Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the conventional screen printing vacuum suction method cannot fix the shadow mask. According to the shadow mask is a pure iron material, a soft magnetic plate with magnetism is designed to stick the shadow mask on the soft magnetic plate. A method, as attached figure 2 , and use vacuum to fix the soft magnetic board and shadow mask on the printing table

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 , 2 shown.

[0014] A method for fixing plasma display shadow mask screen printing. First, put soft magnetic plate 3 on glass 1 and place it on a platform, place shadow mask 4 flatly on glass 2, lift glass 2 and place it on a soft plate. Above the magnetic plate 3, one side of the glass 2 and the shadow mask 4 is first dropped on the soft magnetic plate 3 and the shadow mask edge is fixed, then the glass 2 is drawn flat quickly so that the shadow mask 4 is flatly pasted on the soft magnetic plate 3. Then lift the glass 1, transfer the soft magnetic plate 3 with the shadow mask 4 onto the printing workbench, and fix the soft magnetic plate with vacuum suction to start printing.

[0015] The invention adopts the combination method of vacuum and magnetic force to fix the shadow mask on the printing workbench, which solves the pr...

Abstract

A method for fixing the shadow mask of a plasma display screen during screen printing, which aims at the problem that the vacuum suction method cannot fix the shadow mask during conventional screen printing, and adopts a method of combining vacuum and magnetic force to fix the shadow mask. The soft magnetic board, and the method of flat drawing glass is used to paste the shadow mask on the soft magnetic board flatly, which solves the problem that the shadow mask will be distorted and deformed when the shadow mask is directly attached to the soft magnetic board due to its extremely thin and easy deformation. , the problem of damaging the shadow mask. The method is simple, reliable and easy to implement.

Description

technical field [0001] The invention relates to a plasma display, in particular to a method for manufacturing a plasma display shadow mask, in particular to a method for fixing the plasma display shadow mask during screen printing. Background technique [0002] At present, SMPDP is a new type of shadow mask type surface discharge AC-PDP. In its structure, the shadow mask is used to replace the barrier ribs in traditional PDP production, which saves the complicated process of making tall and narrow barrier ribs on the rear substrate, and at the same time divides the entire screen manufacturing process into a combination of three independent components, as shown in the attached Figure 1 Shown; The shadow mask is a mature accessory in the manufacture of CRT color picture tubes. Using the shadow mask as a barrier in this way increases the yield of the entire screen and reduces the cost. Among them, the shadow mask is made of pure iron (AK steel). The unit structure is designed ...
