For the past few years, we've seen a bunch of e-readers and e-notes featuring E Ink's Kaleido 3 technology. But if you thought that this color ePaper was limited to handheld devices, think again. E Ink has now shown off 75-inch outdoor displays.
This is more to replace the digital signs that currently use LCD/LED displays. It’s more readable in the daytime because it doesn’t need a ridiculously bright backlight to compete against the sun. Compared to those signs this uses dramatically less electricity because it only uses electricity when the image changes (reading the article some of the options run off a small battery pack like you could use to recharge your phone a few times). Iirc you also don’t really have burn-in issues with e-ink. It looks like their color reproduction has gotten a lot better with the latest generation, so this could be a really good fit for a lot of outdoor digital signs.
