Abstract

The invention provides a plasma display screen medium protection film and a manufacturing method thereof, and a plasma display screen. The medium protection film comprises a magnesium oxide layer and an insulation oxide layer arranged at an upper surface of the magnesium oxide layer, wherein materials of the insulation oxide layer are selected from one group or multiple groups of material groups composed of SiO2, TiO2, ZnO, BaTiO3 and Al2O3. According to the medium protection film, the magnesium oxide layer is at a bottom layer, the insulation oxide layer is at a top layer, the magnesium oxide layer is protected by the insulation oxide layer from being polluted when being exposed in the air during subsequent processing operation, so stability of a magnesium oxide protection film is improved, moreover, in a discharging process, the insulation oxide layer has small thickness and has poor sputtering resistance capability, the insulation oxide layer is liable to remove through sputtering, the magnesium oxide layer at the lower layer performs the role, the discharging voltage of the plasma display screen is reduced, and light emitting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of gas discharge, in particular to a dielectric protective film of a plasma display, a preparation method thereof and a plasma display containing the same. Background technique [0002] Plasma display (PDP) is a kind of display that uses gas discharge to generate ultraviolet rays, and then excites phosphors to emit visible light to form images. The plasma display panel is the main structure for realizing discharge light emission, and it consists of two substrates, the front and the back. On the front substrate, there are horizontal sustain electrodes and scan electrodes, and a dielectric layer and a dielectric protective film thereon; on the rear substrate, there are vertical address electrodes and barrier rib structures. The discharge occurs in the space formed by the front and rear substrates and barrier ribs. The discharge performance of the plasma display panel determines the brightness, light efficien...
