Embodiment Construction

[0020] Specific embodiments of the present invention are described in more detail below with reference to the accompanying drawings.

[0021] A plasma display device comprising: a plasma display panel having sustain electrodes and data electrodes crossing the sustain electrodes; a first driver for supplying a positive sustain pulse and a negative sustain pulse to the sustain electrodes in a sustain period, and a second A driver for supplying a positive voltage to the data electrode before the application time point of the positive sustain pulse.

[0022] The sustain electrodes may include scan electrodes or sustain electrodes.

[0023] The first driver may maintain a ground level voltage in the scan electrodes or the sustain electrodes without applying the positive sustain pulse and the negative sustain pulse to the scan electrodes or the sustain electrodes in the sustain period.

[0024] The second driver may maintain the positive voltage applied to the data electrodes at a ...

Abstract

A plasma display apparatus includes a plasma display panel, a first driver, and a second driver. The plasma display panel includes a sustaining electrode and a data electrode intersecting the sustaining electrode. The first driver supplies a positive sustain pulse and a negative sustain pulse to the sustaining electrode in a sustain period. The second driver supplies a positive voltage to the data electrode prior to an application point of time of the positive sustain pulse.

Description

technical field [0001] This document relates to display devices, and more particularly, to plasma display devices. Background technique [0002] Generally, a plasma display panel has a front panel and a rear panel. Barrier ribs formed between the front panel and the rear panel form unit discharge cells. Each cell is filled with an inert gas including a main discharge gas, such as neon (Ne), helium (He), or a mixed gas of Ne+He, and a small amount of xenon (Xe). A plurality of unit cells form one pixel. For example, a red (R) cell, a green (G) cell, and a blue (B) cell form one pixel. [0003] If the unit discharge cell is discharged by applying a high-frequency voltage thereto, it generates vacuum ultraviolet rays, which excite fluorescent materials formed between the barrier ribs, thereby realizing an image. [0004] The plasma display panel includes a plurality of electrodes, for example, scan electrodes Y, sustain electrodes Z, and data electrodes X. A driver for sup...
