Abstract: A method for cooling an electronic display is disclosed herein. The electronic display preferably contains a rear surface, where a substantially planar surface is positioned adjacent to the rear surface to define a gap. Cooling air is preferably forced through said gap. In some embodiments, the additional step of circulating gas around the display in a closed loop may also be performed. In these embodiments the circulating gas may contact the front viewing surface of the electronic display, so that heat can be removed from this surface.

Abstract: An electronic display having one or more thermal plates in thermal communication with an image assembly and a thermally-conductive housing (and optional door frame). In some embodiments, the thermal plate is in thermal communication with the door frame which is in thermal communication with the housing. A channel may be defined between a transparent plate assembly and the image assembly where a fan may force cooling air through the channel. The cooling air may also pass through apertures in the thermal plate(s). An exemplary image assembly may provide an LED edge-lit LCD or an OLED display. In some embodiments, two displays may be provided in a back-to-back orientation within a single housing. The display may dissipate heat without the need to ingest ambient air.

Abstract: Disclosed is a liquid crystal display (LCD) device having a good heat radiating function. Surface areas of a lower cover, an upper cover, and a guide panel are increased by forming grooves at the lower cover, the upper cover, and the guide panel. Heat generated from an optical source is rapidly radiated through the lower cover, the upper cover, and the guide panel having increased surface areas. This may prevent temperature increment of a backlight unit.

Abstract: 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.
