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 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 pulses,...

Abstract

The plasma display based on X pole and Y pole and Z pole input pulse during initial period, address inquiring and maintaining to input Vs and -Vs voltage pulse to maintain the sustainable discharge, comprises repeatedly providing positive voltage pulse, grounding voltage pulse and negative voltage pulse to Y pole during maintenance, inputting positive voltage pulse to above Y pole driving section to provide negative pulse, Z pole input negative pulse to provide positive voltage pulse, inputting positive assistant voltage pulse before inputting negative voltage pulse to the Z pole, and inputting negative assistant voltage pulse to the Z pole drive section before inputting to the positive voltage pulse. It can reduce the voltage level to Y and Z pole, in order to improve the driving efficiency of the plasma.

Description

technical field [0001] The present invention relates to a plasma display device, and more specifically, it relates to a plasma display device in which driving efficiency is improved by lowering an input sustain voltage level during a sustain period. Background technique [0002] In general, the partitions formed between the front panel and the rear panel in a plasma display panel become units, and each unit is filled with main components such as neon (Ne), helium (He) or a mixed gas of neon and helium (Ne+He). Discharge gas and 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 di...
