    Abstract: A transparent pane comprising a transparent substrate and an electrically conductive coating on a surface of the transparent substrate is disclosed. The electrically conductive coating comprises four functional layers arranged one atop another. Each functional layer comprises a layer of optically highly refractive material with a refractive index >1.3, a first matching layer above the layer of optically highly refractive material, an electrically conductive layer above the first matching layer, and a second matching layer above the electrically conductive layer. The layer thickness of each conductive layer can be 5 nm to 25 nm and the total layer thickness of all electrically conductive layers can be 20 nm to 100 nm.

    Abstract: A projection assembly for a head-up display (HUD), includes a windshield, including outer and inner panes that are joined to one another via a thermoplastic intermediate layer and having an HUD region; and a projector aimed at the HUD region. The radiation of the projector is predominantly p-polarised, and the windshield is provided with a reflection coating that is suitable for reflecting p-polarised radiation. The reflection coating has exactly one electrically conductive layer based on silver, a lower dielectric layer or layer sequence whose refractive index is at least 1.9 is arranged beneath the electrically conductive layer, an upper dielectric layer or layer sequence whose refractive index is at least 1.9 is arranged above the electrically conductive layer, the ratio of the optical thickness of the upper dielectric layer or layer sequence to the optical thickness of the lower dielectric layer or layer sequence is at least 1.7.

    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.
