Preferred embodiments relates to a cooling system and a method for cooling an electronic display. Embodiments include a transparent liquid cooling chamber, a reservoir tank, and a pump. The components in the system are preferably housed within the electronic display housing. The cooling chamber defines a fluid compartment that is anterior to and coextensive with the electronic display surface. Circulating coolant removes heat directly from the electronic display surface by advection. In order to view the display, the coolant fluid is transparent or at least semi-transparent. The image quality of an exemplary embodiment remains essentially unchanged, even though coolant is flowing over the visible face of the electronic display surface.

A system and method for cooling back to back electronic displays. Transparent first and second gas chambers are co-existive with the front display surfaces of the first and second electronic displays. A closed loop of isolated gas enters the first and second gas chambers and contacts the front surfaces of the electronic displays, where it may extract heat from the front display surfaces. The isolated gas is then directed into a cooling chamber where it is cooled and re-introduced into the first and second gas chambers. Fans may be used to propel the isolated gas through the cooling chamber and the first and second gas chambers. The circulating gas removes heat directly from the electronic display surfaces. The isolated gas is transparent or at least semi-transparent to ensure that the image quality of the electronic displays is minimally impacted.
