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.

Abstract: A microelectromechanical systems (MEMS) device includes a base plate including a first electrode and a second electrode and a top layer. The MEMS device also includes a perforated hinge plate supporting the top layer. The perforated hinge plate includes first and second flexural arms permitting the perforated hinge plate and the top layer to move relative to the base plate. The perforated hinge plate has a first perforation that includes the first electrode and has a footprint that is larger than a footprint of the first electrode, and the perforated hinge plate has a second perforation that includes the second electrode and has a footprint that is larger than a footprint of the second electrode. Additionally, the MEMS device includes a first support post to which the first flexural arm is connected and a second support post to which the second flexural arm is connected.

Abstract: A phase light modulator includes a base plate, a mirror, a perforated hinge plate, and first second support posts. The perforated hinge plate supports the mirror. The perforated hinge plate has first and second flexural arms. The perforated hinge plate is configured to move toward or away from the base plate based on application of a potential difference between the base plate and the perforated hinge plate. The first flexural arm is connected to the first support posts, and the second flexural arm is connected to the second support post.

Abstract: A device includes at least one processor configured to partition a source image including image components into sub-images, each including a corresponding image component of the image components, and process each sub-image to produce a target image to be projected for each sub-image of the sub-images. The device also includes one or more light sources coupled to the at least one processor and configured to project an incident light, and a phase projection-based display device coupled to the at least one processor and optically coupled to the one or more light sources and configured to modulate, based on the target image of each sub-image, the incident light to separately project the sub-images.

Abstract: In an example, a system includes a digital micromirror device (DMD). The DMD includes a hinge and one or more spring tips coupled to the hinge, where the hinge is configured to tilt toward a raised address electrode. The DMD includes a micromirror including a recessed mirror shelf and a reflective surface, where the recessed mirror shelf is coupled to the hinge, and where the recessed mirror shelf is configured to contact at least one of the one or more spring tips responsive to the hinge tilting toward the raised address electrode.
