Abstract (en)

[origin: EP1445756A2] Conventionally, the drive means are suitable for generating charge-equalization or reset operations, then address operations and then sustain operations: the invention relates to division of the reset operations into two successive steps: —‹ a metastable space charge-generation step P1; —‹ an accelerated charge-generation end step P2 during which the system operates in the mode with weak discharges between the electrodes E1, E2, serving at least for addressing. Thanks to this division, the reset operations may be shortened and the luminous performance of the panel and/or the manufacturing yields of plasma panels may be improved.
