Abstract:
1. A plasma display panel driving apparatus, comprising: a switching output circuit having upper transistors and lower transistors disposed in such a way that the common output line of an upper transistor and a lower transistor is connected to a corresponding Y electrode line; a capacitor connected directly between the common power line of all of the upper transistors in the switching output circuit and the common power line of all of the lower transistors in the switching output circuit; a reset/sustaining circuit coupled with Y-electrode lines, the reset/sustaining circuit to apply a reset waveform to the Y-electrode lines during a reset period and apply a sustain voltage signal to the Y-electrode lines during a sustain period; and a voltage terminal supplying a scan bias voltage to the capacitor, wherein a magnitude of the scan bias voltage is less than a magnitude of the sustain voltage signal.
