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. The image components that define the left-eye image field are periodically interchanged with the image components that define the right-eye image field, and the respective transparencies of the shutter components are interchanged when the image components are interchanged so that each eye views an image having twice the resolution as would otherwise be provided. The shutter system includes a plurality of parallel arrays of variable transmittance elements for composing the shutter components.
