场致发射显示是一种新型的平板显示技术，场致发射显示器继承了传统的阴极射线管显示器的优良特性，兼有液晶等薄型平板显示器的优点，具有广阔应用前景。介绍了几种不同阴极结构的场发射显示器工作原理及相应的驱动电路，分析并比较了二极管型和三极管型两种场致发射显示器的驱动电路，对新型场致发射平板显示器的理论研究具有参考意义。

Field emission display is a new type of flat panel display technology. It has a broad prospect which inherits the excellent characteristics of traditional cathode ray tube display, and also has the advantages of liquid crystal display as well as other thin panel display. Several cathode structures and working principle of field emission display and corresponding driving circuits are introduced in this paper. The field emission display driving circuits of the diode and triodic type are compared as well.
