In one implementation, a display device includes an array having a plurality of electromechanical pixels disposed on a substrate, each pixel including at least a first display element and a second display element. Each of the first and second display elements interferometrically modulating light by moving a reflective element between a relaxed position spaced apart from the substrate to an actuated position further away from the substrate than the relaxed position by applying a voltage across the reflective element and a stationary electrode. The stationary electrode of each display element is sized to provide actuation of the movable reflective element using the same actuation voltage even though the electrical gap through which the reflective element moves is different within a pixel.

摘要： This disclosure provides systems, methods and apparatus for controlling a mechanical layer. In one aspect, an electromechanical systems device includes a substrate and a mechanical layer positioned over the substrate to define a gap. The mechanical layer is movable in the gap between an actuated position and a relaxed position, and includes a mirror layer, a cap layer, and a dielectric layer disposed between the mirror layer and the cap layer. The mechanical layer is configured to have a curvature in a direction away from the substrate when the mechanical layer is in the relaxed position. In some implementations, the mechanical layer can be formed to have a positive stress gradient directed toward the substrate that can direct the curvature of the mechanical layer upward when the sacrificial layer is removed.
