It turns out to be extremely easy to use!
When I tried to rip off that broken screen off the metal plate, it broke completely. The front plastic peeled off, with the most of the woodoo stuff that makes the thing work stuck to it.
I can draw on it with bare fingers. All I need is a power supply, 12V in my case. The current flows through me, via the finger, then via the woodoo stuff, into the transparent conductive coating on the plastic film.
Depending on the polarity, I can draw with black, or white, The inverse is happening on the other side.
Nice fingerprint scanner device that E-ink is!
