AC gas discharge display screen

Abstract

The present invention discloses an AC gas discharging display screen. There is the control electrodes, which are coated with a dielectric layer contg. low melting point glass and a fluorescent powderlayer in sequence, on a dielectric base plate in the screen. There is a dielectric barrier made of the material contg. low melting point glass between the control electrodes. A layer of supplementarydielectric made of high melting point material is added between the dielectric layer and the fluorescent power layer on the control electrode, and side wall of dielectric barrier and fluorescent powre to eliminate the interaction of the fluorescent power coating material and low melting point glass in heat treating so as to keep the high luminous efficiency of the fluorescent powder. The supplementary dielectric layer made of high melting point dielectric material of electron emitting material can lower the operation voltage.

Description

[0001] 1. Field [0002] The invention belongs to the technical field of gas discharge, in particular to a gas discharge display (PDP), which can be used to develop a display device containing an AC gas discharge display (PDP). 2. Background technology [0003] According to the literature and materials carried out by the applicant, the prior art materials related or close to this patent application include the following: [0004] 1. A known AC gas discharge display screen (PDP) has two dielectric substrates, wherein paired parallel display electrodes covered by a dielectric layer are arranged on one of the dielectric substrates, and control electrodes are arranged on the other dielectric substrate. The control electrodes are coated with a phosphor layer (European Patent Application for Invention N 0554172 HO1J17 / 49 1993]. The disadvantage of this display is the high control voltage due to the low charge accumulation in the dielectric covering layer on the electrodes. [0005]...

AI Technical Summary

Problems solved by technology

The disadvantage of the AC gas discharge display is the low brightness of the phosphor

This is due to the interaction between the phosphor powder and the low-melting glass component contained in the dielectric covering layer of the control electrode during the heat treatment process, resulting in a decrease in the luminous efficiency of the phosphor powder.
