Problems solved by technology

[0005] The purpose of the present invention is to solve the problem of uneven adhesion of fluorescent powder caused by the influence of electromagnet or permanent magnet magnetic field on the slurry during the selective coating process of the three primary colors of the large-size working shadow mask of the shadow mask type PDP, and to provide a uniform distribution of the magnetic field intensity. Soft magnetic plate adsorption to quickly complete the alignment and bonding of the mask shadow mask and the working shadow mask, so as to completely eliminate the uneven adhesion of the phosphor paste caused by the influence of the magnetic field

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] Such as Figure 1-8 Shown:

[0031] A method for quickly completing the close fitting of a mask shadow mask and a working shadow mask, which mainly consists of the following steps:

[0032] a) Firstly, make a soft magnetic plate with uniform magnetic distribution and magnetic powder material evenly distributed in the plastic carrier;

[0033] b) Next, paste the entire soft magnetic board on the spraying frame, and perform post-processing after pasting, so that the surface flatness of the soft magnetic board is highly consistent;

[0034] c) Several sets of positioning holes are set on the corresponding positions of the alignment frame, working shadow mask and mask shadow mask frame, each set of positioning holes is composed of three alignment holes, and the distance between the three alignment holes is the same as that of the shadow mask net. ...

Abstract

The invention discloses a method which can rapidly finish the close joint of a mask aperture mask and a work aperture mask. The method uses a soft magnetic plate as a medium and finishes the whole spray process by processes of the pasting, the positioning, the clamping, the attaching, etc. The problem of the uniformity of phosphor spraying is solved fundamentally, and the method has the advantages of convenient operation, easy realization, high production yield and good consistency.

Description

technical field [0001] The invention relates to a production process of a shadow mask type plasma, in particular to a method for quickly completing the close fitting of a mask shadow mask and a working shadow mask. Background technique [0002] As is well known, a plasma display forms an image by discharging a specific gas and exciting a fluorescent material. That is, discharge is achieved by applying a predetermined voltage between two electrodes that are spatially close to each other and filled with gas. An image is formed by exciting a phosphor layer formed in a predetermined pattern by ultraviolet rays generated from a gas. [0003] The shadow mask plasma display uses the shadow mask commonly used in the production of color CRT (cathode ray tube) to replace the barrier ribs with complicated manufacturing process in the existing PDP (ie plasma display panel). Since the barrier ribs are replaced by a shadow mask, the process is simplified and the cost is reduced. [000...
