One of my friends works on an e-ink product. My understanding is that one of the major trade secrets are the e-ink waveforms (the sequence of voltages used to print and erase content on the display). They are shared under NDA and baked into product firmware. Apparently the open-source versions are significantly worse.

Or perhaps that's just what they want you to think...

That can be overcome, especially with sustained collaborative effort.

But the production of the displays, controller software aside, will not be "cheap".

Hearsay, but I've read in the past that these were tailored specifically to the display, so difficult to actually collaborate since each display is a little different.
