The invention relates to a projection device for a head-up display (HUD), at least comprising: a windshield pane (10) having an HUD region (B), comprising an outer pane (1) and an inner pane (2) joined to one another by a thermoplastic intermediate layer (3); and-a projector (4) directed towards the HUD region (B) and emitting p-polarized radiation; wherein a reflective coating (20) suitable for reflecting p-polarized radiation and having exactly one conductive layer (21) based on silver is arranged on the surface (II, III) of the outer pane (1) or the inner pane (2) facing the intermediate layer (3) or in the intermediate layer (3); and arranging an emissivity reducing coating (30) with an electrically conductive layer (31) based on a transparent electrically conductive oxide on a surface (IV) of the inner pane (2) facing away from the intermediate layer (3).

    本发明涉及用于平视显示器(HUD)的投影装置,其至少包括‑具有HUD区域(B)的挡风玻璃板(10),其包括通过热塑性中间层(3)相互接合的外玻璃板(1)和内玻璃板(2);和‑指向HUD区域(B)并发射p偏振辐射的投影器(4);其中‑在外玻璃板(1)或内玻璃板(2)的面向中间层(3)的表面(II、III)上或在中间层(3)内布置适合于反射p偏振辐射并具有恰好一个基于银的导电层(21)的反射涂层(20);和‑在内玻璃板(2)的背离中间层(3)的表面(IV)上布置具有基于透明导电氧化物的导电层(31)的辐射率降低涂层(30)。
