Internal support structure for flat panel device

A flat panel device, comprising:

• a faceplate;
• a backplate connected to the faceplate to form a sealed enclosure;
• means for emitting light from the flat panel device;
• and
• a spacer structure situated within the enclosure and supporting the backplate and the faceplate against forces acting in a direction toward the enclosure, a plurality of spacer structure holes extending through the spacer structure.

A flat panel device comprising:

• a first faceplate;
• a second faceplate connected to the first faceplate to form a sealed enclosure;
• first light-emissive material situated over the first faceplate;
• second light-emissive material situated over the second faceplate;
• a cathode;
• and
• a spacer situated within the enclosure and supporting the first faceplate and the second faceplate against forces acting in a direction toward the enclosure.

A flat panel device comprising:

• a faceplate;
• a backplate connected to the faceplate to form a sealed enclosure;
• means for emitting light from the flat panel device;
• an addressing grid situated between the faceplate and the backplate, a plurality of addressing grid holes extending through the addressing grid;
• a first plurality of cathode spacer walls situated within the enclosure between the addressing grid and the backplate, each cathode spacer wall having a greater thickness adjacent the backplate than adjacent the addressing grid;
• and
• a second plurality of anode spacer walls situated within the enclosure between the addressing grid and the faceplate.
