1. An apparatus for preventing bowing of an electronic display comprising:
- a housing;
a cover panel, wherein the electronic display is located behind said cover panel;
a backlight located behind said electronic display; and
a closed loop pathway for circulating gas comprising;
a first gas pathway located between said cover panel and the electronic display;
a backlight cavity located between the electronic display and the backlight; and
a second gas pathway located behind the backlight;
wherein the closed loop pathway is configured to cause the pressure of circulating gas in the backlight cavity to be lower than the circulating gas in the first gas pathway.

15. An apparatus for preventing bowing of an electronic display comprising:
-
a housing; a cover panel, wherein the electronic display is located behind, spaced apart from, and substantially parallel to said cover panel; a backlight located behind, spaced apart from, and substantially parallel to said electronic display, wherein the space between the backlight and the electronic display defines a backlight cavity; a closed loop pathway for circulating gas encircling the electronic display and comprising the space between said cover panel and said electronic display, the backlight cavity, and a space between said housing and said backlight; an open loop pathway located in the space between said housing and said backlight; a first and second bracket located at an entrance and an exit, respectively, of the backlight cavity, wherein said first and second brackets define an entrance gap and an exit gap, respectively, for the circulating gas to enter or exit the backlight cavity, wherein the entrance gap is smaller than the exit gap; an angled section located on a distal end of the second bracket and extending towards the side of said housing; and a first and second support located at the entrance and the exit, respectively, of the backlight cavity, wherein said first and second supports define a second entrance gap and a second exit gap, respectively, for the circulating gas to enter or exit the backlight cavity, wherein the second entrance gap is smaller than the second exit gap. - View Dependent Claims (16, 17)
