This paper presents design and development of driving waveforms to improve efficacy, contrast, and resolution for ac plasma display panels (PDPs). In the paper, the conventional driving waveforms are first reviewed, and the proposed driving waveforms are then discussed. The driving of PDPs in each subframe is divided into three periods: the reset period, scan period, and sustain period. During the reset period, the proposed ramp-like reset waveforms can enhance the contrast and resolution, and can lower the scan voltage while still sustaining a reliable wall-charge control. Additionally, a square sustain waveform stacked with the ramp-like waveform can induce self-erasing discharges which will improve efficacy during the sustain period. Operation of a PDP and comparison among various driving waveforms are also presented. Experimental results measured from a 46-in PDP system have verified the feasibility of the proposed driving waveforms.
