  • Patent number: 9108566
    Abstract: A vehicle headlamp system includes a headlamp assembly having a light source and a beam pattern panel. The beam pattern panel includes one or more regions capable of changing between opaque and transparent light-transmission states to selectively allow light from the light source to pass through the panel. The panel may be an LCD panel with a plurality of liquid crystal elements arranged in an array with the ability to provide a plurality of different beam patterns. The beam pattern may be determined and changed in real time based on information received at a system processor about one or more vehicle and/or road conditions. The headlamp system can direct a projected light beam into a curve in the road ahead and/or automatically change the direction of the projected beam to avoid shining light directly at oncoming drivers.
