New Electrode Structure for Reducing Power Consumption of Pdps

A new electrode structure for plasma-display panels (PDPs) is proposed, which decreases the panel capacitance by effectively decreasing the electrode area and increasing the discharge efficacy. Although the electrode area is decreased, the proposed structure does not require an increase in operating voltage and can improve the discharge efficacy by limiting the discharge current. The effect of panel capacitance reduction of the suggested electrode structure contributes to power-consumption reduction in the entire PDP system by reducing the dissipative power due to the charging current of the panel capacitance. The effects of panel-capacitance reduction by using the new electrode structure were confirmed by comparing the charging-current waveforms and directly measuring the capacitances of various panels with conventional and new electrode structures.
