    Abstract: A projection assembly for a head-up display (HUD), includes a composite pane, including an outer pane and an inner pane that are joined to one another via a thermoplastic intermediate layer, the composite pane having an HUD region; an HUD reflection layer suitable for reflecting p-polarized radiation, on the surface of the outer pane or of the inner pane facing the intermediate layer or within the intermediate layer; an HUD projector that is directed at the HUD region and that emits p-polarized radiation; and a high-refractive-index coating having a refractive index of at least 1.7 on the surface of the inner pane facing away from the intermediate layer. The high-refractive-index coating is a sol-gel coating.

    Abstract: A projection assembly for a head-up display (HUD), includes a composite pane with an electrically conductive coating, and a projector. The radiation of the projector is predominantly p-polarized. The electrically conductive coating has a first surface region within a HUD region and a second surface region outside the HUD region. The electrically conductive coating has at least one sub-region within the first surface region. The electrically conductive coating in the first surface section within the HUD region can be obtained from the electrically conductive coating in the second surface section using a subtractive method.

    Abstract: A projection arrangement includes a laminated pane that includes an inner and outer panes are connected to one another via a thermoplastic intermediate layer, a reflective layer which is arranged between the outer pane and the inner pane in at least one display region of the laminated pane, and a reflection-increasing coating which is arranged at least within the display region on an interior-side surface of the inner pane facing away from the thermoplastic intermediate layer, and a projector of which the radiation is predominantly p-polarized and which is directed toward the display region and wherein the interior-side surface of the inner pane is the face of the laminated pane closest to the projector. The reflection-increasing coating includes an optically high-refractive layer having a refractive index of greater than or equal to 1.9 and at an optically low-refractive layer having a refractive index of less than or equal to 1.6.

    Abstract: A projection assembly for a head-up display (HUD), includes a windshield with an HUD region, inner and outer panes joined via a thermoplastic intermediate layer, and a projector directed at the HUD region having a radiation predominantly p-polarized. The windshield has a reflection coating for reflecting p-polarized radiation. The reflection coating has exactly one electrically conductive layer based on silver. A lower dielectric layer or layer sequence with a refractive index of at least 1.9 is arranged below the electrically conductive layer. An upper dielectric layer or layer sequence with a refractive index of 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 between 2.10 and 3.20. The reflection coating includes no dielectric layers with a refractive index less than 1.9.

    Abstract: A projection arrangement for a head-up display (HUD), includes a composite pane including an outer and inner panes joined to one another via a thermoplastic intermediate layer and has an HUD region; and an HUD projector directed at the HUD region. The radiation of the projector is at least partially p-polarised, and the composite pane is provided with a reflection coating suitable for reflecting p-polarised radiation. The reflection coating includes n electrically conductive layers based on silver and (n+1) layer modules, wherein the layer modules and the electrically conductive layers are arranged alternatingly such that each electrically conductive layer is arranged between two layer modules, where n is a natural number greater than or equal to 1. At least one of the layer modules is formed as a layer based on a transparent conductive oxide, and the remaining layer modules, if present, are formed as dielectric layers or layer sequences.
