Claim:
1. An autostereoscopic display for simultaneously displaying more than two different images, comprising a pixel matrix having a multitude of pixels which are arranged in different rows, wherein a plurality of more than two disjoint subsets of pixels are defined on the pixel matrix so that each of the subsets forms a band of parallel strips which include a non-zero angle with the rows, wherein the strips of the different subsets alternate cyclically in the row direction; an optical element which is arranged in front of or behind the pixel matrix, which has a grid-like structure orientated parallel to the strips and imposes, for each of the pixels, a defined propagation direction on light emanating or transmitted from the respective pixel such that, at a nominal distance from the display predefined by a geometry of the display, a number, corresponding to the named plurality, of viewing zones, which are laterally offset relative to one another, is defined so that each of the viewing zones is associated with exactly one of the subsets and such that the light emanating or transmitted from each of the subsets of pixels is directed in the viewing zone associated with this subset; and a control unit for controlling the pixel matrix in dependence on image data which define a 3D image, wherein the control unit is configured to carry out the respective following steps for controlling the pixel matrix for an autostereoscopic viewing of the 3D image from a viewing distance differing from the nominal distance in front of the display for each of the strips of pixels:
