The disadvantage is that the voltage applied to the touch panel is switched on and off, which is easy to cause interference; and the circuit on the layout is one. The linearity between the next layer is poor. One ° Bay' will cause (3) The five-green type is formed by four X-axis Υ axes for the lower electrode, and is controlled by the other wiring. Therefore, the upper electrode has a higher resistance value and the electrode is bad. The shortcoming is that the touch panel has only one driving mode, and the car is not easy to damage the road and only one line. Once the line is damaged, the line cannot be operated and the detection line is the most common wiring type. Each of the four X-axis γ axes of the lower electrode is formed. The shortcomings A, the upper part of the crucible and the applied voltage are switched between the upper and lower layers, and it is easy to cause the circuit of the touch panel to be cut but the linearity is poor. The present invention is directed to the above-mentioned problem of avoiding the absence of the above-mentioned problems. The space 'is not constrained by the single-drive mode. In addition, it has a multi-cardioid type, which can increase the selectivity of the detection line, and can avoid the situation that the line cannot be used because of the one or one bay 7; the single lower layer or the upper substrate 5 Two $3 damage can be used to enhance the use of four-wire and eight-wire touch panels. In order to achieve the above purpose, the present invention proposes a structure in which the upper substrate and the lower substrate having the X-axis and the γ-axis are arranged and the induced voltage is applied to the panel substrate, so that the Two electric powers: the position of the resistor becomes the value of the quadratic coordinate value, and the contact is characterized in that among the four sides of the upper substrate and the lower substrate, in the control panel, the middle position respectively pulls out the pin
