Abstract
A touch panel includes a substrate, a touch-sensing circuit, a plurality of sensing signal transmission wires, a capacitance compensation conductor, and a sensing signal readout circuit. The touch-sensing circuit is disposed on the substrate. The sensing signal transmission wires are disposed on the substrate and electrically connected to the touch-sensing circuit. The capacitance compensation conductor is disposed over the sensing signal transmission wires. Capacitance of each sensing signal transmission wire is C, and coupling capacitance between each sensing signal transmission wire and the capacitance compensation conductor is C. The sensing signal readout circuit is electrically connected to the sensing signal transmission wires. In each sensing signal transmission wire, variation of summation of Cand Cis less than a readout resolution of the sensing signal readout circuit. Another touch panel using an electrostatic discharge conductor to adjust varied capacitances of sensing signal transmission wires is also provided.
