Method for Operating a Visual Field Display Device for a Motor Vehicle

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.
