Abstract: A projection arrangement includes a composite pane including transparent outer and inner panes, a thermoplastic intermediate layer, and a reflection layer, the outer pane having an outer side facing away from the thermoplastic intermediate layer and an inner side facing the thermoplastic intermediate layer and the inner pane has an outer side facing the thermoplastic intermediate layer and an inner side facing away from the thermoplastic intermediate layer, the reflection layer being arranged between the outer and inner panes and reflecting p-polarized light, the reflection layer being opaque or arranged spatially in front of an opaque background when viewed through the composite pane, and an image display device directed at the reflection layer and irradiates it with p-polarized light through the inner pane, wherein the reflection layer reflects the p-polarized light.

Abstract: A composite pane includes an outer pane having outer and inner surfaces, a first thermoplastic intermediate layer, a hologram element including a first set of holograms produced in one or more layers of a holographic material, wherein the first set of holograms includes a blue hologram that is activatable by blue light having a wavelength in a first range and is not responsive to light of other wavelengths, a green hologram that is activatable by green light having a wavelength in a second range and is not responsive to light of other wavelengths, and a red hologram that is activatable by red light having a wavelength in a third range and is not responsive to light of other wavelengths, an inner pane, and a color-selective optical filter for selective absorption of light.
