Abstract
A display for displaying an image comprises a condenser lens array having a plurality of condenser lenses; a projection lens array having a plurality of projection lenses; a plurality of optical channels which each comprise at least one condenser lens and one projection lens and are configured for projecting the image to be displayed by means of the display; and a plurality of collecting lenses arranged between optical paths of adjacent condenser lenses. A respective collecting lens is configured for collecting incident light and steering it to regions outside the projection lenses.
