10. a kind of capacitance type touch control screen wire laying mode, said touch screen has substrate and touch-control circuit, and substrate is provided with and is no less than two groups of touch-control electrode wires groups that capable touch-control electrode wires of m bar and n bar row touch-control electrode wires are arranged respectively, and wherein m and n are the natural numbers greater than 2; The electrode wires mutually insulated intersects between two groups of ranks, on the same group in each strip electrode line mutually disjoint, each bar touch-control electrode wires has exit, extension line and leading foot in the group; The exit of said touch-control electrode wires is meant that the touch-control electrode wires extends outside the touch area the borderline end points in the touch area from the touch area; The extension line of said touch-control electrode wires is meant that touch-control electrode wires exit extends electrode wires to the touch area outside, the connection touch-control circuit from the border, touch area; The leading foot of said touch-control electrode wires is meant the position that is connected with outside touch-control circuit on the extension line of touch-control electrode wires, and said external circuit comprises flexible PCB; Said touch area is meant the zone that can carry out touch control operation on the substrate; Said touch-control circuit has touch-control driving source and touching signals testing circuit; Each bar touch-control electrode wires of two groups of touch-control electrode wires connects touch-control circuit; In the period of touch-control circuit work; The touch-control driving source is applied with the touch-control pumping signal simultaneously to each the strip electrode line in two groups of touch-control electrode wires; Whether touching signals testing circuit while or timesharing detect the touching signals on each electrode wires, survey each electrode wires and touched; Said touch-control circuit is touch-control IC; It is characterized in that:

Said capacitance type touch control screen, touch-control IC are directly to be placed on the substrate of capacitance type touch control screen, and the leading foot of touch-control electrode wires is connected on the pin of touch-control IC and the substrate, also is provided with the flexible PCB that is connected with external circuit on the substrate of touch screen; Exit electrode and flexible PCB top electrode on touch-control electrode wires leading foot and the substrate on touch-control IC pin and the substrate all are to be connected through different side's conducting film.

11. capacitance type touch control screen wire laying mode according to claim 10 is characterized in that:

Interior on the same group touch-control electrode wires has single-ended exit on the said touch screen substrate; Adjacent touch-control electrode wires exit is arranged on the different directions of touch-control electrode wires, on the same group in adjacent touch-control electrode wires be connected to from different directions on the pin of the relative both sides of touch-control IC through exit, extension line and leading foot.

12. capacitance type touch control screen wire laying mode according to claim 10 is characterized in that:

Have the touch-control electrode wires of both-end leading foot on the said touch screen substrate on the same group, the leading foot of its both-end is connected on the pin of the relative both sides of touch-control IC from different directions.

13. capacitance type touch control screen wire laying mode according to claim 10 is characterized in that:

The relevant position preparation that has exit on the said touch screen substrate has conductive shielding layer; Said screen layer and touch-control IC be stratified and set on same substrate and be on the different layers on the same surface of substrate with the touch-control electrode wires group on the substrate, the scope of screen layer covers the leading foot of touch-control IC and touch-control electrode wires as far as possible.
