Live Paper is not E-Ink, so it shouldn’t have the same inherent issues with ghosting or refreshing.
E-ink is a very specific display technology with ink particles floating in oil controlled by magnetic fields. They don't explicitly state what this Live Paper exactly is, but they do state it's something that solves the downsides of typical reflective LCDs, so, probably one of those but better.
Actual e-inks have the benefit of looking like ink blobs on paper and not square pixels, and the image staying even when power is completely removed, and the massive downside that because they are being physically moved, it actually takes a bit of time so they have terrible refresh rates.
Yeah it looks like a transflective LCD with an (optional) almost orange internal light. Would it make a decent e-reader or note taking device, sure, but it's not e ink.
It's resurfacing old tech? My Sony Ericsson P800 from 20 years ago had a screen that worked great in direct sunlight. It worked best in direct sunlight, the brightest the sun, the better you could see. Downside is that in the dark it had poor illumination
It's LCD with a reflective background and lateral illumination rather than backlight
Transreflective lcd doesn't look great though, especially when viewed at angles, or when the room is bright enough to light the reflective layer but dark enough to require the backlight.
No idea what the niche would be for this as there are already excellent looking e-ink displays which can play video in a pinch. Who's going to go for a shittier looking one just for a higher refresh rate? I don't think many gamers are looking for shitty looking black and white screens.
Fair enough but is that enough to buy a whole different computer with a much worse display? Modern e-ink displays can do probably 10-15 fps on high frame rate which, while not perfect, is probably adequate.
