Example Embodiment

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like figure 1 As shown, the present invention provides a MgO / ZnO composite dielectric protective film, the composite dielectric protective film includes a MgO film, and the MgO film is doped with ZnO nanoparticles dispersedly distributed. Among them, the thickness of the MgO film is about 171nm ( figure 1 a), the size of ZnO nanoparticles is about 10nm ( figure 1 b). In the present invention, ZnO nanoparticles are deposited by reactive magnetron sputtering method, and MgO film is sputtered on the surface of Si substrate by reactive magnetron sputtering method.

[0031] The invention also provides a preparation method of MgO / ZnO composite dielectric protective film, using the method of reactive magnetron sputtering to co-sputter MgO / ZnO composite thin film on Si substrate, and the reaction temperature is 160°C.

[0032] Specifically, a JPG-4...

Abstract

The invention discloses an MgO/ ZnO composite medium protecting film and a preparation method thereof. The composite medium protecting film comprises an MgO film in which diffusely distributed ZnO particles are doped. According to the MgO/ ZnO composite medium protecting film, the ZnO particles are doped in the MgO film, so that the shapes of the surface particles are changed from elliptic shapes into triangular shapes; the secondary electron emission coefficients of the composite medium protecting film are increased, the firing voltage of a display can be effectively reduced, and therefore, the power consumption and cost of a PDP display can be certainly reduced, the service life of a device can be prolonged, and the stability of the working voltage of a display device can be 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) display luminescence is 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 glow discharge excites the coating on the barrier. Phosphor powder emits red, green, and blue 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) discovered the...
