  • Patent number: 9927615
    Abstract: Some implementations of augmented reality glasses disclosed herein include an eyeglass substrate, two or more display elements, image optics configured for coupling light from the display elements into the eyeglass substrate and beam-splitting optics configured for directing light from the eyeglass substrate towards a viewer's eye and for allowing partial light from the real-world scene to arrive at a viewer's eye. The image optics may include one or more image optics lenses formed in the eyeglass substrate and may be positioned out of a line of sight of the viewer's eye when the viewer is wearing the augmented reality glasses. The image optics may be capable of coupling light from the display elements toward the beam-splitting optics along folded light paths caused by internal reflection within the eyeglass substrate.

  • Publication number: 20160231471
    Abstract: An apparatus may include a first layer having a range of first layer indices of refraction. The range of first layer indices of refraction may include at least two indices of refraction. The apparatus may include a second layer proximate the first layer. The second layer may have a second index of refraction that is outside (e.g., lower than) the range of first layer indices of refraction. An interface between the first layer and the second layer may include an array of microlenses of substantially randomized sizes. The microlenses may include sections of features that are substantially spherical, polygonal, conical, etc. According to some implementations, the first and second layers may be disposed between an array of display device pixels and a substantially transparent substrate, such as a glass substrate, a polymer substrate, etc.

  • Publication number: 20160011340
    Abstract: Some implementations disclosed herein include a dual lens system capable of maintaining a substantially constant color within a well-defined angular range of light incident on a reflective pixel. Each reflective pixel (or subpixel) of a display may include a primary lens and a field lens. The field lens may be positioned at a distance equal to a focal length of the primary lens. Each plane wave of incident light arriving at the primary lens aperture may be focused on a unique location of the focal plane, but may emerge from the field lens within the same range of angles. If a reflective pixel is positioned below the field lens, the reflected color should be substantially the same within a range of viewing angles. The range of angles may be defined by the numerical aperture of the lens system and by black mask material disposed between the reflective pixels or subpixels.

  • Publication number: 20150355454
    Abstract: Various implementations described herein involve multi-state interferometric modulators (MS-IMODs) without dielectric layers capable of affecting optical performance formed on the mirrors. The MS-IMODs disclosed herein may include a novel combination of high refractive index and low refractive index layers in the absorber stack. Some such MS-IMODs include absorber stacks having an absorber layer, a first high-index layer disposed between the absorber layer and the substrate, a low-index layer disposed between the absorber layer and the first high-index layer and a second high-index layer disposed on a side of the absorber layer facing the mirror. The absorber stack and the mirror may define a gap therebetween and may be capable of being positioned in a plurality of positions relative to one another to form a plurality of gap heights. In some implementations, the closest position corresponds with a black state gap height.
