Abstract
Methods and apparatus for providing light in an interferometric modulator device are provided. In one embodiment, a microelectromechanical system (MEMS) is provided that includes a transparent substrate and a plurality of interferometric modulators. The interferometric modulators include an optical stack coupled to the transparent substrate, a reflective layer over the optical stack, and one or more posts to support the reflective and to provide a path for light from a backlight for lighting the interferometric modulators.
