Abstract

An electronic display comprises a plurality of independently operable segments. Each of the plurality of independently operable segments comprises a plurality of picture elements.

Claims

1. An electronic display, comprising:

a plurality of independently operable segments located in said electronic display, wherein said plurality of independently operable segments comprises a first segment and a second segment, each of said plurality of independently operable segments comprising a plurality of picture elements, wherein said second segment has a rectangular shape, and wherein said first segment has a rectangular shape with a notch, and wherein said second segment is disposed in said notch in said first segment so that said first segment and said second segment together have a rectangular shape.

2. The electronic display of claim 1, wherein each of said plurality of independently operable segments comprises at least one boundary edge, and wherein at least one of said at least one boundary edges on each of said plurality of independently operable segments is at least partially contiguous with at least one of said at least one boundary edges on another of said plurality of independently operable segments.

3. The electronic display of claim 1, wherein said first segment is larger than said second segment.

4. The electronic display of claim 1, wherein said notch in said first segment is located along an edge of said first segment so that said first segment is U-shaped.

5. The electronic display of claim 1, wherein said plurality of independently operable segments comprise liquid crystal display elements.

6. The electronic display of claim 5, further comprising a plurality of independently operable backlights, wherein each of said independently operable backlights is located behind a different one of said plurality of independently operable segments.

7. The electronic display of claim 6, wherein said plurality of independently operable backlights comprise at least one light emitting diode.

8. The electronic display of claim 6, wherein said plurality of independently operable backlights comprise at least one fluorescent lamp.

9. The electronic display of claim 1, wherein said plurality of independently operable segments comprise plasma discharge display elements.

10. The electronic display of claim 1, wherein said plurality of picture elements comprise switchable dots, each of said switchable dots comprising a first state in which said switchable dot is visible and a second state in which said switchable dot is not visible.

11. The electronic display of claim 1, wherein said plurality of picture elements comprise switchable symbols, each of said switchable symbols comprising a first state in which said switchable symbol is visible and a second state in which said switchable symbol is not visible.

12. The electronic display of claim 1, further comprising a touch sensitive screen located over at least one of said plurality of independently operable segments.

13. An electronic display, comprising:

a plurality of independently operable segments located in said electronic display, each of said plurality of independently operable segments comprising a plurality of picture elements; and

passive artwork located over at least one of said plurality of independently operable segments, wherein said passive artwork is substantially visible when said least one of said plurality of independently operable segments under said passive artwork is off, and wherein said passive artwork is substantially transparent when said least one of said plurality of independently operable segments under said passive artwork is on.

14. The electronic display of claim 13, wherein said passive artwork comprises a film that is substantially reflective when not backlit and substantially transparent when backlit.

15. The electronic display of claim 13, further comprising a plurality of independently operable backlights, wherein each of said independently operable backlights is located behind a different one of said plurality of independently operable segments, and wherein said passive artwork is substantially visible when said plurality of independently operable backlights behind said passive artwork is off, and wherein said passive artwork is substantially transparent when said plurality of independently operable backlights behind said passive artwork is on.
