Mobile terminal and method for controlling the same

A force sensitive touch screen device comprising:

• a device body including a first region and a second region;
• a window mounted on the device body and corresponding to the first region and the second region;
• a display unit disposed below the window corresponding to the first region;
• a key input unit disposed on the second region;
• and
• a touch sensor comprising a first touch sensing layer, a second touch sensing layer, and a force sensing layer,
• wherein the first touch sensing layer and the second touch sensing layer are disposed between a polarizer layer and a thin film transistor (TFT) layer configured to detect a position of a touch input by sensing a change of capacitance on the first sensing layer and the second sensing layer,
• wherein an insulating layer is disposed between the first sensing layer and the second sensing layer,
• wherein the force sensing layer is configured detect a force of the touch input by sensing a change of capacitance on the third sensing layer, and
• wherein the key input unit is a mechanical key and a finger scan sensor is installed in the key input unit.
