Data processing device comprising a touch screen and a force sensor

摘要

A data processing device comprises a touch screen with a touch position sensor. The position sensor is suitable to detect a touch position on the screen from a change in a current pattern in a conductive panel. The device also comprises a touch force sensor provided with a second conductive panel which extends substantially parallel to the touch screen. The screen is at least partly movable relative to the second panel in a direction transversely of the second panel. The force sensor is suitable to determine a force from a capacitance value between the touch screen and the second panel. The device is suitable for the combined processing of the position and force detected in response to touching.
