Abstract: A method, an apparatus, and a computer program product for modulating optics in a display are provided. An apparatus forms a plurality of zone plates in a liquid crystal using electric fields. Each zone plate has a center, and the centers are aligned along a first axis of the display. The apparatus moves the plurality of zone plates in a first direction along a second axis of the display different from the first axis of the display, while maintaining alignment of the centers of the plurality of zone plates along the first axis. Such movement is provided through repositioning of electric fields through the liquid crystal.

Abstract: A method for reducing bit-depth of image data for an imaging device includes receiving an image frame for display to the imaging device. The method additionally includes applying temporal error diffusion for the image frame to produce a plurality of image subframes, wherein temporal errors generated in one subframe of the image frame are passed to a next subframe of the image frame for temporal error diffusion. The method also includes applying spatial error diffusion to remaining temporal errors from the temporal error diffusion of the image frame.

Abstract: The various embodiments include a near-eye display having a transmissive display and a diffractive micro-lens array. The transmissive display may be positioned relative to the diffractive micro-lens array so that the distance between the transmissive display and the diffractive micro-lens array is be approximately equal to focal length of the diffractive micro-lens array. The transmissive display may also be positioned relative to the diffractive micro-lens array so that a percentage of light emitted from the transmissive display is diffracted by the micro-lens array and collimated into focus on a retina of a human eye. The transmissive display may be further positioned relative to the diffractive micro-lens array so that light from a real world scene passes through transparent portions of the transmissive display and is diffracted by the micro-lens array out of focus of the human eye.
