It is described in detail below in conjunction with specific implementation of the specific embodiment to the present invention：
The embodiment of the present invention provides a kind of capacitive touch screen, similar with conventional touch screen, and it includes LCD and shows mould
Group and touch module, improvements essentially consist in wire structures, are changed by the structure of all or part of wire to wiring
Enter, solve the problems, such as static discharge.Specifically, the wire structures of the capacitive touch screen are as shown in Figure 2, it should be noted that
Local wiring structure is only shown, overall routing is to be formed with the partial structurtes to both direction limited extension in length and breadth in Fig. 2.The cloth
Line includes two groups of wires intersected in length and breadth, i.e., a plurality of first electrode wire 1 and a plurality of second electrode wire 2.First electrode wire 1
Include several wire blocks 3 continuously to connect with second electrode wire 2, the wire block 3 includes a ring shaped conductive block 31, also wrapped
The built-in block 33 being arranged inside ring shaped conductive block 31 is included, several tips 32 are extended in the inner side of the ring shaped conductive block 31, interior
Extend several tips 34 in the outside for putting block 33, naturally it is also possible to only in the inner side of ring shaped conductive block 31 or built-in block 33
Extend several tips in outside.For convenience of description, the tip 32 inner side of ring shaped conductive block 31 extended is referred to as first
Tip, the tip 34 that the outside of built-in block 33 is extended are referred to as the second tip.
The present embodiment is by the point discharge effect of the first tip and the second tip by electrostatic caused by high electric field from passage
Internal consumption is fallen, and without influenceing other passages and circuit mechanism, improves the reliability of touch-screen, and improve product yield.
Such as Fig. 2 and Fig. 3, the first tip 32 and the second tip 34 can be one by one in pairs and sophisticated relative, and can also interlock phase
To distribution, such as Fig. 4.The present embodiment is more preferably the arrangement mode that tip is relative shown in Fig. 3, is easy to be molded.
In the present embodiment, the built-in block 33 can be bulk-solid items structure, can also be hollow annular construction, for example,
Ring shaped conductive block 31 and built-in block 33 shown in Fig. 5 are with one heart three-back-shaped.
Further, the shape of the ring shaped conductive block 31 and built-in block 33 is not limited to rectangle shown in the drawings or square knot
