composite panel for a front pilot collimator (hud) with an electrically conductive coating and an anti-reflective coating

摘要

the present invention relates to a composite panel (10) for a front pilot collimator (hud) with an upper edge (o), a lower edge (u) and a hud region (b), comprising at least one outer panel (1) and an inner panel (2), which are joined together by means of a thermoplastic intermediate layer (3) and an electrically conductive transparent coating (20) on the surface (iii) of the inner panel (2) facing the intermediate layer (3) or inside the intermediate layer (3), where the intermediate layer (3) is formed by at least one layer (3a) of thermoplastic material, which is arranged between the electrically conductive coating (20) and the panel outer (1), where the thickness of the layer (3a) of the thermoplastic material is variable with the wedge angle (a) along its vertical course between the lower edge (u) and the upper edge (o) at least in hud region (b), and where an anti-reflective coating (30) is applied to the surface (iv) of the inner panel (2) facing away from the middle layer (3).
