Abstract
An electrode assembly includes at least first and second electrodes for forming one or more dynamic quadrupole lenses to emit electron beams and an electron gun using the same. A first parabolic waveform signal having voltages decreasing from the center to the periphery of a screen on which the electron beams land is applied to the first electrode, and a second parabolic waveform signal having voltages increasing from the center to the periphery of the screen is applied to the second electrode, in synchronization with horizontal and vertical deflection signals for horizontally and vertically deflecting electron beams emitted from the electrode assembly.
