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.
