The growing market for flexible electronics devices is asking for reduction of manufacturing process complexity. One way to reduce complexity is to decrease the number of single components of a device by using integrated modules, i.e. device components providing multiple functions. In this article, the concept of a self-powered electrochromic graphics display device is demonstrated. The device is based on a three electrode system comprising an electrochromic electrode, a battery anode and a battery cathode, all in contact with a common electrolyte. The electrochromic electrode can be charged and discharged directly when connected to either the anode or cathode. Such a self-powered display integrates the functions of both a display and a battery. As part of a flexible electronics device, a self-powered display would be able to power other components, such as driver electronics.
