Abstract

A three dimensional display comprises (a) a plurality of switchable screens (2a-e) arranged one behind the other, each screen being independently switchable between a strongly scattering and substantially transparent state; (b) projection means (3) for projecting a sequence of images, each image in the sequence corresponding to one of the switchable screens and forming part of an overall three-dimensional image; and (c) synchronized switching means (4) for switching each switchable screen synchronously with the projection of the sequence of images by the projection means, such that a particular switchable screen is in its strongly scattering state when image corresponding thereto is being projected and is in its substantially transparent state at least when the image corresponding to another screen is being projected and the particular screen is positioned between that another screen and either the projector or the viewer.
