Having a "digital paper" is not a new concept, but HP seems to have the edge on the research & development off this type of paper-thin screen that displays the image even when it is not powered! In the future, this could lead to the production of advertising or information boards that would update themselves. What I really want is to make wallpaper out of it. :)
Many subtleties of the display technology remain to be examined, Robson said. "By changing the geometry and spacing of the pillars we can make pixels that can be set to differing greyscale values by varying the switching pulse." As the pixels take a long time to change - updating the complete display can take several seconds - the technology is not suitable for video, but because the pixels can be printed at hundreds per square inch the display can approach paper quality. "For very large displays", he said, "you can just update the area of the display you need to change" ".
