I loved reading your insights on the tech! E ink is such a fascinating tech... Pity about the NDA though, I would love to hear a lot more!
The title is mentioning e-paper though and if I have understood correctly that could imply a different tech is being used here. So here's what (I think) I know, e-paper is a broader category that includes other tech that is not e-ink but very low power screens, such as the screen used by the old smart watches Pebble, which had a color memory LCD that could achieve something like 20 fps or something like that? Just enough to create nice animations and fluid UI. Of course changing the screen meant higher consumption, but the LCD could keep the image by using a very low but non-zero energy.
Although it seems that e-paper and e-ink are commonly just mixed as if they would be the same, while to me e-ink is a type of e-paper. Do you feel my understanding is correct on how the tech is categorised and maybe the screen from the article could be memory LCD or something else that is not e-ink?
The article itself mentions E Ink's Kaleido 3 technology. I'm not really sure on the semantics of "e-ink" vs "e-paper", but your take sounds good enough to me. I do know that E Ink makes a product internally (maybe also externally? idk) refered to as "ACeP", which stands for "Advanced Color e-Paper", so e-ink definitely classifies as a type of e-paper.
