Abstract
A gas cooling system for an electronic display is disclosed herein. A closed loop of circulating gas is preferably positioned to surround the electronic display. An open loop of cooling air preferably travels along the rear surface of the electronic display. In an exemplary embodiment the cooling air does not mix with the circulating gas. Heat may be transferred from the circulating gas to the cooling air in order to cool the display.
