While the rest of the world is waiting for the breakthrough of e-paper as part of everyday life, Japan seems to be a step further. Tokyo-based Toppan Printing has developed electronic papers


that can be used as flexible information displays in the case of major disasters such as earth quakes. Toppan began a limited field test in Tokyo last week. Displays in two different


locations (a post office and a bus stop) showed various information on how to behave when a major disaster occurs. Toppan used displays sized 1 x 3.2m with 240 x 768 pixels (pictured above)


and 60 x 40cm with 144 x 96 pixels for the test. Power consumption stood at 24W and 9W, respectively. Via Tech-On
