Abstract:
1. A display device, comprised of two-dimensional matrix of pixels, each pixel representing an optical electromechanical shutter comprised of: a substrate; two membranes placed on four pillars parallel to and above the substrate plane and covering the entire pixel area, each of said two membranes occupying a half of the pixel area, wherein longer sides of said two membranes are attached to two of said four pillars through torsion hinges at the opposite sides of the pixel area, while said two membranes are composed of the following elements: second conducting electrode placed on said substrate underneath said first conducting electrode on said membrane and made as a stripe parallel to said first conducting electrode, so that under application of appropriate potential difference between said first and second conducting electrodes said two membranes can switch electro-statically to the position normal to said substrate plane, thereby changing the pixel optical state, wherein said two membranes in said position normal to said substrate plane are parallel to each other, face each other and located at the opposite sides of each pixel area thereby producing the enclosed pixel interior and thus making viewing angle of every pixel independent of neighboring pixels; appropriate set of conductive lines connected to said first and second conductive electrodes for application of a voltage to the pixel matrix.
