Fraunhover demonstrates OLED data eyeglasses using a bidirectional microdisplay

April 13, 2010
Date Announced: 13 Apr 2010 Fraunhofer IPMS offers a very unique technology to its customers: the integration of Organic Light Emitting Diodes (OLEDs) as highly efficient light source into standard CMOS Integrated Circuits. This allows fully integrated optoelectronic solutions and applications on silicon. One very innovative component that could be realized for the first time using this technology is the so called Bidirectional Microdisplay of Fraunhofer IPMS, i.e. an element that displays an image and acts as a camera at the same time by interleaving display pixels and photo detectors in a mosaic style. A fully functional demonstrator based on this component is shown at SID DisplayWeek 2010 for the first time. By integration into a specialized optics which is mounted at some sort of eyeglasses that still allow the perception of the natural environment, additional optical information will be provided using the information system (Augmented Reality). The integrated camera looks at the eye and records any change in the position of the eyeball. A subsequent image processing can distinguish between unconscious movements and the ones the user does by intent. The overall system can modify the content that is shown on the display according to the eye movements. Hence, the user can control the presented information just with movement or actions of the eyes, without using the hands or spoken commands. This fully functional feedback loop will be presented by Fraunhofer IPMS at SID DisplayWeek 2010 for the first time ever.
