Abstract

A large scale LED display has a number of display panels each having a cable and spacer support structure for a number of LED modules. Adjacent display panels are connected together by a number of seam links that snap onto one cable of one of the display panels and one cable of the adjacent display panel. The cables may include a number of seam link engagement members spaced along the length of the cable and onto which the seam links snap wherein each of the seam link engagement members locates an LED module on the support structure. The LED modules include top and bottom housing sections that snap together, wherein one of the housing sections includes a seat for an electrical connector. The seat locates the connector and a printed circuit assembly within the LED module.

Claims

1. A display, comprising:

a plurality of LED display panels, each display panel including a plurality of LED modules mounted in a plurality of rows on a support structure including a plurality of parallel cables and h-links, wherein an LED module is spaced from an adjacent LED module in a row by a h-link mounted on a pair of adjacent cables; and

a plurality of seam links, each seam link having a first end for snapping on a cable on the edge of one LED display panel and a second end for snapping on a cable on the edge of an adjacent LED display panel to connect the LED display panels together.

2. The display according to claim 1, wherein a cable on the edge of the display panel includes a plurality of link engagement members disposed along the length of the cable, each link engagement member being aligned with a row of LED modules, wherein the seam links snap onto a link engagement member.

3. The display according to claim 1, wherein the h-links in a row of LED display modules of the display panels are aligned and the seam link connecting the LED display panels together is aligned with the h-links in the row of LED display modules.

4. The display according to claim 3, wherein the number of seam links connecting two LED display panels together is less than the number of rows of LED display modules in the display panel.

5. The display according to claim 1, wherein the seam links provide approximately the same spacing between an LED module in one LED display panel and an adjacent LED module in a connected LED display panel as the spacing provided by the h-link between a pair of adjacent LED modules in one LED display panel.

6. The display according to claim 1, wherein each of the seam links has a cross bar extending between the first and second ends that snap on a cable, wherein the width of the cross bar is less than the width of the first and second ends.

7. A display, comprising:

a plurality of LED display panels, each display panel including at least one column of LED modules mounted on a pair of parallel cables; and

a plurality of seam links, each seam link having a first end for snapping on a cable of one LED display panel and having a second end for snapping on a cable of another LED display panel to connect the LED display panels together.

8. The display according to claim 7, wherein each of the seam links has a cross bar extending between the first and second ends that snap on a cable, and wherein the width of the cross bar is less than the width of the first and second ends.

9. A display, comprising:

a plurality of LED display panels, each display panel including at least one column of LED modules mounted on a pair of parallel cables, wherein at least one cable of each display panel has a plurality of link engagement members disposed along the length of the cable; and

a plurality of seam links, each seam link having a first end for snapping on a link engagement member on a cable of one LED display panel and having a second end for snapping on a link engagement member on a cable of another LED display panel.

10. The display according to claim 9, wherein each of the link engagement members is a substantially cylindrical member molded onto the cable.

11. The display according to claim 9, wherein a LED module is mounted on a cable adjacent to the link engagement member.

12. The display according to claim 9, wherein each of the link engagement members locates a mounting position for a LED module on the cable.

13. The display according to claim 9, wherein each of the seam links has a cross bar extending between the first and second ends that snap on a link engagement member, and wherein the width of the cross bar is less than the width of the first and second ends.

14. A display, comprising:

a plurality of LED display panels, each display panel including a plurality of LED modules mounted in a plurality of rows on a support structure that includes a plurality of parallel cables and h-links, wherein an LED module is spaced from an adjacent LED module in a row by a h-link, wherein the h-links in a row are aligned; and

a plurality of seam links, each seam link having a first end for snapping on cable on the edge of one LED display panel and a second end for snapping on a cable on the edge of an adjacent LED display panel to connect the LED display panels together, wherein a seam link is aligned with the h-links in a row.

15. The display according to claim 14, wherein a cable on the edge of the display panel includes a plurality of link engagement members disposed along the length of the cable, wherein each link engagement member is aligned with a row of LED modules, and wherein the seam links snap onto a link engagement member.

16. The display according to claim 15, wherein the number of seam links connecting two LED display panels together is less than the number of rows of LED modules in a LED display panel.

17. The display according to claim 15, wherein the seam links provide approximately the same spacing between an LED module in one LED display panel and an adjacent LED module in a connected LED display panel as the spacing provided by the h-link between a pair of adjacent LED modules in one display panel.

18. The display according to claim 15, wherein each of the seam links has a cross bar extending between the first and second ends that snap on a cable, and wherein the width of the cross bar is less than the width of the first and second ends.

19. The display according to claim 14, wherein the LED module or the adjacent LED module is one of a slave LED module and a master slave LED module.

20. The display according to claim 19, wherein the master LED module is configured differently from the slave LED, module, and wherein each master LED module and the slave LED module has respective LEDs.
