Bridgestone’s already showed off some fairly impressive e-paper displays, and gone into mass production with displays for inventory tags and whatnot, but it now looks like the company is now set to make its biggest push into the market yet. According to Tech-On, Bridgestone will be announcing details of its plans in July or August, but it appears that the announcement will concern e-paper displays for e-book readers, at least one of which will be A4 in size. That particular screen was making the rounds of exhibitions back in April, and makes use of the company’s proprietary “electron powder and granular material” which, among other things, lets the screen rewrite in just 0.8 seconds. Of course, there’s no word on any actual devices using the e-paper just yet, but we’re hoping that’ll be among the details announced in the next month or so.
