Problems solved by technology

[0013] However, in the driving of such an existing plasma display panel, the sustain pulse input on the scan electrode and the sustain electrode should have a high voltage that can sustain the sustain discharge of the cell, so the drive efficiency is low.

Embodiment Construction

[0034] Hereinafter, a plasma display device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0035] FIG. 3 is a block diagram illustrating a plasma display device in the present invention.

[0036] As shown in Figure 3, among the present invention, plasma display device comprises the data driver part (400) that provides data to the address electrodes (X1~Xm) of plasma display panel, the Y electrode driver part (400) that drives scanning electrode (Y1~Yn) 500), a Z electrode drive unit (600) for driving the sustain electrodes (Z), and a timing control unit (300) for controlling each drive unit (400, 500, 600).

[0037] The data driving part (400) selects data and provides the data to the address electrodes (X1~Xm) after being locked under the control of the timing control part (300).

[0038] In addition, the Y electrode driving unit (500) repeatedly inputs positive voltage pulses (+Vs / 2), ground vol...

Abstract

The invention is related to plasma display devices, which includes following parts: Y electrode driving part which repeatedly provides to Y electrode positive voltage pulse, ground voltage pulse and negative voltage pulse in maintaining period and between negative pulses inputs positive aided voltage pulse; Z electrode driving part which repeatedly provide negative voltage pulse, ground voltage pulse and positive voltage pulse in maintaining period, and between negative pulses inputs positive aided voltage pulse. The invention can reduce the voltage pulse level provided to Y electrodes and Z electrodes in maintaining period.

Description

technical field [0001] The present invention relates to a plasma display device, in particular, to a plasma display device in which driving efficiency is improved by reducing a sustain voltage level input during a sustain period. Background technique [0002] In general plasma display panels, the partitions between the front panel and the rear panel form units, and each unit is filled with main discharge gas such as neon (Ne), helium (He) or a mixed gas of neon and helium (Ne+He) and An inert gas containing a small amount of xenon (Xe). When the high-frequency voltage causes a discharge, the inert gas generates vacuum ultraviolet rays (Vacuum Ultraviolet rays) and makes the light formed between the partitions to display the picture. Such a plasma display panel can realize a thin and light structure, and thus is very popular as a next-generation display device. [0003] FIG. 1 is a schematic structural diagram of a general plasma display panel. A...
