Abstract
A flat panel display is proposed wherein each pixel contains two membranes, covering the entire pixel area, which under the force of electrostatic attraction rotate from their original position parallel to the substrate plane into a final position normal to the substrate plane, thereby altering the optical state of the pixel. The electrostatic force is applied only to narrow conductive strips placed on the membrane sides and rotates the membranes around torsion hinges attached to the membranes through flexible and conductive belts. Two membranes per pixel, turned toward each other in their upright position, increase the viewing angle of the display. Further increase of the viewing angle is based on making both the bottom membrane surface and the pixel interior black. Another disclosed feature in the pixel design is placement of an additional pillar located in the area of the membrane hinges to both facilitate the membrane rotation under the electrostatic force and hold the membrane in the upright position.
