Abstract
An apparatus and method for reducing or combating bowing of an electronic display layer located behind a cover panel is provided. A rear panel is positioned behind the electronic display layer. An air pathway includes a first gas pathway between said cover panel and the electronic display layer, a cavity located between the electronic display layer and the rear panel, and a second gas pathway located behind the rear panel. The air pathway is configured to cause the pressure of air in the cavity to be lower than the pressure of air in the first gas pathway.
Claims20
An apparatus for reducing or combating bowing of an electronic display layer, said apparatus comprising:
- a cover panel, wherein the electronic display layer is located behind said cover panel;
- a rear panel positioned behind the electronic display layer;
- and
- a closed loop pathway for circulating gas comprising:
- a first gas pathway located between said cover panel and the electronic display layer;
- a cavity located between the electronic display layer and the rear panel;
- and
- a second gas pathway located behind the rear panel;
- wherein the closed loop pathway is configured to cause the pressure of circulating gas in the cavity to be lower than the pressure of circulating gas in the first gas pathway.
The apparatus of claim of 1 wherein:
- the pressure of the circulating gas passing through the cavity is between 0 and 0.5 psi lower than the circulating gas passing through the first gas pathway.
A method for reducing or combating bowing of an electronic display layer, said method comprising the steps of:
- providing a cover panel, wherein the electronic display layer is located behind said cover panel, a rear panel positioned behind the electronic display layer, and a closed loop pathway for circulating gas comprising a first gas pathway located between said cover panel and the electronic display layer, a cavity located between the electronic display layer and the rear panel, and a second gas pathway located behind the rear panel;
- causing circulating gas to flow through the first gas pathway at a first pressure;
- and
- causing circulating gas to flow through the cavity at a second pressure, wherein the second pressure is lower than the first pressure.
An apparatus for reducing or combating bowing of an electronic display layer, said apparatus comprising:
- a cover panel, wherein the electronic display layer is located behind said cover panel;
- a rear panel positioned behind the electronic display layer;
- and
- an air pathway comprising:
- a first gas pathway located between said cover panel and the electronic display layer;
- a cavity located between the electronic display layer and the rear panel;
- and
- a second gas pathway located behind the rear panel;
- wherein the air pathway is configured to cause the pressure of air in the cavity to be lower than the pressure of air in the first gas pathway.
