NNEPS: Network-Updated E-Paper Signage with Reduced Standby Power Consumption

Electronic Paper Signage (EPS) is used in various ways, such as at bus stops and in menu lists. One type of EPS is a network-updated EPS that updates content via the Internet. In the network update type EPS, a management computer consumes power constantly while awaiting contents. Therefore, a feature of the electronic paper (e-paper), namely, that it does not require standby power, cannot be utilized. To solve this problem, we proposed a network-updated EPS system that reduces power consumption during standby communication. We developed a prototype of the proposed EPS system and evaluated its power consumption.
