1. A signal measuring method for a touch screen comprising:

  • determining a delay phase difference for each one or each set of a plurality of driving electrodes of a touch screen comprising a plurality of detecting electrodes, wherein the delay phase difference is a phase difference between a mutual capacitive coupling signal outputted from each one of the plurality of detecting electrodes and a driving signal inputted to said each one or each set of the plurality of driving electrodes; and

    delaying a mutual capacitive coupling detection of all of the plurality of detecting electrodes for the delay phase difference when the driving signal is inputted to said each one or each set of the plurality of driving electrodes.
