Abstract:
A method for operating a field-of-vision display device for a motor vehicle, including an electrically controllable planar pixel assembly for generating a projection light beam having a display content and a reflection-suppressing deflection assembly, which is arranged on the planar pixel assembly and includes one or more flat reflection surfaces, extending along the planar pixel assembly at a predefined acute angle thereto and parallel to one another, for projecting the generated projection light beam onto a partially transparent, reflective projection pane, including a windshield of the motor vehicle, as a result of which a virtual display image shown in a field of vision of a user is generated behind the projection pane, wherein: the one or more reflection surfaces are each light-absorbing on the rear side thereof in order to suppress interfering reflection; at least one driving situation parameter is provided, in dependence on which different area segments of the planar pixel assembly are used to generate a desired display content.
