Plasma display device and driving method thereof

Abstract

A plasma display device and a driving method thereof are provided to stably drive a plasma display panel by applying erase pulses to scan electrodes, sustain electrodes, and address electrodes. A plasma display device includes a plasma display panel(400) and a driving unit(410,420,430). The plasma display panel includes a plurality of scan electrodes, a plurality of sustain electrodes, and a plurality of address electrodes. The driving unit supplies erase pulses to the scan electrodes, the sustain electrodes, and the address electrodes after a sustain period. The erase pulses applied to the scan electrodes are different from the erase pulses applied to the sustain electrodes and the address electrodes.

Description

1. Technical field [0001] The present invention relates to a plasma display device and a driving method thereof, in particular to a plasma display device and a driving method thereof for stably operating a plasma display panel by improving the waveform of an erasing pulse. 2. Background technology [0002] The diaphragm formed between the front panel and the rear panel of a general plasma display panel forms a unit, and each unit is injected with a cycle such as neon (Ne), helium (He) or a mixture of neon and helium (Ne+He). Inert gas with inert discharge gas and a small amount of xenon. When the high-frequency voltage is discharged, the inert gas will generate vacuum ultraviolet rays (Vacuum Ultraviolet rays), which will make the phosphors formed between the partitions emit light and display images. Such a plasma display panel is thin and light, and is popular as a next-generation display device. [0003] figure 1 It is a structural diagram of a general plasma display pa...

Problems solved by technology

[0014] Accordingly, the anode charge accumulated on the X electrode after the erasing interval varies from unit to unit, and there is a risk of misdischarge; and, in order to increase the margin of the next addressing voltage, an appropriate anode charge needs to be deposited on the X electrode. However, the elimination pulse input on the Z electrode is mainly determined by the surface discharge of the Y electrode. Therefore, there is a limit to properly eliminating the anode charge on the X electrode.
