Abstract
A touch screen including a display unit on which a pointer is displayed and a touch-sensing unit mounted on the display unit to generate a display position signal of the pointer when brought into contact with a separate contact medium. The display unit changes the display position of the pointer in accordance with the drag direction of the contact medium when the contact medium, which stays in contact with the touch-sensing unit, is dragged. Accordingly, the pointer being displayed is movable, and the moving speed and migration length of the pointer can be adjusted according to the selection of a user to achieve improved convenience in use. The touch screen may simplify structure and achieve aesthetic enhancement by eliminating the necessity of a touch pad for moving the pointer.

18. A touch screen comprising:
-
a display unit on which a pointer is displayed at a display position; and a touch-sensing unit mounted on the display unit to generate a display position signal of the pointer when a separate contact medium is brought into contact with the touch-sensing unit, wherein the display unit is configured to change the display position of the pointer in accordance with a direction in which the contact medium is dragged when the contact medium, which remains in contact with the touch-sensing unit, is dragged a drag distance. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. A touch screen comprising:
-
a display unit on which a pointer is displayed at a position; and a touch-sensing unit mounted on the display unit to generate a display position signal of the pointer when a separate contact medium is brought into contact with the touch-sensing unit, wherein the display unit is configured to change the display position of the pointer (300) in a direction from a reference point set on the touch-sensing unit towards a contact point of the touch-sensing unit in which the contact medium is in contact. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)

34. A touch screen comprising:
-
a display unit on which a pointer is displayed; a touch-sensing unit mounted on the display unit to generate a display position signal of the pointer when a separate contact medium is brought into contact with the touch-sensing unit; and a pressure sensor for sensing a contact pressure of the contact medium applied to the touch-sensing unit, wherein when the contact pressure is applied at an angle so as to have a vertical pressure component and a horizontal pressure component, the display unit is configured to increase or decrease a displacement distance of the display position of the pointer by displacing the display position of the pointer in a direction of the horizontal pressure component and applying a weighted value to a magnitude of the vertical pressure component.
