  • Patent number: 11914144
    Abstract: A projection arrangement for a head-up display (HUD), includes a composite pane, including an outer and an inner pane connected to one another via a thermoplastic intermediate layer, with an HUD region; an electrically conductive coating on the surface of the outer pane or of the inner pane facing or within the intermediate layer; and a projector directed toward the HUD region. The radiation of the projector is p-polarised. The composite pane has reflectance of at least 10% relative to p-polarised radiation in the spectral range from 450 nm to 650 nm. The electrically conductive coating includes at least four electrically conductive layers, which are each arranged between two dielectric layers or layer sequences. The sum of the thicknesses of all electrically conductive layers is at most 30 nm and at least one of the electrically conductive layers has a thickness of at most 5 nm.
