Step closer to better security

Benefit from OLED-on-silicon technology: enables the high-precision integration of an OLED as a light source on a microchip. An object can be lighted up and reflected light together with sensor generate needed information. Thanks to Fraunhofer FEP that has top experiences with utilizing this technology created the first prototype that has a native resolution of 1600 dpi – this is three times more than typically required by the FBI.
Verification in our mobile phone and much more…can you think of your applications that could also benefit from this technology?
