Claim 19:
20. A display assembly with divided interior space, said display assembly comprising:
a structural framework;
an intake located at an upper portion of said structural framework;
an exhaust comprising a first outlet located at a first side of a lower portion of said structural framework and a second outlet located at a second side of said lower portion of said structural framework;
a first and second electronic display subassembly, each attached to said structural framework and comprising:
a cover;
an electronic display layer comprising liquid crystals located behind said cover;
an illumination device comprising a number of light emitting diodes mounted to a substrate and configured to illuminate said electronic display layer when powered;
a closed loop passageway located between said cover and said illumination device for accommodating a flow of circulating gas; and
an open loop passageway located behind said illumination device for accommodating a flow of ambient air;
a common passageway located between the first and second electronic display subassembly and in fluid communication with said closed loop passageways of said first and second electronic display subassemblies;
a central septum comprising one or more angled surfaces extending and providing a fluid barrier within the common passageway between, and primarily in a direction perpendicular to a viewing surface of, the first and second electronic display subassemblies to fluidly divide the common passageway into a first portion and a second portion and to prevent the circulating gas from directly traveling between the first portion and the second portion, wherein said first portion is fluidly adjacent to an entrance to said closed loop passageway of said first electronic display subassembly and an exit to said closed loop passageway of said first electronic display subassembly such that the first portion is fluidly connected to the closed loop passageway of both of the first and second electronic display subassemblies, and wherein said second portion is fluidly adjacent to an entrance to said closed loop passageway of said second electronic display subassembly and an exit to said closed loop passageway of said second electronic display subassembly such that the first portion is fluidly connected to the closed loop passageway of both of the first and second electronic display subassemblies;
a first side septum extending laterally within the first portion of said common passageway;
a second side septum extending laterally within the second portion of said common passageway;
a first heat exchanger located within said first portion of said common passageway and secured to said first side septum;
a second heat exchanger located within said second portion of said common passageway and secured to said second side septum;
a closed loop airflow pathway comprising said closed loop passageways of said first and second electronic display subassemblies, said common passageway, a first portion of said first heat exchanger, and a first portion of said second heat exchanger; and
an open loop airflow pathway comprising said intake, said exhaust, said open loop airflow passageways, a second portion of said first heat exchanger, and a second portion of said second heat exchanger.
