Abstract:
Systems, devices, and methods that implement waveguides in curved transparent combiners that are well-suited for use in wearable heads-up displays (WHUDs) are described. Curved transparent combiners employ an optical lens or optical lens blank with a waveguide or light guide embedded therein and with low refractive index materials interposed between one or more major surfaces of the waveguide and the optical lens or blank to facilitate total internal reflection while the waveguide is embedded in the lens. The curved transparent combiners may optionally include in-couplers and/or out-couplers to provide transparent combiners that substantially match a shape, size, and geometry of conventional eyeglass lenses and can, in some implementations, embody prescription curvatures to serve as prescription eyeglass lenses. The waveguides and in-/out-couplers are planar or curved depending on the implementation. WHUDs that employ such curved transparent combiners are also described.

Claim (Index 1):
A wearable heads-up display (WHUD), comprising:\n a support structure that in use is worn on a head of a user; a display light source to provide display light; and a transparent combiner carried by the support structure and positioned in a field of view of an eye of the user when the support structure is worn on the head of the user, the transparent combiner comprising:\n a lens having a first major surface and a second major surface, the second major surface of the lens opposed from the first major surface of the lens across a thickness of the lens, at least one of the first or the second major surfaces of the lens having a curvature that imparts at least one of a positive optical power or a negative optical power; \n a planar waveguide having a first major surface and at least a second major surface, the second major surface of the planar waveguide opposed from the first major surface the planar waveguide across a thickness of the planar waveguide, the planar waveguide; and \n a first layer of a low reflective index material located between at least a portion of the first major surface of the lens and at least a portion of the first major surface of the planar waveguide.
