Method for generating short-duration pulses on a plurality of columns or rows of a plasma display and device for implementing said method

摘要

The present invention relates to a method and a device for generating pulses of amplitude A and duration T on a plurality of columns of a PDP. The method comprises the following steps:- during a first phase, applying a DC voltage across the terminals of a solenoid (L) so that the latter stores current,- during a second phase, applying a voltage of amplitude A across the terminals of the capacitors of the PDP columns and discharging into the latter a part of the current stored in the solenoid up to the point where the voltage across the terminals of the columns of the display reaches the amplitude A,- during a third phase, maintaining said voltage of amplitude A across the terminals of the display columns so as to create a discharge current between the columns and the rows of the PDP cells in the written state and bringing the current stored in said solenoid to zero,- during a fourth phase, charging the solenoid with the current stored in the capacitors of the PDP columns until the voltage across the terminals of the latter becomes zero,- during a fifth phase, bringing the current stored in the solenoid to zero.
