    • A touch detection method for capacitive touch panels includes the steps of scanning the rows and columns of the capacitive matrix of a touch panel respectively; obtaining the capacitance differential value; processing the obtained capacitance differential value; and determining whether there is a touch on the touch panel in response to the processed capacitance differential value. The capacitance differential value is obtained by one of the steps of synchronously scanning two rows at the same time; synchronously scanning two columns at the same time; scanning one row to obtain the capacitance differential value between the row and a reference capacitance; and scanning one column to obtain the capacitance differential value between the column and a reference capacitance. The present invention creates conditions for the elimination of common code interferences and greatly improves the interference resistance of a capacitive touch panel.
