Abstract
A driving circuit for a radio frequency plasma display panel that is capable of effectively making an impedance matching between a radio frequency signal generator and a panel. In the circuit, radio frequency electrode lines are divided into a plurality of groups. A plurality of impedance matchers are independently connected to each group of the radio frequency electrode lines to match impedance of input and output terminals thereof. Accordingly, an impedance difference between the radio frequency electrode lines caused by a length difference of radio frequency supply lines is uniformly compensated, so that a maximum power of radio frequency signal can be applied to each radio frequency electrode line to provide a stable operation of the panel as well as to improve a picture quality.
