Abstract

This disclosure provides systems, methods and apparatus related to an electromechanical display device. In one aspect, an analog interferometric modulator (AIMOD) includes a reflective display pixel having a movable element disposed between first and second electrodes. The movable element includes a third electrode embedded within a deformable layer and a reflector. The movable element is moved to different positions between first and second electrodes, with different positions corresponding to different reflected colors from the AIMOD. In another aspect, the reflector is coupled to, but spaced apart from, the deformable layer, thereby decoupling the mechanical and optical properties of the movable element. In another aspect, the need for a bending region in the reflector is eliminated, providing for increased fill factor. In another aspect, the reflector may include a dielectric layer having substantially identical metal layers above and below, so as to provide increased rigidity to the reflector.
