That's an interesting case of a display being off actually indicating something ("loss of power") which can't be replicated with a bistable screen.

On the other hand, you probably don't want that glow of an active screen all the time. Status LEDs are annoying enough.

This screen is entirely independent, with its own power source, so unlike most bistable screens this one could also report when its connection with the Machine is lost, and in a different way than simply turning off.

[cubefox]

It's own power source... Let me guess, solar cells? Batteries? A separate power plug?

[jdiff]

Just a lithium battery.

Now I wonder how it gets recharged.

[jdiff]

Feather has a charging circuit on board, and its usb port has a channel carved out for it and is close to the edge

My kindles usually show a dead battery graphic when I get back to them after a long time away... With enough power storage and the right trigger, this could be done.

Yeah with a battery you can change the screen to "dead battery" when the battery is almost dead.
