I still have no comprehension of EInk's branding, so I'm not sure if ACeP is the high color thing or gallery plus is, but gallery plus is ACeP and this is gallery plus.
I'd love a color e-ink art frame, but I hope maybe I can find one in a store to see first.
Rewritable color e-paper with paper-like visibility is born!
Digital signage that can rewrite and distribute contents, and the installability of paper posters that can be placed anywhere, are realized at the same time. The new ePoster, an environmentally friendly product that can be displayed with 0W power consumption, will change the way information is transmitted.
Constant display with zero power consumption*1
Once displayed, the display is maintained even when the power is turned off. Since no power is used except for rewriting the display, overwhelmingly low power consumption can be achieved. 1 Power connection is required for display rewriting, auto mode, and eSibnage S (sold separately) operation.
Paper-like easy-to-read screen
Reflective display with no backlight and a viewing angle of almost 180°. Just like paper, it is easy on the eyes even after long hours of continuous viewing and offers excellent visibility in bright locations.
Thin, lightweight, and free installation
The thin, lightweight design allows for easy and free installation in a variety of locations. No power cable wiring is required, so it can be installed in places where a power source is not available.
Contributes to environmental friendliness
About 30% of the plastic material used for the main cabinet is recycled. Recycled paper is also used for the packaging cushioning material, contributing to environmental friendliness. Replacing paper posters and POP can contribute to cost reduction and CO2 reduction in printing, sorting, distribution, and repositioning work.
>just about every other display tech came down in price by a factor of 10 a few years after it was invented.
No, the successful display techs came down in price. The commercial flops that nobody hears about are the same price as always (i.e. astronomical), because they have no economy of scale.
Maybe it will be someday -- I'm not entirely sure if it's fundamentally constrained by the physics of it, or how much further engineering progress can improve it. Curious if anyone here knows.
When you see these things switch especially at night in your peripheral vision, it can be a bit jarring, especially if you suffer from vision issues.
Hell, make billboards illegal period, as a few New Wngland states do.
I think it's baaaarely in the realm of science fiction right now, but I'm sure someone is working on it.
Me too. I see them used at small scale, like price tags at the local grocery stores (I'm told Aldi's in the US as switched to these), and I fanboy a bit when I see them used in the wild.
CFA tech is what E-ink's "Kaleido" line uses, whereas ACeP is used in the "Gallery" line.
Gallery Plus means, IIRC, they have 7 different dyes in each pixel (and takes 10ish(?) seconds to refresh, with the latest model). There's also the Gallery 3, which is an 8" screen that has ~4 dyes and can actually update the screen in a reasonable timeframe for interactive use.

One cool trick is to learn about a TDL is to visit nic.TLD to get info about the domain, for example https://nic.sharp/
Because I've found some that don't have it, like https://nic.amazon
For that amazon link, I think the underlying website is just flakey. I was able to get the page to load once, here is an archive link of it working https://web.archive.org/web/20230616013716/https://nic.amazo...
Some examples: https://whois.nic.sharp http://whois.nic.amazon https://whois.nic.horse https://whois.nic.google https://whois.nic.trust
See the gTLD guidebook here: https://newgtlds.icann.org/sites/default/files/guidebook-ful...
Section 4.1 on page 268 of the PDF covers whois.nic.$GTLD
Country codes can basically do whatever they want.

Will lack of backlighting cause difficulties tho?
Being able to change the sign quickly/often for new advertisers might also bring in more money. E.g. you can now sell different advertisements on Friday versus other weekdays, and more specialized Christmas advertisement.
Counterpoint - a large e-ink advert market means (likely) cheaper e-ink products for consumers. E-ink isn't likely to replace cheap paper, it's more likely to replace LCDs and OLED screens which are already more obvious/intrusive as they're self-emitting.
In theory, the big screens could be roughly comparable to LCD screen prices, like the 6" e-ink screens already are.
They key cause of cost in e-ink is lack of demand, and more specifically lack of demand compared to LCDs. LCDs are produced at a rate of billions per quarter, they're so stupidly cheap it's almost unfair to compare them with e-ink. Point is, LCDs will always be cheaper unless demand changes.
Don’t know what it is called in English properly to search for such things..
e-ink is a big deal in Taiwan right now. The prices should come down fairly steeply in the next year or two.
In what way? What has changed?
This sounds similar to signs I've seen in some malls. I'm not sure what they're called though.
If it would cost 30 dollars, I'd buy many of them, hang them on walls, take them down every few months or years to change the picture. If it cost 300 maybe I'd buy one of them. At 3k, zero. Of course I'm not the target at that price point.
Everyone wants a giant $30 e-ink screen, but realistically they'll never be as cheap as an LCD of the same size and nobody's willing to pay even that price.

