Background technology
Field-emitter display (FED) is the another kind of flat-panel monitor of new generation that has development prospect most after LCD (LCD), plasma scope (PDP) etc. as a kind of novel flat-panel monitor.It is fast that FED has high-resolution, high-contrast, wide visual angle, response speed, and high-low temperature resistant, antidetonation, low radiation and production cost are lower, are easy to realize 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 made up of negative electrode and anode voltage, and negative electrode is emitting electrons 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 is formed, and negative electrode is emitting electrons under the regulation and control of grid electric field, the fluorescent material on the bombardment anode and luminous.

Three-stage structure can be divided into front gate type FED, back grid type FED and parallel gate type FED etc. according to the difference of gate location.Front gate type FED is owing to distance between grid and the negative electrode is little, and required modulation voltage is lower, need not to carry out high-voltage modulation on the anode, but preceding grid structure fabrication complex process be difficult for the realization large tracts of land and show, and the device emission uniformity is difficult to guarantee.Back grid type FED is embedded in grid under the negative electrode, utilizes the highfield of grid and cathode edge, makes the emissive material of cathode edge produce the electronics emission, and still, negative electrode is directly exposed under the anode electric field, and anode voltage should not be too high, otherwise can cause the emission of two utmost point formulas.And this structure must be dwindled the distance between negative electrode and the anode in order to prevent crosstalking of adjacent cells, has limited the raising of anode voltage, is unfavorable for improving the luminous efficiency of fluorescent material.The parallel distribution with grid of negative electrode at grade among the parallel gate type FED; Emissive material is distributed on the negative electrode; Be vacuum state between negative electrode and the grid, adopt the disposable making that just can on substrate, accomplish negative electrode and grid of common exposure technology and etching technics.In addition, insulating barrier is only required the place, crosspoint that is distributed in cloudy grid rank scanning in the parallel gate structure, and the grid-control performance of device and emitting performance do not receive the influence of insulating barrier, greatly reduce the complexity and the difficulty of technology.Because manufacture craft is simple, cost is much smaller than preceding grid and back grid structure, so a kind of three-stage structure of the parallel gate structure the easiest realization large tracts of land demonstration that is FED.
The patent of at present existing lot of F ED panel construction aspect, but less to the drive circuit that each structure designed, drive circuit is the important component part of FED display system, has determined the performance of FED display to a great extent.
