A process for creating an electronically addressable display includes
multiple printing operations, similar to a multi-color process in
conventional screen printing. In some of the process steps, electrically
non-active inks are printed onto areas of the receiving substrate, and in
other steps, electrically active inks are printed onto different areas of
the substrate. The printed display can be used in a variety of
applications. This display can be used as an indicator by changing state
of the display after a certain time has elapsed, or when a certain
pressure, thermal, radiative, moisture, acoustic, inclination, pH, or
other threshold is passed. In one embodiment, the display is incorporated
into a battery indicator. A sticker display is described. The sticker is
adhesive backed and may then be applied to a surface to create a
functional information display unit. This invention also features a
display that is both powered and controlled using radio frequencies. It
describes a complete system for controlling, addressing, and powering a
display. The system includes an antenna or antennae, passive charging
circuitry, and active control system, a display, and an energy storage
unit. There is also a separate transmitter that provides the remote power
for the display. The system is meant to be used anywhere it is useful to
provide intermittent updates of information such as in a store, on a
highway, or in an airport. A tile-based display allowing a modular system
for large area display is created using a printable display material.
