Projektionsdisplay und Verfahren zum Anzeigen eines Gesamtbilds für Projektionsfreiformflächen oder verkippte Projektionsflächen

A projection display comprising an imaging unit is described, said imaging unit being designed to generate individual images in a distribution, such as e.g. a two-dimensional distribution, of partial regions of an imaging plane of the imaging unit, and a multi-channel optical unit, which is configured to image per channel in each case an assigned individual image or an assigned partial region of the imaging unit, to be precise such that the imaging of the individual images in a projection surface is at least partly superimposed to form a total image, wherein the projection surface is a non-planar freeform surface, such as e.g. a curved surface, and/or is tilted relative to the imaging plane, and the imaging unit is designed in such a way that constellations of points in the partial images which are respectively superimposed by the multi-channel optical unit in a respective common point in the total image differ depending on the distance between the respective common point in the total image and the multi-channel optical unit. Alternatively, imaging unit and multi-channel optical unit are designed in such a way that a manifestation of a contribution of each channel to the total image varies locally across the total image depending on the distance between the respective common point in the total image and the multi-channel optical unit.
