Problems solved by technology

[0010] Therefore, the ratio of the brightness of the brightest white peak peak white in the picture displayed on the above-mentioned plasma display panel to the dark brightness without discharge, that is, the contrast ratio (Contrast) cannot be improved.
[0011] That is, the luminance of the peak white display portion is mainly determined by the light generated when the sustain signal (S) is input, and the dark luminance is determined by the initial discharge caused by the input of the initial signal (R). The initial discharge at the initial signal will produce weak light, resulting in the inability to improve the contrast between light and dark
[0012] At the same time, due to the light generated by the above-mentioned initial discharge, the display of the relatively dark part is abnormal, so it is difficult to display the correct color on the plasma display panel.

Embodiment Construction

[0027] Hereinafter, a plasma display device according to the present invention will be described with reference to the drawings. 3a to 3b are diagrams illustrating driving waveforms of a plasma display panel in the present invention, and FIGS. 4a to 4b are diagrams illustrating embodiments of initialization waveforms input to a plasma display panel in the present invention.

[0028] In the present invention, the plasma display panel has a module composed of a plurality of address electrodes (X) arranged in the column direction, and a plurality of scan electrodes (Y) and sustain electrodes (Z) arranged in the horizontal direction. The scan electrodes correspond to the sustain electrodes, and one ends of the sustain electrodes are connected to each other and transmit the same voltage.

[0029] The module is formed by combining the front panel formed by the scan electrodes (Y) and the sustain electrodes (Z) alternately horizontally and the rear panel formed by the address electro...

Abstract

The invention relates to plasma display device and the driving method. Under the state of display device stopping image, it has a driving section that has driving waveform of address searching signal and holding signal. The method could decrease electric power consumption and improve tone ratio. It could avoid bright spot and improve image quality of plasma display panel.

Description

technical field [0001] The present invention relates to a plasma display device and a driving method thereof, in particular to a plasma display panel that only inputs an addressing signal and a sustain signal when displaying a stop image signal, thereby preventing an increase in dark brightness caused by initial discharge and improving the light-dark ratio A plasma display device and a driving method thereof. Background technique [0002] FIG. 1 is a structural diagram of a conventional plasma display panel. [0003] The plasma display panel is a display device that uses vacuum ultraviolet rays (VUV) generated during gas discharge inside the panel to excite fluorescent agents inside the panel to generate light, and is roughly formed by a front substrate (10) and a back substrate (20). [0004] The structure of a general plasma display panel is as shown in Figure 1, and the front panel substrate (10) is composed of a plurality of scan electrodes (1...
