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

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown, the present invention provides a kind of MgO / ZnO composite dielectric protection film, and described composite dielectric protection film comprises ZnO nanowire, and the surface of described ZnO nanowire is provided with one deck MgO thin film, and wherein, the length of ZnO nanowire is 50 ~200nm, the thickness of the MgO thin film is 100~500nm. In the present invention, ZnO nanowires are grown on the surface of the substrate on which the ZnO seed layer is prepared by the water bath method, and the ZnO seed layer is obtained by magnetron sputtering, coating and spin coating or pulsed laser deposition; the MgO thin film is obtained by The reactive magnetron sputtering method is sputtered on the surface of ZnO nanowires.

[0033] The present invention also provides a method for preparing a MgO / ZnO composite dielectric protective film...

Abstract

The invention discloses an MgO / ZnO composite dielectric protection film and a preparation method thereof. The composite dielectric protection film comprises a ZnO nanometer wire; an MgO film layer is arranged on the surface of the ZnO nanometer. According to the MgO / ZnO composite dielectric protection film and the preparation method, a ZnO seed crystal layer is arranged on a substrate and produces the ZnO nanometer wire, then the MgO film is arranged on the surface of the ZnO nanometer wire by a depositing manner, and thus the roughness of the surface of the composite dielectric protection film is improved, and as a result, the secondary electron emission coefficients of the composite dielectric protection film are increased; the dielectric protection film with high secondary electron emission coefficients can effectively lower down the firing voltage of a display, and thereby, the power consumption and cost of a PDP (Plasma Display Panel) display are decreased to some extent, and as a result, the service life of a device is prolonged, and the stability of working voltage of the display is improved.

Description

technical field [0001] The invention belongs to the field of plasma displays, and in particular relates to a MgO / ZnO 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 excites the coating 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) discov...
