Abstract:
As car manufacturers have worked to improve the fuel efficiency of their vehicles, one of the areas where they have been able to make major improvements has been aerodynamics. As most of the drag is the result of the frontal area of the vehicle, the installation angle of the windshield has been getting smaller and smaller to facilitate the smooth displacement of air. One of the drawbacks of this approach is that the light reflected back to the driver by the windshield increases as the installation angle decreases and the incidence angle increases. At high incidence angles, the intensity of the reflection may become objectionable. The invention reduces reflection at high incident angles by means of an anti-reflective layer and a polarization layer.
