Background technology
Field-emitter display (FED) is the another kind of flat-panel monitor of new generation that has development prospect most after liquid crystal display (LCD), plasma scope (PDP) etc. as a kind of novel flat-panel monitor.FED has high-resolution, high-contrast, wide visual angle, fast response time, and high-low temperature resistant, antidetonation, low radiation and production cost are lower, are easy to realize the characteristics such as digitlization demonstration, have wide market application foreground.
Field-emitter display can simply be divided into diarch FED and triple-pole type FED according to structure.Diarch FED mainly is comprised of negative electrode and anode voltage, and negative electrode is electron emission under the effect of anode electric field, the fluorescent material of bombardment on the anode and luminous; Triple-pole type FED mainly contains negative electrode, grid and anode forms, and negative electrode is electron emission under the regulation and control of grid electric field, the fluorescent material on the bombardment anode and luminous.
