  • Patent number: 11681150
    Abstract: An optical subsystem of a near-eye display system provides for projecting light of a virtual image of image content to an eye location, and provides for collecting light of the virtual image onto an exit pupil on a surface proximate to an outer surface of an eye when at the eye location. A subpupil modulator within an aperture in cooperation with the optical subsystem provides for forming a plurality of subpupils within the exit pupil, and provides for less than all of the light of the virtual image associated with one or more less than all of the plurality of subpupils to be projected to the eye location. In various independent aspects: at least two subpupils overlap by at least 20 percent; and the intensities of the subpupils are individually and independently controlled.

  • Patent number: 11681155
    Abstract: A micro-electromechanical structure for modulating light beams includes multiple asymmetric deformable diffractive elements, each having an L-shaped cross section, split pedestal and flexible reflective member. The reflective member has an elongated shape, and a supported part and unsupported part. The split pedestal extends along the long dimension of the supported part of the reflective member and is anchored to a substrate which supports one or more electrodes or serves as an electrode. The diffractive element is movable between a non-energized position wherein the diffractive element acts to reflect a beam of light as a planar mirror, to an energized position wherein upon application of an electrostatic force, the diffractive element flexes independently about an axis parallel to the long dimension of each reflective member to vary a curvature of the reflective member to form a blazed grating.

  • Patent number: 11681164
    Abstract: An electronic contact lens contains electrical components connected by an electrical interconnect. The electrical interconnect has a flat body, with electrical conductors running length-wise along the body. The flat body is oriented perpendicular rather than parallel to the inner and outer surfaces of the contact lens to reduce a visible profile of the interconnect, reducing the amount of light blocked from entering the eye. The body has a curvature shaped to conform to the curvature of the contact lens. As examples, the interconnect may be connected with an electrical component using a tab perpendicular to the flat body of the interconnect, or by forming an edge connection with electrical contacts of the component located along an edge of the component, or through one or more exposed vias formed on the component.

  • Patent number: 11681166
    Abstract: A wideband electro-absorption modulating (EAM) device is configured to include a ground shield that functions to minimize the spread of an applied AC voltage beyond the limits of the modulator's electrode. The ground shield includes a grounding electrode disposed in a spaced-apart relationship with the modulator electrode along the ridge of the EAM structure, and a grounding termination used to couple the grounding electrode to a suitable ground location. The ground location may be either on-chip (such as the DC ground of the modulator itself) or off-chip (via an off-chip capacitor, with a wirebond connecting the grounding electrode to the capacitor). The use of a ground shield mitigates the effects that changes in the data rate have on effective length of the modulator as seen by the applied data signal.

  • Patent number: 11681192
    Abstract: A display device capable of performing image processing is provided. Each pixel is provided with a memory circuit, and desired correction data is held in the memory circuit. The correction data is calculated in an external device and written into each pixel. The correction data is added to image data owing to capacitive coupling, and the resulting data is supplied to a display element. Thus, a corrected image can be displayed with the display element. The correction enables image upconversion or can compensate for an image quality reduction due to characteristics variations of transistors included in pixels.

  • Patent number: 11681193
    Abstract: Bright ambient light can wash out a virtual image in a conventional augmented reality device. Fortunately, this problem can be prevented with a variable electro-active beam splitter whose reflect/transmit ratio can be varied or switched on and off rapidly at a duty cycle based on the ambient level. As the ambient light gets brighter, the beam splitter's transmit/reflect ratio can be shifted so that the beam splitter reflects more light from the display and transmits less ambient light to the user's eye. The beam splitter can also be switched between a highly reflective state and a highly transmissive state at a duty cycle selected so that the eye spends more time integrating reflected display light than integrating transmitted ambient light. The splitting ratio and/or duty cycle can be adjusted as the ambient light level changes to provide the optimum experience for the user.

  • Patent number: 11681194
    Abstract: Various embodiments set forth liquid crystal (LC) patterning control systems in which LCs are aligned using locally applied magnetic fields. The index of refraction experienced by light propagating through an anisotropic LC is dependent on orientation. As a result, a phase difference may be imparted to an optical beam that is passed through, or reflected from, an array of LCs whose orientations are controlled via locally applied magnetic fields. In some embodiments, the locally applied magnetic fields may be generated by driving currents through wires that intersect at micro or nanomagnetic particles or at magnetic domains, or by applying voltages to micro or nanocoils wrapped around high-permeability cores, among other things.

  • Patent number: 11681197
    Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.
