1. A touch panel having a multi-touch function, comprising:

  • a transparent conductive substrate;

    a transparent conductive film disposed on the transparent conductive substrate;

    two first conducting wires disposed at two sides of the transparent conductive substrate, respectively to provide a constant voltage;

    two second conducting wires disposed at two sides of the transparent conductive film, respectively, wherein the second conducting wires are vertical to the first conducting wires and used to provide the constant voltage, and when the transparent conductive film is touched, a dividing voltage is generated; and

    a main detecting module obtaining a touch resistance value according to the constant voltage and the dividing voltage, comparing the touch resistance value with a preset resistance value and determining that a multi-touch mode is executed when the touch resistance value is less than the preset resistance value.
