If the tech becomes attractice enough (high visibility in direct sunlight, lower power consumption, etc), maybe we'll see more public advertisers switch to them for digital signage, significantly increasing the demand and volume.

One can dream..

The transit stop use case really does seem to be ramping up, including the Massachusetts Bay Transit Authority currently adding them to most surface Green Line stops: https://www.mbta.com/projects/solar-powered-e-ink-signs

Transit was one of the two core practical applications the Visionect founder mentioned in Nov 2020: https://news.ycombinator.com/item?id=25067359

Interesting. Now I'm curious about the tech used behind it to transmit the info accross the network. I'm wondering if a LoRa/LoRaWAN-based mesh network could do the trick to avoid using some kind of cell data or wired infrastructure, but also be energy-efficient enough to work using only solar power.

Aren't all e-ink displays highly visible in direct sunlight? You need exterior to even use them in the first place

I meant compared to traditional displays.

E-Ink is a ton more visible in direct sunlight compared to traditional displays?

[m-p-3]

Quite a bit more.

Of faster than light travel? :-) They're limited by the physics of electrophoresis.

I mean there's other ways than refresh rate where there can be improvement, especially on color eInk displays. They managed to increase the DPI on this version after all :)
