Abstract
A projection display includes an imager for displaying sub-images in a two-dimensional distribution of sub-areas of the imager and a projection optics array with a two-dimensional distribution of projection optics. The projection optics array is configured to superimpose projections of the 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. Here, the projection display is implemented such that the overall image is a virtual overall image.
Claims15
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.
Method for projecting an overall image with a projection display, comprising:
- displaying sub-images with an imager in a two-dimensional distribution of sub-areas of the imager;
- superimposing projections of the sub-images to an overall image in an image plane by a projection optics array with a two-dimensional distribution of projection optics 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.
