- a frame having an upper edge, a lower edge, a first side edge, and a second side edge;
a first and second display assembly, mounted to the frame in a back to back arrangement, wherein at least one of the display assemblies comprises;
a transparent layer;
an electronic display located behind the transparent layer;
a first channel configured to receive circulating gas; and
a second channel configured to receive ambient air;
a cavity defined by rear surfaces of the first and second display assemblies and the upper edge, the lower edge, the first side edge, and the second side edge of 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 surface of said first and second display assemblies, and wherein said fixed plate is configured to receive a plurality of electronic components;
a closed loop pathway comprising said cavity and said first channel; and
an open loop pathway comprising said second channel;
wherein each of said first and second display assemblies are mounted to said frame in a hinged fashion for movement between a closed position where said closed loop pathway, including said cavity, is sealed, and an opened position where said fixed plate is accessible.

Abstract
A field serviceable apparatus includes a first and second display assembly hingedly mounted to a frame in a back to back arrangement. At least one of the display assemblies has a transparent layer, an electronic display, a first channel that receives circulating gas, and a second channel that receives ambient air. A cavity is located in the space between the rear surfaces of the display assemblies and the frame and contains a fixed plate for receiving electronic components. The cavity and the first channel are part of a closed loop pathway, while the second channel is part of an open loop pathway.
