Abstract
A force sensitive touch screen device can include a device body including a first region and a second region, a window on the device body and corresponding to the first and second regions, a display unit below the window corresponding to the first region, a key input unit on the second region, and a touch sensor including a first touch sensing layer, a second touch sensing layer, and a force sensing layer, in which the first and second touch sensing layers are between a polarizer layer and a thin film transistor (TFT) layer that can detect a position of a touch input by sensing a change of capacitance on the first sensing layer and the second sensing layer, the force sensing layer can detect a force of the touch input by sensing capacitance on the third sensing layer, and a finger scan sensor is installed in the key input unit.
