Integrated frames in wearable display devices

Designs of integrated frames for wearable display devices are described. An exemplary wearable device includes a pair of integrated lenses, a lens frame accommodate the integrated lenses and two temples coupled respectively to two opposite ends of the lens frame. The integrated lens includes a transparent optical waveguide. Each of the temples includes a conduit to accommodate a cable received at one end thereof and an enclosure on an inner side thereof, wherein the enclosure includes electronic parts powered by wires in the cable and optical parts receiving optical signals from at least two optical fibers in the cable. Depending on the implementation, the temples and/or the lens frame glows when one of the optical fibers is coupled to a light source being turned on.
