Citizen's curved digital clock uses an electronic paper display (EPD), making it far more flexible and readable, and far less power-consuming, than traditional digital clocks. The clock uses E Ink Imaging Film, which requires no backlighting to display an image but is viewable in both low lights and bright sunlight, and from any angle. Once an image is displayed, there is no power involved in keeping the image on the screen, so it's highly efficient.
A thin, curving clock may not be an earth-shattering innovation, but e-paper and e-ink have exciting potential to put vivid and easily readable displays on almost any surface. E-books may someday actually look like books, made primarily of paper, only with changing, dynamic pages.
