It's been a few minutes since we've heard any news regarding color e-paper, and now Ricoh has announced that they've taken a tip from their copier business to create a technology that displays hues fifty percent brighter than those currently available, retaining the graphics even when power is turned off. Unlike other technologies, which use layers of red, green, and blue light separated by sheets of glass, this new iteration uses layered electrochromic compounds that turn cyan, magenta, and yellow variously when electricity is applied -- and if that weren't enough, the company's gone and altered the molecular structure of the compounds to retain their color even when electricity is removed. Rather than using glass, the layers are separated by some sort of clear insulation, resulting in a lighter device and a brighter appearance. The company is looking to bring this to market within the next five years. [Warning: read link requires subscription.]
