Stereoscopic display

A stereoscopic display comprising:

• a display to selectively display a plurality of stereo-pairs, each of said stereo-pairs comprising right and left eye perspectives to be observed by a respective plurality of observers;
• a backlight source disposed behind said display opposite said plurality of observers, said backlight source having variable regions which direct said plurality of stereo-pairs to respective ones and not the others of said right and left eyes of said plurality of observers;
• and
• a matrix lens array to direct said plurality of stereo-pairs to respective ones and not the other of said right and left eyes of said plurality of observers, and only to respective ones of said plurality of observers, said matrix lens array being provided on a plane from which said matrix lens array focuses an optical image of said plurality of observers substantially on a screen of said display in geometrical agreement with said variable regions of said backlight source.
