You could put them on pieces of paper, conceivably, or paper-like material or pieces of polyester plastic. Right now the prototype is a low-resolution monochrome display, but Lucent and E Ink are working toward increasing its resolution and color capabilities. For comparison, laptop computer screens are just under 100 dpi. The electronic ink is compatible with high resolutions, having been demonstrated at resolutions as high as 200 dpi. It is the electronics of the portable display that need to be further developed.
Color is a bit more straightforward.
Liquid crystals themselves have no inherent color. To get color on your laptop computer, display manufacturers use a red a green and a blue color filter. So for us to obtain color, most simplistically, we'll just adopt the same approach. Newspaper companies have taken an early interest in E Ink's research and development. Investors in the company include McClatchy Co., Gannett Co. Inc. and Hearst Newspapers, whose chief operating officer and head of its newspaper division, George Irish, sits on E Ink's board of directors.
