  • Patent number: 8501023
    Abstract: An apparatus for use with a digital micromirror device includes a hinge layer that is disposed outwardly from a substrate. The hinge layer including a hinge that is capable of at least partially supporting a micromirror that is disposed outwardly from the hinge. In one particular embodiment, the hinge and the substrate are separated by a first air gap. The device also including a first hinge support that is disposed outwardly from the substrate and inwardly from at least a portion of the hinge layer. The first hinge support being capable of transmitting a voltage to the hinge. At least a portion of the hinge support coupled to at least the portion of the hinge layer. In one particular embodiment, the first hinge support is formed in a process step that is different than a process step that forms the hinge layer.

  • Patent number: 7911679
    Abstract: An apparatus for use with a digital micro-mirror 100 includes a hinge 116 disposed outwardly from a substrate 102. The hinge 116 is capable of at least partially supporting a micro-mirror 104 disposed outwardly from the hinge 116. The micro-mirror 104 is capable of being selectively transitioned between an on-state position and an off-state position. In one particular embodiment, the hinge 116 comprises a substantially flat profile for at least a portion of the hinge 116 disposed between a first hinge post 108 of the hinge 116 and a mid-point of the hinge 116. The apparatus also includes a plurality of process control voids formed within a conductive layer 120 disposed inwardly from the hinge 116. In one particular embodiment, the substantially flat profile is at least partially created from the plurality of process control voids.

  • Patent number: 7106491
    Abstract: A system and method of providing a micromirror pixel 400 that is highly resistant to bright failure states. The micromirror 400 uses an asymmetric yoke 402 to ensure the mirror is only attracted to the address electrode in one rotation direction. The landing mechanism on the other side of the torsion binge axis also is altered to allow the pixel to over rotate in the “off” direction. The over rotation ensures that light reflected by the mirror when in the off direction will miss the projection lens pupil, allowing the corresponding pixel to remain dark in both an operational and failed state.

  • Patent number: 7106492
    Abstract: An apparatus for use with a digital micro-mirror includes a hinge disposed outwardly from a substrate and capable of at least partially supporting a micro-mirror disposed outwardly from the hinge. The micro-mirror capable of being selectively transitioned between an on-state position and an off-state position based at least in part on a bias voltage received by a conductive conduit. The apparatus also includes a conductive layer disposed inwardly from the at least one micro-mirror. In one particular embodiment, the conductive layer enables a conductive path for the bias voltage substantially inwardly from a periphery of the micro-mirror.
