DNP Develops Natural Energy-Based Energy-Saving Digital Signage

Dai Nippon Printing Co., Ltd. (DNP) has developed an energy-saving type digital signage integrating a natural energy system, composed of solar and wind energy, with a rechargeable battery cell. This newly developed signage is mounted with a monitoring camera, facilitating use in line with crime prevention purposes, and can also be used to distribute emergency information during disasters and in safety confirmation.

For a period of approximately one year from November 6, 2014, it is planned that the signage will be installed at the DNP Gotanda building in Tokyo, and field tests conducted with the objective of marketing the system based on the results.

[Development Background]

At present, there is increased public interest in the effective use of natural energy as an anti-global warming measure, and many companies and local authorities are making efforts to increase the use of clean energy. At the same time, in disasters, such as earthquakes, it is expected that public transport would come to a standstill, with the resultant effect that many commuters would be left stranded, and unable to return to their homes. Also, in instances of power outages, information terminals, such as mobile phones, could no longer be relied upon, with the possibility that many people will be unable to obtain the necessary disaster information.

DNP has developed this energy-saving type digital signage integrating a natural energy system as a means to resolve this very issue.

[Equipment Features]

  • The information display device is mounted with a 21.5 inch Liquid-Crystal Display (LCD), 10.7 inch e-paper capable of displaying variable information, and 17 X 50cm segment display e-paper. The e-paper consumes energy only when rewriting information, and not while displaying that information, and is an information display device with superior energy-saving qualities. In emergencies and disasters, it is possible to renew the e-paper using natural energy, and transmit the disaster information and evacuation information that people need.
  • The newly developed system is also equipped with rechargeable battery cells as a backup during power outages. The LCD is capable of displaying information for approximately 14 hours during power outages, while with the e-paper it is possible to renew information using natural energy only.
  • The signage integrates an information distribution terminal developed by DNP aimed at smart phones and mobile phones. By waving the phone over the terminal during disasters, it is possible to access a safety confirmation site.
  • It is also possible to include a monitoring camera in the system, and use it in crime prevention uses for preventing crime in local areas.

[Overview of Field Tests]

Field tests will include tests of power volume, equipment durability, and information transmission contents that anticipate emergency situations. Apart from news, pinpoint weather forecasts in an area 1km in diameter from the DNP Gotanda Building in Tokyo, and DNP releases, and with the cooperation of the local police and firefighting authorities, these tests will also broadcast information believed to be of use to the surrounding area, including crime and disaster prevention information, along with earthquake information.

[Forward Looking Developments]

Based on the field tests, DNP will investigate necessary functions and specifications, along with prices. Apart from the standard mounting of the crime prevention and monitoring camera, the Company will also consider expanded functionality, such as multi-lingual responses for use by tourists from overseas, and the provision of Wi-Fi spot functions as an information transmission base. And while considering such inbound responses for overseas sightseers, DNP also aims to instal the signage at designated evacuation locations, such as public facilities, parks, and schools, and commercial facilities where many people gather, and frequently used major roads in cities. The Company also aims to forge links between this new signage and existing signage installed at facilities and company offices, and plans to utilize the overall system as an emergency response system for emergencies.
