Abstract: A pressure-sensing touch system for an electronic display includes a plurality of pressure sensors and a controller. Each pressure sensor of the plurality of pressure sensors is configured to generate a signal indicative of pressure applied to a surface of the electronic display. The controller is configured to (i) receive spatial coordinates of a plurality of touch events simultaneously occurring on the electronic display, (ii) select a subset of the plurality of pressure sensors, and (iii) calculate pressure values respectively corresponding to the plurality of touch events based on the spatial coordinates and the signals from the selected subset. The selected subset is a proper subset.

Abstract: Cantilevered displacement sensors with enhanced displacement sensitivity and methods of determining touching forces for multiple touch locations are disclosed. The cantilevered displacement sensors support the touch screen adjacent a touch screen perimeter. A displacement of the touch screen is amplified by a cantilevered member that extends over a proximity sensor. Touching forces at multiple touch locations are determining by performing a fit to the measured displacements based on the touch locations to obtain displacements at all positions of the touchscreen, then relating the displacement of the touch screen at the multiple touch locations to applied distributed loads at the respective multiple touch locations, and then multiplying the applied distributed loads by the corresponding touch-location area.

Abstract: A touch screen system configured to detect a displacement of a cover sheet when pressure or force is applied to the cover sheet upper surface. A light source and photodetector are configured to be in optical communication by reflection of light from the light source from the lower surface of the cover sheet. A displacement of the coversheet changes the amount of reflected light that falls upon the detector. The detector signal can be used to measure the amount of displacement, as well as the time-evolution of the displacement. The touch-screen system can be interfaced with a touch-sensitive display unit to form a display system having both pressure-sensing capability and touch-sensing capability.
