I work in the display industry. My take is neither will happen. Lets start with B. > B) Color e-ink displays get good enough for interactive use, movie watching, etc. There is no commercially sold genuine color e-ink today. Kaleido is a grayscale e-ink with a color filter laminated on top. Kaleido Plus is just the same with a light guide. E Ink did show off a genuine color display back in 2018 called Advanced Color and marketed as "Gallery". But it would take 30s to display an image and it was 32 colors or 16 colors. Not 16-bit color. I mean only 16 colors. E Ink tried to get the industry to buy in and start making products using this technology but nobody really signed on. They revamped their production to then start producing 7 color panels in much smaller sizes like 5" for signage. I heard that hasn't hit the numbers they needed to even cover their RnD costs. I doubt it will be a commercial success. When you say "good enough for movie watching", I'll say that'll never ever happen with electrophoresis. You can't violate physics. Either a pigment particle moves slowly and stably or it moves fast and is unstable. You'll never be able to get both. That's why newer technologies by various startups like ClearInk sacrifice the bi-stability in order to get fast video speeds. But look at the market response, the market isn't exactly embracing that either. Venture capitalists aren't exactly eager to fund the billions needed to create new display tech when they could invest in some new internet services startup or AI/ML startup instead. As for A), these are all emissive technologies. They will by their physics always be distinguishable from paper. As to whether you'll care or not, that is something I can't predict.
