Abstract: A touch panel metal grid structure with augmented mutual capacitance includes a substrate, a driver layer, a detection layer, and a capacitance detection device. The driver layer is disposed on the substrate. The driver layer includes a plurality of circular patterns and each two said circular patterns are connected together by using a bridge wire. The detection layer is disposed on the substrate. The detection layer includes a plurality of polarized quadrilateral patterns. Each of the polarized quadrilateral patterns is disposed correspondingly to each of the circular patterns to form a touch-sensing pattern. The capacitance detection device is electrically connected to the detection layer and the driver layer. Therefore, the present invention can enhance touch control signals and can effectively prevent a cathode and other electric fields from interfering in the signals.
