An electromechanical display panel that includes at least two spatially
separated plates. Between the at least two spatially separated plates is
a suspended porous movable film having a pore area, wherein the pore area
comprises less than 50% of surface area of the porous movable film. The
electromechanical display panel also includes a means for moving the
porous movable film between the at least two spatially separated plates
to cause selective light modulation.
