  • 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: 9135868
    Abstract: A direct-view display includes an array of MEMS light modulators and a control matrix formed on a transparent substrate, where each light modulator can be driven into at least two states, and a controller for controlling the states of each light modulator in the array. The control matrix transmits data and actuation voltages to the array. The controller includes an input, a processor, a memory, and an output. The input receives image data encoding an image frame for display. The processor derives a plurality of sub-frame data sets from the image data, where each sub-frame data set indicates desired states of light modulators in multiple rows and multiple columns of the array. The memory stores the plurality of sub-frame data sets. The output outputs the plurality of sub-frame data sets according to an output sequence to drive light modulators into the states indicated in the sub-frame data sets.

  • Patent number: 7898714
    Abstract: This invention relates to display apparatuses having an array of light modulators for transmissively displaying an image and a reflective aperture layer defining a plurality of apertures, for reflecting light not passing through apertures in the reflective aperture layer away from the array. The reflective aperture layer is formed on a first substrate and positioned adjacent the array. The image is formed by modulating light passing through the apertures in the reflective aperture layer. A light guide, separated from the first substrate by a gap, may guide light towards the reflective aperture layer. A layer of low-refractive index material may be positioned on a side of the reflective aperture layer opposite the array.
