While we're still waiting for our
electronic broadsheet (hell, we'll settle for a tabloid) it looks like folks in Toshima will be seeing quite a bit of the e-paper as they hit the streets of this Tokyo ward. In a test conducted by the Ministry of Internal Affairs and Communications, the signage has been installed in the proximity of the Toshima Life and Industry Plaza, where a wireless network was established to provide updates in case of an emergency. There are currently two signs: one in the lobby of the post office measures over three meters across and sports 240 x 768 resolution (the paper has 4mm pixels), and holds down power consumption at about 24W. Stationed at the Higashi-Ikebukuro bus stop, the second sign is 60 x 40 centimeters with 144 x 96 resolution, and power consumption here is about 9W. The test will run until January 29th, after which point the city will have to rely upon its usual civil defense repertoire -- which is believed to include the vigilant eye of Honda's 49-foot
ASIMO.

That looks so awesome! for hax.
Isn't 9W's alot of power for E-Paper? Or is that for the wireless communication network, of which the display is just a tiny part of?
Probably for the lamp/backlight. they problaby want to make it so that it can be seen at night or bad weather, otherwise it probably won't serve its purpose very well.
epaper doesn't do backlights, but maybe an edge light though.
But perhaps the mentioned powerdraw is during changes on the display?
i scanned the icon it sent me to http://tobus.jp
I thought e-paper was not supposed to use power unless it is refreshing? Or is the power consumption for the polling? If so could they not use a ultra low power chip, after all it does not need to be powerful in order to get data.
You are correct on all points.
Does the signs have some sort of battery backup unit? You know - in case of emergency...
e-paper doesn't lose its content when power is disconnected, which is one of the great benefits. The other plus of this technology is that the visibility is based on contrast: the medium doesn't illuminate, so cutting power doesn't change the readability.
The first use will most likely be - Yurakucho line delayed due to "accident"
Does that really happen a lot? Really, they should have platform-side doors too or something.
Oh, and it's a bus stop, not a subway stop.
Everything on this sign is about transportation...
a bus stop sign requires 9W, no wonder we are in global warmining and it's irreversible.
also this makes me think of a gigantic original gameboy screen
Global warming is irreversible only because we haven't figured out a way to build space pipes that sucks all those C2O2 out of our atmosphere or to build some space power stations that uses the temperature differences between our atmosphere and the outer space to generate electricity, cooling us down while powering our gadgets wirelessly.
Oooops, "C2O2"!!!!, lol!!!.....should be "CO2". Frigging Fn key together with this worthless spellchecker surely works wonders.
Looks cool, I guess these e-paper technologies are far away from a U.S. rollout?
In case of Gozilla Attack...
In the future, paper as we know it won't exist anymore, and we'll all be required one sheet of notebook paper for school.
does that say "All your base are belong to us"?
Hmmm... When I scanned it, it lead me to a site that translated to...
"In case of Gojira or Mothra attack, do not use elevators."
