Abstract
The present invention provides a driving circuit for driving a plasma display unit. The plasma display unit can be repeatedly charged for sustaining a display of an image signal. The driving circuit comprises two driving circuits, a control circuit, and a power supply. Each of the driving circuits comprises an inductor, two switches, and two diodes. Each of the switches comprises a transistor with a parasitic diode existed between a drain and source of the transistor. The plasma display unit is electrically connected between the two inductors. The control circuit is used for controlling the on and off states of the switches so that the power supply can repeatedly charge the plasma display unit through the two driving circuits.
