1228242 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a plasma display panel, and particularly to a positioning structure of a display panel. [Previous technology] Plasma display is a thin display. Its main feature is that it can achieve an ultra-large size and ultra-thin screen to save a lot of screen space. The light emitting principle of the plasma display is similar to that of a fluorescent lamp. An inert gas is injected into a vacuum glass tank, and the inert gas generates a plasma effect by means of voltage pressure to emit ultraviolet rays. At this time, the ultraviolet rays are irradiated onto the surface of the glass tank wall The fluorescent material above can make the fluorescent material excite visible light of red, green or blue. In this way, the screen of the electric paddle display is composed of hundreds of thousands of units capable of emitting light by themselves, and each light emitting unit includes small bulbs of three colors of red, green and blue (R, G, B). The combination produces different colors, and then forms a display day surface. As shown in Figure 1, the plasma display includes a front plate 100 and a rear plate 102, but when the front plate 100 and the rear plate 102 are sealed at high temperature, the sealing material 10 The softening of 4 causes the front plate 100 and rear plate 102 to slip, or alignment errors due to improper control of the alignment and assembly process. [Summary of the Invention] In view of this, in order to solve the above problems, an object of the present invention is to provide a positioning structure of a display panel, which can improve the alignment error of the plasma display panel and increase the sealing accuracy.
