Image display system

An image display cell, comprising:

• a top substrate;
• a bottom substrate;
• a first light modulating device;
• and
• a second light modulating device capable of spatially or angularly directing light emitting from a light source, wherein the first and second light modulating devices are interposed between the top and bottom substrates.

An image display system, comprising:

• a display device for providing right-eye images and left-eye images;
• an optical means for modulating light beams associated with the right-eye images and light beams associated with the left-eye images to form substantially collimated light beams;
• and
• a light modulating device disposed adjacent to the display device, for spatially or angularly directing the substantially collimated right-eye light beams to the right eye of a viewer and spatially or angularly directing the substantially collimated left-eye light beams to the left eye of the viewer, such that the substantially collimated right-eye and left-eye light beams form three dimensional images.

An electronically switchable light modulating cell, comprising:

• a compartment defined by a bottom substrate, two or more sidewalls, and a top substrate;
• a light shielding layer disposed on at least one of the top substrate and the bottom substrate, such that light propagating through the compartment is at most partially shielded by the light shielding layer;
• and
• a light modulating medium filled in the compartment.

A method for displaying stereoscopic images associated with an image display system comprising a display device and a light modulating device disposed adjacent to the display device, wherein the display device has a first display area and a second display area, comprising:

• controlling the light modulating device to spatially or angularly deflect light beams associated with right-eye images to the right eye of a viewer and to spatially or angularly deflect light beams associated with left-eye images to the left eye of the viewer;
• during a first period, displaying by the display device a black frame in the first display area when the display device displays the right-eye or left-eye images in the second display area;
• and
• during a second period, displaying by the display device a black frame in the second display area when the display device displays the right-eye or left-eye images in the first display area.
