A system and a method for controlled concurrent viewing of images, in their entirety, by the use of a dual viewer controllable dual display system having the added capability of individually presented resolution is disclosed. In operation, a viewer first selected image is provided by a first controllable display device and a viewer selected second image, typically different from the first, is provided by a second controllable display device. A viewer looks through the second display and sees the image presented by the first display and the image presented by the second display provided at the plane of the first display. Additionally, the displays can be interactive, in that an image or event provided on one display results in the presentation of an image or other data on the other display, all the while allowing the viewer to select from other information. Also the position of one image can be varied with respect to the other image.

Large screen display with projected overlay and method of using same

An autostereoscopic display includes a projection system which generates a plurality of real images that represent different spatial views of an object and further includes a plurality of contiguous field lenses. From the real images, the field lenses form a plurality of exit pupils which are separated by one interpupillary distance. An observer can 'walk around' the display and observe different stereoscopic views of the object by positioning his eyes at an adjacent pair of exit pupils.

Autostereoscopic display and method

A volumetric display system includes a display member which has a plurality of electrically-responsive optical shutters arranged in a layered relationship. The optical shutters include layers of a liquid crystal which preferably can be formed in geometric shapes which enhance the volumetric display. A projection system projects successive images onto the display member while successive ones of the optical shutters are switched into their translucent state. At any moment in time, all optical shutters except the successive one are maintained in a transparent state.

Layered display system and method for volumetric presentation

A projection system wherein two or more separate display sources, such as high brightness sources, or active matrix liquid crystal display (AMLCD) or other flat panel displays are used to write information directly onto a display screen, or onto a photoactivated reflective light valve for projection onto the display screen. Sequential imaging apparatus is used to alternately generate first and second images for display. For example, such images are coupled to the photoactivated reflective light valve and an illumination source is employed to illuminate the light valve and project a composite image onto the display screen. The flat panel displays may be transmissive, reflective, or self-emissive with the use of an optical shutter. A writing illumination source is used for non-self-emissive flat panel displays. Using high brightness display sources, the images may be directly written onto the display screen without the use of the reflective photoactivated light valve and the illumination source. In the present invention, each video frame is divided equally among the AMLCD/flat panel displays either spatially or temporally, and the flat panel displays are optomechanically multiplexed or optically shuttered by a multiplexer, thus imaging partial frames of information sequentially or completely onto the photoactivated light valve. This results in a complete frame or sequence of frames written onto the photoactivated light valve and displayed on the screen. The present invention reduces the data rate requirements on the image sources by a factor of two, four, or more. This is a significant advantage for super-definition projection systems with multi-megapixel count requirements. Blemish/defect mitigation is achieved by alternately writing to the flat panel displays using a ping-pong approach with one-to-one full resolution flat panel displays.
