1. A dual-differential sensing method, comprising:

  • obtaining a 2-D sensing information; and

    determining whether there is at least one touch related sensing information in the 2-D sensing information, wherein the 2-D sensing information comprises a plurality of 1-D sensing information, and each 1-D sensing information comprises a plurality of dual difference values, wherein a dual difference value of each 1-D sensing information is determined by the operations;

    receiving a first signal value from a first sensor;

    receiving a second signal value from a second sensor; and

    receiving a third signal value from a third sensor;

    generating the dual difference value by subtracting twice of said second signal value from the sum of said first signal value and said third signal value or subtracting the sum of said first signal value and said third signal value from twice of said second signal value.
