Abstract

A method and apparatus for driving a plasma display panel is disclosed which can prevent the occurrence of erroneous discharge causing generation of bright defects. In accordance with the method and apparatus, the time interval between a final sustain pulse finally applied in a sustain period and a sustain pulse immediately preceding the final sustain pulse is set to be in a range of 0.1 mus to 1.0 mus, to reduce the amount of wall discharges erased during a period in which a low-level voltage is simultaneously applied to scan and sustain electrodes. Accordingly, the driving margin of the erasing discharge occurring in the next erasing address period is widened. Thus, it is possible to prevent the occurrence of erroneous discharge in the OFF cell, and thus, generation of bright defects, thereby achieving an enhancement in the display quality of the plasma display panel.

Description

technical field [0001] The present invention relates to a driving method of a plasma display panel and a device thereof, in detail, to a driving method and a device of a plasma display panel capable of stabilizing the discharge of an erasing address and preventing misdischarge of bright spots when the plasma display panel is driven by a selective erasing method . Background technique [0002] Plasma display panels use 147nm vacuum ultraviolet rays (VUV) generated during He+Xe, Ne+Xe or He+Ne+Xe gas discharge to make phosphors emit light, thereby displaying images including text or graphics. This plasma display panel is easy to achieve thin film reduction and size increase, and provides greatly improved image quality with recent technological development. [0003] As the plasma display panel, a three-electrode alternating current (AC) surface discharge type plasma display panel has three electrodes in each discharge cell, and reduces the voltage required for discharge by uti...
