Fraunhofer IPMS to show OLED-on-CMOS ICs at Smart Systems Integration
Silicon and CMOS integrated circuits are the base for almost any product. For optoelectronic applications, silicon has the advantage that it can also be used for sensing the incoming light and converting it into electrical signals, at least for the visible range. However, there is one drawback: silicon is not capable to emit light. Hence, typically hybrid integration of a light emitter together with a sensing and processing IC is necessary, which leads to costly solutions. This has recently been overcome by the integration of Organic Light Emitting Diodes (OLEDs) into CMOS ICs, a technology also known as OLED-on-CMOS and presented at Smart Systems Integration 2010. Applications for OLED-on-CMOS are many fold. Typical sensors applications are reflex light barriers, flow sensors by determining the velocity of particles within the fluid and color sensors, the latter made possible by integration of OLEDs in various colors. More complex devices are OLED microdisplays with diameters of about half an inch, but pixel count comparable to large screen displays. They can be used both in Head Mounted Display applications and for ultra compact projection systems, both system architectures suited for new products in consumer electronics. Fraunhofer IPMS supports these developments by complete system solutions like the so called Mediabox which converts wireless TV (DVB-H, DVB-T) and data received via WLAN into signals suited for the OLED micro displays. It will be shown at our booth at the Smart Systems Integration 2010. In addition, one can realize micro-scale optical emitters and receivers on the same chip in an array type organization. This Bidirectional Microdisplay presents and captures images at the same time. Fraunhofer IPMS will show latest demonstrators featuring this technology at the booth at Smart Systems Integration 2010 as well.
Michael Scholles, Business Unit Manager at Fraunhofer IPMS, will present the technical background of those developments in his talk titled "Integration of Organic Light Emitting Diodes into CMOS circuits for smart optoelectronic systems", to be held on Wednesday, March 24th at 10:25 am.
