Electronic-ink based display system employing a plurality of RF-based activator modules in wireless communication with a plurality of remotely-updateable electronic display devices, each employing an electronic ink layer integrated within a stacked architecture

摘要

An electronic-ink based display system for displaying graphical indicia within the space of a physical environment. The system includes a plurality of RF-based activator modules installed within the space of the physical environment, and a plurality of remotely-updateable electronic display devices installed within the space of the physical environment. Each RF-based activator module sends and transmits electromagnetic signals within the space of the physical environment. Each remotely-updated electronic display device employs an addressable display assembly including a layer of electronic ink including a bi-stable non-volatile imaging material. The device includes an integrated circuit structure having a storage element for storing instructions, programs and data, and a programmed processor in electrical communication with the addressable display assembly and an antenna structure. A signal transmitting structure transmits signals from the antenna structure to the remote activator module. A signal receiving structure receives electromagnetic signals from the remote activator module, using the antenna structure. An on-board battery power structure, operably connected to the integrated circuit structure, supplies electrical power the integrated circuit structure. The antenna structure, integrated circuit structure, signal transmitting structure, signal receiving structure, on-board battery power structure are arranged and stacked together behind and within the spatial extent of the addressable display assembly so as to form the remotely-alterable electronic-ink based display device having a stacked construction.
