Claim 13:
14. A method, comprising:
collecting ambient light using an array of Fresnel lenses disposed on an external surface of a vehicle;
collecting internal light from headlights of the vehicle;
filtering the ambient light and the internal light to produce filtered ambient light and filtered internal light, the filtered ambient light and the filtered internal light including red, green, and blue color components;
generating primary-source light using a light-emitting-diode (LED) light source that outputs, in a predetermined alternating manner, red, green, and blue light; and
injecting, into a transparent edge-lit liquid crystal waveguide display deployed in at least a portion of a window of the vehicle, the primary-source light, the filtered ambient light, and the filtered internal light, wherein the red, green, and blue color components of the filtered ambient light and the filtered internal light are time-synchronized with the red, green, and blue light, respectively, of the primary-source light and the filtered ambient light and the filtered internal light improve the brightness of the transparent edge-lit liquid crystal waveguide display.
