DRIVING METHOD FOR GAS DISCHARGE PANEL

PURPOSE:To improve the luminance and duty ratio by performing the trickle discharge of a cell with maintaining pulses by using a single wide pulse. CONSTITUTION:Pulses having a potential -VT1 are applied to an auxiliary electrode and pulses having a potential VS1 are applied to a maintaining electrode to cause discharge between the auxiliary electrode and maintaining electrode, thereby performing trigger setting. Then scanning pulses having a potential Vk are applied to cathodes K1-Kn in line sequence and write pulses having a potential VA are applied to an anode. In a maintaining period, the single wide pulse which has a potential VS3 and nearly covers the entire maintaining period is applied to the maintaining electrode. Charged particles resulting from write discharge remain at a selected cell nearby the cathode of the barrier and inter-positive-column discharge wherein the maintaining pulses (potential VS3) are applied is caused between the maintaining electrode and the cathodes, so that the discharge is carried on for the maintaining period. The discharge is continuously carried out without interruption in the discharge maintaining period to improve the luminance and duty ratio.
