Abstract
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.
