Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
The embodiment of the invention provides a silk-screen printing plate.
The screen printing plate is used for printing peelable glue on the surface of the display device and is provided with a plurality of meshes;
the silk-screen printing plate comprises a central area 101 and an edge area 102, and the colloid permeability of the silk-screen printing plate in the edge area 102 is greater than that in the central area 101.
In this embodiment, the screen plate has a plurality of meshes, and the peelable glue flows from the meshes to the surface of the display device, so that the peelable glue is printed on the surface of the display device to protect the surface of the display device. The screen comprises a central region 101 and an edge region 102, see the screen shown in fig. 1. In the prior art, the thickness of the peelable glue in the edge region 102 is smaller than that in the central region 101, see the thickness of the peelable glue shown in fig. 2a, so that when the peelable glue is peeled off, the peelable glue in the edge region is stressed more than that in the central region in a cross section per unit area, and the peelable glue in the edge region is more easily broken, so that the peelable glue remains. In the embodiment of the present invention, the colloid transmittance of the screen printing plate in the edge region 102 is greater than the colloid transmittance in the central region 101, so that the thickness of the peelable glue in the edge region 102 is thicker, which is the same as or greater than the thickness of the central region 101, as shown in fig. 2 b. Because the thickness of the peelable glue of the edge region 102 is not less than that of the center region 101, when the peelable glue is torn off, the stress of the peelable glue of the edge region 102 is not greater than that of the peelable glue of the center region 101 on the cross section of a unit area, so that the problems that the peelable glue of the edge region is easy to break and remain are solved.
In summary, in the embodiment of the present invention, the screen printing plate includes the central area and the edge area, and the colloid permeability of the screen printing plate in the edge area is greater than that in the central area, so as to increase the thickness of the peelable glue in the edge area. When tearing off the peelable glue, because the peelable glue is thicker in the marginal area, even tear off and make the atress great, also can avoid the peelable glue fracture and cause and remain to reduce the degree of difficulty and the abluent cost of follow-up detection.
Example two
The embodiment of the invention provides a silk-screen printing plate.
The opening ratio of the silk screen printing plate in the edge area 102 is greater than that of the central area 101.
In this embodiment, the larger the aperture ratio, the more the colloid permeability, and the thicker the thickness of the printed peelable glue. The opening ratio of the screen printing plate in the edge area 102 is greater than that of the central area 101, so that the thickness of the peelable glue in the edge area 102 is not less than that of the central area 101. Specifically, the aperture ratio is a percentage of a first area in a second area, the first area is a square of an aperture width, and the second area is a square of a sum of the aperture width and a line diameter. Referring to the mesh of the screen printing plate shown in fig. 3, the first area 103 is the square of the opening width a, C is the sum of the opening width a and the line diameter B, and the second area 104 is the square of the sum of the opening width a and the line diameter B, i.e., the second area is the square of C. The aperture ratio is a percentage of the first area 1 to the second area 2, i.e., the aperture ratio (first area 103/second area 104) × 100 ═ a2/C2)×100％＝A2/(A+B)2×100％。
Preferably, the wire diameter of the silk-screen plate in the edge region 102 is smaller than that in the central region 101.
In this embodiment, the aperture ratio is affected by the aperture width a and the line diameter B, the line diameter of the silk-screen printing plate in the edge area 102 is smaller than the line diameter in the central area 101, and according to the calculation formula of the aperture ratio, the aperture ratio of the silk-screen printing plate in the edge area 102 is greater than the aperture ratio in the central area 101, as shown in fig. 4. The screen printing plate has a larger opening ratio in the edge region 102, so that the thickness of the peelable glue in the edge region 102 is not less than that in the central region 101.
In a preferred embodiment of the present invention, the mesh number of the silk-screen printing plate in the edge region 102 is greater than that in the central region 101.
In this embodiment, the mesh number of the silk-screen plate is the number of meshes, and the mesh number of the silk-screen plate in the edge region 102 is greater than the mesh number in the central region 101, that is, the mesh number of the silk-screen plate in the edge region 102 is greater than the mesh number in the central region 101, as shown in fig. 5. The screen printing plate has a greater number of voids in the edge region 102, so that the thickness of the peelable glue in the edge region 102 is not less than the thickness in the central region 101.
In a preferred embodiment of the present invention, a colloid flow velocity of the silk-screen printing plate in the edge region 102 is greater than a colloid flow velocity of the central region 101. Specifically, the greater the gel flow rate and the greater the gel throughput, the greater the thickness of the printed peelable gel. The glue flow rate of the edge area 102 is greater than the glue flow rate of the central area 101, so that the thickness of the peelable glue of the edge area 102 is not less than the thickness of the peelable glue of the central area 101.
Preferably, the thickness of the screen printing plate in the edge region 102 is smaller than the thickness in the central region 101.
In this embodiment, the thickness of the screen in the edge region 102 is smaller than the thickness in the central region 101, see the screen shown in fig. 6. And coating the peelable glue on the surface of the silk-screen printing plate, wherein the peelable glue flows down from the meshes 105 and is distributed on the surface of the glass cover plate. Since the thickness of the screen printing plate in the edge region 102 is smaller than the thickness of the screen printing plate in the central region 101, the colloid flow rate of the screen printing plate in the edge region 102 is greater than the colloid flow rate in the central region 101, and the thickness of the peelable glue in the edge region 102 is not less than the thickness of the peelable glue in the central region 101. In fig. 6, the photo-curable emulsion 106 is applied to the area of the screen printing plate, the peelable glue cannot flow down to the surface of the glass cover plate through the mesh 105, and in the area where the photo-curable emulsion 106 is not applied, the peelable glue can flow down to the surface of the glass cover plate through the mesh 105.
In this embodiment, the silk screen may be made of various materials, and preferably, the silk screen includes a composite steel wire mesh. The embodiment of the present invention is not limited in detail, and may be selected according to actual situations.
In summary, in the embodiments of the present invention, the opening ratio and the mesh number of the screen printing plate are increased, or the thickness of the screen printing plate is reduced, so that the colloid permeability of the screen printing plate in the edge region is increased, and the peelable glue is thickened in the edge region. When the peelable glue is torn off, the peelable glue is thicker in the edge area, so that even if the peelable glue is torn off to cause larger stress, the peelable glue can be prevented from being broken to cause residue, and the difficulty of subsequent detection and the cost of cleaning are reduced. .
