  • Patent number: 5917539
    Abstract: A stereoscopic image display system includes an image display screen for displaying images; a controller and a display driver circuit for causing left-eye images and right-eye images to be produced on the display screen in a format of image components which at any particular time define a left-eye image field interlaced with a right-eye image field; a shutter system having variable transparency shutter components positioned in front of the image display screen for defining a viewing position on the opposite side of the shutter system from the display screen. The transparency of the shutter components is controlled to attenuate the left-eye image field from view by the right eye of a viewer at the viewing position, to attenuate the right-eye image field from view by the left eye of the viewer, to enable view of the left-eye image field by the left eye of the viewer, and to enable view of the right-eye image field by the right eye of the viewer.
