Abstract
A display method and system are described for displaying a stereo image comprising a first image and a second image. A light valve array comprising an array of light valve elements is driven according to an image and a light source is provided for generating a shaped light beam which can illuminate a portion of the light valve array. A scanning device is provided which is arranged to scan the shaped light beam across the light valve array. Light valve elements of the same light valve array are caused to sequentially adopt a state representative of the first image of the stereoscopic image and a state representative of the second image, and to cause the light valve elements to adopt a new state representative of one of the first and second images in advance of the scanning by the shaped light beam and to change to a new state representative of the other of the first and second images during a period between successive scans of the shaped light beam.
