Abstract

A field serviceable assembly includes a frame with a first and second gasket located along the front and rear perimeters thereof and a first and second electronic display assembly hingedly mounted thereto in a back to back arrangement. A gap is located between a transparent layer and an electronic display in each electronic display assembly. A cavity is defined by the space between the first and second electronic display assemblies and has a plate for receiving a plurality of electronic components. The cavity and the gaps form a substantially sealed closed loop when the first and second electronic display assemblies are placed in the closed position.

First claim

What is claimed is:

1. A field serviceable assembly for displaying images comprising:
a frame having a front perimeter and a rear perimeter;
a first and second gasket located along the front perimeter and the rear perimeter, respectively, of said frame;
a first and second electronic display assembly mounted to the frame in a back to back arrangement, each of said first and second electronic display assemblies comprising:
a transparent layer;
an electronic display;
a hinging device configured to permit the electronic display assembly to rotate between an opened and a closed position; and
a gap defined by the space between the transparent layer and the electronic display, wherein the gap is configured to receive circulating gas; and
a corrugated layer;

a common cavity located in the space between the first and second electronic display assemblies and the frame, wherein said cavity is configured to receive circulating gas from both the first and second electronic display assemblies;
a plate positioned within the cavity between and substantially parallel to the rear surfaces of the electronic display assemblies, wherein said plate is configured to receive a plurality of electronic components;
a closed loop for circulating gas comprising said common cavity and said gap of said first and second electronic display assembly, wherein the closed loop is substantially sealed when the first and second electronic display assemblies are placed in the closed position; and
an ambient air pathway passing through the corrugated layer of each of the first and second electronic display assemblies.

2. The field serviceable assembly of claim 1 further comprising:
a number of pass through devices configured to permit cabling to pass into the cavity.

3. The field serviceable assembly of claim 2 wherein:
said cabling comprises power lines and communication lines.

4. The field serviceable assembly of claim 1 wherein:
said plate comprises a server rack.

5. The field serviceable assembly of claim 1 further comprising:
a first and second aid device configured to assist in moving the first and second display assemblies, respectively, between the open and the closed positions.

6. The field serviceable assembly of claim 1 wherein:
said aid devices comprise gas springs.

7. The field serviceable assembly of claim 1 wherein:
the hinging device comprises:
a pin;
a first hinge plate mounted to the frame;
a second hinge plate mounted to the respective display assembly; and
apertures in the first hinge plate and second hinge plate sized and located to permit the pin to pass therethrough.

8. The field serviceable assembly of claim 7 wherein:
the first and second electronic display assemblies may be removed from the frame by removing the respective pins.

9. The field serviceable assembly of claim 1 wherein:
said corrugated layer of said first and second electronic display assemblies is located behind the rear surface of the backlight of the respective electronic display.

10. A field serviceable assembly for displaying images comprising:
a frame having inner and outer surfaces;
an access panel mounted to the frame in a hinged fashion;
an electronic display assembly mounted to the frame in a hinged fashion such that the electronic display assembly may be moved between an opened position and a closed position, wherein the electronic display assembly comprises:
a transparent layer;
an electronic display positioned behind and substantially parallel to said transparent layer;
a backlight positioned behind and substantially parallel said electronic display;
a first gap defined by the space between the transparent layer and the electronic display; and
a second gap positioned along the rear surface of the backlight;

a cavity located between the rear surface of the electronic display assembly and the inner surfaces of the frame;
a plate positioned within the cavity, wherein said plate is configured to receive a plurality of electronic components;
a circulating gas pathway comprising said first gap and said cavity, wherein said circulating gas pathway is substantially sealed when the electronic display assembly is located in the closed position; and
an ambient gas pathway comprising the second gap;
wherein the access panel and the electronic display assembly are positioned in a back to back arrangement.

11. The field serviceable assembly of claim 10 wherein:
the electronic display assembly is mounted to an upper portion of the frame in a hinged fashion such that the electronic display assembly is configured to swing upward and outward.

12. The field serviceable assembly of claim 10 further comprising:
a touch input layer located in the electronic display assembly.

13. The field serviceable assembly of claim 10 wherein:
said access panel is configured to receive a poster.

14. The field serviceable assembly of claim 13 further comprising:
an illumination element configured to edge light said poster.

15. The field serviceable assembly comprising:
a frame having a front perimeter and a rear perimeter;
a first and second gasket extending along the front perimeter and the rear perimeter of said frame, respectively;
a first and second electronic display assembly, each mounted to an upper portion of the frame in a hinged fashion, wherein said first and second electronic display assemblies are oriented in a back to back arrangement, and wherein the first and second electronic display assemblies each comprise:
a transparent layer;
an electronic display;
a plate located behind the electronic display;
a gap defined by the space between the rear surface of the transparent layer and the front surface of the electronic display; and
a channel defined b the s ace between the rear surface of the electronic display and the plate;

a shared cavity located in the space between the rear surfaces of the first and second electronic display assemblies and the frame, wherein the shared cavity is in gaseous communication with the gap of the first and second electronic display assemblies;
a plate positioned within the cavity and configured to receive a plurality of electronic components;
a closed loop pathway comprising said shared cavity and said gap of said first and second electronic display assemblies;
a first open loop pathway comprising the channel of said first electronic display assembly;
a second open loop pathway comprising the channel of said second electronic display assembly; and
a first and second aid device configured to assist in movement of the first and second electronic display assemblies between an opened and a closed position.

16. The field serviceable assembly of claim 15 wherein:
said electronic display is a liquid crystal display.

17. The field serviceable assembly of claim 15 wherein:
the first and second aid devices are configured to temporarily secure the first and second electronic assemblies in the opened position or the closed position.

18. The field serviceable assembly of claim 15 further comprising:
mounting devices for mounting the assembly to the roof of a vehicle.
