Plasma display device

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, different scan bias voltages are applied to the scan electrodes during a scan period, and different signals are applied to the scan electrodes during a set-down period of a reset period. Therefore, it is possible to stabilize an address discharge in scan electrodes to which scan signals are 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 partition walls arranged between the upper substrate and the lower substrate and defining a plurality of cells, each of which is filled with a material such as neon (Ne) , the main discharge gas of helium (He) or a mixed gas of neon and helium (Ne+He), and an inert gas 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 UV rays excite phosphor layers between partition walls, thereby realizing an image. The PDP is thin and lightweight, and has long been expected to become a dominant next-generation display device. [0003] As the size and resol...
