Abstract
In a method for determining a contact of a display device according to an exemplary embodiment, a covariance matrix is used to extract a unique vector and a unique value and to obtain the main component through the unique vector and the unique value. The value of the main component is analyzed to determine the contact existence. The unique vector and the unique value are used to extract the main component, and then the contact existence is determined such that the touch existence and the position thereof may be correctly determined without errors.
