Recently, I have come across some interesting developments in the e-ink space. Although I haven't had the opportunity to test DASUNG monitors myself, but I read positive reviews. It is impressive, these monitors have extremely fast refresh rate. Yes, they are pricy. I am intrigued if something has changed technologically?

Your comment made me curious, but after looking at a teardown blog the 13" Dasung Paperlike uses the same ED133UT2 panel by E Ink as in my DIY newspaper project, which is a panel originally released about 2016/2017.

That said getting good partial refresh performance out of a panel like this requires a good controller and good code (after having written a driver for one such controller recently), and developers and product integrators have gotten more refined at this. Refresh speed and display quality are still a trade-off here though, expressed as different waveforms when driving the same display.
