Abstract
A cooling system and a method for cooling an electronic display. A preferred embodiment utilizes a closed loop cooling system in a constricted convection cooling setup to remove heat from the backlight of a display assembly. Cooling air can be pulled or pushed through a gap between the display (or backlight) and a rear cooling chamber. The resulting warm air can then be exhausted out of the display housing. The cooling air may be air conditioned or may be exposed to a thermoelectric device. A thermostat may be used so that cooling fans are only energized when the temperature reaches a predetermined point.
