Abstract
A micro-electromechanical bistable shutter display device is provided capable of being implemented for both small screen, high resolution devices and for large billboard-type displays. The micro-electromechanical shutter assembly has bi-stability characteristics which allow the use of only a holding voltage to maintain an image. The micro-electromechanical shutter assembly includes a shutter having petal-like shutter segments covering reflective or transmittive films. To expose the film in a particular shutter assembly, its shutter segments are moved from the horizontal to a vertical position using electrostatic attraction forces to “collapse” the torsionally-hinged shutter segments. The shutter assembly can have a number of segments, as long as the resulting shutter assembly shape can be stacked to form a dense 2D array.
