Abstract
A touch sensing device includes a touch coordinate calculation unit configured to calculate touch coordinates for touch inputs that occurred on a touch screen panel, a reference coordinate setting unit configured to set one reference coordinate for each predetermined sample section on the basis of positions at which the touch coordinates are generated, and a touch coordinate correction unit configured to generate touch output-coordinates for the touch coordinates by smoothing each of touch coordinates positioned in a corresponding sample section on the basis of the reference coordinate set for the corresponding sample section.
