摘要： 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.

摘要： A method and a corresponding device for providing a glare shield in a vehicle is designed to select a first element from the plurality of elements of the first layer, so that the first element lies on a light trajectory between the source of glare and a first eye of the viewer, the light trajectory between the source of glare and the first eye lies within the viewing direction range of the first element, and a light trajectory between the source of glare and a second eye of the viewer lies outside of the viewing direction range of the first element.

摘要： A method operates a visual field display device, in particular for a motor vehicle, which is designed to produce a projection light beam with a display content and to project the display content onto a partially transparent reflecting projection screen, in particular a front window of the motor vehicle, such that a virtual display image which is superimposed into a field of vision of a user is generated behind it. The method determines image element edges having vertical or a vertical component in the virtual display image to be superimposed and tilts the image element edges thus determined to a respectively adapted tilt angle with respect to the vertical, such that double images of the respective image element edges in the virtual display image are offset with respect to each other in the horizontal direct for the user due to double reflections of the projection light beam on two optical boundaries of the projection screen and appear substantially sharp.

摘要： A method operates a visual field display device, particularly for a motor vehicle, which includes an autostereoscopic planar pixel array for generating a projecting light beam containing a display content, and is designed to project this onto a partially transparent, reflective projection screen, particularly a front windscreen of the motor vehicle, in such a way that a virtual display image superimposed into a field of vision of a user is generated behind the screen. The method provides at least one surroundings parameter and/or user parameter, and switches between at least two qualitatively different 3D, 2D and/or monocular operating modes of the planar pixel array, depending on the surroundings parameters and/or user parameters provided, in order to adapt the virtual display image to qualitative operational changes relating to the surroundings and/or the user of the visual field display device.

摘要： A visual field display device for a motor vehicle includes an electrically controllable, planar pixel arrangement, particularly at least one flat screen monitor, for producing a projection light beam having a display content, a reflection-suppressing deflection arrangement arranged on the planar pixel arrangement, including one or more flat reflection surfaces, extending along the planar pixel arrangement at a predetermined, acute angle thereto and parallel to one another, for projecting the generated projection light beam onto a partially transparent, reflective projection pane, particularly a windshield of the motor vehicle. As a result, a virtual display image, shown in a visual field of a user, is generated behind it. The one or the plurality of reflection surfaces are designed on the rear sides thereof in a light-absorbing manner in order to suppress interfering reflections.
