  • Patent number: 12222499
    Abstract: Methods and apparatus for eye-glow suppression in waveguide systems is disclosed herein. Some embodiments of the methods and the apparatus include a source of image modulated light; a waveguide having an eye-facing surface and an external surface facing the outside world; an input coupler for coupling the light into a total reflection internal path in the waveguide; at least one grating for providing beam expansion and extracting light from the waveguide towards an eyebox; a polymer grating structure comprising a modulation depth and a grating pitch. The modulation depth is greater than the grating pitch across at least a portion of the polymer grating structure. Advantageously, the polymer grating structure is configured to diffract light entering the waveguide from the outside world or stray light generated within the waveguide away from optical paths that are refracted through the external surface into the outside world.

  • Patent number: 12210153
    Abstract: Waveguides and waveguide displays having a layer for blocking non-image light (i.e. haze) that could otherwise reduce contrast and degrade color gamut and uniformity, while providing high transmission to external light are provided. Many waveguides and displays incorporate at least one light control layer applied to at least one external surface of a waveguide supporting at least one grating and overlapping at least a portion of the at least one grating, to divert or block scattered light from the set of gratings that might otherwise enter said eyebox.

  • Patent number: 9803847
    Abstract: A modular light emitting diode (LED) mounting configuration is provided including a light source module having a plurality of pre-packaged LEDs arranged in a serial array. The module includes a heat conductive body portion adapted to conduct heat generated by the LEDs to an adjacent heat sink. As a result, the LEDs are able to be operated with a higher current than normally allowed. Thus, brightness and performance of the LEDs is increased without decreasing the life expectancy of the LEDs. The LED modules can be used in a variety of illumination applications employing one or more modules.
