A Chinese company called Guangzhou Aoyi Electronics Technology has unveiled a 31.2 inch color E Ink display with support for 18 Hz screen refresh rates.

The Micro Journal Rev.7 is a distraction-free writing device with a 4.76 inch E Ink display, a mechanical keyboard, and a design meant for typing and not much else.

I need some more understanding on some part but that's for another day.

There’s a world in which I could achieve the effect I want if I used a a full-on Pi Zero instead of a Pi Pico, but I am still hoping to keep power to a minimum in order to run off a battery for ~a month.

I might abandon my plans tool use this display for an Oblique Strategies box and look for something better suited to the task.
