I had never heard of Clearink before but, damn, their tech does look quite impressive[0]! I would LOVE to see a ReMarkable with such a screen!

At @4:08 the company representative says

> Our current schedule is to bring gen-1 productions to the market in 2020

Well, I guess I'll be crossing my fingers that it'll happen as soon as this pandemic over.

All these product shots look fake and I don't see any specifications, just vague claims. I'm curious in what way it seems superior.

They have short response times and higher refresh rates. Their online videos show video capable devices.

The technology page makes me thing the viewing angle is going to be more narrow than e-ink; the shape of the surface and the difference in index of refraction when on and off is going to determine how well they can do on that metric, but the complete lack of any mention of viewing angle makes me think it's not great.

It's B&W and much lower contrast than current gen e-paper, but viewing angle looks great (maybe 120 degrees confirmed from the video?). They definitely need a matte surface though; that glare was terrible.

Is that what one would find in those color e-ink HiSense phones?

No they usually use Kaleido. They don't specify but it matches with the poor color saturation and 4096 colors.

Kaleido is a b/w eink panel with a colour LCD overlaid.

There's tech that looks much better like eInk's ACeP (much stronger color saturation) but it needs multiple flashing refreshes to update so it's not feasible for interactive devices. They're just being marketed for advertising and the like.
