Problems solved by technology

[0015] However, in the prior art as described above, sustain pulses of the same polarity (for example, positive polarity) are periodically applied to the Y electrode and the Z electrode, so excessive negative and positive electrodes are respectively accumulated in the Y electrode and the Z electrode. Sexual wall charge hinders sustain discharge and reduces discharge efficiency

Embodiment Construction

[0034] Hereinafter, preferred embodiments are given, and detailed descriptions are given in conjunction with the accompanying drawings.

[0035] image 3 Shown is the panel driving method in the first embodiment of the present invention. As shown in the figure, during the sustain period, sustain pulses with positive polarity voltage (+Vs) and negative polarity voltage (-Vs) are alternately applied to the Y electrode, and positive polarity voltages with a phase earlier than the sustain pulse are alternately applied to the Z electrode. Trigger pulses for voltage (+Vs) and negative polarity voltage (-Vs).

[0036] refer to image 3 The working principle of the above-mentioned driving method is explained in detail as follows.

[0037]During the reset period, positive polarity (+) wall charges are accumulated in the Y electrode, negative polarity (-) wall charges are accumulated in the Z electrode, and after the discharge cell is selected during the positioning period, positive ...

Abstract

A method for driving a plasma display panel(PDP) is provided to prevent a fluorescent material from being damaged due to excessive wall charges by preventing the wall charges from being excessively accumulated on respective electrodes. A PDP includes Y, Z, and X electrodes. One frame is divided into reset, address, and sustain periods. During the sustain period, a sustain pulse with a predetermined intensity is applied on the Y electrode. The sustain pulse alternates between positive and negative values. A triggering pulse is applied on the Z electrode before the sustain pulse is applied on the Y electrode. An application timing of the triggering pulse is sooner than the application timing of the sustain pulse by a predetermined phase. The triggering pulse alternates between positive and negative values.

Description

1. Technical field [0001] The present invention relates to a driving method of a plasma display panel, specifically a method of: alternately applying sustain pulses of positive polarity voltage and negative polarity voltage to the Y electrode, and alternately applying positive polarity voltage to the Z electrode before applying the sustain pulse The trigger pulse with the negative polarity voltage prevents the Y electrode and the Z electrode from excessively accumulating wall charges of a specific polarity and causing residual influence. Form an optimal amount of wall charges during the sustain discharge, so that sustain discharge can easily occur under low voltage conditions, and at the same time prevent excessive accumulation of charges of a specific polarity in the X electrode, and protect the plasma display of the phosphor The driving method of the panel. 2. Background technology [0002] Plasma Display Panel (PDP), which is attracting attention as a next-generation rep...
