Touch screen system having active area setting function and control method thereof

The set of active area touch screen system and a control method are disclosed. A touch screen system according to the present invention, a touch on the basis of the detection signal at least to the display unit one of the working window to be displayed, in response to a touch input on the display portion to be output from the touch panel and a touch panel which outputs a predetermined detection signal coordinates calculation portion, and at least one of the coordinate value information indicating the active region for the task pane, the active operation of the window is stored in the coordinate value storing unit and the calculated coordinate values ​​to calculate the coordinate value of the location corresponding to the input when the coordinate determination unit and the determination unit determined that the value represented by the coordinate information stored in the storage unit to determine whether or not present in the active region, the calculated coordinate values ​​are present in the outside of the active region position, a response corresponding to the touch input to a control unit for blocking. This makes it possible to reduce the error in the input it is possible to prevent the operation is delayed.
