APPARATUS FOR DRIVING SCAN ELECTRODE FOR USE IN AC PLASMA DISPLAY PANEL AND METHOD FOR DRIVING SAME

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for driving a scan electrode for use in an AC plasma display panel and a method for driving the same that make the structure of a scan electrode driving circuit simple and reduce the manufacturing unit prices, and are advantageous for thermal loss of a switch and the generation of a sustain pulse due to the conduction of a current.;SOLUTION: The apparatus includes a power recovery block for supplying power to a panel capacitor to apply a waveform to generate a sustain discharge and for reusing recovered power by recovering the supplied power; a ramp pulse application block for supplying a pulse to initialize the state of each cell in a reset period; and a scan pulse generation block for supplying a pulse signal to accumulate wall charges in a discharge cell addressed during a scan period. A first current path through which the ramp waveform application block transmits pulses to reset states of respective cells to the panel capacitor and a second current path through which power is recovered from the panel capacitor are separated from each other.;COPYRIGHT: (C)2008,JPO&INPIT
