Abstract

Exemplary embodiments comprise static and dynamic advertising displays where the backlight is provided by any one of the following: LED'"'"'s, organic light emitting diodes (OLED), field emitting display (FED), light emitting polymer (LEP), and organic electro-luminescence (OEL). The backlights for both the static and dynamic advertising displays may be constructed of multiple tiles of lights, such that a single tile may be replaced without having to replace the entire backlight assembly. The display may be mounted on a vertical surface, and components may be repaired or replaced without having to remove the entire display from its mounted position.

Claims

a mounting element;

an image assembly substantially parallel to and substantially aligned with said mounting element;

a plurality of lights between said image assembly and said mounting element and attached to said mounting element; and

a means for powering said lights.

2. The display from claim 1 wherein said plurality of lights are LEDs.

3. The display from claim 1 wherein:

said plurality of lights are any one of the following;

organic light emitting diodes (OLED), field emitting display (FED), light emitting polymer (LEP), and organic electro-luminescence (OEL).

4. The display from claim 2 wherein said mounting element comprises a printed circuit board (PCB) having a front and rear surface.

5. The display from claim 4 further comprising:

a light diffuser element between said plurality of lights and said image assembly.

6. The display from claim 4 wherein said PCB is a metal core PCB.

7. The display from claim 1 wherein said means for powering said lights comprises:

a power source;

a first group of lights comprising two or more lights connected in parallel;

a positive conduction line connected to said power source and to said first group of lights;

a second group of lights comprising two or more lights connected in parallel, wherein said second group of lights is connected in series to said first group of lights; and

a negative conduction line connected to said second group of lights and returning to said power source.

8. The display from claim 7 further comprising:

a third group of lights comprising two or more lights connected in parallel; and

wherein said third group of lights is connected in series to said second group of lights and to said negative conduction line returning to said power source.

9. The display from claim 8 wherein said lights are LEDs.

10. The display from claim 1 wherein said mounting element comprises a plurality of tiles.

11. The static display from claim 6 further wherein:

the rear surface of said PCB is metallic; and

further comprising a fan directing air over said metallic surface.

12. The display from claim 1 wherein the front surface of the image assembly is less than four inches from the vertical surface when the display is mounted onto a vertical surface.

13. The display from claim 2 wherein the image assembly is a scrolling image assembly.

14. A static advertising display comprising:

a printed circuit board (PCB) having front and rear surfaces;

a plurality of LEDs attached to the front surface of said PCB;

a static image assembly substantially parallel and substantially aligned with the front surface of said PCB;

a light diffusing element between said plurality of LEDs and said image assembly; and

a means for powering said LEDs.

15. The static display from claim 14 wherein said means for powering said LEDs comprises:
