Abstract

A method of driving a plasma display panel in which a plurality of sub-fields for time division gray-scale display exist in each frame which is a display period, and each of the sub-fields includes a reset period, an address period and a discharge-sustaining period. In the discharge-sustaining period, a sustaining pulse of a second level voltage based on a first level voltage is supplied to each Y-electrode line and X-electrode line according to a Y-supplied electrical-potential period and an X-supplied electrical-potential period. Each Y-supplied and X-supplied electrical-potential period includes a rising time to rise from the first level voltage to the second level voltage, a sustaining time to sustain the second level voltage, and a falling time to fall from the second level voltage to the first level voltage. An intermittent time to sustain the first level voltage, an intermittent time of the Y-supplied electrical-potential period, and an intermittent time of the X-supplied electrical-potential period do not overlap each other.

Description

[0001] priority statement [0002] This application refers to and incorporates the previous application No. 2003-86064 filed in the Korean Intellectual Property Office on November 29, 2003, entitled "Drive Method for Plasma Display Panel" and claims to be produced under 35 U.S.C 119 the priority of the application. technical field [0003] The present invention relates to a driving method of a plasma display panel (PDP), and more particularly, relates to a driving method of a PDP having a high-frequency overlapping time-continuation structure, wherein the above-mentioned structure is used to provide each X pole and Y pole Sustaining pulses in the discharge sustaining period overlap with each other, and the overlapping time period can be adjusted so that the emission efficiency is improved and the discharge sustaining time period is reduced. Background technique [0004] In a three-electrode surface discharge PDP, the address electrode line A R1 、A G1 ,...,A Gm and A Bm ...
