Abstract: A touch screen assembly for an electronic device such as a cell phone or PDA. The touch screen assembly generally comprises a floating lens suspended over the display and, optionally, the keypad to allow a degree of freedom. An underlying thin connecting layer such as a flex film is attached beneath the floating lens, and a plurality (for example, four) differentially-mounted pressure sensors are mounted beneath the floating lens and are electrically connected to the electronic device via the flex film. The pressure sensors are differentially positioned along an x- and y-axis for registering a pressure z from a touch to the lens at each of the four positions, to provide four data sets (x1-4, y1-4, z1-4). Control software then interprets the exact touch-coordinate from the four data sets and generates a control signal. An optional haptic response generator and/or motion sensor are also contemplated.

Abstract: A suspension system for mounting a touch surface of a pressure sensitive touch display or panel. The suspension system comprises a frame and a flexible suspension membrane connected to the touch surface and the frame, the membrane allowing frictionless movement of the touch surface along the z-axis and resisting movement of the touch surface within the x-y plane. At least one force sensor is connected beneath the touch surface, whereby the touch surface is pre-loaded against the at least one force sensor.
