Abstract

A first and second display assembly are moveably mounted to a frame. At least one of the display assemblies includes a cover, an electronic display located behind the cover, and a first and second channel. A fixed plate is attached to the frame and positioned entirely within a cavity located between the display assemblies and the frame. The cavity and the first channel are part of a closed loop pathway, while the second channel is part of an open loop pathway. The closed loop is sealed when the display assemblies are in a closed position, and the fixed plate is accessible when the display assemblies are in an open position.

First claim

What is claimed is:

1. An electronic display assembly comprising:
a frame;
a first and second display assembly mounted to the frame, at least one of said first and second display assemblies comprising:
a cover;
an electronic display located behind the cover;
a first channel configured to receive circulating gas; and
a second channel configured to receive ambient air;

a cavity located between rear surfaces of the first and second display assemblies and within the frame;
a fixed plate attached to said frame and positioned entirely within the cavity, wherein said fixed plate is spaced apart from the rear surfaces of said first and second display assemblies, and wherein said fixed plate is configured to receive electronic components;
a closed loop pathway comprising said cavity and said first channel; and
an open loop pathway comprising said second channel;
wherein said first and second display assemblies are mounted to said frame in a manner which permits movement between a closed position where said closed loop pathway is sealed and an opened position where said fixed plate is accessible.

2. The electronic display assembly of claim 1 wherein:
the first channel is located between the cover and the electronic display.

3. The electronic display assembly of claim 1 wherein:
the second channel is located behind the electronic display.

4. The electronic display assembly of claim 1 wherein:
the electronic display comprises a layer of liquid crystals.

5. The electronic display assembly of claim 1 wherein:
the electronic display is directly backlit.

6. The electronic display assembly of claim 1 wherein:
the electronic display is edge lit.

7. The electronic display assembly of claim 1 wherein:
the frame is configured for mounting to a sidewalk.

8. The electronic display assembly of claim 1 wherein:
the frame is configured for mounting to the roof of a vehicle.

9. The electronic display assembly of claim 1 wherein:
at least one of the first and second display assemblies is configured to accommodate a static poster.

10. The electronic display assembly of claim 1 wherein:
at least one of the first and second display assemblies is configured to accommodate an access panel.

11. The electronic display assembly of claim 1 further comprising:
an open loop fan located along said open loop pathway and configured to move ambient air through at least a portion of said open loop pathway when operated; and
a closed loop fan located along said closed loop pathway and configured to move circulating gas through at least a portion of said closed loop pathway when operated.

12. The electronic display assembly of claim 1 wherein:
said fixed plate comprises a server rack.

13. The electronic display assembly of claim 1 further comprising:
a number of pass through devices located on the frame and configured to accommodate cabling extending from outside the cavity to a location within the cavity.

14. The electronic display assembly of claim 1 wherein:
said first and second display assemblies are moveably mounted to the frame in a manner which permits rotation of said first and second display assemblies about a first and second vertical axis, respectively.

15. The electronic display assembly of claim 1 wherein:
said first and second display assemblies are moveably mounted to the frame in a manner which permits rotation of said first and second display assemblies about a first and second horizontal axis, respectively.

16. The electronic display assembly of claim 1 wherein:
said first and second display assemblies are mounted to the frame in a back to back arrangement with one another.

17. A method for providing an electronic display assembly, said method comprising the steps of:
securing a fixed plate to a frame;
mounting a first and a second display assembly to the frame such that the fixed plate is located between rear surfaces of said first and second display assemblies, wherein at least one of said first and second display assemblies comprise:
a cover;
an electronic display located behind the cover;
a first channel configured to receive circulating gas; and
a second channel configured to receive ambient air;

moving circulating gas through a closed loop pathway comprising the first channel and a cavity located between the rear surfaces of the first and second display assemblies, an upper edge, a lower edge, and side edges of the frame;
moving ambient air through an open loop pathway comprising the second channel; and
moving at least one of said first and second display assemblies between a closed position where said closed loop pathway is sealed, and an opened position where said fixed plate is accessible, wherein said fixed plate is located entirely within said cavity.

18. The method of claim 17 further comprising the steps of:
mounting at least one electronic component to said fixed plate; and
removing said at least one electronic component from said fixed plate.

19. The method of claim 17 further comprising the steps of:
removing at least one of said first and second display assemblies; and
replacing the removed one of first and second display assemblies with a replacement display assembly.

20. An electronic display assembly comprising:
a frame having an upper edge, a lower edge, and side edges;
a first and second display assembly mounted to the frame in a back to back arrangement, each of said first and second display assemblies comprising:
a cover layer;
an electronic display located behind the cover layer;
a first channel located between a front surface of the electronic display and a rear surface of the cover layer, wherein said first channel is configured to receive circulating gas; and
a second channel located behind a rear surface of the electronic display, wherein said second channel is configured to receive ambient air;

a cavity located between a rear surface of the first display assembly, a rear surface of the second display assembly, the upper edge, the lower edge, the side edges of the frame;
a fixed plate affixed to said frame and positioned entirely within the cavity, wherein said fixed plate is spaced apart from the rear surfaces of said first and second display assemblies, and wherein said fixed plate is configured to receive electronic components for operating said electronic display assembly;
a closed loop pathway comprising said cavity and said first channel; and
an open loop pathway comprising said second channel;
wherein said first and second display assemblies are moveably mounted to said frame;
wherein said closed loop pathway is sealed when said first and second display assemblies are located in a closed position; and
wherein said fixed plate is accessible when said first and second display assemblies are located in an open position.

21. An electronic display assembly comprising:
a mounting structure;
a first and second side assembly, wherein at least one of said first and second side assemblies comprise:
a cover;
an electronic display located rearward of the cover;
a first channel configured to receive circulating gas; and
a second channel configured to receive ambient air;

an interior compartment located between rear surfaces of the first and second display assemblies and within the mounting structure;
a plate connected to said mounting structure in a fixed manner and positioned entirely within the interior compartment, wherein said plate is spaced apart from the rear surf
