Abstract:
A touch-sensitive panel is described herein that includes a first sensor layer and a second sensor layer and at least one shield electrode integrated into the first sensor layer and/or the second sensor layer. The at least one shield electrode is operable to cancel parasitic capacitance between at least one sense electrode in the first sensor layer and at least one sense electrode in the second sensor layer. The integrated shield electrode(s) in the first sensor layer and/or the second sensor layer can be used in place of an additional shield layer to combat parasitic capacitance in the touch-sensitive panel, thereby reducing the cost and materials necessary to manufacture the touch-sensitive panel. A touch-screen display that includes such a touch-sensitive panel and a method of operating such a touch-sensitive panel are also described.
