1. Projection display comprising: an imager for displaying sub-images in a two-dimensional distribution of sub-areas of the imager; a projection optics array with a two-dimensional distribution of projection optics implemented to superimpose projections of sub-images to an overall image in an image plane such that a mutual area overlap of the projections of the sub-images in the image plane in pairs results, which is between 0.1 and 0.8 for all pairs; wherein the projection display is implemented such that the overall image is a virtual overall image.
