1. Projection display comprising an imager that is implemented to generate individual images in a distribution of sub-areas of an imaging plane of the imager; a multi-channel optics comprising channels, which is configured to map one allocated sub-area of the imager each per channel, such that the mappings of the individual images are combined to an overall image in a projection area, wherein the channels of the multi-channel optics are arranged in an elongated array oriented at least approximately like at least one elongated image feature of the overall image, so that a two-dimensional anisotropic out-of-focus behavior of each projected image point is acquired.
