摘要:
A static capacitance type touch panel, a control unit electrically connected with X and Y electrodes for detecting a touch position based on a measured value of a static capacitance between the X and Y electrodes. The control unit includes a predetermined touch threshold for detecting a peak, a near-peak range and a non-near-peak range, a first parameter for determining a value of the near peak range, and a second parameter for determining a value of the non-near-peak range. The first and second parameters are respectively predetermined for reduction of a noise influence from the measured value of the static capacitance between the X electrode and the Y electrode.
