Abstract
Systems and methods for improving the brightness of a transparent display are disclosed herein. One embodiment collects ambient light using an array of metasurface lenses disposed on an external surface of a vehicle; collects internal light from the vehicle's headlights; filters the ambient light and the internal light to produce filtered ambient light and filtered internal light; generates primary-source light using a light-emitting-diode (LED) light source; and injects, 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 in a color-synchronized manner. The filtered ambient light and the filtered internal light improve the brightness of the transparent edge-lit liquid crystal waveguide display.
