Embodiment Construction

[0021] Hereinafter, the plasma display device of the present invention will be described in detail with reference to the accompanying drawings.

[0022] Fig. 1 is a photograph showing an example of a plasma display panel of the present invention in a perspective view.

[0023] As shown in FIG. 1 , a plasma display panel includes scan electrodes 11 and sustain electrodes 12 , which are sustain electrode pairs formed on an upper substrate 10 , and address electrodes 22 formed on a lower substrate 20 .

[0024] Usually, the pair of sustain electrodes 11, 12 includes transparent electrodes 11a, 12a and bus electrodes 11b, 12b formed of indium tin oxide (Indium-Tin-Oxide; ITO), and the bus electrodes 11b, 12b may be made of silver (Ag) , metals such as chromium (Cr) or a laminated form of chromium / copper / chromium (Cr / Cu / Cr) or a laminated form of chromium / aluminum / chromium (Cr / Al / Cr). The bus electrodes 11b, 12b are formed on the transparent electrodes 11a, 12a, and function to re...

Abstract

A plasma display apparatus is provided to enhance the efficiency of energy by reducing heat radiation generated from a switch using a snubber circuit. A plasma display apparatus includes a source capacitor(Cs), resonance inductors(L1,L2), first and second switches(er_up,er_dn), and snubber circuits(520,530). The resonance inductors form a resonance circuit between the source capacitor and the capacitor of a plasma display panel. The first and second switches control the supplement and recovery of energy between the source capacitor and plasma display panel. The snubber circuits, which are connected between the resonance inductors and source capacitor, include a capacitor and at least one of a resistor and an inductor.

Description

technical field [0001] The present invention is an invention related to a plasma display device, more specifically, a plasma display device in which a sustain pulse is provided to a plasma display panel by a sustain driving device. Background technique [0002] A plasma display panel (Plasma Display Panel; hereinafter referred to as "PDP") excites phosphors to emit light by vacuum ultraviolet rays (VUV) generated when an inert gas mixture is discharged, thereby displaying images. [0003] Among them, the above-mentioned PDP is not only easy to thin and large, but also has a simple structure, so it is easy to manufacture and has the advantages of high brightness and luminous efficiency compared with other flat-panel display devices. In particular, the AC surface discharge type 3-electrode plasma display panel accumulates wall charges on the surface during discharge and protects the electrodes from sputtering caused by discharge, so it has the advantages of low voltage driving...
