Abstract:
1. A display device, comprising: a two-dimensional matrix of pixels, each pixel comprising: a dielectric bar, substantially normal to said substrate, located beneath each of the two cantilevers at said active side and extending over a display area in the direction parallel to said active side, said bar having on its wall a second electrode facing said active side and extending through the display device thereby forming a column line of the display device; a hinge located at each of two cantilever corners on said active side of each of said two cantilevers and made from a same material as the cantilevers to hold the cantilevers attached to corresponding ones of said dielectric bars, said hinges providing conductance from said first electrode of the pixel to an electrode common to all the pixels in the display device and facilitating electro-static cantilever rotation around said hinges from an original cantilever position parallel to said substrate plane into a position normal to said substrate plane; a third electrode, placed on the substrate, as a metal line at said active side adjacent, and parallel, to said dielectric bar to form a first capacitance between said first electrode of the pixel and said third electrode; an additional metal line, disposed perpendicular to said column lines on said dielectric bars and connecting said third electrodes in one row, while keeping said third electrodes electrically disconnected from other rows, to form the row lines of the display; and a top conducting and optically transparent layer disposed on a bottom surface of a transparent display cover at a known distance from a plane of said cantilevers, said distance being sufficient to accommodate said cantilever in its position normal to the substrate plane, said top conducting layer operating as a fourth electrode forming a second capacitance, said second capacitance between said top conducting layer and said first electrode, wherein rotation around said hinges changes the position of the cantilever from a position parallel to the substrate to a position normal to said substrate.
