Abstract: The present invention provides a spacer assembly (100) which is tailored to provide a secondary electron emission coefficient of approximately 1 for the spacer assembly (100) when the spacer assembly (100) is subjected to flat panel display operating voltages. The present invention further provides a spacer assembly (100) which accomplishes the above achievement and which does not degrade severely when subjected to electron bombardment. The present invention further provides a spacer assembly (100) which accomplishes both of the above-listed achievements and which does not significantly contribute to contamination of the vacuum environment of the flat panel display or be susceptible to contamination that may evolve within the tube. Specifically, in one embodiment, the present invention is comprised of a spacer structure (102) which has a specific secondary electron emission coefficient function associated therewith. The material comprising the spacer structure (102) is tailored to provide a secondary electron emission coefficient of approximately 1 for the spacer assembly (100) when the spacer assembly (100) is subjected to flat panel display operating voltages.

Abstract: A flat panel display including a wall (590) in one embodiment includes 98 % alumina and a refractory metal, such as, 2 % titania, for increased thermal conductivity. Alternatively, the refractory metal may be molybdenum, niobium, tungsten, or nickel. The wall may further include cordierite, or zirconia.

Abstract translation: 用于平板显示器的壁和用于形成具有改善的导热性和降低的电阻率热系数的平板显示器的壁的方法。 在一个实施例中，使用氧化铝，钼和二氧化钛制造壁。 将这些氧化物（氧化铝和二氧化钛）与金属氧化物混合并铸造，以形成然后加热的薄片材料。 加热过程将金属氧化物还原成其金属状态。 然后将所得的薄片材料切割成壁。 这产生具有比现有技术壁更高的导热性的壁。 此外，所得材料的电阻率的热系数显着低于用于制造壁的现有技术材料的热系数。 具有本发明的壁的平板显示器由于与壁相关的热效应而不显示可见显示的未照明区域。
