Abstract

This paper proposes a real-time wall charge measurement circuit for three-electrode AC PDP. It includes a charge-compensation network, current-integrating capacitors, initializing switches, and an op-amp. With this equipment, we measure the wall charge variations for the effects of sustain voltage, sustain pulse width, sustain frequency, and neighboring cells.
