Abstract
An arrangement for two- or three-dimensional display including an image display device consisting of a multitude of light-transmitting image rendering elements, on which bits of image information from several perspective views can be displayed, and a wavelength filter array and a controllable illuminator providing at least two modes of operations. In a first mode of operation, light emitted by a first light source arranged behind the wavelength filter array reaches the observer by passing through at least part of the light-transmitting filter elements and subsequently through a correlated part of the image rendering elements of the image display device, so that the scene or object is seen by the observer in three dimensions. In a second mode of operation, light emitted by a second light source reaches the observer by passing through the image rendering elements of the image display device but not through the filter elements of the wavelength filter array, so that the scene or object is seen by the observer at least partially in two dimensions, with uniform illumination in the second mode of operation being provided by suitable means.
