Dynamically variable graphic material using electrostatically attracted particles

摘要

Dynamically-variable graphic displays, including a panel comprised of colored microspheres, each a single pixel with an embedded electrical charge; one or more electrodes capable of receiving an electrical charge, each electrode situated so that it can interact with at least one of said microspheres; an energy source connected to the electrodes via conductive elements capable of changing the polarity of said electrodes, such change in polarity causing the microspheres to move to change the color displayed to a viewer; and a substrate. Also included within the invention are dynamically-variable graphic display panels that enable one-way graphics through distribution of pixels to create image and silhouette patterns, wherein the image pattern is visible from the front of the panel under conditions of illumination, and wherein the silhouette pattern creates a substantially transparent area of clear vision from the back of the display panel through the panel.

主权项

1. A dynamically variable one-way graphic display comprising an arrangement of:
a substrate of dielectric material or dielectric coated material, a plurality of particles, each particle comprising one or more colored sectors, each sector associated with an embedded electromagnetic charge; one or more electrodes bonded to the substrate, each having a variable electromagnetic charge, wherein each of said electrodes faces at least one corresponding colored sector on a particle, said corresponding sector on said particle being one of said plurality of sectors, each of said one or more electrodes configured to interact with said corresponding colored sector on said particle, wherein interacting includes moving said particle; and an energy source connected to the one or more electrodes via conductive elements, for changing the variable electromagnetic charges of the one or more electrodes.
