Touch sensor back plane ground connection
First Claim
1. A flexible tail of a back plane of a touch sensor panel, wherein the flexible tail has a conductive side and a non-conductive side, comprising:
- a non-critical bend at an end of the flexible tail, wherein the non-conductive side of the flexible tail is on an inner surface of the non-critical bend, wherein a screw through the non-critical bend electrically connects the flexible tail to a ground connection.

Abstract
Touch sensor panels can use touch sensors to detect the presence and location of a touch event. In order for the touch sensors to function reliably, the back plane of the touch sensor panel should be grounded. Supplying this ground connection can provide a uniform electrical reference point from which changes in voltage and capacitance due to a touch event can be measured. Without this ground connection, touch sensors may misrepresent the touch event. Various embodiments of the present disclosure provide different means for providing a ground connection for the back plane of a touch sensor panel. These embodiments are designed to provide a reliable ground connection even in the presence of various failure conditions.
