Apple invents an advanced External Display System for Autonomous Passenger Vehicles that communicates with the public

Patent Title: System with One-Way Filter over Light-Emitting ElementsApple begins by noting that a vehicle may have an exterior display. The exterior display may display symbols that correspond to intended actions for the vehicle or symbols that correspond to instructions for nearby pedestrians. The microlens array may focus display light through the holes in the mask, allowing the display light to be visible to a viewer. The masking layer in the exterior display may be formed by a black material (giving the display a black appearance in its off state). The exterior display may have a planar output surface (with corresponding planar display layers) or a non-planar output surface (with corresponding non-planar display layers).
