APPARATUS FOR DRIVING PLASMA DISPLAY PANEL AND ITS METHOD, IN WHICH A TRANSIENT PHENOMENON IS PREVENTED

摘要

PURPOSE: An apparatus for driving a plasma display panel and its method are provided to prevent a transient phenomenon according as changing a vertical frequency of an image signal inputted from the external. CONSTITUTION: The apparatus(2) for driving a plasma display panel comprises an image processor(26) and a control part(22) and a Y driver(25) and an address driver(23) and a X driver(24). The image processor generates an internal image signal by converting an analog image signal into a digital signal. The control part generates a driving control signal including a scan data signal and an address data signal and a common data signal according to the internal image signal. The Y driver applies a scan driving signal to Y electrode lines. The address driver applies an address driving signal to address electrode lines. And the X driver applies a common driving signal to X electrode lines.
