Abstract: A thermoplastic film for a laminated-glass pane, having a non-linear continuous wedge insert in both a vertical and horizontal direction in some sections, is described. In the vertical direction, the laminated-glass pane is, from the perspective of an observer, further at a lower end than at an upper end. In a laminated-glass pane equipped with the thermoplastic film, the thermoplastic film is located between two glass layers. The thermoplastic film has at least a first section having a wedge angle profile that is continuous and non-linear in the vertical and horizontal direction, such that ghost images from a head-up display are minimized in the region of the first section. The thermoplastic film also minimizes double images in transmission in the first section and in further sections.

Abstract: A head-up display (HUD), includes an imaging unit, an optical element, which is suitable for deflecting the radiation of the imaging unit in the direction of a windshield and thereby irradiating an HUD region of the windshield in order to generate a virtual image, a positioning device, which is suitable for fixing the windshield in a defined arrangement relative to the optical element, and a camera unit, which is suitable for capturing the virtual image through the windshield from different eye positions, wherein the optical element is configured such that the entire virtual image lies within the depth of field range of the camera unit.

Abstract: A vehicle composite pane having an outer pane made of glass and an inner pane made of glass that are bonded to one another via a polymeric intermediate layer is presented. According to one aspect, the intermediate layer includes a first wedge inlay and a second wedge inlay that are made of different materials, each of the inlays being wedge-shaped and having a wedge face. According to another aspect, the wedge faces are positioned one atop the other so that, in the direction from a lower edge to an upper edge of the composite pane, the thickness of the first wedge inlay increases and the thickness of the second wedge inlay decreases. According to a further aspect, at least one of the wedge inlays has a refractive index that differs from the refractive index of the outer pane and of the inner pane.

Abstract: A projection arrangement for a head-up display (HUD) is presented. The arrangement has a vehicle windshield that includes an outer pane and an inner pane bonded to one another via a thermoplastic intermediate layer. The vehicle windshield has an upper edge, a lower edge, and an HUD region. The thickness of the thermoplastic intermediate layer in the vertical course between the upper edge and the lower edge varies, at least in the HUD region, according to a wedge angle. The arrangement also has a projector that is aimed at the HUD region to generate a virtual image at a projection distance of at least 5 m. According to one aspect, a vertical radius of curvature in the HUD region is at least 6 m and a maximum value of the wedge angle is less than or equal to 0.3 mrad.
