Samsung's new 32-inch EM32DX color e-paper display offers an impressive 200-day battery life, Wi-Fi/Bluetooth support, and up to 60,000 colors—making it a highly efficient option for digital signage. For those looking to leverage displays like this in business environments, solutions such as kitcast.tv/enterprise-digital-signage provide centralized control and seamless integration.

If the battery were solar charged it would be a lot more eco-friendly. Normal signs don't need any power and these will cost a hell of a lot more and take more resources to manufacture. It'll have a place but not as a total replacement for regular printed signs.
