ABSTRACT:
A highly-efficient device and method for driving a plasma display panel, by which the voltage stresses of circuit elements, which constitute the driving device, are significantly reduced, and power consumption and heat emission are accordingly reduced. Charging and discharging modes, which constitute a sustain mode, are divided into two first and second charging modes, which are pre-charging and post-charging modes, and two first and second discharging modes, which are pre-discharging and post-discharging modes, respectively. The plasma display driving device is designed so that the two charging modes form different resonance paths passing through different inductors, and the two discharging modes also form different resonance paths passing through different inductors. Consequently, voltage stresses applied to the elements of the driving device are halved. Therefore, high-performance low-priced semiconductor devices can be used to form the plasma display panel driving device, and the reactive power of a plasma display panel can be halved.
