Abstract
An electrostatic memory micromirror display system including an array of electrostatic memory and display assemblies each including a memory and display element having a mirror surface and a conductive medium; a support device for movably mounting the memory and display element; and a set of electrodes including at least first and second electrodes proximate the conductive medium; and means for selectively applying a voltage to the first electrode of predetermined ones of the memory and display assemblies to establish an electrostatic field between the first electrode and the conductive medium to urge the associated display element from a first position toward a second position and for applying a voltage to the second electrode of the assemblies to establish an electric field between the second electrode and the conductive medium to set the memory and display element in the second position.
