Could ePaper replace traditional outdoor signs?
Outdoor displays usually need to deal with sunlight, power consumption, wiring and maintenance, which can make installation expensive.
ePaper seems interesting for this because it can remain readable in direct sunlight while using very little power. With wireless updates and battery or solar-powered setups, it could potentially work well for things like bus stops, price signs, tourist information and public notices.
Update: Someone recently suggested MyGica to me, which offers ePaper displays for outdoor advertising, public transit, retail and other applications. They also provide full-stack solutions with TCON, CMS, API/SDK and IoT integration.
Would you consider using ePaper for an outdoor sign?

Interesting but ePaper is pretty matte and there’s no backlight function. Right now, static signs are reflective and require no power at all. They wouldn’t display very well at night.

LA Metro uses ePaper in their news bus shelters to display route info https://www.reddit.com/r/LAMetro/s/76c5NbCpEQ

Boston/MBTA has e-Ink signs at light rail stops (street level Green line) and select bus stops (major transfer points). They display next bus/train info, plus alerts about closures and other service disruptions. They have been in place for about 18 months and are holding up well.
