Problems solved by technology

Although these designs have improved the performance of the dielectric protective film to varying degrees, they still cannot meet the performance requirements of AC-PDP for the dielectric protective film. Therefore, the research on the modification of the dielectric protective film still needs to be improved.

Embodiment Construction

[0032] The following examples are further detailed descriptions of the present invention.

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 with figure 2 As shown, the present invention provides a MgO / Ag composite dielectric protective film, and the composite dielectric protective film includes a MgO thin film and a MgO / Ag thin film. A layer of MgO / Ag composite dielectric protective film is provided on the surface of the MgO, wherein the thickness of the MgO film is 215nm, and the thickness of the MgO / Ag composite dielectric protective film is 30nm. The grain size of elemental Ag nanoparticles is 10nm. In the present invention, the MgO thin film is sputtered on the Si surface by a reactive magnetron sputtering method, and the MgO / Ag composite thin film is sputtered on the MgO thin film surface by a magnetron co-sputtering method.

[0035] The invention provides a method for preparing a...

Abstract

The invention discloses a MgO / Ag compound dielectric protective film and a preparation method thereof. Simple substance Ag nanoparticles are doped in a compound dielectric protective MgO film in a scattered mode. Due to the fact that the classic electron emitter simple substance Ag nanoparticles are doped in the MgO film, on one hand, a secondary electron emission coefficient is improved, on the other hand, the roughness of the surface of the compound dielectric protective film is improved, the firing voltage of a displayer is effectively reduced, power consumption and cost of the PDP displayer are reduced to a certain degree, the service life of a device is prolonged, and the stability of the work voltage of the display device is enhanced.

Description

technical field [0001] The invention relates to the technical field of plasma displays, in particular to a MgO / Ag composite dielectric protective film and a preparation method thereof. Background technique [0002] PDP (Plasma Display Panel, Plasma Display Panel) displays light based on the principle of gas discharge. When a certain voltage is applied between the electrodes, the inert gases Ne and Xe are broken down, and the visible light or ultraviolet light generated by the glow discharge is excited and coated on the barrier. The fluorescent powder emits red, green, and blue three primary colors of light, thereby realizing the color display of the PDP. When the additional voltage between the electrodes on the PDP substrate increases to a certain critical value, the inert gas between the electrodes will discharge, and the instantaneous voltage Vf at which the discharge starts at this time is called the ignition voltage. The famous German scientist Paschen (Paschen) discove...
