Claim:
1. A touch pattern structure of an in-cell capacitive touch screen, comprising: a plurality of driving lines in a first direction, wherein the plurality of driving lines is disposed in a first layer and insulated from each other; a plurality of sensing lines in a second direction, wherein the plurality of sensing lines is disposed in the first layer and insulated from each other, wherein the plurality of sensing lines intersects the plurality of driving lines; an insulating layer displaced on the first layer; and a plurality of conductive bridges disposed on the insulating layer, each having two ends connecting two of the plurality of sensing lines at intercepting locations, wherein the plurality of conductive bridges is insulated from the driving lines; wherein the touch pattern structure is integrated in a display panel of the in-cell capacitive touch screen; wherein each driving electrode and each sensing electrode comprise teeth at least on one side, wherein the teeth of the driving electrodes interweave with the teeth of an opposing sensing electrode to form an intertwined structure; wherein a pair of the interwoven teeth defines a repeating unit; and wherein in a case each tooth is rectangular and the sensing electrode excluding the teeth is rectangular, a number of the teeth in the sensing electrode is greater than a value of L*(Y−2A)/A*B, where Y is a width of the rectangular-shaped sensing electrode body, A is a width and B is a depth of the rectangular-shaped tooth and L is a length of a long side, of one of the plurality of driving electrodes.
