    Abstract: A projection arrangement includes a laminated pane including an outer and inner panes connected to one another via a thermoplastic intermediate layer, a reflective layer arranged between the outer and inner panes 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 the radiation of which 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 at least one optically high-refractive layer having a refractive index of greater than or equal to 1.9 and at least one optically low-refractive layer having a refractive index of less than or equal to 1.6.

    Abstract: A projection arrangement for a head-up display (HUD), includes a composite pane, including an outer pane and an inner pane, which are connected to one another via a thermoplastic intermediate layer and having an HUD region, and an HUD projector, which is directed toward the HUD region. The radiation of the projector is at least partially p-polarised, and the composite pane is provided with a reflective layer which is suitable for reflecting p-polarised radiation. The reflective layer includes precisely one electrically conductive layer based on silver, which layer is arranged in a planar manner between a first layer module and a second layer module, the first layer module is the layer module of the reflective layer closest to the HUD projector, the first layer module and the second layer module include dielectric layers or layer sequences, and the first layer module contains a layer based on a transparent conductive oxide.

    Abstract: A laminated pane includes an outer and an inner pane each having an outer-side surface and an interior-side surface and a thermoplastic intermediate layer. The interior-side surface of the outer pane and the outer-side surface of the inner pane are connected to one another via the thermoplastic intermediate layer, a reflective layer is arranged in at least a first sub-region of the laminated pane on the interior-side surface of the inner pane directly adjacent to the surroundings, which reflective layer is configured to reflect p-polarized light of a light source, an opaque cover layer is arranged at least in a second sub-region of the laminated pane. Starting from the interior-side surface, the reflective layer includes an optically high refractive index layer with a refractive index of greater than or equal to 1.7 and an optically low refractive index layer with a refractive index of less than or equal to 1.6.
