Abstract

A driving method of a plasma display panel, in which a plurality of subfields for time-divided grayscale display exist in each frame of a display period, and each subfield includes a reset period, an address period and a discharge maintenance cycle. In the discharge sustain period, sustain pulses of the second potential voltage based on the first potential voltage are supplied to each of the Y electrode lines and the X electrode lines according to the Y electrode supply potential period and the X electrode supply potential period, respectively. Each Y pole power supply potential cycle and X pole power supply potential cycle include the rise time from the first potential voltage to the second potential voltage, the maintenance time for maintaining the second potential voltage, and the time for falling from the second potential voltage to the third level voltage. fall time. The interval time for maintaining the first potential voltage, and the interval time for the Y-electrode power supply potential cycle and the X-electrode power supply potential cycle interval time do not overlap with each other.

Description

[0001] priority statement [0002] This application refers to and incorporates the previous application No. 2003-86064 filed at the Korean Intellectual Property Office on November 29, 2003, entitled "Drive Method for Plasma Display Panel" and requires registration under 35 U.S.C119 the priority of the resulting 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 a...
