Abstract: Touch panel systems and methods are disclosed that can distinguish temporally overlapping touch inputs from single touch inputs so that valid touch position coordinates can be determined. Touch panel systems and methods of the present invention can distinguish overlapping touches by comparing signal magnitudes to specified thresholds, by comparing the rates of change of signal magnitudes or measured positions to determined parameters, by locating the proximity a calculated location to icons or other such active areas, and the like. Because touch panel systems and methods of the present invention can discriminate single touches from double touches, they can be used in multiple user applications such as multiplayer games as well as in applications that may be subject to rapidly successive or overlapping touch inputs.

Abstract: A method of removably mounting a touch screen assembly, including a glass substrate-based touch screen, to a display panel assembly of a touch screen display system. The method includes providing at least one double-sided, stretch releasable adhesive strip and adhering the strip to the touch screen and the display panel assembly to attach the touch screen to the display panel assembly. The strip is stretch releasable from the screen and the panel assembly to facilitate removal of the touch screen. In one embodiment, the strip includes an adhesive segment defining a longitudinal axis and a non-tacky pull tab extending from the adhesive segment in an angular fashion relative to the longitudinal axis.
