  • Patent number: 11340452
    Abstract: A heads up display system of a vehicle includes a combiner screen having a first substantially transparent substrate defining a first surface and a second surface, a second substantially transparent substrate defining a third surface and a fourth surface. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic material is positioned within the cavity and a transflective layer having a multilayer polymeric film positioned on one of the first and second surfaces, and a projector for projecting light having a first polarization toward the first surface of the first substrate.
    Type: Grant
