Asymmetric Resonant Poles Sustainer for Plasma Display Panel

A new plasma display panel (PDP) sustaining driver using asymmetric resonant poles is proposed. Since asymmetric resonant poles are used for inverting the panel voltage, the flexibility in the rising time and the falling time of the panel voltage is increased. Moreover, all sustain switches are turned on with zero-voltage and a voltage notch across the panel is significantly reduced. Since the proposed circuit is implemented with reduced component counts, it features a simple structure and low cost. The operation principle is presented in detail and a 7.5-in ac PDP equipped with the proposed circuit is investigated.
