Abstract:
1. An apparatus comprising an electromechanical image display, the electromechanical image display comprising: a box-structure defining a plurality of cups arranged in a row and column matrix; an axle for each column in the matrix; each cup in the plurality of cups: at least two electric-field-generating conducting plates in each cup in the plurality of cups; a display element for each cup, said display element comprising: wherein the axle for each column is non-rotatably attached and passes through two of the four sidewalls of each cup in one column; wherein one display element is rotatably placed on the axle within the four sidewalls of each cup in its column; and wherein when the electric-field-generating conducting plates in any one cup have an electric charge, said electric charge causes the electret within that cup to rotate to a fixed position such that two faces of the parallelepiped are displayed facing outward at the open end.
