Bridgestone shows color e-paper with pen input

Bridgestone color e-paper

At a trade show in Tokyo this week, Bridgestone showed off a color electronic paper display that has support for pen input. Comprised of Bridgestone's QR-LPD electronic powder and granular material along with a color filter and Wacom's electromagnetic induction-type pen input tablet, the display has a faster refresh speed to accommodate the pen input. It now takes 0.8 seconds to refresh the screen, a marked improvement over Bridgestone's previous A4-sized e-paper display that required between 10 to 15 seconds.

While Bridgestone did not elaborate, it did say the passive matrix panel's speed improvement was made by improving drive technologies. The added speed let the display follow the pen input and smoothly display written graphics and text. Bridgestone has not revealed plans for a commercial release of the color e-paper display or what it would cost. [via Tech-On]
