Abstract
A wireless electronic-ink display device supported in packaging, and employing a power switching mechanism which operates to prevent leakage, drainage or discharge of the electro-chemical battery until a change in predetermined state of configuration occurs. The wireless electronic-ink based display device comprises (i) a power source module with an electro-chemical battery, (ii) a power management module for managing the power levels within the wireless electronic-ink display device, and (iii) a power switching module, arranged between the power source module and the power management module, and automatically responsive to a change in at least one predefined state of device configuration, to prevent leakage, drainage or discharge of the electro-chemical battery until a change in predetermined state of configuration occurs. In the illustrative embodiment, wherein the power switching module comprises a reed switch arranged in such a manner to cause the power switching module to be configured into an electrically conductive arrangement, and capable of conducting electricity from the power source module to the power management module, when the wireless electronic-ink display device is removed from its packaging.
