Abstract
A display arrangement in which a viewer experiences the effect of depth in conjunction with a two-dimensional display. Varying depth effects are applied to the two-dimensional display by moving rapidly transparent elements of varying thickness transversely to the direction of vision of the viewer. The transparent elements are held and mounted in a rotating disc in the form of segments, and the disc with the transparent segments is rotated rapidly in front of the two-dimensional display.
