Embodiment Construction

[0028] Preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0029] A plasma display device according to an embodiment of the present invention includes: a plasma display panel including scan electrodes, sustain electrodes, and address electrodes; a scan driver that supplies a first pulse to the scan electrodes during a sustain period; supplying a second pulse to the sustain electrode during the period, the second pulse and the first pulse being alternately supplied; and a data driver, which changes the polarity of the first pulse during the sustain period in response to the first pulse and the second pulse A third pulse opposite in polarity to the second pulse is supplied to the address electrodes.

[0030] The first and second pulses may have negative polarity and the third pulse may have positive polarity.

[0031] A voltage magnitude of the first pulse and a voltage magnitude of the second pulse may ...

Abstract

A plasma display apparatus and a method of driving the same are disclosed. The plasma display apparatus includes a plasma display panel including a scan electrode, a sustain electrode and an address electrode, a scan driver, a sustain driver and a data driver. The scan driver supplies a first pulse to the scan electrode during a sustain period. The sustain driver supplies a second pulse to the sustain electrode during the sustain period. The second pulse and the first pulse are alternately supplied. The data driver supplies a third pulse of a polarity opposite a polarity of the first pulse and the second pulse to the address electrode during the sustain period corresponding with the first pulse and the second pulse.

Description

technical field [0001] The present application relates to a display device, and more specifically, to a plasma display device and a driving method thereof. Background technique [0002] Among various display devices, a plasma display device includes a plasma display panel and a driving device for driving the plasma display panel. [0003] A plasma display panel includes a front panel, a rear panel, and barrier bars formed between the front panel and the rear panel. These barrier ribs form a unit discharge cell or a plurality of discharge cells. Each discharge cell is filled with a main discharge gas such as neon (Ne), helium (He), and a mixture of neon Ne and helium He, and an inert gas including a small amount of xenon (Xe). [0004] A plurality of discharge cells forms one pixel. For example, a red (R) discharge cell, a green (G) discharge cell, and a blue (B) discharge cell form one pixel. [0005] When the plasma display panel is discharged by a high-frequency voltag...
