Microdisplays based on OLEDs for multimedia applications like video and data display could be available within a couple of years according to Fraunhofer IPMS.

 

For the first time ever, OLEDs offer the possibility to integrate highly efficient light sources with photo detectors on a CMOS backplane. This enables fully integrated optoelectronic applications based on silicon, which allows micro-scale optical emitters and receivers on the same chip, providing a device that presents and captures images at the same time.

 

This could be the foundation for a new class of device for personalized information management that presents information to the user, and at the same time optically recognizes a command by the user.
