E-paper is making it's way into museums

And the thing that was interesting for me the most, the screens they use:

Now why the screens were most interesting for me? Because "e-paper" name has in the past been used not just for e-ink-like displays, but also for super-low-power LCDs, which is kind of a different thing. Fortunately, Visionect seems to be using "the real deal", i.e. ink-based displays.
Now the only question for me - where can I get my 24” e-ink display for my computer?
Back in the old days I had a Hercules monitor with slow phosphor. I've tried to find some figures on the response rate, but I wouldn't be surprised if it was a similar speed to the eink screen. It was really comfortable on the eyes and I slightly miss it (of course, it was the size of a postcard compared to a modern monitor). So I think an eink monitor could be quite usable for certain purposes.
The thing I'd be concerned about is scrolling. We've got very used to monitors which will scroll smoothly. I've seen monitors which just turned into hash when scrolling; there's a reason why vi and emacs have modes for page-at-a-time scrolling.

Greyscale: $3600. Colour: $4700. There's a 13" model at a mere $999, but who wants that?
Slightly more realistically, there's the Dasung Paperlike:
When smooth scrolling, you lose a lot of time following the animation and waiting for motion to stop.
For some use cases, this would be ideal. For others, not so much.
Can you speedily grayscale into black-and-white? That is, type a letter, putting black/gray into a previously white space (or vice versa, if using a dark color scheme), clearing a single-pixel-wide cursor and installing a new one to the right of the added letter. I don't need the letter to be fully black instantly, I just need to see that I have typed something.
Sure it won't be as fluid as 1080p @ 120Hz, but I'd like it anyway.

Even better maybe, the Onyx Boox Max at 13.3 inches:

I periodically poke around on Alibaba looking for basic, blank e-ink readers but haven't seen much.

I looked at the Boox Max and it looks awesome, but it's a little rich for my blood right now. The regular Kindle costs $80, 10" Fire tablets are selling for $180, so nearly $800 seems like a lot.
Unfortunately it is a bit limited (only supports PDF's out of the box) in what it can do and much too expensive.
And then when you do get audio tours or descriptions, they're often banal and just describe the object that you can already see ("The girl on the left looks onto the scene with a pained expression" so what?!).
What use case is there to change the label "on the fly"?
With a networked display, you click on an icon and type your new text. Done.
And of course, if the label becomes a hypertext, the possibilities are endless; but that will not scale well in busy museums where you can't have anyone hogging the screen for minutes.
For me, the most interesting thing to learn was that "battery-powered" means that the manufacturer expects a battery to last 2-3 years, as the displays maintain no active WiFi connection, and are only woken up sporadically via RF.
How much do they cost? Could not see any pricing information in the website.
From the eink site under the bistable display, the device draws once then really isn't drawing power. [1] They claim that theoretically as long as nothing needs to change, it will stay that way.
So, I guess it really depends on how often museums have to change labels or wish to update the labels. Even if it's a one and done, I do think that the net energy savings of a horde of labels as opposed to new label printings every time would result in net savings both financially and ecologically. Often the labels are not just simple paper and require more resources to make, etc.
I don't think this is necessarily saving any rainforests, per say, but I also don't think it's draining electricity.
Handle what device? As the photos at the link plainly show, these are wall mounted e-paper signs.
Its not outdated if nothing can compete against it in these use cases. The same way I'm typing this message on a 101-key style keyboard with a design that is pretty much unchanged for 30+ years.
I didn't say that =)
Certainly does not like so from the pictures.
(No first hand experience yet, weekend project for this weekend :))
I can't imagine most museum curators would dare to put these on their walls.
And anyway — why constrain all information to a single display. If the goal is to get more information about a painting to a view, there are more solutions both more efficient and kinder to the patrons.
This feels like a case where a simple (dare I say it?!) QR code would have much longer, smarter legs.
