Numerical Analysis the Performance of Field Emission Display with Secondary Electrons Emission

In this paper, we calculated and compared the performance of three different structures of CNT-FED: a normal triode structure, a double-gate structure, and a structure with insulator channel. By calculating the electrical field and the electron trajectories, we found that the normal triode structure is easy to induce pixel-pixel interference; while the double-gate structure subtract the anode current because of the interception of the second gate. In the structure with insulator channel, the disadvantages mentioned above can be avoided. Furthermore, when the cathode has some defects, the uniformity of the anode current can be improved because of the secondary electrons generated at the surface of the insulator wall
