e-Paper has certainly been gaining ground as e-reader popularity rises, but it is also getting exposure for usage in signs. It might even end up saving lives. Japan is testing out e-paper as a way to provide disaster prevention information to citizens. Toppan Printing Co Ltd, Ministry of Internal Affairs and Communications Kanto Bureau of Telecommunications all teamed up to conduct a test to see how e-paper would work for displaying emergency information around the Toshima Ward Office.
This experiment of displaying local disaster information on electronic papers was conducted by establishing a wireless communication network centered on an emergency center built inside Toshima Life and Industry Plaza. The aim of the test was to prove the effectiveness of the system as evacuation guidance for people who might not be able to return home in the event of a disaster.
The e-paper will be displayed until January 29th. The displays use about 9 watts. e-Paper could be an interesting way to display vital information like this because it can update quickly, whereas printed signage would need to be replaced if information changes. Besides that, as e-paper technology improves, the signage could become more and more dynamic and interesting to read so that passers-by will be more likely to read and remember emergency information.
If the e-paper signs were powered by solar, it just might turn out to be a long lasting, greener way to display important and ever-updated public information.
This test is part of a larger experiment to see how e-paper functions for digital signage rather than printed billboards or even LED signs - an advancement that could minimize energy consumption by electronic billboards significantly.
