ABSTRACT:
A flat or sheet-like electrooptical component for sending and receiving electrical and optical signals includes a central emission region with at least one light-emitting device for sending out optical signals. A sensor region is arranged around the emission region, and at least one device for sensing optical signals is configured in the sensor region. A reflector region is arranged around the sensor region for reflecting incident electromagnetic radiation. The electrooptical component also includes a device for driving the light-emitting device based on incoming electrical signals, and a device for outputting electrical signals based on received optical signals.
