Those fortunate enough to traverse the halls of Embedded Technology 2007 could've seen Seiko Epson's latest wonder up close and in person, but for the rest of us, we'll have to settle for the above picture and a drool-worthy description. The prototype e-paper terminal measures in at just 3-millimeters thick and weighs only 57-grams, and it's even equipped with a USB port. Furthermore, it features a 6.7-inch display with a luscious 1,600 x 1,200 resolution, but the unit on display could only handle grayscale imagery. Also of note, the entire unit was powered by a single button cell battery, which enabled the screen to be redrawn upwards of 1,400 times (at 0.7-seconds per redraw) before running out of juice. Details surrounding its eventual commercialization were pretty much par for the course, meaning your guess is as good as ours at this point. Two more snapshots after the jump.
The terminal is driven by a button cell (CR1220). The screen can be redrawn for 1,420 times with one button cell because the electronic paper consumes power only when the display is redrawn. The time required for redrawing is 0.7 seconds. While the Seiko Epson's existing e-paper takes 5 seconds to redraw the screen, the company enhanced the redraw speed by improving the drive circuit, etc.
