Problems solved by technology

That is, in a high-temperature environment, the recombination ratio of wall charges and discharge space charges increases, resulting in the loss of wall charges, and the problem of misdischarge will become more serious.
Even, it will cause the discharge cell (cell) that should be turned on to be turned off, and the problem that the image cannot be displayed

Abstract

The present invention relates to a plasma display device, and more specifically, relates to a plasma display device and a driving method thereof for adjusting a positive waveform voltage negatively applied to a sustain electrode, improving discharge accuracy, and improving jitter characteristics . As described above, the plasma display device in the present invention includes: a plasma display panel including sustain electrodes; a sustain drive unit that drives the sustain electrodes; and controls the sustain drive unit so that subfields (frame) During the falling edge period of sub-field) and the positioning period or during any one of the positioning periods, the positive polarity waveform voltage applied to the above-mentioned sustain electrode is changed from the first voltage level to the second voltage level with a certain gradient. The drive pulse control unit.

Description

technical field [0001] The present invention relates to a plasma display device, more specifically, to a plasma display device and a driving method thereof for adjusting a negative waveform voltage of a positive polarity applied to a sustain electrode. Background technique [0002] A general plasma display panel consists of a unit discharge cell (cell) formed by the interlayer formed between the front substrate and the back substrate, and each cell (cell) is filled with neon (Ne), helium (He), or neon and Main discharge gas such as mixed gas of helium (Ne+He) and a small amount of inert gas containing xenon. When the high-frequency voltage causes discharge, the inert gas generates vacuum ultraviolet rays (Vacuum Ultraviolet ray), which makes the phosphors formed between the interlayers emit light and display images. Such a plasma display panel has a light and thin structure, and is attracting attention as a next-generation display device. [0003] FIG. 1 is a schematic str...
