1. A touch screen responsive to a touch action and arranged in a housing having a bottom surface, wherein the touch screen comprises:
- a display for displaying through a front surface of the display, wherein the display is mounted inside the housing and further comprises a back surface being offset by a gap from the bottom surface of the housing in a direction perpendicular to the bottom surface;
a sensor system being interposed between the back surface and the bottom surface, the sensor system comprising;
a first electrode assembly comprising at least one electrode, anda second electrode assembly comprising at least one electrode, the sensor system being configured to sense a capacitance between the first electrode assembly and the second electrode assembly; and
a processor, the processor being configured to determine, based on the sensed capacitance, a force resulting from the touch action.

Abstract
A touch screen comprises a display displaying through a front surface of the display and a sensor system. The sensor system is interposed between a back surface of the display and a bottom surface of a housing in which the touch screen is arranged. The sensor system comprises a first electrode assembly and a second electrode assembly and is configured to sense capacitance between the first electrode assembly and the second electrode assembly. The touch screen further comprises a processor being configured to determine based on the sensed capacitance a force resulting from the touch action.
