PROJECTION DISPLAY AND METHOD FOR DISPLAYING AN OVERALL IMAGE FOR FREE-FORM PROJECTION SURFACES OR TILTED PROJECTION SURFACES

摘要

A projection display with an imager is described which is adapted to be used in a distribution, e.g. a two-dimensional distribution to generate individual images of sub-areas of an imaging plane of the imager, and a multi-channel optics which is configured to image an assigned individual image or an assigned sub-area of the imager per channel, in such a way that the image of the individual images is in a The projection surface is at least partially superimposed to form an overall image, the projection surface being a non-planar free-form surface, such as a curved surface and / or is tilted with respect to the imaging plane, and the imager is designed such that constellations of points in the partial images, which are superimposed by the multi-channel optics in a respective common point in the overall image, differ depending on which Distance the respective common point in the overall image possesses from the multi-channel optics. Alternatively, the imager and multi-channel optics are designed in such a way that an expression of a contribution of each channel to the overall image varies locally across the overall image depending on the distance between the respective common point in the overall image and the multi-channel optics.
