There are some large E-ink display at bus stops in China http://einkcn.com/post/216.html https://www.sohu.com/a/330365162_100238338 I think it's a waste of tax-payers money. Besides why it's not been stolen yet? For consumer electronics I found modern e-ink tablets have very good refresh rate. Watching video is pretty smooth.

> Besides why it's not been stolen yet?

Because it's not really useful to anyone.

Anything worth stealing in China does get stolen, like their attempted solar cell bicycle paths.

A Canvas Made of Pixels (claybavor.com) The most interesting problem to tackle was “the blue glowing screen problem”. One of the many ways that screens give themselves away as screens is by emitting light that is “out of character” with the surrounding environment. They can be too bright or too dark relative to the things around them, and indoors, displays often seem too blue. I solved these problems with what I call…

This is what Apple is doing with True Tone.

But e-ink technology isn’t ready to go out of the gate - the refresh rate is still a significant issue that makes it virtually purposeless for much beyond reading. If it is at this point, it just didn’t happen quickly enough.

I'd like a very large e-ink display for artwork, signage, and metrics. It doesn't have to refresh more than once every several seconds.

Some of the eink displays linked here have 12s refresh, and it does a super annoying flash black/white process while refreshing.

I have never been able to get EPUBs to reliably work on remarkable. My solution is to convert them to PDFs.

You can also install KOReader on remarkable as a reader. Works better IMHO. https://github.com/koreader/koreader

If you do it, do you lose the ability to annotate?

Then you are a niche case. In order to forward a new technology, the masses need to adapt it. Apple, for instance, had to upscale the manufacture of Retina displays by starting with a proven successful product - then moving it to the iPad, then moving it to MacBooks.

We had e-book readers for e-ink, but they stayed at a super slow refresh rate. There was no reason to create a tablet sized e-ink display until the ReMarkable removed the issue of the delay.

Now we will have clones of that, and after that we will see a push to larger displays.

Mass manufacturing is hugely about cost balance vs. demand.

I think digital whiteboards in offices would be a great market for this. Again, though, if you’re going to draw on it at all there needs to be zero latency.

Clay Bavor published in Dec 2015 but Apple filed their patent on March 30, 2015 - seems Apple just got in under the wire there.

Soooo surely someone here knows something about this... at the fancy Harry Potter ride at Universal Studios Hollywood, they have “living paintings” as part of the ambiance, which are very clearly digital. They are large and in color, TV-sized. But they look like they are not emitting their own light. My best guess is carefully controlled brightness and some special coating (they have a paint-like finish), but that’s just a guess. Anyone know more details?

The technology is there, but E Ink (the company) is steadfastly refusing to lower prices because they believe there's a market for this. Now go to Alibaba and find that you can get a flexible, full-color OLED sheet for the same price as a given size E Ink panel. Go on eBay and buy an older NOOK device (they all ran Android) for $20, tape it to your wall, and point at your web page of choice.

A great example of patents strangling innovation. If anyone has more concrete details on the way this company is holding back this technology I’d love to read details. Thanks!

I've long wondered why electrophoretic displays (the generic term for E Ink, which is a proprietary name) continue to be exponentially more expensive at sizes larger than a Kindle while other technologies like OLED have become vastly more affordable in larger formats over a similar timeframe. The best I can tell is that there just hasn't been an investment in scaling up fabrication anywhere near what the likes of LG…

How about ClearInk? https://youtu.be/kE_byDwLjxk?t=34

Also, ye olde e-Ink has plans for Q3 2020: https://youtu.be/vOTid3I-4EI
