Abstract
A driving circuit for producing sustain waveforms of a plasma display panel (PDP) is mentioned. The driving circuit includes the functions of voltage clamping and energy recovery. By controlling switches contained in the driving circuit, the supplied voltage source can be made to be only half of the sustain voltage. The voltage stress of some components will therefore be lower. In addition, the numbers of components can be reduced in the driving circuit.
