Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] As shown in Figure 1-3.

[0025] A front plate of a shadow mask type plasma display panel comprises a glass substrate 1 as a front substrate, a silicon dioxide layer 2, a silver electrode 3, a dielectric layer 4 and a protective film 5. The silicon dioxide layer 2 is located between the glass substrate 1 and the silver electrode 3, and its thickness is greater than 10 μm, which is used to prevent the silver in the electrode from diffusing to the surface of the glass substrate during the whole process of making the glass front plate. The silicon dioxide layer 2 is coated on the tin-free surface of the glass substrate 1 as the front substrate, the dielectric layer 4 is covered on the silver electrode 3, and finally the dielectric layer 4 is covered with a protective film 5, as shown in Figure 1 .

[0026] Next, the method of manufacturing the fro...

Abstract

The invention aims at the problem that when metallic silver material is adopted to manufacture a bus electrode in the front board of a shadow mask type plasma body displaying board, the front board is easily dyed yellow; therefore the displaying contrast is reduced, the invention discloses a front board of a shadow mask type plasma body displaying board, namely, a glass front board which is not easily dyed, and the manufacture technology thereof. The front board of the shadow mask type plasma body displaying board comprises a glass base plate (1) used as the front substrate, a silicon dioxide layer (2), a silver electrode (3), a dielectric layer (4) and protective film (5); wherein, the silicon dioxide layer (2) is positioned between the glass base plate (1) and the silver electrode (3), so as to prevent the diffusion of the silver in the electrode to the surface of the glass base plate during the whole technical process of manufacturing the front board. The manufacture technology of the front board comprises the steps of silicon dioxide layer (2) manufacture through collosol-gel method and temperature control during each sintering process. The sintering temperature control is used for reducing the diffusion of the silver, and for further reducing the dyeing of the silver to the front board.

Description

technical field [0001] The invention relates to a front panel of a shadow mask type plasma display panel and a manufacturing method thereof, in particular to a display panel front panel capable of reducing yellowing of the front panel of a shadow mask type plasma display panel caused by making silver electrodes on float glass A panel and a manufacturing method thereof, specifically a shadow mask type plasma display panel front panel and a manufacturing method thereof. Background technique [0002] As we all know, a shadow mask plasma flat panel display (hereinafter referred to as SM-PDP) is composed of a front substrate, a rear substrate and a shadow mask, wherein the front substrate is mainly composed of a glass substrate, metal electrodes, a dielectric layer and a protective film. The glass substrate used in the SM-PDP front substrate is ordinary soda-lime glass or PD200 special glass, and the metal electrodes are made of metallic silver. However, the silver electrodes ma...
