I've wished for years that there would be an actual e-ink only laptop. Or (even better) an aftermarket e-ink screen for my current laptop, because I'm quite happy with the rest of the machine.

Are there any e-ink displays with a reasonable enough refresh rate that aren't exorbitantly expensive? I know atleast as of a few years ago that was one of the issues that would've impeded an e-ink only laptop

From what I read some time ago, e-ink displays use almost as much energy as normal displays if the contents change all the time. The one benefit of e-ink is the ability to show static content without using energy.

That is probably another reason that e-ink laptops haven't really become a thing then - practically any use besides maybe basic web browsing and emails would require a decent refresh rate to be reasonable, removing the benefit of using e-ink over the normal display

I have a Hisense A5 cc pro, a color eink android smartphone. The refresh rate is good enough to watch a video

How is the battery usage during the high refresh rate?

I feel like e-ink displays/EPDs are widely used, but underexplored, by major manufacturers at least. The person behind the Modos project already linked by someone else has put a lot of effort into pushing EPDs to their limits and put together the best technical documentation for EPDs that I know of: https://github.com/Modos-Labs/Glider

EDIT: Here's an older demo of theirs: https://www.youtube.com/watch?v=XduK7wn9SE4
