Abstract

This disclosure provides systems, methods, and apparatus for display device including a dielectric stack positioned between a first electrically conductive layer and a second movable electrically conductive layer. In one aspect, the dielectric stack includes alternating dielectric layers of high and low indices of refraction. By controlling the refractive indices and thicknesses of layers within the dielectric stack, the display device's states of light reflection may be reversed, such that light is reflected when the movable layer is positioned in proximity to the first electrically conductive layer.
