ABSTRACT:
A driving circuit for the sustain waveforms of plasma display panel (PDP) includes voltage clamping and energy recovery. The PDP functions as an equivalent capacitor having X and Y sides. A Scan IC has a transistor QH coupled between a first terminal of the Scan IC and the Y side and a transistor QL coupled between a second terminal of the Scan IC and the Y side. The first terminal of the Scan IC is coupled with a first voltage source. A first switch is coupled to coupled to the second terminal of the Scan IC, a second switch is coupled between a second voltage source and the X side, and a third switch is coupled with both the X side and a fourth switch. The fourth switch is also coupled to the second terminal of the Scan IC and serially to an inductor, a fifth switch, and ground.
