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

An electronic-ink based display system for displaying graphical indicia within the space of a physical environment, said electronic-ink based display system comprising:

• (A) a plurality of RF-based activator modules installed within the space of said physical environment,
• wherein each said RF-based activator module sends and transmits electromagnetic signals, over the RF band, within the space of said physical environment;
• and
• (B) a plurality of remotely-updateable electronic display devices installed within the space of said physical environment,
• wherein each said remotely-updated electronic display device includes:
• (B1) an addressable display assembly including a layer of electronic ink including a bi-stable non-volatile imaging material disposed between an activation layer and a transparent electrode layer located above said layer of electronic ink, for so activating said layer of electronic ink at particular locations to display graphical indicia on the surface of said addressable display assembly, wherein said layer of electronic ink does not require electrical power to maintain the display of said graphical indicia;
• (B2) at least one antenna structure for sending and/or receiving electromagnetic signals carrying information corresponding to one of instructions, programs, data or graphical indicia to be displayed by said addressable display assembly;
• (B3) an integrated circuit structure having (i) a storage element for storing said instructions, programs and data, and (ii) a programmed processor in electrical communication with said addressable display assembly and said at least one antenna structure, and using said programs to process said instructions and data for (i) determining the graphical indicia to be displayed by said addressable display assembly at any moment in time, (ii) controlling and coordinating operation of said addressable display assembly, and (iii) generating output signals for instructing said addressable display assembly to display the determined graphical indicia;
• wherein identification information is stored in said storage element, and uniquely identifies said electronic-ink based display device among said plurality of electronic-ink based display devices arranged in said electronic display system, so that at least one said RF-based activator module can send electromagnetic signals to said at least one antenna structure on at least one specified electronic-ink based display device and update one or more of said instructions, programs, data and graphical indicia therein;
• (B4) a signal transmitting structure, operably connected to said integrated circuit structure and said antenna structure, for transmitting electromagnetic signals from said at least one antenna structure, to at least one remote activator module;
• (B5) a signal receiving structure, operably connected to said integrated circuit structure and said antenna structure, for receiving electromagnetic signals from said remote activator module, using said at least one antenna structure;
• wherein said received electromagnetic signals carry information corresponding to said programs, said instructions, said data or said graphical indicia to be displayed by said addressable display assembly;
• and
• (B6) an on-board battery power structure, operably connected to said integrated circuit structure, for supplying electrical power to said integrated circuit structure;
• wherein said addressable display assembly is responsive to electromagnetic signals received from said remote activator module by said at least one antenna structure and said signal receiving structure;
• wherein said integrated circuit structure is responsive to electromagnetic signals received from said remote activator module by said antenna structure and said signal receiving structure;
• wherein said addressable display assembly is responsive to said output signals generated by said programmed processor, to display the determined graphical indicia;
• and
• wherein said at least one antenna structure, said integrated circuit structure, said signal transmitting structure, said signal receiving structure and said on-board battery power structure are arranged and stacked together behind and within the spatial extent of said addressable display assembly so as to form said remotely-alterable electronic-ink based display device having a stacked construction.
