Abstract: The electronic sun shield is an electronically operated grid that enables the operators of motor vehicles and other vehicles (such as airplanes) to control the shading of their windshields. It employs electrochromic technology to electronically darken section or sections of the windshield in order to minimize the effects of glare from the sun, reflective objects, or the lights of other vehicles, as driving conditions dictate. In addition, all sections of the windshield can be darkened at once when the vehicle is parked, or at other times, to shield the interior from the sun.
