Touch panel apparatus and method for controlling the same

A touch panel apparatus, comprising:

• a touch panel for recognizing a contact position;
• and
• a touch panel controller for computing a coordinate value corresponding to the contact position on the touch panel,
• wherein an activation force is set to a value between 80 g-150 g, and the touch panel controller compensates for an error of the coordinate value due to double touching of the touch panel,
• wherein the touch panel controller computes a first coordinate value for a first touch generated in the touch panel, and
• the touch panel controller computes a second coordinate value corresponding to a second touch and determines whether there is an error in the second coordinate value due to a double touching by comparing the second coordinate value to a preset reference coordinate value when an input signal corresponding to the second touch is received within a predefined time period.
