Abstract
A microelectromechanical system (MEMS) is provided. In one embodiment, the MEMS includes a transparent substrate, and a plurality of interferometric modulators. The plurality of interferometric modulators includes an optical stack coupled to the transparent substrate, in which the optical stack includes a first light absorbing area. The plurality of interferometric modulators further includes a reflective layer over the optical stack, and one or more posts to support the reflective layer. Each of the one or more posts includes a second light absorbing area integrated in the post.
