Patent ID: 8643937

Claim:
A digital nano-mirror device (DND) comprising: a nano-mirror; and an actuating module configured to move the nano-mirror in an upward and/or downward position, wherein the actuating module comprises a cantilever mounted to a fixed structure, wherein the cantilever comprises: a first cantilever segment extending in a first direction, the first cantilever segment having a first end connected to the nano-mirror and a second end connected to a second cantilever segment; a third cantilever segment extending in the first direction, the third cantilever segment having a first end connected to the second cantilever segment and a second end connected to a fourth cantilever segment, wherein the third cantilever segment is pivotally mounted to the fixed structure at a pivot location such that the second cantilever segment is disposed on a first side of the pivot location and the fourth cantilever segment is disposed on a second side of the pivot location; a first electrode configured to actuate the second cantilever segment and substantially overlapping the second cantilever segment on the first side when viewed in a direction perpendicular to a surface of the nano-mirror; and a second electrode configured to actuate the fourth cantilever segment and substantially overlapping the fourth cantilever segment on the second side when viewed in the direction perpendicular to the surface of the nano-mirror.
