Abstract
An electronic information display system for installation across wholesale/distribution channels. The system includes a plurality of electronic-ink display labels, associated with a plurality of manufactured items. One or more activation modules are provided across the wholesale/retail distribution channels, for transmitting electromagnetic data signals to the electronic-ink display labels and providing instructions to the updateable electronic-ink display labels. Each electronic-ink display label employs an addressable display assembly including a layer of electronic ink including a bi-stable non-volatile imaging material. The electronic-ink display label includes an integrated circuit structure having a storage element for storing instructions, programs and data, and a programmed processor in communication with storage element. A signal receiving structure receives electromagnetic signals from the activation module, using the antenna structure. The electronic-ink display label displays graphical indicia representing information which changes as the associated manufactured item moves through the wholesale/retail distribution channels.
