That was one of my first thoughts too. It would be awesome if this could simply be yet another display module for the Framework Laptop. It seems as though Framework uses EDP (Embedded Display Port) so an e-Ink display of the correct dimensions which uses EDP would work in theory. Although I'd imagine there would be some work to be done to make it function well.

The physical connector is unfortunately not an indicator that the hardware and software needed to drive an e-Ink display will be similar to an LCD. Sadly, e-Ink displays require custom drivers to function at all, and in particular partial refresh (needed to get sub-second updates) requires targeting known dirty regions of the display and updating just those…hence the extra ghosting in the higher-speed mode of most ebook readers & etc. that use EPDs.

I understand that. My point was that the Framework Laptop uses a standard connector so it's at least possible in theory. (Perhaps EDP is very common, I'm not familiar with the space at all.) In any case, partial refresh is obviously not something that one could expect to work without additional effort.
