Claim:
1. A sensing method for a touch control apparatus, for sensing from a sensing electrode, the sensing electrode comprising a plurality of first sensing electrode units arranged in a first direction and a plurality of dummy lines arranged between the first sensing electrode units, the sensing method comprising: sensing with the first sensing electrode units; calculating a value in a sensed coordinate position corresponding to the first direction according to a sensed result of the first sensing electrode units; calculating a capacitance compensation value of a second direction according to the value of the first direction and a capacitance compensation function associated with a capacitance sensing value sensed by at least one of the dummy lines, wherein the second direction is perpendicular to the first direction; and calculating a value in the sensed coordinate position corresponding to the second direction according to the capacitance compensation value and a sensed result of the first sensing electrode units to obtain the sensed coordinate position.
