Problems solved by technology
After experimental verification, two main factors were found: one is the deformation during the rolling process, which causes the film to be uneven
The main reason for the deformation is that after the bus electrodes are added to the four sides of the flexible filter shielding film, the thickness of the surrounding area is greater than the thickness in the middle, and uneven force is generated during the rolling process, resulting in deformation
The second is that after the bus bars are pasted on the four sides, because the height of the four sides is increased, a cavity is formed in the middle, and the air bubbles are not easy to get rid of, resulting in residual air bubbles and causing unqualified
[0004] Both of these factors are caused by the increased thickness of the flexible filter shielding film after the bus electrodes are made around it.

Embodiment Construction
[0020] Below in conjunction with accompanying drawing, technical scheme of the present utility model is described in detail:
[0021] Such as figure 1 , figure 2 , image 3 as shown, figure 1 It is a structural schematic diagram of the bus electrode of the currently used flexible light filtering shielding film of the plasma display. The bus electrode is made around the flexible light-filtering shielding film; figure 2 It is a structural schematic diagram of the bus electrode of the flexible light filtering shielding film of the plasma display of the present invention, and the pasting process includes the following steps:
[0022] A. Paste the bus electrodes on the three sides of the screen in turn;
[0023] B. Paste the bus electrode on one side of the flexible light-filtering shielding film;
[0024] C. Paste the three sides of the flexible light-filtering shielding film that are not pasted with bus electrodes with the three sides of the screen body that are pasted wi...

The invention discloses a method of improving the yield of a flexible filtration screened film sticking conflux electrode, which changes the manufacturing of conflux electrode around film before. In the method, the conflux electrode (20) is separated into two parts to respectively manufacture on three sides of a plasma screen (30) and a flexible filtration screened film (10). The method can avoidthe phenomena of compressional deformation and bubble residual caused by that four sides of the flexible filtration screened film with omnibus bars are too thick, and improve yield of filtration filmsticking.
Description
technical field [0001] The invention relates to a method for improving the yield rate of a bus electrode pasted with a flexible light-filtering shielding film, in particular to a method for manufacturing a busbar electrode with a flexible light-filtering shielding film, specifically a method for improving the finished product pasted with a flexible light-filtering shielding film for a plasma display The production method of the high-rate bus electrode. Background technique [0002] At present, the method for preparing the flexible light-filtering shielding film of the plasma display is to make bus bars around the flexible light-filtering shielding film, and the material generally uses metal copper. The flexible filter film containing the bus bar is glued and bonded to the plasma screen on the film sticking equipment, and then fixed on the front panel with conductive rubber for grounding. [0003] The yield rate of the earlier LG-PDP film using the flexible film method has b...
