  • Patent number: 12140764
    Abstract: Disclosed herein are systems and methods for providing waveguide display devices utilizing overlapping integrated dual axis (IDA) waveguides. One embodiment includes a waveguide display device including: a first input image source providing first image light; a second input image source provide second image light; a first IDA waveguide; and a second IDA waveguide. The first IDA waveguide and the second IDA waveguide may include an overlapping region where a first two-dimensionally expanded first image light, a second two-dimensionally expanded first image light, a first two-dimensionally expanded second image light, and a second two-dimensionally expanded second image light is ejected towards an eyebox. Advantageously, resolution may be enhanced and field of view may be expanded through the use of overlapping IDA waveguides.

  • Patent number: 12092914
    Abstract: Systems for the manufacturing of waveguide cells in accordance with various embodiments can be configured and implemented in many different ways. In many embodiments, various deposition mechanisms are used to deposit layer(s) of optical recording material onto a transparent substrate. A second transparent substrate can be provided, and the three layers can be laminated to form a waveguide cell. Suitable optical recording material can vary widely depending on the given application. In some embodiments, the optical recording material deposited has a similar composition throughout the layer. In a number of embodiments, the optical recording material spatially varies in composition, allowing for the formation of optical elements with varying characteristics. Regardless of the composition of the optical recording material, any method of placing or depositing the optical recording material onto a substrate can be utilized.

  • Publication number: 20240302656
    Abstract: Systems and methods for generating head-up displays (HUDs) using waveguides incorporating Bragg gratings in accordance with various embodiments of the invention are provided. The term HUD is typically utilized to describe a class of displays that incorporates a transparent display that presents data without requiring users to look away from their usual viewpoints. HUDs can be incorporated in any of a variety of applications including (but not limited to) vehicular and near-eye applications, such as googles, eyewear, etc. HUDs that utilize planar waveguides that incorporate Bragg gratings in accordance with various embodiments of the invention can achieve significantly larger fields of view and have lower volumetric requirements than HUDs implemented using conventional optical components.

  • Publication number: 20240255760
    Abstract: An optical display comprises: a first waveguide comprising a first surface and a second surface, an input coupler, a fold grating, and an output grating. The input coupler receives collimated first wavelength light from an Input Image Node causes the light to travel within the first waveguide via total internal reflection between the first surface and the second surface to the fold grating. The fold grating provides pupil expansion in a first direction directs the light to the output grating via total internal reflection between the first surface and the second surface. The output grating provides pupil expansion in a second direction different than the first direction and causes the light to exit the first waveguide from the first surface or the second surface. At least one of the input coupler, fold grating and output grating is a rolled k-vector grating, and the fold grating is a dual interaction grating.

  • 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.
