Abstract
A device for controlling an electrode of a flat display screen includes a first electrode constituting a microtip cathode, a second electrode constituting an anode provided with phosphor elements and a gate that is arranged in rows. At least one of the electrodes is arranged in columns. The device includes circuitry for individually addressing each column and for interrupting the biasing of a column as soon as its charge reaches a threshold voltage corresponding to a desired luminescence value.
