Your original claim was that e-ink displays are incapable of "multiple frames per minute". Even allowing for hyperbole, that's simply not true, and it's well past time we retired that very tired meme. Fact is that e-ink delivers acceptable multi-Hz update capabilities. I've used one such device (Onyx BOOX Max Lumi, with E INK Mobius and Carta HD display). I use it for interactive applications, animations, and video regularly. Yes, it's advisable to change the display mode, but at anything but the highest display quality, most animations are tolerable. Not ideal, but tolerable. And you don't have to take my word for it, there are numerous reviews and videos showing performance. And if you're specifically designing applications or use-cases for the devices capabilities, you can do far better than that. Which would include frequent updates. Appropriate use of technology means playing to strengths, and e-ink has numerous capabilities emissive displays simply cannot match which I've discussed previously, e.g., <https://news.ycombinator.com/item?id=31396797 https://news.ycombinator.com/item?id=31396797>. For a large-format display application you absolutely can have frequent updates. More than once a minute is trivial, and as often as several times a second involves very few distractions or compromises. No, you're not going to prefer e-ink for gaming or as your principle display for streaming video over an OLED or similar monitor. But both of those uses are reasonably within achievable capabilities of products shipped years ago. "Gaming on e-ink" turns up numerous demos. No, it's not what you'd get on a gaming rig, but despite everything you've said and doubled-down on, it is possible: <https://yewtu.be/watch?v=gPwiNVcppmg https://yewtu.be/watch?v=gPwiNVcppmg> (Actual usage starts around 8 minutes in.) Similarly, that gaming rig doesn't do so hot in direct sunlight, persisting display, or low-power consumption. Each tech has its strengths and weaknesses. The distinction between "E Ink" and "E Paper" is made because they're both extant shipping technologies, similar in some regards but based on distinct and different processes, and with different display capabilities. Accuracy, truth, and distinctions all matter.
