Abstract

A method and apparatus for driving a plasma display panel for preventing generation of over current in the panel are disclosed. In the method, a scanning pulse falling from a first voltage is sequentially applied to a plurality of scan electrodes, and a data pulse is simultaneously applied to a plurality of address electrodes to select a cell. Said first voltage on the scan electrodes is lowered into a second voltage after said scanning pulse was applied to the scan electrodes in the last line. A time when said first voltage is lowered into said second voltage is controlled differently at any at least one of the scan electrodes.

Description

[0001] This application claims the benefit of Korean Patent Application No. P2003-59505 filed on Aug. 27, 2003, which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a plasma display panel, and in particular, to a method and apparatus for driving a plasma display panel, which are suitable for preventing an overcurrent from being generated in the panel. Background technique [0003] Generally, a plasma display panel (PDP) excites and irradiates a phosphor material using ultraviolet rays generated under discharge of a mixed inert gas such as He+Xe, Ne+Xe, or He+Ne+Xe, thereby displaying a picture. Such a PDP is easily manufactured as a thin film and large-sized type. In addition, the PDP can provide better picture quality because of recent technological development. [0004] Referring to FIG. 1 , a discharge cell of a conventional three-electrode AC surface discharge PDP includes scan electrodes 30Y and sustain el...
