Embodiment Construction

[0040] Embodiments of the cleaning method and device for a model printing mask of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] 4a and 4b are explanatory views of the cleaning method of the screen mask in the present invention.

[0042] First, if the electrode paint or the intermediate paint is coated at least once on the substrate, as shown in FIG. 34 back. In order to remove these foreign objects 38, the first cleaning roller 40 wound with the first cleaning tape 42, as shown in FIG. remove. At the same time, due to the pressure of the first cleaning roller 40, the foreign matter adhering to the back and side surfaces of the screen cover is removed by the second cleaning roller 50 wound with the second cleaning tape 52.

[0043] Replace the 2nd cleaning roller 50 that is wound with the 2nd cleaning tape 52 as shown in Figure 5, utilize the supporting material 46 to exert the same pressure on the front of the ...

Abstract

It relates to the cleaning method for the printing mask of moulds for printing with at least one thin film coatings on the plasma display, with back and front of the mask contacting with the cleaning part, eliminating impurities on the mask. It adds the mask's durability with improved cleanliness.

Description

technical field [0001] The present invention relates to a method and a device for cleaning a mask used for model printing of a plasma display, in particular to a method for cleaning a screen mask and increasing the service life of the screen mask while improving the cleanliness of the screen mask. its device. Background technique [0002] Plasma display (Plasma Display Panel: hereinafter referred to as "PDP") is a display device that makes phosphors emit light when ultraviolet rays generated by gas discharge cause phosphors to undergo catastrophic changes. Compared with the cathode tube (Cathode Ray Tube: CRT), which is the ancestor of the current display device, the PDP has the advantages of being thinner, lighter in weight, bright in color, and larger in screen size. A PDP is composed of a plurality of discharge elements arranged in a model form. One discharge element forms one pixel of the screen. [0003] The discharge element of the existing 3-electrode AC surface di...
