Plasma display panel manufacturing method and manufacturing device

Abstract

Provided is a plasma display panel manufacturing method which simplifies a manufacturing step by lowering a film formation temperature so as to easily obtain an oriented MgO film as a protection layer. Moreover, the manufactured device has a simple structure so as to reduce the tact time. The method is used for manufacturing a plasma display including a front substrate having a scan electrode, a sustain electrode, a dielectric layer, and a protection layer; and a back substrate having an address electrode, a barrier rib, and a fluorescent body. The temperature of a front glass substrate before deposition by an electron beam deposition device is kept at a normal temperature (120 degrees C or below) and the MgO film formation speed of the electron beam deposition device is set not smaller than 8000AA m / min. By the film formation at the normal temperature, it was possible to obtain an MgO film equivalent to the film formation at a high temperature.

Description

technical field [0001] The present invention relates to a manufacturing method and manufacturing apparatus of a plasma display panel (hereinafter referred to as PDP), and particularly relates to formation of a protective layer of a dielectric layer. Background technique [0002] The AC surface discharge PDP, which is the mainstream of current PDPs, includes a front substrate made of scan electrodes, sustain electrodes, a dielectric layer, and a protective layer, and a back substrate made of address electrodes, barrier ribs, and phosphors (refer to Figure 20 ). [0003] like Figure 20 In the shown AC surface discharge type PDP 81, two glass substrates are welded and sealed via a narrow space filled with discharge gas. On rear glass substrate 90 , address electrodes 89 are arranged along the column direction, and dielectric layer 87 is formed thereon. The dielectric layer 87 functions as a protection of the address electrode 89 and a white inversion layer to improve brightn...

Problems solved by technology

[0012] However, since the process of forming the base and the process of forming the protective layer are required, two processes are required, and the conditions of the two processes are also different, so it cannot meet the recent demand for greatly improving productivity.
