Abstract

An outdoor display includes a net formed of intersecting cables and a number of pixel display units disposed on the net at the intersection of a pair of cables. Each pixel unit includes a number of different colored LEDs. The LEDs of the pixel units forming the display are selectively activated to form a still image or moving video images. The net display can be attached to, supported by or between existing structures.

Claims

1. A display for use outdoors comprising:

a net formed of a first set of generally parallel cables and a second set of cables, the cables in the second set intersecting cables in the first set; and

a plurality of spaced pixel units mounted on the net, each pixel unit having a plurality of light emitting diodes in a plurality of colors mounted on a support.

2. A display as recited in claim 1 wherein each pixel unit includes at least one red light emitting diode, one green light emitting diode and one blue light emitting diode.

3. A display as recited in claim 1 wherein the net includes a power line and a control line, each pixel unit being coupled to a power line and a control line.

4. A display as recited in claim 1 wherein the cables in the second set are generally parallel to each other.

5. A display as recited in claim 4 wherein the cables of the second set are generally perpendicular to the cables of the first set.

6. A display as recited in claim 1 wherein the cables in the second set include a first group of generally parallel cables and a second group of generally parallel cables wherein the first group of cables intersects the second group of cables and the first and second group of cables intersect the first set of cables.

7. A display as recited in claim 1 wherein adjacent pixel units are spaced apart on the net by 1.5 to 12 inches.

8. A display as recited in claim 1 wherein the pixel units are uniformly spaced on the net.

9. A display for use outdoors comprising:

a net formed of a first set of generally parallel cables and a second set of cables, the cables in the second set intersecting cables in the first set; and

a plurality of spaced pixel units mounted on the net, each pixel unit having a plurality of lights in a plurality of colors mounted on a support, each pixel unit being mounted on the net at an intersection of a cable from the first set and a cable from the second set.

10. A display as recited in claim 9 wherein each of the lights is a light emitting diode.
