摘要：
A sensor structure of a touch panel and a method of determining a touch signal generated by the same are disclosed. The sensor structure includes a plurality of sensor lines disposed on a surface of a substrate, and a control circuit electrically connected to the sensor lines. Each of the sensor lines has a plurality of conductive pads and a conductive line electrically connected the conductive pads. The control circuit receives a touch signal from one of the sensor lines. The touch signal is resulting from a touch capacitance generated between a touch and one of the conductive pads of the sensor line. The control circuit calculates the position of the touch based on the touch capacitance. In addition, the touch capacitance generated by a conductive pad close to the control circuit is larger than the touch capacitance generated by another conductive pad further away from the control circuit.
