Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Such as image 3 shown.
[0021] A method for eliminating residual fluorescent powder on the small hole surface during the shadow mask coating process, comprising the following steps:
[0022] Firstly, align the working shadow mask with the mask shadow mask;
[0023] Secondly, make the working shadow mask and the rubber soft magnetic plate stick together tightly, and add at least one piece of copper paper that matches the size of the working shadow mask between the working shadow mask and the rubber soft magnetic plate to eliminate excess phosphor during the spraying process particles, such as image 3 shown;
[0024] Finally, start to open the spraying walking mechanism, first walk a distance to see if it can run normally, and if it is normal, return to the origin to prepare for spraying. Then turn on the switch button of the spray gun, adj...

A method for eliminating residual fluorescent powder on the small hole surface during the coating process of a shadow mask, which belongs to the manufacturing method of a shadow mask type flat-panel television, and includes the following steps: first, aligning and fitting the working shadow mask and the mask shadow mask; secondly , so that the working shadow mask and the rubber soft magnetic plate are tightly attached; finally, the spraying operation is carried out; it is characterized in that at least one piece of copper paper matching the size of the working shadow mask is added between the working shadow mask and the rubber soft magnetic plate to eliminate Excess phosphor particles from the spraying process. The method of the invention can solve the excess powder generated on the small hole surface of the shadow mask during the spraying process only by simple treatment and adjustment, and has the advantages of low cost, convenient operation and the like.
Description
technical field [0001] The invention relates to a manufacturing process of a shadow mask type plasma display, in particular to a method for spraying phosphor powder on a shadow mask of a shadow mask type plasma display, in particular to a method for eliminating the working shadow mask during the shadow mask coating process. The method of remaining fluorescent powder on the small hole surface. Background technique [0002] In recent years, among color display devices using image display such as computers and televisions, display devices using plasma display panels (hereinafter abbreviated as PDPs) have attracted attention as color display devices that can achieve thinner and lighter weight while being enlarged. Attention. [0003] The PDP displays colors by additively mixing the so-called three primary colors (red, green, and blue). In order to perform full-color display, phosphor layers capable of emitting three primary colors of red (R), green (G) and blue (B) light are i...