[2] People's/site's answer defaults to the "eink uses no power to maintain an image" even when the question asked is specifically about power use during updates.
So yes, of course NFC can be isolated from the displays power usage, the originator of this thread was just suggesting it would be neat if you could power it via NFC.
But NFC doesn't provide nearly enough power, nor likely enough bandwidth to do that in a reasonable amount of time.
The devices for updatable price labels based on eInk already exists and I mention it in my post, it's powered by a low self discharge battery. Those IIRC use a special radio fob that connects to your phone instead of using NFC but you could probably do a largely drop in replacement for the radio circuit with NFC but that still doesn't solve the issue of updating the eInk screen. That's an order of magnitude more power required.
It's extremely obvious the person you replied to was talking about controlling the tablet, not supplying electricity to it. Their subsequent remarks are beside the point, this is what led to the confusion in this thread.
Or if it's outdoors, add a small solar panel.
edit: A quick skim of the massive Qi specs makes it seem like maybe it can boot strap but I'll be honest I don't have the time to really dig in super deep into it. Bing Chat also seems to think it can but its sourcing is a bit spotty and the link it provided for that isn't actually saying anything about unpowered bootstrapping on the Power Receiver side.
The only issues I can think of there are I'm not sure if the Qi process can start up without power on the receiving end, the source device isn't always broadcasting power afaik so I don't know what the trigger is and if it requires some communication with the receiver device. The last is the NFC has a pitiful data rate of ~424 kbits/s but if we're powering it through Qi we can use more power hungry transfer methods to speed it up.
But it would also require a good supply of games to download. Unfortunately there has never been a successful standard file format to download boardgame graphics, so all virtual tabletops use their own (usually closed) formats.
I'd love to have a few of these in my home and then have them change the photo each night. Much easier than changing out prints of my photos.
Not quite UHD, but more than HD.
Such devices have been on the market for years.
I've owned an Onyx BOOX Max Lumi (13.3" e-ink Android tablet) for nearly 3 years now. Monochrome 16-shade greyscale (with dithering for better presentation of images). It's excellent for reading straight text, line drawings, and most webpages, though a pagination-based navigation is much preferable to scrolling.
Refresh is ~8--16 Hz, though that varies by display mode. It's possible to view video on the device, though you'd generally prefer not to. Animations are generally annoying A.F.
Higher power requirement of course but would be really cool for art.
That's great for a one-off enthusiast project, and make a blog post and video about it.
Or, if it's instead tech industry SOP: Tie it into a subscription cloud service for updating the signs (initially free), with a tablet UI for the independent cafe manager, and enterprise management dashboard for chains of cafes with mass-produced homey feel, and also run display ads for whatever revenue, and spy on all the business's data that goes through it, to sell the surveillance data to whomever will pay.
Back to the original inspiration: maybe the artist enjoys drawing the signs, and can do it in a more appealing, humanized, genuine way, so automating it would be counterproductive, at least for independent cafes.
You know, that almost sounds like eInk ;)
Calling them patent trolls seems especially weird since since the Eink company actually produces a lot of stuff.
I guess it's okay here though, because [passionate story about side project idea using eink that could be tinkered on but never actually idealized into something].
If the real problem is the first one, then implicitly there is a need to propose something that works better. And that is no obvious (but it's obviously not simple).
Every new generation of LCD and OLED has plenty of patents, and there are affordable products eventually. OLED in particular started out very expensive and now is everywhere.
E-Ink is just tough.
Overall you can argue they as a company would have done better to allow the tech to broaden and reap licensing fees, but you can't argue that it isn't their decision to make. Or, you can, but you aren't arguing against these guys but the system of IP laws in general.
I've heard that Eink is notoriously hard to work with and as an outsider looking in, their product development is frustratingly slow, but it's a public company (acquired by a Taiwanese company a long while back), and looking at their financials over recent years, their operating margins seem to be 10-15%, which I guess beats a lot of other display companies, but still doesn't seem so impressive vs other semi/tech companies. That no one's disrupted them over the past few decades I think speaks to how it's more than just an IP moat at play.
From whom? I asked someone who commented this on HN and the person replied saying that they had refused to help him debug his 3 display project. So yes, any display company is notoriously hard to work with if you're not buying a reasonable quantity of their product. It is like saying Samsung Displays is notoriously hard to work with as they're not helping my startup debug our problems where we've bought a grand total of 3 displays this year.
Where? How? Please share some evidence so that your claims can be verified.
That being said, if you don't need a lot of color, the Kaleido 3 eink devices are very good and very fast. I've had a color Boox device for the past year (with their GPU-driven refresh technology) and it's quite zippy on the refreshes. The color is filter-based, so not so vibrant, but it's great for highlighting (looks sort of like newsprint in terms of color and sharpness) and for me, is "enough" color w/o giving up anything.
I could have random cool photos and artwork cycling. It would be well worth it.
