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 (x, y, z). 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. When used in a smaller electronics device such as a cell phone or PDA the touch screen sensor technology of the present invention is exceedingly thin and is capable of modular assembly for more-or-less 'snap-in' construction.
