Wow, this is great! I've been hoping for eInk with good refresh for years, and seeing it in action in your demo is very cool.

> The screen can refresh up to 30 times per second, this will degrade the eInk display rapidly. Do not use with fast changing content like videos.

Have you noticed the degraded display in your Kobo? I imagine it's not uniform across all pixels, since editing would mostly be localized to your cursor area (though scrolling and other actions would be wider). I'd also be interested in hearing what the timeline looked like for the quality drop, since it sounds like it's a function of the total number refreshes for each pixel.

Thank you :)

I haven't noticed any degradation, but I put the warning up just in case. There is research suggesting that the ink "drops" stick together or break up after so many refreshes.

I thought 11 years ago that e-ink with good refresh was achieved, seeing bookeen's prototype display videos and full screen scrolling.

But all e-ink devices I have seen since were slow and would form time to time show remanence.
