Problems solved by technology

However, the above-mentioned shadow mask type plasma display panel has the following problems: ① The introduction of the conductive mesh increases the capacitance of the display screen, affects the high-frequency response characteristics of the display screen, and is not conducive to high-speed addressing and high-capacity display
②Because the shadow mask has good thickness uniformity and high precision, it is closely attached to the front and rear substrates, which is not conducive to gas circulation, so the process time is prolonged when the vacuum is obtained, which is not conducive to improving production efficiency

Abstract

The invention discloses a low-capacitance plasma display panel, mainly including a front substrate and a back substrate as well as a conductive shadow mask between the two substrates, which supports them and contains a grid array, where each grid vertically intersects the addressing and scanning electrodes to form basic discharge units. Its characteristic: there are through grooves in the positions where the back of the conductive shadow mask corresponds to the addressing electrodes on the back substrate. Relative to the existing shadow mask type plasma display panel, it has lower display screen capacitance and high gas conductance, thus reducing power loss, increasing working response frequency of device and shortening manufacturing cycle.

Description

technical field [0001] The present invention relates to a plasma display panel, and more particularly to a shadow mask type plasma display panel.
