Claim 1:
2. A method for displaying a first image in a first direction towards a first observer and displaying a second image in a second direction towards a second observer by means of a time multiplexed display system, said first observer observing said first image from a first viewpoint in front of said time multiplexed display system and said second observer observing said second image from a second viewpoint in front of said time multiplexed display system, said method comprising:
providing said time multiplexed display system including:
a tracking system for tracking or detecting the position of said first observer or a part of said first observer such as an eye, and for tracking or detecting the position of said second observer or a part of said second observer,
a display screen having a plurality of image pixels for displaying said first image and said second image,

said display screen configured for displaying said first image and said second image at a frame rate,
a controller for controlling the direction of light emitted from said display screen such that said first image being visible from said first viewpoint, and said second image being visible from said second viewpoint,
a first memory for storing tracking data,

said method comprising:
tracking said first observer by means of said tracking system and writing tracking data into said memory at a position of a number of don't care pixels,
displaying said first image by means of said display screen,
said controller reading said tracking data from said memory while said first image being displayed, and directing light from said display screen in a direction towards said first viewpoint, such that said first image being visible by said first observer when said first observer changing said viewpoint while said first image being displayed, and
tracking said second observer by means of said tracking system and writing tracking data into said memory at a position of a number of don't care pixels,
displaying said second image by means of said display screen,
said controller reading said tracking data from said memory while said second image being displayed, and directing light from said display screen in a direction towards said second viewpoint, such that said second image being visible by said second observer when said second observer changing said viewpoint while said second image being displayed.
