Abstract:
1. A wireless electronic-ink based display device supported in packaging, 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 clear layer; a power source module including an electro-chemical battery; a power management module for managing the power levels within said wireless electronic-ink display device; a power switching module, arranged between said power source module and said power management module, and being automatically responsive to a change in at least one predefined state of device configuration; wherein said change in at least one predefined state of device configuration includes changes in the states of device configuration selected from the group consisting of: (i) said wireless electronic-ink display device being removed from said packaging, causing said power switching module to be configured into an electrically conductive arrangement, and capable of conducting electricity from said power source module to said power management module; and (ii) an object affixed to said power switching module, being removed or moved away from a predetermined position, causing said power switching module to be configured into an electrically conductive arrangement, and capable of conducting electricity from said power source module to said power management module; wherein said power switching module prevents leakage, drainage or discharge of said electro-chemical battery until the change in predefined state of device configuration occurs.
