Anti-static structure of touch screen

Abstract

The invention discloses an anti-static structure of a touch screen, which comprises a protective cover plate. The bottom of the protective cover plate is fixedly connected with an upper anti-static matching plate. A grounding groove is etched in the part, in contact with the protective cover plate, of the upper anti-static matching plate. A cathode conducting layer, an isolation layer and an anodeconducting layer are sequentially connected into the groove of the upper anti-static matching plate from top to bottom, and a liquid crystal display layer is connected to the bottom of the lower anti-static matching plate. Conductive adhesives are coated in the grounding grooves of the upper anti-static matching plate and the lower anti-static matching plate; a plurality of grounding wire slots are uniformly formed in the edges of the upper anti-static matching plate and the lower anti-static matching plate; according to the invention, the anti-static matching plates are arranged above the cathode conducting layer and below the anode conducting layer. The two-way electrostatic breakdown phenomenon is effectively prevented. The thickness of the electrostatic layer is reduced through the grounding groove type design. Meanwhile, the upper anti-static matching plate and the lower anti-static matching plate protect the conductive layer while static electricity is effectively guided out. The functions are diversified.

Problems solved by technology

[0003] But the above-mentioned anti-static capacitive touch screen for mobile phones still has obvious defects during use: 1. The above-mentioned anti-static capacitive touch screen is only provided with an anti-static layer below the visible area, and this anti-static layer is only used for Prevent the electrostatic breakdown generated by fingers into the touch screen, and the anti-static layer increases the overall thickness of the touch screen; 2. The above-mentioned device does not protect other conductive functional layers, and its functions are relatively limited
