  1. WINDSHIELD GLASS FOR HEADUP DISPLAY


    1. Windshield glass has a wedge-shaped inner PVC film. This film, with its varying thickness, is located between the outer and inner layers of glass.

    2. The light that strikes the glass is reflected by the inner surface of the inner glass, and also by the inner side of the outer surface of outer layer of glass. With a conventional windshield, the light reflected from these 2 surfaces diverges due to the thickness of the glass, resulting in a double image.

    3. The PVC film uses its wedge shape to eliminate the reflection angle difference between the outer glass and inner glass. As a result, the reflected light is displaced to reduce double images.

    4. Thus, the reflected light from the headup display unit is recognized by the driver as a single display image.
