Any mention of the refresh rate? I didn’t see that in this article and thats usually the downside. Completely fine for books, comics etc but maybe not the best for a computer monitor
Sadly, the technology stagnated for quite some time. This along with the physical nature of how the displays function (moving the pigment particles closer and further from the viewing plane) makes high refresh rates unlikely.
You can kinda cheat and get the refresh rate down to 300ms with partial refresh but that’s still one hundred times slower than a 30hz conventional display.
