Study on the second-order sustaining driver for plasma display panel

Abstract

The sustaining driver for plasma display panel (PDP) should provide alternating high voltage pulses to ignite plasma and recover the energy stored in the intrinsic capacitance between the scanning and sustaining electrodes inside the panel. Second-order circuits utilizing the series connected or parallel-connected external inductance and intrinsic capacitance have been successfully adopted for the sustaining driver. In this way, high efficiency and low component count can be achieved. In this paper, the electrical characteristics of second-order drivers in the sustaining operation mode are investigated and influence of the ignited plasma discharging current on the driver performance is discussed.
