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.

Composite pane for a holographic head-up display

A laminated pane includes first and second panes, a layer stack arranged therebetween including a first thermoplastic intermediate layer, a separating layer, a photopolymer layer with at least one holographic element, a carrier layer, and a second thermoplastic intermediate layer, wherein the photopolymer layer has a thickness of 5 μm to 50 μm, the carrier layer contains polyethylene terephthalate (PET), polyethylene (PE), polymethyl methacrylate (PMMA), polycarbonate (PC), polyamide (PA), polyvinyl chloride (PVC), and/or cellulose triacetate (TAC) and has a thickness of 20 μm to 100 μm, wherein the carrier layer is arranged directly adjacent the photopolymer layer, and the separating layer contains polyethylene (PE), polyvinyl chloride (PVC), and/or polymethyl methacrylate (PMMA) and has a thickness of 10 μm to 300 μm.

Laminated pane with a holographic element and method for producing the same

A composite pane, in particular for a projection assembly, includes an outer pane, an inner pane, and a thermoplastic intermediate layer arranged between the outer and the inner pane, wherein the outer and the inner pane have in each case an outer face and an inner face, and the inner face of the outer pane and the outer face of the inner pane face one another, a first masking strip, which is arranged regionally on one of the outer faces or the inner faces of the inner or the outer pane, an electrically conductive coating, and a reflection layer, which is suitable for reflecting light, wherein the reflection layer is arranged spatially in front of the first masking strip when viewed from the inner pane toward the outer pane, wherein the first masking strip overlaps the reflection layer at least in one region.

Heatable composite pane for a projection assembly

A laminated pane, includes, in this order, an outer pane, an intermediate layer, a functional element with electrically controllable optical properties that is selected from among a PDLC functional element, a PNLC functional element, or an SPD functional element, an intermediate layer, a holographic display element, an intermediate layer, and an inner pane.
