Abstract
An electronic display assembly is disclosed herein. An electronic display may be positioned within a housing where the display is cooled by a combination of airflows. A closed loop of isolated gas may be used with an open loop of ambient air which passes through the housing in order to cool the display. Preferably, the closed loop of isolated gas cools the front surface of the display while the open loop of ambient air cools the rear surface of the display. Preferably, the closed loop of isolated gas is not permitted to mix with the open loop of ambient air.
Claims23
An electronic display assembly comprising:
- an electronic display housing;
- a gas-containing closed loop gas cooling chamber located within the electronic display housing;
- an electronic display positioned within the electronic display housing but outside of the closed loop gas cooling chamber;
- and
- an open loop ambient air pathway through the electronic display housing;
- wherein the electronic display is coolable by a combination of gas circulation within the closed loop gas cooling chamber and ambient air flow through the open loop ambient air pathway in the electronic display housing.
An electronic display assembly comprising:
- a housing;
- a liquid crystal display (LCD) positioned within the housing and having a backlight;
- wherein the electronic display is coolable by a combination of a closed loop of isolated gas which circulates within the housing and an open loop of ambient air which passes through the housing and along the backlight.
An electronic display assembly comprising:
- a housing;
- an electronic display positioned within the housing;
- a rear cooling chamber positioned behind the electronic display and containing an electrical component which is electrically connected to the electronic display;
- a front surface on the electronic display which faces an intended viewer and a rear surface on the electronic display which opposes the front surface;
- wherein the front surface of the electronic display is coolable by a closed loop of isolated gas and the rear surface of the electronic display is coolable by an open loop of ambient air.
An electronic display assembly comprising:
- an electronic display housing;
- a closed loop of cooling gas adapted for circulation within the electronic display housing;
- an open loop ambient air pathway through the electronic display housing;
- and
- an electronic display positioned within the electronic display housing such that the electronic display is isolated from the closed loop of cooling gas but contactable by ambient air flowing through the open loop ambient air pathway;
- wherein the electronic display is coolable by a combination of closed loop cooling gas circulation within the electronic display housing, and ambient air flow through the open loop ambient air pathway in the electronic display housing.
