Please search my comment history for what I posted about electrophoresis and physics. I don't think they'll be able to get past the physical limitation. To summarize, you either move ink fast but end up losing bistability, or move ink slow, as it is currently. Most people don't realize electrophoresis has remained at about 700ms for an update over the last decade. Tricks like A2 sure with the Dasung, but nothing substantial.
As for the comment about "money/interest", see my comments about why a venture capitalist would have little interest in spending billions trying to create new display tech and fighting hard expensive physics problems when they could get higher rate of return by investing in another software service or ML/AI company. That said, Jeff Bezos spent hundred million or more on trying to get Liquavista working, Qualcomm spent lord knows how much on Mirasol. Great demos, but just couldn't get the process scaled or reliable enough to commercialize. Physics is hard. Physics is expensive.
