平板CRT的发展趋势

The Development Trend for Flat CRTs

CRT器件是当前显示器件中技术最为成熟应用最为普及的主导产品。由于存在着体积大、重量重等固有的严重缺陷 ,CRT器件也一直受到众多新型平板显示器件的严峻挑战。实现 CRT器件的平板化设计 ,一直是 CRT科研工作者不断努力和艰苦工作的目标。本文简要叙述了平板 CRT的发展经历、主要类型及工作原理 ,并进一步探讨了平板 CRT的发展前景。

CRT is a leading product in electron display devices at present ,since it holds some mature manufacturing techniques and enjoys the widestuse.However,CRT has been met with some severe challenge from many new flat- panel display devices because CRT has some serious defects such as a greater bulk and a heavier weight and so on.Ithas long been the goal of the display researchers throughout the world to achieve a new CRT design that is both flat and thin .In this paper,the history of the developmentfor flat CRTs,and their main models as well as their operating principles are briefly introduced,and their development trend is also discussed.
