What if tattoos like this could become a reality? That’s only one possible application of super thin wearable displays.
Researchers at the University of Tokyo have developed something called an “optoelectronic skin” with polymer LEDs and organic photodetectors that are only 3 micrometers thick! You could have a watch effectively tattoo’d right there onto your hand, which is more effective and useful than the one I drew onto my wrist with a Sharpie, just now, out of boredom.
The tech isn’t quite there yet obviously. It has to be held in place with clingfilm and the display is just a single-digit field that displays your blood oxygen levels. However, it’s easy to imagine all of the applications that advanced wearable displays could have in the future.
Check out a video of the display in action below.
