Back to back electronic display assembly
The exemplary embodiments herein comprise a back to back electronic display assembly having a first display assembly positioned back to back with a second display assembly. A plenum is preferably positioned in between the first and second display assemblies with a first gap defined between the plenum and the first display assembly and a second gap defined between the plenum and the second display assembly. A fan is preferably positioned to force air through the first and second gaps. A plenum fan may be used to circulate air around the plenum. Preferably, the second display assembly can move relative to the first display assembly to provide access to the interior of the plenum.
1. A back to back electronic display assembly comprising:
a first display assembly positioned back to back with a second display assembly;
an enclosed chamber positioned entirely between the first and second display assemblies, wherein said enclosed chamber is substantially sealed to prevent circulating air located within the enclosed chamber from exiting the enclosed chamber;
a first gap defined between the enclosed chamber and the first display assembly;
a second gap defined between the enclosed chamber and the second display assembly; and
a fan positioned to force external air through the first and second gaps.
2. The assembly of claim 1 further comprising:
a chamber fan positioned within the enclosed chamber.
3. The assembly of claim 1 wherein:
one or more electronic components for operating the first display positioned within the enclosed chamber.
4. The assembly of claim 3 wherein:
the electronic component is a power module.
5. The assembly of claim 1 wherein:
the enclosed chamber comprises a first wall and second wall which oppose each other, a top wall, bottom wall, and a pair of sidewalls.
6. The assembly of claim 5 further comprising:
a gasket positioned between the top wall and the second wall.
7. The assembly of claim 1 wherein:
the second display assembly is permitted to move relative to the first display assembly.
8. The assembly of claim 5 wherein:
the first wall is fixed relative to the first display assembly; and
the second wall is fixed relative to the second display assembly.
9. The assembly of claim 5 wherein:
the first gap is further defined between the first wall of the enclosed chamber and an LED backlight for the first display assembly; and
the second gap is further defined between the second wall of the enclosed chamber and an LED backlight for the second display assembly.
10. The assembly of claim 1 further comprising:
a first dividing wall positioned within the enclosed chamber; and
a second dividing wall positioned within the enclosed chamber and oriented substantially perpendicular to the first dividing wall.
11. The assembly of claim 10 further comprising:
a chamber fan positioned within the first or second dividing wall.
12. A back to back electronic display assembly comprising:
a first LED backlit display positioned back to back with a second LED backlit display;
an enclosed chamber positioned entirely between the first and second LED backlit displays and comprising:
a first wall which faces a first LED backlight,
a second wall which faces a second LED backlight,
a top wall,
a bottom wall, and
a pair of sidewalls which extend between the first wall and the second wall,
wherein said enclosed chamber is substantially sealed from external air;
a first gap defined by the space between the first wall and the first LED backlight;
a second gap defined by the space between the second wall and the second LED backlight;
an electronic component attached to the first wall or second wall;
a first fan positioned to force external air through the first gap and the second gap;
a dividing wall positioned within the enclosed chamber that connects between the first wall and second wall of the enclosed chamber;
a second fan positioned on the dividing wall for moving circulating gas through the enclosed chamber; and
an additional dividing wall within the enclosed chamber which is connected to the first dividing wall and connects between the first wall and second wall of the enclosed chamber.
13. The assembly of claim 12 wherein:
the first wall is fixed relative to the first display; and
the second wall is fixed relative to the second display.
