Abstract: A digital micromirror device comprises an array of micromirror pixels, the array comprising a first micromirror pixel and a second micromirror pixel. The first micromirror pixel comprises a hinge, where the hinge is configured to tilt toward a first raised address electrode and toward a second raised address electrode. The first micromirror pixel also comprises a first micromirror coupled to the hinge, where the first micromirror has a sculpted edge. The second micromirror pixel comprises a second micromirror, where a first gap between a first point on the sculpted edge and a nearest point to the first point on the second micromirror is larger than a second gap between a second point on the sculpted edge and a nearest point to the second point on the second micromirror.

Abstract: A system includes a hinge structure. The hinge structure includes four support posts and four hinges, each hinge coupled to an edge of a support post and to a plate of the hinge structure, where each hinge includes two 90° turns. The system also includes a mirror coupled to the hinge structure and an electrode structure coupled to the hinge structure.
