The invention is not restricted to this.As shown in figure 3, the central point of touch objects is by P1, and D1 straight lines are moved along a first direction
Move to P2.When the central point of touch objects is located at P1, touch objects are big with the overlapping area of second electrode 110
In touch objects and the overlapping area of first electrode 108.Therefore, when the central point of touch objects is located at P1, touch
Control panel 100 detected by position P1 ' relative to touch objects center point P 1 along second direction D2 court
Top offset.When the central point of touch objects is located at P2, the overlapping area of touch objects and second electrode 110 is then
It is less than the overlapping area of touch objects and first electrode 108, therefore the position detected by contact panel 100
About slightly P2 ', its relative to touch objects center point P 2 along second direction D2 towards bottom offset.So
One, the motion track of touch objects detected by contact panel 100 and do not meet touch objects reality movement
