Andreas Dahlin and grad student Kunli Xiong, of Chalmers University of Technology in Sweden, created the material while investigating combining conductive polymers with nanostructures. The tiny cells — plasmonic metasurfaces, you know — can be turned on and off with a tiny change in voltage, like an LCD subpixel. But like other reflective displays (and indeed regular paper), it doesn't actually emit any light.
[...] By changing the makeup of the... plasmonic metasurface, the color it reflects can be adjusted, and so by putting them in formation — red, green, and blue — the display can produce the usual variety of in-between colors.
Previous color e-paper displays have generally had a sort of washed-out look, and it's hard to say whether this technology would avoid that trap. Dahlin is aware of it, however, and said they're working on achieving the deepest colors they can. The refresh rate would only be a few times per second, but the resolution is potentially far greater than either LCD or existing e-paper. "We have not tested the resolution limit but it would definitely be high enough for any display, perhaps a few micrometers per pixel (10^4 dpi), which is much smaller than the human eye can resolve," Dahlin told TechCrunch in an email.

Amazon Kindle does most of what makes e-paper useful. It just doesn't bend or have color.

What no one seems to do is make an epaper tablet that runs a regular GNU/Linux system. Yes, some of the older Kobo systems could be booted from a user-provided SD card, but there was no documentation for the proprietary device drivers, so it wasn't very useful. Are there any others?

Need to look around a bit more, there are ones running android. I realize its not quite Linux as you are looking for, but its close. Since i'm such a nice guy, here is one -> https://www.amazon.com/Android-Screen-Reader-Upgraded-Version/dp/B00TKF6LNQ [amazon.com]

Shoot, forgot to add: E-Paper is NOT the same as e-ink. Do some more research before you make yourself look stupid.
