Abstract
The disclosure described herein generally relates to an image panel and a method of compressing the image panel. A breather assembly is coupled to at least one edge of the image panel and a vacuum is drawn through the breather assembly to pull the image panel portion and the front panel into intimate contact with phosphors sandwiched therebetween. The breather assembly draws the vacuum from the air pockets between adjacent phosphors to pull the image panel flat and thus prevent image artifacts from forming while also permitting the image panel portion and the front plane panel to move independently.
