Isolated gas cooling system for an electronic display
First Claim
1. A gas cooling system for an electronic display enclosed within a housing, said electronic display having a display surface and a backlight having a rear surface, the system comprising:
- a first gas chamber positioned anterior to the electronic display surface;
a second gas chamber in sealed gaseous communication with said first gas chamber and positioned posterior to the electronic display surface;
a cooling chamber fan within said second gas chamber to propel circulating gas around the first and second gas chambers; and
a second fan positioned to force ambient air from outside of the housing over the rear surface of the backlight.

Abstract
A preferred embodiment relates to a cooling system and a method for cooling an electronic display. Exemplary embodiments include a transparent gas cooling chamber. The components in the system are preferably housed within the electronic display housing. The cooling chamber defines a gas compartment that is anterior to and coextensive with the electronic display surface. Fans may be used to propel the isolated gas through the cooling chamber. The circulating gas removes heat directly from the electronic display surface by convection. The isolated gas is transparent or at least semi-transparent. The image quality of an exemplary embodiment remains essentially unchanged, even though the gas is flowing through a narrow channel over the visible face of the electronic display surface.

15. An isolated gas cooling system for a liquid crystal display (LCD) enclosed within a housing, said LCD having a display surface and a LED backlight panel, the system comprising:
-
a first glass plate; a second glass plate laminated to the first glass plate and placed in front of the LCD display surface, the space between the glass plates and LCD display surface defining a channel; an anti-reflective coating applied to any one of the following;
first glass plate and second glass plate;a cooling plenum in gaseous communication with the channel to form an isolated closed loop; a first fan positioned so as to circulate gas through the channel and cooling plenum; and a second fan positioned so as to force ambient air from outside of the housing between the cooling plenum and the backlight panel. - View Dependent Claims (16, 17)
