    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 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 composite pane includes an outer pane having an exterior-side surface and an interior-side surface, an inner pane having an exterior-side surface and an interior-side surface, and a thermoplastic intermediate layer joining the interior-side surface of the outer pane to the exterior-side surface of the inner pane. The composite pane has a sun shading coating between the outer and inner panes. the sun shading coating includes, starting from the outer pane toward the inner pane, a layer sequence first dielectric module M1, first silver layer Ag1, second dielectric module M2, second silver layer Ag2, third dielectric module M3, third silver layer Ag3, fourth dielectric module M4, wherein the silver layers have, relative to one another, a geometrical layer thickness of 0.4
