Abstract: A method for acquiring capacitance of a capacitive touch panel includes acquiring a selected capacitance value at a selected point among a plurality of points at which a plurality of capacitances are present, in the capacitive touch panel, determining the selected capacitance value as a reference capacitance value, and performing a multi-driving using a balanced code, and acquiring a capacitance value from at least one point among the plurality of points using the reference capacitance value.
