Abstract: This disclosure provides systems, methods and apparatus relating to electromechanical display devices. In one aspect, a multi-stage interferometric modulator (IMOD) can include a movable reflector that can be moved to different positions to produce different reflected colors. The IMOD can include deformable elements that are coupled to a back side of the movable reflector and provide support to the movable reflector. The deformable elements can provide a restoring force that biases the movable reflector to a resting position. The IMOD can include one or more restoring force modifiers that are configured to increase the restoring force when engaged. The restoring force modifiers can be between the movable reflector and the deformable elements such that the deformable elements contact the restoring force modifiers when the movable reflector is displaced to a contacting position.
