While it'll always be difficult to accept innovative technology from a company that makes our tires, there's just no faulting Bridgestone's work in the e-paper space, or their latest color entry, above. The 13-inch display, based on "QR-LPD" tech, has what looks to be great color depth, along with snappy 0.8 second screen refreshes (great for this screen size) and actual Wacom-based pen input. There's video of it in action after the break, and if we didn't know better we'd think they were putting a Sharpie to a perfectly good display. Unfortunately, the image does look a little dim at the moment, so hopefully that's something Bridgestone can improve upon as they approach commercialization -- whenever that might be.
