吸气剂在解决平板新技术商业化开发过程中的主要技术问题：封装、可靠性和寿命方面起着至关重要的作用。平板显示器(FPD)的生产步骤通常包括长时间的烘焙和排气过程，以便在最终密封之前将杂质含量降至最低，这极大地增加了制造成本，最高可能达到与大规模生产要求不相容的水平。这些问题可以通过引入一种特殊的吸气剂装置来解决和解决，该装置可以通过形成不可逆的化学键永久地去除不需要的物种。在本文中，我们将重点介绍长期研究的平板显示器技术，如真空荧光显示器、场发射显示器和等离子体显示器面板，展示基于特殊金属合金的适当吸气剂解决方案如何提高其寿命和可靠性，特别是在某些情况下，还可以改善制造工艺条件。
Getters play a crucial role in solution of the main technical issues on the way to commercial exploitation of new flat-panel technologies: packaging, reliability and lifetime. The production steps of flat-panel displays (FPDs) often include a long baking and exhaust process to minimize the impurity content prior to the final sealing, which dramatically increases the manufacturing costs up to a level that might be incompatible with mass production requirements. These problems can be tackled and solved by the introduction of a specific getter device that can permanently remove the undesirable species by the formation of irreversible chemical bonds. In this paper we will focus on long-studied FPD technologies such as vacuum-fluorescent displays, field-emission displays, and plasma display panels, showing how proper getter solutions based on special metal alloys can increase their lifetime and reliability and, in particular cases, also improve the manufacturing process conditions.
