The Bridgestone e-paper is suited for e-readers,it is A4 in size, and has a fast refresh rate - 0.8 seconds to refresh. This makes it possible to do pen-input touch ePaper devices.

The faster screen refresh speed was realized by changing the driving method, not by improving the e-paper material. Specifically, the pattern of applying voltage was optimized to "reduce waste," Bridgestone said.

The company will also offer a colored version of the e-paper by combining the black-and-white e-paper with an RGBW-type color filter based on a glass substrate.
