Abstract: A projection assembly for a head-up display (HUD), includes a windshield including an outer pane and an inner pane that are joined to one another via a thermoplastic intermediate layer, having a HUD region; and a projector that is directed at the HUD region and that emits p-polarized radiation; wherein a reflection coating is arranged on the surface of the outer pane or of the inner pane facing the intermediate layer or within the intermediate layer, which reflection coating is suitable for reflecting p-polarized radiation and which has exactly one electrically conductive layer based on silver; and an emissivity-reducing coating is arranged on the surface of the inner pane facing away from the intermediate layer, which coating has an electrically conductive layer based on a transparent conductive oxide.

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 composite pane includes a laminated stacking sequence composed of an outer pane with an exterior-side surface and an interior-side surface, an inner pane with an exterior-side surface and an interior-side surface, and at least one thermoplastic intermediate layer, which joins the interior-side surface of the outer pane to the exterior-side surface of the inner pane, wherein a heatable element is applied directly on the interior-side surface of the outer pane or on the exterior-side surface of the inner pane, and a thermal-radiation-reflecting coating is applied directly on the interior-side surface of the inner pane and/or a thermal-radiation-reflecting coating is applied directly on the exterior-side surface of the outer pane.
