  • Publication number: 20240248315
    Abstract: An eyewear display system incorporates a substantially transparent battery into a lens portion of the eyewear display system to serve as a waveguide substrate. The substantially transparent battery waveguide receives display light from a micro-display and transmits the display light from a proximal end of the waveguide to a distal end of the waveguide while also supplying power to the micro-display. Either a transflective mirror or a diffraction structure is disposed on the surface of the substantially transparent battery to couple light into and out of the substantially transparent battery (i.e., to serve as the incoupler and outcoupler).
