14.1: Electron Trajectory Analysis of Surface Conduction Electron Emitter Displays (SEDs)

Electron trajectories in surface conduction electron emitter displays (SEDs) are analyzed based on the multiple scattering model. Besides calculating beam spot patterns on the phosphor by the ray tracing method, simple formulae for calculating beam spot size and electron emission efficiency are proposed. It is shown that these calculations reproduce experimental results. Using these simulation methods, we can easily estimate electron emission characteristics in the SEDs.
