Flat panel displays used in laptops and personal organizers are increasing both in resolution and in size, but, for applications requiring larger areas, such as newspapers, these expensive technologies are less suitable. Bach et al. describe one approach toward the development of electronic paper in which they use a textured, transparent conducting electrode decorated with electrochromic molecules and encapsulated with a counterelectrode as the active switching elements. Application of a small bias (a couple of volts) to the electrode changes the optical properties of the chromophores from light to dark to form alphanumeric and text displays on a suitably patterned electrode. Moreover, the switching is relatively rapid, taking only tens of milliseconds. This approach may lead to fast, low-power consumption electronic paper displays. — ISO
