Embodiment Construction

[0017] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. Detailed instructions:

[0018] as attached figure 1 , attached figure 2 As shown, the present invention is a capacitive touch screen. The capacitive touch screen includes a glass layer 1, a BM layer 2, a metal grid layer 3, and an OC layer 4. The BM layer 2 is located outside the glass layer 1. The metal grid layer 3 is located outside the BM layer 2, and the OC layer 4 is located outside the metal grid layer 3. The line width of the metal wires of the metal grid layer 3 is controlled within the range of 3um-5um, and the metal grid layer The layer 3 includes a blank area 5 and a metal area 6, the blank area 5 accounts for more than 80% of ...

Abstract

The invention provides a capacitive touch screen applied to the technical field of touch screens. A BM layer (2) of the capacitive touch screen is located on the outer side of a glass layer (1); a metal mesh layer (3) is located on the outer side of the BM layer (2); an OC layer (4) is located on the outer side of the metal mesh layer (3); the line width of a metal wire of the metal mesh layer (3)is controlled within a range of 3 microns to 5 microns; the metal mesh layer (3) comprises a blank area (5) and a metal area (6); the blank area (5) accounts for the area of the metal mesh layer (3)by more than 80%; and the mesh shape of the metal mesh layer (3) adopts a rhombic structure. The capacitive touch screen is simple in structure; the manufacturing process of the touch screen can be effectively shortened; the manufacturing cost is reduced; the manufacturing efficiency is improved; the resistance value of the touch screen is reduced; the conductivity is better; the touch control ismore sensitive; and the touch control is more accurate.

Description

technical field [0001] The invention belongs to the technical field of touch screens, and more specifically relates to a capacitive touch screen. Background technique [0002] As the touch screen OGS technology becomes mature and stable, it can no longer fully meet the market demand, and will be relatively positioned in the middle and low-end medium and large size capacitive touch screen market. The touch screen in the prior art has a high resistance value of the ITO layer, poor conductivity, and poor operation accuracy, so that it cannot effectively adapt to market demand, resulting in poor competitiveness. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a simple structure, which can effectively shorten the production process of the touch screen, reduce the production cost, improve the production efficiency, reduce the resistance value of the touch screen, and have better conductivity. Capacitive touch screen w...
