Embodiment Construction

[0060] Refer to the following Figure 5 to Figure 9f , the embodiment of the plasma display driving method and device in the present invention will be described in detail.

[0061] Figure 5 It is a display diagram of the plasma display driving device in the first embodiment of the present invention.

[0062] In the present invention, each discharge cell forms a pair of sustain electrodes, and the pair of sustain electrodes is at least divided into two or more sustain electrode groups of sustain electrodes and scan electrodes; mutually different numbers of sustain pulses are supplied to the sustain electrodes and scan electrodes. middle.

[0063] refer to Figure 5 The structure of the PDP driving device in the first embodiment of the present invention is as follows: the scan electrodes are divided into odd scan electrode lines and even scan electrode lines, and the sustain electrodes are divided into odd sustain electrode lines and even sustain electrode lines. The first ...

Abstract

The invention discloses plasma display screen activation method and device, which comprises the following steps: dividing the maintaining electrode double-group into more than two maintaining electrode group within maintaining electrode and scanning electrode; supplying different quantity of maintaining impulse to the maintaining electrode and scanning electrode. Each discharging unit of plasma display screen activation device forms the maintaining electrode double plasma display screen. The invention can display medium grey scale, which improves the grey scale appearance.

Description

(1) Technical field [0001] The invention relates to the technology of the plasma display screen; in particular, a driving method and device of the plasma display screen capable of improving gray scale performance. (2) Background technology [0002] The plasma display panel (P1asma Display Panel: hereinafter referred to as "PDP") uses the 147nm ultraviolet rays generated when the inert mixed gas such as He+Xe, Ne+Xe or He+Ne+Xe is discharged to make the phosphor emit light, so as to display the Images with text or illustrations. The above-mentioned PDP is not only easy to achieve thin film and large size, but also benefits from the recent technological development, which can provide more superior image quality. In particular, the three-electrode AC creeping discharge type PDP accumulates wall charges on its surface during discharge, and can protect the electrodes in the sputtering environment generated during discharge, so it has the advantages of low voltage driving and lon...
