Havent looked into this much- What is the maximum 'refresh' rate you can get out of something like this?

The page says 15s.

  That is what the page says, but can that possibly be right? I know e-ink tends to have very low refresh rates but taking a full 15 seconds to redraw seems excessive. I have found sites like this often have pretty obvious errors on them, is it likely this is correct or a typo?

    15 seconds doesn’t make sense for a handheld reader. Are there other scenarios where it does make sense?

      Information displays in retail.

      Event specific signage such as 'Donner Party' in Conference Room C could be useful for many hotels and convention centers.

    I think colored ones typically change the colors in sequence, so it seems like that could be correct.

    That's actually not too bad for a multi-color e-ink display. The last color e-ink display I looked at had an even longer refresh interval.

    Some months ago I saw a larger one that took half a minute of cycling through different states to fully display the final image. So 15s seems reasonable.

    My understanding is that the refresh time tends to increase significantly with the number of colors displayed.

    E-ink is commonly used in signage where it won't need to change again for a week or more. 15 seconds is fine when your required average refresh time is measure in days. I am really looking forward to the day when high refresh rate e-ink displays are common. The B&N Nook from about 8 years ago could be modified to successfully play flappy bird at about 10hz, but it was pretty ugly to use, requiring a black/white full clear of the screen to zero out the image every 30 frames or so.

For single or double-color displays, you can do pretty decently. This Applied Sciences video on YT goes over what's possible. https://www.youtube.com/watch?v=MsbiO8EAsGw https://www.youtube.com/watch?v=MsbiO8EAsGw
