    • A touch sensing device employing a new sensing method of the present invention is composed of the sensing portion which senses capacitance change of the touch sensing electrodes forming the touch panel, plurality of capacitance compensating capacitors which are used in common for the sensing electrodes in order to compensate fluctuation of touch sensing electrodes of the touch panel, and the ROM which is storing the data for selecting the capacitance compensating capacitors. The ON-OFF output voltage levels in the touch/non-touch conditions to the touch sensing electrodes can be equalized for each electrode and thereby the touch sensing with high accuracy can be realized by selecting the capacitance compensating capacitor by means of the ROM at the time of retrieving each touch sensing electrode.
