Abstract
Provided is a PDP driving apparatus for reducing electromagnetic interference (EMI) generated during operation of a PDP. The PDP driving apparatus drives a PDP with X electrodes and Y electrodes arranged parallel to each other, and Address electrodes arranged to cross with the X electrodes and the Y electrodes to form discharge cells. The PDP driving apparatus includes a frequency lowering unit coupled between an X electrode and a ground terminal or between a Y electrode and a ground terminal. The frequency lowering unit includes a capacitor with capacitance between about 1 nF and about 2 nF, and lowers a resonance frequency caused by parasitic capacitance and inductance components of the PDP driving apparatus.
