摘要 |
According to the invention, a flat panel device includes a spacer for providing internal support. In one embodiment, the spacer is made of ceramic, glass-ceramic, ceramic reinforced glass, devitrified glass, metal with electrically insulative coating or high-temperature vacuum-compatible polyimide, and can be a spacer wall, a spacer structure including a plurality of holes, or some combination of a spacer wall, spacer walls, and spacer structure. Spacer surfaces are treated to reduce secondary emissions and prevent charging of the spacer surfaces. The flat panel device can include a thermionic cathode or a field emitter cathode, and the faceplate and backplate can both be straight or both be curved. The flat panel device can include an addressing grid.
