Abstract

A liquid crystal display system having a plurality of liquid crystal display (LCD) units arranged in a tile configuration. The units simultaneously display different data as determined by the channelization. Each channel controls the operation of one or more units and provides redundant data to be displayed if needed.

Claims

1. A liquid crystal display system comprising:

four autonomous liquid crystal display units arranged adjacent to each other;

a housing comprising a structural support system, said housing substantially surrounding said units; and

a channelization system in communication with said units, said channelization system comprising;

a first channel processor coupled to first and second data sources and to first and second liquid crystal display units; and

a second channel processor coupled to the first and second data sources and to third and fourth liquid crystal display units,

wherein each of the first and second channel processors is operable to control the data from both of the data sources to present on the respectively coupled displays.

2. The system of claim 1, wherein said structural support system comprises a frame secured to a cavity and enclosing said units.

3. The system of claim 2, wherein said structural support system further comprises a carrier having said units disposed therein.

4. The system of claim 2, wherein said structural support system further comprises a screen divider located between said units.

5. The system of claim 1, wherein said display units display data from the same data source.

6. The system of claim 1, wherein said arranged display units comprise top display units and bottom display units.

7. The system of claim 6, wherein the top display units include the first and second display units.

8. The system of claim 6, wherein the bottom display units include the first and second display units.

9. The system of claim 6, wherein the top display units include the first display unit and the bottom display unit includes the second display unit.

10. The system of claim 6, wherein the top display units include the second display unit and the bottom display unit includes the first display unit.
