In this case, however, if the discharge gas is included at 10% or more, the sustain voltage or the address voltage inevitably increases together, even increasing the reactive power, without actually improving the discharge efficiency

Abstract

The plasma display panel includes upper and lower panels having a low dielectric constant. By adjusting factors such as the width of electrodes and barrier ribs in an optimum range, it is possible to reduce panel capacitance and improve the efficiency of sustain discharge or address discharge.

Description

technical field [0001] The present invention relates to plasma display panels (PDPs), and more particularly, to PDPs capable of reducing panel capacitance. Background technique [0002] A PDP is one in which discharge cells are formed between a rear substrate having barrier ribs formed thereon and a front substrate of a panel rear substrate, and when an inert gas in each discharge cell is discharged by a high-frequency voltage, generation Devices that irradiate fluorescent materials with vacuum ultraviolet light to allow images to be displayed. [0003] FIG. 1 is a perspective view showing the structure of a general PDP, and FIG. 2 is a cross-sectional view showing a discharge cell of the general PDP. [0004] First, a discharge cell is formed by a plurality of barrier ribs 24 partitioning a discharge space on the rear substrate 18 facing the front substrate 10 . [0005] Address electrodes X are formed on the rear substrate 18 , and scan electrodes Y and sustain electrode...
