A stereographic liquid crystal display (LCD) and various methods of manufacturing and operating such stereographic LCD. In one embodiment, the LCD includes: (1) first and second substrates having a cell wall structure located in an interstice therebetween that defines first and second sets of independent cells in the LCD; (2) a first controllable liquid crystal (CLC) material located in the first plurality of independent cells, the first CLC material selectively exhibiting an "on" state and an "off" state and having a first polarity when in the "on" state; and (3) a second CLC material located in the second plurality of independent cells, the second CLC material selectively exhibiting an "on" state and an "off" state and having a second polarity when in the "on" state. The first and second CLC materials are selectively driveable to cause the LCD to present a stereogram to a viewer when viewed through first and second polarizing lenses having polarities corresponding to the first and second polarities of the first and second CLC materials, respectively. |

DETAILED DESCRIPTION To address the above-discussed deficiencies of the prior art, it is a primary object of the present invention to provide a stereographic liquid crystal display ("LCD") that overcomes the deficiencies of the prior art described above.
In the attainment of the above-described primary object, the present invention provides a stereographic LCD and various methods of manufacturing and operating such stereographic LCD.
In one embodiment, the LCD includes: (1) first and second substrates having a cell wall structure located in an interstice therebetween that defines first and second sets of independent cells in the LCD; (2) a first controllable liquid crystal (CLC) material located in the first plurality of independent cells, the first CLC material selectively exhibiting an "on" state and an "off" state and having a first polarity when in the "on" state; and (3) a second CLC material located in the second plurality of independent cells, the second CLC material selectively exhibiting an "on" state and an "off" state and having a second polarity when in the "on" state.
The first and second CLC materials are selectively driveable to cause the LCD to present a stereographic image to a viewer when observed through first and second polarizing lenses having polarities corresponding to the first and second polarities of the first and second CLC materials, respectively.
In one embodiment, the first and second controllable liquid crystal materials are cholesteric liquid crystals, which have the characteristic of multi-stability.
The present invention therefore provides an LCD that can produce stereographic, or "three-dimensional," images to a viewer.
When a viewer observes the stereographic image with appropriate polarizing filters (such as may be provided in the form of eyeglasses), light of one polarization is provided to one eye and light of another polarization is provided to the other eye.
Depending upon what pictorial information is provided to the LCD, the viewer may perceive the result as a three-dimensional image, significantly enhancing the utility and aesthetic appeal of the image
