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.

A composite pane includes an outer pane, an inner pane, and a thermoplastic intermediate layer. The composite pane has, between the outer and inner panes, a solar protection coating that substantially reflects or absorbs rays outside the visible spectrum of solar radiation. The solar protection coating includes starting from the outer pane, a layer sequence of first dielectric module (M), first silver layer (Ag), second dielectric module (M), second silver layer (Ag), third dielectric module (M), third dielectric module (M), third silver layer (Ag), fourth dielectric module (M), wherein the silver layers (Ag, Ag, Ag) have a layer thickness relative to one another of Ag/Ag>1 and Ag/Ag>1, and the dielectric modules (M, M, M, M) have a relative layer thickness of M/M>1, M/M>1, and M/M>1.

A transparent substrate including an antireflection coating, made from a stack of thin layers of dielectric material having alternately high and low refractive indices. This stack includes a high-index first layer having a refractive index n, of between 1.8 and 2.2 and a geometrical thickness eof between 5 and 50 nm, a low-index second layer having a refractive index nof between 1.35 and 1.65 and a geometrical thickness eof between 5 and 50 nm, a high-index third layer having a refractive index nof between 1.8 and 2.2 and a geometrical thickness eof between 70 and 120 nm, and a low-index fourth layer having a refractive index nof between 1.35 and 1:65 and a geometrical thickness eof at least 80 nm.

Transparent substrate comprising an antiglare coating

The subject of the invention is a flexible or rigid, transparent substrate provided with a stack of thin layers, which includes at least one functional layer predominantly based on silver Ag placed between two coatings of dielectric material, at least one of the coatings comprising a layer predominantly based on aluminum nitride AlN. The functional layer or at least one of the functional layers is modified by incorporating at least one minor metal M other than Ag and/or the said AlN-based layer, or at least one of them, is modified by incorporating at least one metal M&prime; in a minor amount compared with the aluminum.

Transparent substrate provided with a heat-reflective multilayer stack

A stack of layers reflecting heat radiation for transparent substrates comprises at least one silver functional layer and, on both faces of the latter, antireflection layers formed by one or more metal compounds. The antireflection layer under the silver layer comprises an upper partial layer of zinc oxide contiguous to the silver layer, and an additional partial layer, under the zinc oxide layer, which is formed by aluminum nitride and is under internal tensile stresses. With the aid of the AlN layer under tensile stresses, it is possible to compensate the internal compressive stresses existing in the ZnO layer.
