallel to the photo diode line provides the illumination of the medium.
Due to the achieved reduction of the expenditure regarding the construction and circuit technology numerous applications of those devices are enabled. Fields of application vary from chemistry, medicine to life science. Other applications of OLED-on-CMOS include light barriers, opto-couplers and optical communications.
