Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0025] figure 1 is a diagram showing an example of an electrode arrangement structure of a plasma display panel, and a plurality of discharge cells constituting a plasma display panel, such as figure 1 As shown, it is preferably arranged in a matrix. A plurality of discharge cells are provided at intersections of scan electrode lines (Y1 to Ym), sustain electrode lines (Z1 to Zm), and address electrode lines (X1 to Xn). The scan electrode lines (Y1 to Ym) may be driven sequentially or simultaneously, and the sustain electrode lines (Z1 to Zm) may be driven simultaneously. The address electrode lines (X1 to Xn) may be divided into odd-numbered and even-numbered rows for driving, or sequentially driven.

[0026] figure 1 The electrode configuration shown is just an embodiment of the electrode configuration structure of the plasma displ...

Abstract

A plasma display apparatus includes a transparent electrode formed on an upper substrate, a black layer formed on the transparent electrode, and a bus electrode formed on the black layer, wherein the bus electrode is in contact with the transparent electrode at the outside of the region where the black layer is formed. Thus, the resistance value of the electrodes is reduced, and accordingly the driving voltage is also reduced, thereby improving power efficiency. Further, the plasma display apparatus is able to achieve an entirely uniform screen display and improves light room contrast, thereby improving the merchantability of the product.

Description

technical field [0001] The present invention relates to a plasma display device, and more specifically, to a plasma display device having an electrode structure that improves the bright room contrast of a panel and reduces power consumption during driving. Background technique [0002] A plasma display panel (Plasma Display Panel, hereinafter referred to as PDP), applies a predetermined voltage to the electrodes in the discharge space to generate a discharge, and the plasma generated during the gas discharge excites the phosphor, thereby displaying an image containing characters or graphics , which has the following advantages: it is easy to achieve large-scale, light-weight and thin-plane, and it can provide a wide viewing angle in up, down, left, and right, and present full-color and high-brightness. [0003] Generally, in a plasma display panel, a predetermined voltage is applied to electrodes provided in a discharge space to generate discharge, and plasma generated durin...
