Description of the invention: [Technical field to which the invention belongs] The present invention relates to a plasma display panel. More specifically, it refers to a method for improving the effect of anisotropic conductive film overflow glue and a plasma display panel. [Previous Technology] With the development of the electronic information industry, the use and demand of flat panel displays (FPDs) are constantly expanding, and plasma display panels (pDp) are among the various flat displays with considerable development potential. The conventional press manufacturing process of a flexible printing circuit (Fpc) in the latter stage of plasma display (PDP) is shown in Figure 1. Generally, an anisotropic conductive film (ACF) is used. As a connection medium, a flexible printed circuit board 1 (FPC) and a panel 2 (Panel) are laminated, and a flexible printed circuit board 1 (FPC) is used as a panel 2 and a driver. Electrical connection bridges between circuit boards are shown in invention patents such as US Patent No. 6472820 “Plasma display panel” and No. 6522073 “Plasma display panel with an auxiliary bonding pad”. As shown in Figure 2, the anisotropic conductive film 3 is mainly composed of a thermoplastic material such as bad epoxy resin (Epoxy) or polyethylene, and is usually made into a film, which contains many conductive particles 4 (nickel Ni, especially Gold-plated nickel, with a diameter of about 6-8μιη), so it can be softened by heat using hot pressing technology, and then directly cured to bond the flexible circuit board 1 and the panel 2 ', and the flexible circuit can be made in 1242787 The electrodes 5 and 6 between the plate 1 and the panel 2 achieve the effect of conducting current in the vertical direction. Secondly, as shown in FIG. 3, during the press-bonding process of the flexible circuit board 1 and the panel 2, the anisotropic conductive film 3 is melted and pressured without directional spreading between the two. Therefore, The overflow adhesive of the anisotropic conductive film 3 is often seen on the edge of the pressing position of the flexible circuit board 1 and the panel 2. After the press-fitting industry is completed, if the pressing position of the flexible circuit board 1 and the panel 2 is incorrect, which causes the electrodes of the panel 2 to be hollowed out, the electrodes are easy to move (Migration), which will affect the service life of the plasma display. Therefore, if the overflow adhesive of the anisotropic conductive film 3 can be covered on the electrodes of the panel 2, the electrodes of the panel 2 can be effectively protected and the service life of the plasma display can be prolonged. However, so far, no technology has been seen in the field of plasma display technology that guides the direction of the anisotropic conductive film and then covers the silver electrode surface of the panel. [Summary of the Invention] In view of the problems of the conventional technology above, the object of the present invention is to provide a method for improving the effect of anisotropic conductive film overflow glue applied to a plasma display panel, which can guide the anisotropic conductive glue overflow to the panel.
