Abstract
An apparatus for driving an electron emission element driven by two different potentials applied thereto includes a scanning drive circuit for applying a first potential to the electron emission element, a modulating drive circuit for applying a second potential to the electron emission element, and a timing control circuit for providing a delay time following application of the first potential in order to delay application of the second potential. The delay time is set to be longer than a time required for the damping of a ringing waveform, which is produced by application of the first potential, to 1% of the applied voltage. This makes it possible to reduce the effects of the ringing phenomenon.
