Abstract: An eyewear device includes a support frame comprising a first frame component and a second frame component, the first frame component housing an electrical component, and an optical element mechanically coupled to the first frame component at a first side and to the second frame component at an opposing second side. The eyewear device further includes a conductive trace disposed at a surface of the optical element, the conductive trace extending across the optical element between the first side and the second side to provide a conductive pathway between the first frame component and the second frame component. A method of operating the eyewear device includes transmitting an electrical signal between the first frame component and the second frame component via the conductive trace. The first frame component can include a temple, and the second frame component can include a bridge or another temple.

Abstract: A wearable heads-up display (WHUD) reduces the prevalence of visual artifacts by employing a projector with a combiner including a plurality of combiner elements such as dichroic prisms. The projector is configured with one or more features that 1) reduce the amount of stray light generated at the combiner 2) change the path of the stray light so that the stray light is unable to exit the projector and thus is unable to create visual artifacts, or any combination thereof. By reducing the stray light that is generated and by changing the path of the stray light as described herein, the likelihood that a user will see a visual artifact is reduced, thus improving the user experience with the WHUD system.

Abstract: A light engine includes a housing, a lens barrel disposed at a first surface of the housing opposite a second surface of the housing, a dichroic combiner, and first, second, and third microLED panel assemblies, each having a microLED panel coupled to a connector interface via a flex cable. The first microLED panel assembly is disposed at a third surface of the housing and arranged such that the flex cable extends first toward the barrel assembly and then turns back toward the second surface. The second microLED panel assembly is disposed at a fourth surface of the housing and arranged such that the flex cable extends first toward the barrel assembly and then turns back toward the second surface. The third microLED panel assembly is disposed at the second surface of the housing and arranged such that the flex cable extends toward either the third surface or the fourth surface.

Abstract: A light engine includes multiple laser diodes, each configured to emit laser light, and a light source unit having multiple channels, each of the channels is associated with one of the laser diodes and configured to transmit the laser light emitted from the corresponding laser diode. The channels may be, for example, fiber optic strands or optical pathways within a channeled lightguide. The light engine further includes a ferrule coupled to the light source unit and configured to receive the laser light from the light source unit and to output a collimated beam of laser light comprising each wavelength of laser light emitted by the laser diodes.

Abstract: A rotational lens assembly reduces the size of a gap between a lens and a frame of an optical light engine projector assembly. The lens includes a thread structure arranged around the outside edge of the lens. The thread structure allows the lens to align and lock within the optical assembly via at least a partial rotation of the lens. In addition, the rotation of the lens during assembly results in a relatively small gap between the lens and the frame. The smaller gap, in turn allows the other components of the optical assembly to be manufactured with lower tolerances for variation, improving the overall performance of the optical assembly.

Abstract: A display system includes one or more low-power laser diodes, each producing an emission. The emissions are directed to an optical element that affects the direction or divergence of the emissions. The optical element redirects the emissions toward a steering element such as a MEMS-actuated mirror, or a combination of such mirrors. The steering element directs the emissions toward the incoupler of a waveguide acting as an optical combiner. The emissions propagate through the waveguide and are extracted by an outcoupler in the direction of an observer. By scanning the direction of the beam-steering element along one or several directions, an image may be formed.

Abstract: A micro-projection system for use in small electronic devices can benefit from an optical assembly equipped with light-absorbing apertures. The light-absorbing apertures can aid in reducing or eliminating stray light and associated ghost images from appearing on the display of the projection system. Modular units that include laminated stacks of such apertures, along with spacers, can be inserted into air gaps within the optical assembly. Such stacked units can be made cost effective to manufacture in high volume.
