  • Patent number: 9274333
    Abstract: This application relates to a display including a first layer of material including a first aperture having at least one side, a first substrate separated from the first layer of material by a gap, where the first substrate is arranged to pass through a portion of light emitted from a light source into the gap. The display further includes a movable shutter arranged within the gap, where the shutter is movable to at least a first position and a second position, to obstruct passage of the portion of light through the first aperture at the first position. The movable shutter has a first edge, and in the first position, the movable shutter is aligned with the first aperture such that the first edge extends a first length past the at least one side of the first aperture.

  • Patent number: 8526096
    Abstract: The invention relates to a spatial light modulator including a substrate having a surface and a modulation assembly coupled to the substrate including a modulation element and a compliant beam. The modulation assembly is configured to limit the bending of the compliant beam towards an opposing surface that would otherwise be caused by inherent stresses within the compliant beam. The invention also relates to a method of manufacturing a spatial light modulator including the steps of forming and releasing a modulation assembly that has a modulation element and a compliant beam formed in a pre-release position to have an intended inherent stress state. As a result of the stress state in the compliant beam, upon release of the compliant beam, the compliant beam bends into a rest position which is different than the pre-release position, where the rest position is based in part on the intended inherent stress state.
