Abstract: Emissive micro-pixel spatial light modulators with non-telecentric emission are introduced. The individual light emission from each multi-color micro-scale emissive pixel is directionally modulated in a unique direction to enable application-specific non-telecentric emission pattern from the micro-pixel array of the emissive spatial light modulator. Design methods for directionally modulating the light emission of the individual micro-pixels using micro-pixel level optics are described. Monolithic wafer level optics methods for fabricating the micro-pixel level optics are also described. An emissive multi-color micro-pixel spatial light modulator with non-telecentric emission is used to exemplify the methods and possible applications of the present invention: ultra-compact image projector, minimal cross-talk 3D light field display, multi-view 2D display, and directionally modulated waveguide optics for see-through near-eye displays.

Abstract: Split exit pupil (or split eye-box) heads-up display (HUD)systems and methods are described. The described HUD system methods make use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall HUD volumetric aspects. A HUD module utilizes a high brightness small size micro-pixel imager to generate one or more HUD virtual images with a one or a plurality of given viewing eye-box segment sizes. When integrated together into a HUD system, a multiplicity of such HUD modules displaying the same image would enable such an integrated HUD system to have an eye-box size that is substantially larger than the eye-box size of a HUD module. The resultant integrated HUD system volume is substantially volumetrically smaller than a HUD system that uses a single larger imager. Furthermore, the integrated HUD system can be comprised of a multiplicity of HUD modules to scale the eye-box size to match the intended application while maintaining a given desired overall HUD system brightness.

Abstract: Wearable augmented reality display systems are provided. One or a plurality of emissive display elements are embedded in the bridge area of an eyeglass frame. The lenses are provided with a set of transmissive diffractive optical elements and partially reflective diffractive optical elements. The display outputs are directed toward the lens elements whereby the diffractive elements in turn direct the outputs toward the eye-boxes of the viewer.

Abstract: A split exit pupil heads-up display (HUD) system and method. The HUD system architecture makes use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall volumetric aspects. A single HUD module utilizes a micro-pixel imager to generate a HUD virtual image with a given viewing eye-box size. When integrated together into a single HUD system, a multiplicity of such a HUD modules displaying the same image enables an integrated HUD system to have an eye-box size that equals the same multiple of the eye-box size of a single HUD module. The brightness of the integrated HUD system is maintained while the eye-box size becomes multiple size of the eye-box of a single module. The integrated HUD system can be comprised of multiplicity of single HUD modules to scale the eye-box size to match the intended application while maintaining system brightness.

Abstract: A system for near-eye display applications. A lens is provided with a beam-splitting interface horizontally along the width of the lens. Two display devices per lens are provided and disposed on the perimeter surface of the lens opposing an overlapped, prismatic facet optics assembly which balances aberration introduced by the slight symmetry break in the lens.
