Embodiment 1

[0024] An embodiment of the present invention provides a screen printing screen.

[0025] The screen printing screen is used to print peelable glue on the surface of the display device, and the screen printing screen has a plurality of mesh holes;

[0026] The screen printing screen includes a central area 101 and an edge area 102 , and the colloid penetration of the screen printing screen in the edge area 102 is greater than that in the central area 101 .

[0027] In this embodiment, the screen printing plate has a plurality of mesh holes, and the peelable glue flows from the mesh holes to the surface of the display device, thereby printing the peelable glue on the surface of the display device to protect the surface of the display device. The screen printing screen comprises a central area 101 and an edge area 102, see figure 1 Screen printing screen shown. In the prior art, the thickness of the peelable adhesive in the edge region 102 is smaller than that in the central r...

Embodiment 2

[0030] An embodiment of the present invention provides a screen printing screen.

[0031] The opening ratio of the screen printing screen in the edge area 102 is greater than the opening ratio in the central area 101 .

[0032] In this embodiment, the greater the opening ratio, the greater the amount of colloid permeation, and the thicker the thickness of the printed peelable adhesive. The opening ratio of the screen printing screen in the edge area 102 is greater than that in the central area 101 , so that the thickness of the peelable adhesive in the edge area 102 is not less than the thickness of the central area 101 . Specifically, the opening ratio is a percentage of the first area to the second area, the first area is the square of the opening width, and the second area is the square of the sum of the opening width and the wire diameter. refer to image 3 In the mesh of the screen printing screen shown, the first area 103 is the square of the opening width A, C is the ...

Abstract

The invention provides a silk screen board. The silk screen board is used for printing peelable glue on the surface of a display device, wherein a plurality of mesh openings are formed in the silk screen board; the silk screen board comprises a central area and an edge area; the glue permeation rate of the silk screen board in the edge area is greater than that of the silk screen board in the central area, so that the thickness of the peelable glue in the edge area is increased. When the peelable glue is torn off, residue caused by breakage of the peelable glue can be avoided even if tearing stress is relatively great, as the thickness of the peelable glue in the edge area is relatively great, and further subsequent detection difficulty and cleaning cost are reduced.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a screen printing screen. Background technique [0002] At present, after the production process of TSP (touch screen panel mainly refers to the panel of the touch screen) and electronic paper products is completed, in the subsequent cutting and transportation, the products need to be protected to prevent moisture, static electricity and scratches from causing damage to the products. bad. In the prior art, a screen printing screen is used to print peelable glue, which is covered on the surface of the product for protection. [0003] The peelable adhesive is coated on the glass cover where a single panel needs to be covered. Due to the fluidity of the gel, etc., the peelable adhesive is thinner at the edge of the covered area. When the peelable glue is torn off, since the edge area of ​​each piece of peelable glue is thinner than the central area, the force on the edge ar...
