Abstract
A touch panel apparatus includes 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.
