Remotely-alterable radio-frequency (RF) powered electronic display label employing an electronic ink layer integrated within a stacked-layer architecture

摘要

A remotely-alterable electronic-ink based display label employing an addressable display assembly including a layer of electronic ink which includes a bi-stable non-volatile imaging material. The display label includes an integrated circuit layer having a storage element for storing instructions, programs and data, and a programmed processor in electrical communication with the addressable display assembly and a data antenna layer. A signal transmitting layer transmits signals from the data antenna layer to a remote activator module. A signal receiving layer receives electromagnetic signals from the remote activator module, using the data antenna layer. A power antenna layer, operably connected to a power converter, supplies electrical power to the integrated circuit layer, for converting received RF-power signals into electrical power signals and storing electrical charge for solely powering the programmed processor to process instructions and data to determine the graphical indicia to be displayed by the addressable display assembly and to activate the addressable display assembly to display the determined graphical indicia. The data antenna layer, power antenna layer, integrated circuit layer, signal transmitting layer, and signal receiving layer are arranged and stacked together behind and within the spatial extent of the addressable display assembly so as to form the remotely-alterable electronic-ink based display label having a stacked-layer construction.
