Seen from the above description, in the present embodiment, each the first electrode group only needs two pins of corresponding electrical connection, and each third electrode group also only needs two pins of corresponding electrical connection, therefore can further reduce pin number, the area that further reduces to bind district, further reduces costs.

It should be noted that, from aforementioned, in the second electrode group, each the second electrode can be oppositely arranged with the first electrode of three, four or five.In the time that each the second electrode is concrete and three the first electrodes are oppositely arranged, in the first electrode group, can each 3X+1 the first electrode be electrically connected by cabling, and be electrically connected to same pin, each 3X+2 the first electrode is electrically connected, and is electrically connected to same pin, each 3X+3 the first electrode is electrically connected, and be electrically connected to same pin, wherein X is nonnegative integer.Correspondingly, in the second electrode group, each the second electrode can be oppositely arranged with three, four or five s' third electrode.In the time that each the second electrode is concrete and three third electrodes are oppositely arranged, in third electrode group, can each 3Y+1 third electrode be electrically connected by cabling, and be electrically connected to same pin, each 3Y+2 third electrode is electrically connected, and is electrically connected to same pin, each 3Y+3 third electrode is electrically connected, and be electrically connected to same pin, wherein Y is nonnegative integer.

It should be noted that, each electrode (comprising each the first electrode, each the second electrode and each third electrode) and each cabling (comprising the first cabling 221, the second cabling 211, the 3rd cabling 212, the 4th cabling 231 and the 5th cabling 232) can adopt identical material and adopt identical technique to complete simultaneously, each electrode and each cabling also can be made respectively, and both materials also can be different.

In the touch control layer that the present embodiment provides, because touch control layer comprises multiple electrod-arrays, and each electrod-array utilizes a second electrode group and a first electrode group and a third electrode group to form respectively mutual capacitance, reach the effect that shares the second electrode group, the quantity that reduces pin, has reduced production cost and technology difficulty.Because the first different cablings 221 is drawn from first end and second end of electrod-array region respectively, part the first cabling 221 that is electrically connected the second electrode is drawn from the first end of electrod-array, part the first cabling 221 is drawn from the second end of electrod-array in addition, therefore, whole the first cablings 221 can not concentrated the space taking between the second electrode group and the first electrode group and third electrode group, insulating property between on the one hand can intensifier electrode, can reduce on the other hand the distance between the second electrode group and the first electrode group and third electrode group, therefore can be from the mutual capacitance between two aspect intensifier electrodes, improve the signal to noise ratio (S/N ratio) of touching signals, the final touch-control sensitivity that improves touch control layer.

In the touch control layer that the present embodiment provides, because the first different cablings 221 is drawn from first end and second end of electrod-array region respectively, not only the touch-control sensitivity of each electrod-array inside improves, and touch-control blind area between Different electrodes array reduces.

By specific experiment, in existing touch control layer, the distance between Different electrodes group is 0.45mm～0.60mm conventionally, and now in existing touch control layer, the mutual capacitance size between electrode is generally 0.050pF～0.065pF.And in the touch control layer that the present embodiment provides, when as shown in Figure 2, by two the first cablings 221 from described first end is drawn, distance between the first electrode group and the second electrode group (that is distance) between third electrode group and the second electrode group can be contracted to 0.30mm～0.40mm, and the cabling between electrode with electric conductivity reduces, therefore the mutual capacitance between the electrode being oppositely arranged can be increased to 0.070pF～0.090pF, and the touch-control sensitivity of touch control layer significantly improves.
