1. A display system for showing a stereoscopic image, comprising:
an image source adapted to generate left and right components of the stereoscopic image;
a screen operatively connected to the image source and adapted to display the left and right components of the stereoscopic image;
a light source adapted to selectively emit a plurality of parallel light strips;
a lenticular panel having a plurality of parallel lenses, each given lens of the lenticular panel being configured to direct light from a given light strip of the light source toward the screen in a direction determined by relative positions of the given light strip and of the given lens;
a directional diffuser positioned in a path of the light between the lenticular panel and the screen, an axial rotation of the directional diffuser in relation to the lenticular panel allowing to hide at least in part a pattern of the lenses of the lenticular panel;
a tracking system adapted to track a position of a viewer; and
a controller operatively connected to the image source, to the light source, and to the tracking system, the controller being configured to:
receive at least one of:
the position of the viewer from the tracking system, the controller being configured to further calculate positions of left and right eyes of the viewer based on the position of the viewer, and
the positions of the left and right eyes of the viewer from the tracking system,
in a first timeslot of a repeating succession of timeslots, (i) cause the image source to generate the left component of the stereoscopic image, and (ii) cause lighting of a selected first group of light strips directed by the lenticular panel through the screen and toward the left eye of the viewer for showing pixels of the left component of the stereoscopic image, selection of the first group of light strips being based on the at least one of the position of the viewer and the positions of the left and right eyes, and
in a second timeslot of the repeating succession of timeslots, (i) cause the image source to generate the right component of the stereoscopic image, and (ii) cause lighting of a selected second group of light strips directed by the lenticular panel through the screen and toward the right eye of the viewer for showing pixels of the right component of the stereoscopic image, selection of the second group of light strips being based on the at least one of the position of the viewer and the positions of the left and right eyes.
