1. An electronic display comprising:
- an electronic image assembly having a front portion and a rear portion;
an open loop ambient air flow path behind the rear portion of the electronic image assembly;
a closed loop gas circulation path about the electronic image assembly;
a common heat exchanger located in the pathway of both the closed loop gas circulation path and the open loop ambient air flow path;
a gas circulation device positioned to force circulating gas through the common heat exchanger; and
an air circulation device positioned to force ambient air through the common heat exchanger.

Abstract
An electronic display including an electronic image assembly and a cooling system for an electronic image assembly. A closed loop gas circulation path and an open loop ambient air flow path are provided to effectuate cooling. A common heat exchanger is located in gaseous communication with both the closed loop gas circulation path and the open loop ambient air flow path. The open loop ambient air flow path facilitates removal of heat from gas circulating within the closed loop gas circulation path. A cooling channel may be located behind a rear portion of the electronic image assembly to further enhance cooling via the circulation of ambient air therein.
