Visual Field Display Device for a Motor Vehicle

A method for operating a visual field display apparatus having an electrically controllable area-forming pixel arrangement for generating a projection light beam with a display content;

• a reflection-suppressing deflection arrangement that is arranged on the area-forming pixel arrangement and includes one or more planar reflection surfaces, extending parallel to one another along the area-forming pixel arrangement at a predetermined acute angle thereto, for projecting the generated projection light beam onto a partially transparent reflective projection screen, as a result of which a virtual display image that is superposed into a visual field of a user is generated behind the projection screen, wherein the one or more planar reflection surfaces are formed to be light-absorbing on rear sides thereof so as to suppress interfering reflections, and wherein upper edges of the plurality of mutually parallel reflection surfaces of the reflection-suppressing deflection arrangement lie, from a view of a user, substantially in a line,
• the method comprising the steps of:
• providing a current position of a user of the visual field display apparatus;
• and
• orienting the upper edges of the plurality of mutually parallel reflection surfaces of the reflection-suppressing deflection arrangement substantially in the line leading to eyes of the user depending on the provided current user position.

A method for operating a visual field display apparatus in a motor vehicle, the visual field display apparatus having an electrically controllable area-forming pixel arrangement for generating a projection light beam with a display content;

• a reflection-suppressing deflection arrangement that is arranged on the area-forming pixel arrangement and includes one or more planar reflection surfaces, extending parallel to one another along the area-forming pixel arrangement at a predetermined acute angle thereto, for projecting the generated projection light beam onto a partially transparent reflective projection screen, as a result of which a virtual display image that is superposed into a visual field of a user is generated behind the projection screen, wherein the one or more planar reflection surfaces are formed to be light-absorbing on rear sides thereof so as to suppress interfering reflections, and wherein the area-forming pixel arrangement has at least one autostereoscopic screen and/or at least one 2D screen,
• the method comprising the steps of:
• capturing a current environment behind the projection screen including an environment located ahead of the motor vehicle;
• and
• superposing contact-analog information into the visual field of a user of the visual field display apparatus via the at least one autostereoscopic screen and/or the at least one 2D screen depending on the captured environment to support the user in navigating or for visualizing a driving situation in case of highly automated or fully automated driving.
