Where is the information on how you built it?
There's some info on my Hackaday project listing: https://hackaday.io/project/190478-hyepaper Also the album link in the other comment.
You should upload a massively complicated where's waldo like scene and have waldo appear in different places each hour.
Have a portrait with lots of subtle details but they change slowly over time. Ex. girl goes from earing-less to small earings to big earings. Just have lots of small details subtly change but at a rate which makes them hard to detect.

They look cool. Would be great to have an oled version without a backlight.
LED on oled stands for light emitting diodes, so they are a backlight.
Well done. There would be so many more cool applications of e-ink if it wasn't $2,500 for a 42" display: https://shopkits.eink.com/en/product/detail/42''MonochromeeP... (minimum order 3) For comparison a 42" full-color 60fps TV with remote, speakers, wifi, etc. etc. is $140. It seems like the patent holder could be making a lot more money if they dropped the price.

> sunlight performance of non-eink displays has improved dramatically for example. Can you talk more about this? My phones and laptops are still as bad as ever in direct sun. Did I miss some major development...?
You should upgrade your phones and laptops then: Apple just released a phone that does 2000 nits outdoors, and similarly the MBP can dip into its 1000 nit sustained HDR brightness rating for SDR content if in direct sunlight In reality this is one of those slow burn deals where the improvements in anti-glare coatings, bonding between digitizer and displays, and brightness come slowly enough that it's easy to take for…
I actually have a M2 MacBook Pro and a Pixel 7, both of which get decently bright, but neither of which is really usable under direct glare. And in XDR mode, the SDR colors get super washed out. HDR is a gimmick as far as I can tell.
I'd trade either for a usable transflective display or a regular matte screen from early 2000s Dell. I don't think the answer to glare is to just make the display brighter. That's liking shining a flashlight into your eyes so the sun doesn't seem as bright...
I tried a 3m anti glare coating, and that worked well for keeping out direct light, but it darkened the screen so much it was barely visible at max brightness.
The Steam Deck had some etched glass thing that seemed a little better (maybe the iMac too?) but I still wasn't able to use it in direct sun.
The only display I've used so far that was actually comfortable outside in the sun are e-ink ones, with matte screens also somewhat usable in shade on a sunny day. My M2 MacBook? Useless outside and barely usable under office florescent light. I hate the Apple glare. Makes movies look nice in the dark but useless for day to day office work, IMO.

>For comparison a 42" full-color 60fps TV with remote, speakers, wifi, etc. etc. is $140. Because it's a lot easier and cheaper to manufacture large LCD panels at scale than E-ink film. >It seems like the patent holder could be making a lot more money if they dropped the price.

I didn't vote either way, but this is news to me. As long as e-ink has been around, all I've ever heard were the patent issues. If you're saying it's actually manufacturing difficulties, can you provide any links or additional info? I believe you, but as someone not familiar with the field, I'd love to learn more both to counteract the patent narrative and just for my own curiosity. What is hard about e-ink at scale…

I've never quite understood this sort of thinking. Companies aren't perfect omniscient systems - the people in charge of various companies make poor decisions all the time, based on the same human biases we all have. So yes, it's entirely possible they could make more money that way, but executives simply hear "Lower the price" and run away. I'm not saying that's certainly what's happening, but this implication that a company could possibly only do the thing that's most beneficial to it is... strange, and very common thinking.
That's a very neat project. The only issue I have with it is that it's basically a passive energy waster. It produces images by burning GPU power, when it could instead curate art from an existing amount of art (of which there is more to ever go through, almost in any category). Some projects that use AI could be replaced with other tech and be much more efficient.
My home computer batch processing prompts thru Stable Diffusion can generate and then nicely upscale images at at rate of about 1 every 5 seconds. Or 360 per half-hour. Which means a newly image on the display every day to look at for a year in just an half hour of computation. At about 300W of GPU + 120W of PC, that is 420W * 0.5hrs = 0.210kWhr. This is a rounding error on my monthly electric bill. About six cents.…
