1. An electronic display assembly comprising:
- a liquid crystal display having a direct LED backlight with a rear surface;
a plate having a front side facing the direct LED backlight and a rear side opposing the front side, where the plate is spaced apart from the rear surface of the LED backlight to define a channel therebetween;
an electronic component located along the rear side of the plate; and
a fan positioned to draw cooling air through the channel;
wherein the cooling air is prohibited from contacting the electronic component.

Abstract
Exemplary embodiments provide an electronic display assembly. One or more heat-generating components are preferably placed in thermal communication with a plate. One or more fans are placed to draw cooling air along the plate to remove the heat removed from the component. Some embodiments may place the plate behind the electronic image assembly, so that cooling air can remove heat from the plate as well as the electronic image assembly. Exemplary embodiments have power modules in thermal communication with optional conductive ribs. Conductive thermal communication is established between the optional ribs and the components in the exemplary embodiments.
