Abstract:
Interconnected digital signage is an important driver of enhancing the experience of living in a Smart City, as
it creates a transparent and accessible platform to help a city translate information and communication technologies into
better public services for citizens. But just as e-signage presents an opportunity for a cityâ€™s development, it is not without its
challenges: to enable a truly smart, and therefore sustainable and green urban living space, digital signs should 1. support
energy saving features; 2. be implementable even at the most demanding of locations, power grid or no; and 3. feature superb
visibility in all light conditions. Ticking all of these boxes are smart signs developed on electronic paper technology.
Following is an overview of potential e-paper implementations in a Smart City as illustrated by examples of signage that
Visionect, a high tech company developing the technology for smart and sustainable e-paper signs, has helped implement in
the mobility sector across the globe.
