Abstract
Disclosed herein is an electronic display assembly having a thermally conductive housing and an image assembly. The image assembly is positioned within the thermally conductive housing and behind a transparent plate assembly. An inlet opening and outlet opening are formed by gaps located between opposing edges of the image assembly and the housing. A space between the image assembly and the plate assembly forms a channel. Thermally conductive plates extend from near the image assembly within each of the inlet opening and outlet opening to contact the housing. Heat from the image assembly is conductively transferred to the housing by the thermally conductive plates. A fan may be positioned to circulate cooling air through the channel via the inlet and outlet openings and apertures in the thermally conductive plates.
