Floating Single Sustain Method of Driving Plasma Display Panel

DoctorThis thesis presents a method of driving plasma display panel. This method uses a circuit ground for the sustain pulse generator separated from the system ground during the sustain period, so it is named the floating single sustain method. A drive waveform and cost-effective circuit, which requires four voltage levels of , , , and , for the floating single sustain method are proposed, and a cost-effective method of connecting the drive circuit to the electrodes of a PDP is presented. Experimental results on a 42-inch WVGA single-scan PDP show that the proposed waveform and circuit are well suited for driving the PDP, the problems of the unwanted S-D face discharge in the previous single sustain method and the sustain power leakage to the data drive circuit in the EX drive method are solved, and the power consumption due to the sustain power leakage to the data drive circuit is eliminated
