Abstract:
1. A touch screen system, comprising, a display unit for displaying at least one of a plurality of interfaces; a touch panel for outputting a signal in correspondence with a touch input on the display unit; a coordinate value calculation unit for calculating first coordinate values of the touch input based on the signal outputted from the touch panel; a coordinate value storage unit for storing coordinate value information indicating an active region; a decision unit for deciding whether the first coordinate values exist in the active region indicated by the coordinate value information stored in the coordinate value storage unit, in a decision; a control unit for interrupting a response to the touch input if the first coordinate values exist outside the active region according to the decision of the decision unit; and a mode selection unit for setting an active area, and wherein the active region comprises a region having coordinate values of four edges of an active interface of the plurality of the interfaces, and a region having coordinate values of four edges of a status bar, wherein the mode selection unit sets an operation mode of the touch panel to one of a first mode for setting an entire area of the display unit as the active area, a second mode for setting the entire area of the display unit to an inactive area, and a third mode for setting a certain region of the display unit to the active area.
