Embodiment Construction

[0050] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0051] In the PDP driving method according to the embodiment of the present invention, in order to control the state of the wall charge in the discharge cell of the PDP, which represents the gray level by the subfield including the reset period, the address period and the sustain period, applying the normal The voltage waveform of the wall charge state is set to prevent unintentional strong discharge from initialization discharge cells during the reset period, so that the reliability of the reset period can be improved, the reliability of grayscale representation can be improved, and the contrast of the display screen can be increased.

[0052] Figure 7 is a perspective view of PDP1.

[0053] refer to Figure 7 , address electrode line A 1 、A 2 ,...A m , the first and second dielectric layers 102 and 110, the Y electrode line Y 1 ...

Abstract

A driving method for a plasma display panel in which gray-scale levels are represented by a combination of sub-fields. The method includes, during a reset period of a first sub-field, applying a rising ramp pulse and a falling ramp pulse to a first electrode, thus initializing wall charges of a discharge cell, wherein a self-erase discharge is generated if a strong discharge occurs between the first electrode and a second electrode, and during a reset period of a second sub-field, applying a falling ramp pulse to the first electrode.

Description

[0001] Cross References to Related Patent Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2004-0076328 filed September 23, 2004, which is incorporated herein by reference. technical field [0003] The present invention relates to a driving method of a plasma display panel (PDP), and more particularly, to a PDP driving method for initializing wall charges even when a strong discharge occurs unintentionally during a reset period. Background technique [0004] FIG. 1 shows an electrode structure of a plasma display panel (PDP). [0005] Referring to Figure 1, the scanning electrode line Y 1 , Y 2 ,...,Y n and common electrode line X 1 、X 2 ,...,X n (These electrode lines may be referred to as 'sustain electrode lines') are disposed in parallel on the PDP. Set address electrode line A 1 、A 2 ,...,A m , so that it is connected with the scan electrode line Y 1 , Y 2 ,...,Y n and common electrode line X 1 、X 2...
