Method for controlling a flat display screen

摘要

A method for controlling a cathodoluminescent screen consists of providing regeneration steps during which at least a portion of the anodes is at a low voltage and the corresponding cathodes are biased to an emission state. When the screen is a microtip color screen, regeneration steps are provided between the operation steps and, during the regeneration steps, all the anodes are at a low voltage, the microtips and the gates being biased to an emission state.
