1. A detection method for detecting a plurality of contacts on a touch panel, the touch panel comprising a plurality of first sensing axes on a first dimension and a plurality of second sensing axes on a second dimension, the detection method comprising:

  • generating a preliminary sensing data according to the contacts on the touch panel;

    determining at least one specific sensing axis included in the plurality of first sensing axes according to the preliminary sensing data;

    utilizing a configuration circuit to configure a driving and receiving sequence of the plurality of first sensing axes and the plurality of second sensing axes for obtaining a sensing output, comprising;

    utilizing a driving circuit to drive the at least one specific sensing axis one-by-one;

    respectively receive a sensing data corresponding to the at least one specific sensing axis from the plurality of second sensing axes of the touch panel through a multiplexer, and accordingly obtaining a sensing output; and

    storing the sensing output in a storage element; and

    utilizing a determining circuit to receive a completion instruction, wherein when the determining circuit receives the completion instruction, the determining circuit determines a touch detection result according to the sensing output.
