Abstract

A simplified touch screen system that can sense when an object is held in continuous direct or indirect contact with a transparent substrate of the touch screen system as well as determine a location (e.g., X, Y coordinates) of the object in relation to the transparent substrate. The touch screen system employs capacitance technology to sense whether the object is held in contact with the transparent substrate and acoustic sensing technology to determine a position of the object that is contacting the transparent substrate. The touch screen system requires a reduced number of shielding and isolation layers to be deposited upon the transparent substrate, partially because the touch screen system utilizes a bezel associated with an underlying display to provide shielding against electromagnetic radiation emitted by the display.
