PROBLEM TO BE SOLVED: To improve the touch detection capabilities of a capacitive touch sensor panel.SOLUTION: A touch sensor panel uses ground guards or ground isolation bars to improve the touch event detection capabilities thereof. The ground isolation bars can be formed between connecting traces and adjacent sense lines to shunt near-field lines to ground and to reduce unwanted capacitive coupling between the connecting traces and the sense lines. The ground guards can be formed between drive lines and the sense lines to partially or fully surround a sense line to shunt near-field lines to ground and improve the touch event detection capabilities of the sensor. |
