1. A wireless electronic-ink based signage device employing thermally-insulating packaging for cold outdoor-weather applications, comprising:

  • an addressable electronic-ink based display module including a layer of bi-stable display medium disposed between a backplane driving structure and an electrically-conductive optically-clear layer, and providing a display surface on which to display graphics;

    a power source module including an electro-chemical battery;

    a processor for controlling operations within said wireless electronic-ink display device;

    a RF transceiver for transmitting and receiving RF data packet signals;

    an RF antenna structure, an impedance matching structure interfacing said RF transceiver and said RF antenna structure;

    a power management module for managing the power levels within said wireless electronic-ink display device;

    a printed circuit board (PCB) structure having first and second sides;

    said power source module, said processor, said RF transceiver, and said power management module being mounted on the first side of said PCB structure;

    said addressable electronic-ink based display module being mounted on the second side of said PCB structure; and

    a thermal-insulation weather-sealed packaging provided about said addressable electronic-ink based display structure and said PCB structure.
