Using OLEDs in an interesting way
Dresden based Fraunhofer FEP (pvt) has developed a unique application for OLED microdisplays. The company has adapted an OLED microdisplay, built on a silicon substrate, to read fingerprints without additional optics. The sensor both emits light that reflects off of the finger, and detects that light allowing for analysis. The resolution of the sensor is 1600 dpi, which is 3x the required FBI resolution, and allows for the identification of very small sweat holes (What does your sweat hole pattern look like?) for more detail than is currently available.
The company expects the system to be adopted for mobile devices as the additional resolution will make it less susceptible to ‘spoofing’, and will be shown at the upcoming 2017 SID Display Week conference. Just remember they can still cut your finger off and use it to gain access to your secret lair, unless your sweat holes have dried up and closed after digit removal….
