DNP to Launch Energy-Saving Digital Signage Incorporating Renewable Energy

Anti-crime applications also available

Dai Nippon Printing Co., Ltd. (DNP) is pleased to announce the April 1 launch of an energy-saving digital signage that incorporates renewable energy. The new signage is available in two versions; a hybrid system, driven by a combination of solar and wind power, and a type that operates on solar power alone. With this new development it is possible to transmit emergency information during disasters, and as anticrime applications are also possible by incorporating the use of surveillance cameras, the resultant digital signage will contribute to the development of safer communities.


Recently we have witnessed increased social interest in the efficient use of renewable energy to counter global warming, and many companies and local authorities are now engaged in the development of renewable energy. At the same time, the Great East Japan Earthquake of March 11, 2011 revealed that transport systems can be paralyzed, resulting in vast numbers of commuters being stranded and unable to return to their homes. Power outages and heavy communication traffic also saw information terminals, including smartphone systems, fail, and presented the challenge of large numbers of people being unable to obtain disaster information in a timely manner. In November 2014, DNP developed an energy-saving digital signage system that incorporates renewable energy in order to overcome these various challenges. Now, following field tests, including those related to capacity checking, along with equipment durability and performance confirmation, the Company is now pleased to be able to launch sales of the new system.

[Anticipated Usage Examples]

1, As an information transmission system in both normal times and during emergencies

The new system can be used as digital signage, broadcasting company ads, locally-driven information and disaster prevention tips in normal periods. During disasters the system can also be used as an information transmission station broadcasting useful information for those affected in a timely manner. This information includes, earthquake early warnings, notification of evacuation sites, disaster information, personal safety confirmation, infrastructure and transport operation information, along with the latest news and weather forecasts.

2, As a symbol of corporate CSR improvements and eco-activities

The new system sends a strong anti-global warming statement, and is an effective CSR and/or environmental preservation initiative when companies and local authorities broadcast information.

Optional services include;

3, Promoting the development of safer communities through the use of surveillance cameras

With this newly developed system it is possible to add surveillance cameras, contributing to efficient power use throughout the town or city, and the development of safer communities.

4, Wi-Fi access points

The number of overseas tourists visiting Japan is rising year-by-year. Feedback indicates that many wish to see the establishment of more Wi-Fi access points. This is possible with the new digital signage, which as a result can be offered as a measure to promote inbound tourism.

[Equipment Features]

1, Energy-saving system combining renewable energy, LCD, and E-paper

During normal times, energy sources combine the use of commercial energy and renewable energy derived power. In power outages, information is broadcast using renewable energy and power from storage cells. In the case of the hybrid system, LCD can operate for approximately four hours following power outages. E-paper can be driven by storage cells and renewable energy, and hold information for approximately three days even if renewable energy levels hit zero.

2, Personal safety confirmation

The hybrid type digital signage includes a DNP developed information distribution terminal to target mobile devices, including smartphones. This is an optional add on in the case of the standard type system. Users are automatically guided to the URL merely by passing their smartphones or mobile phones over the information distribution terminal. By setting up a personal safety confirmation site, it also becomes possible to confirm the status of friends or loved ones in times of disaster.
