Embodiment Construction

[0038] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0039] The present invention is described in detail below with reference to the accompanying drawings, in which exemplary embodiments of the present invention are shown.

[0040] figure 1 A perspective view of a display device according to an embodiment of the present invention is shown. reference figure 1 , A plasma display panel (PDP) includes: an upper substrate 10; a plurality of electrode pairs formed on the upper substrate 10 and each including a scan electrode 11 and a sustain electrode 12; a lower substrate 20; and a lower substrate 20 on multiple address electrodes 22.

[0041] Each electrode pair includes transparent electrodes 11a and 12a and bus electrodes 11b and 12b. The transparent electrodes 11a and 12a may be formed of indium tin oxide (ITO). The bus electrodes 11b and 12b may be formed of metal s...

Abstract

A plasma display device is provided. In the plasma display device, a plurality of scan electrodes are divided into one or more scan electrode groups, and different driving signals are applied to the scan electrode groups. More specifically, a minimum voltage detected during a set-down period of a reset period is made to be discrepant from a scan voltage, thereby reducing the amount by which wall charge is erased and stabilizing an address discharge. In addition, different driving signals are applied to a plurality of scan electrodes, and thus, it is possible to stabilize an address discharge even in scan electrodes to which a scan signal is applied late.

Description

technical field [0001] The present invention relates to a plasma display device, and more particularly, to a driving signal for driving a plasma display panel included in the plasma display device. Background technique [0002] Generally, a plasma display panel (PDP) includes an upper substrate, a lower substrate, and a plurality of barrier ribs, wherein the barrier ribs are disposed between the upper substrate and the lower substrate and define a plurality of cells each filled with a main discharge gas , such as neon (Ne), helium (He) or neon, helium mixed gas (Ne+He), and inert gases containing a small amount of xenon. When a discharge occurs due to a high-frequency voltage, the inert gas generates vacuum ultraviolet (UV) rays, and the ultraviolet rays excite phosphor layers between barrier ribs, thereby realizing an image. The PDP is thin and light, and has been considered to be a mainstream next-generation display device. [0003] As the size and resolution of the PDP...
