Problems solved by technology

In the case where a drive plate is formed at each electrode, there is a disadvantage in that electromagnetic interference (EMI) or crosstalk is caused by a phase error of pulses applied between the respective electrodes
In addition, the manufacturing cost of the plasma display device is increased
In addition, the disadvantage is that the noise of the driving waveform increases because the output impedance increases due to the use of high-voltage switches

[0119] According to the first embodiment of the present invention, when the sustain pulse (SUSP) is supplied to the scan electrode (Y), the first switch unit (SW1) is turned on, and when the sustain pulse (SUSP) is supplied to the sustain electrode (Z) , the second switch unit (SW2) is turned on.

[0120]In the first embodiment of the switching sequence, the first and second switching units (SW1 and SW2) can be kept turned on during a duration substantially equal to the duration of supplying the sustain pulse (SUSP).

[0121] In other words, the sustain pulse (SUSP) is supplied to the scan electrode (Y) by turning on the first switch unit (SW1), and the sustain pulse (SUSP) is supplied to the sustain electrode (Y) by turning on the second switch unit (SW2). electrode (Z).

[0122] Figure 7 is to illustrate the second embodiment according to the present invention Figure 4 A view of the switching timing of the plasma display device.

[0123] Such as Figure 7 as shown, ...

Abstract

Provided are a plasma display apparatus and a driving method thereof. The apparatus comprises a plasma display panel, and a single sustain driving board. The plasma display panel comprises a scan electrode and a sustain electrode. The single sustain driving board comprises a single energy recovery circuit unit and a single sustain pulse creation unit. The single energy recovery circuit unit supplies energy for supplying a sustain pulse through a same energy storing unit and a same inductor to the scan electrode and to the sustain electrode. The single sustain pulse creation unit supplies the sustain pulse to the scan electrode and to the sustain electrode.

Description

technical field [0001] The present invention relates to a plasma display device and a driving method thereof. Background technique [0002] Generally, in a plasma display panel, barrier ribs formed between a front panel and a rear surface form a unit cell. Each cell is filled with a main discharge gas such as neon (Ne), helium (He) or a mixture of neon and helium (He+Ne) and an inert gas including a small amount of xenon (Xe). When discharge is performed using radio frequency voltage, the inert gas generates vacuum ultraviolet rays, and radiates the fluorescent material disposed between the barrier ribs, thereby expressing an image. Because of its thinness and light weight, the plasma display panel has become a highlight of next-generation display devices. [0003] figure 1 is a view illustrating the existing connection relationship between the plasma display panel and the driver. [0004] Such as figure 1 As shown, the front panel 151 and the rear panel 152 are sealed ...
