<p>A touch sensor panel is disclosed including the use of ground guards or ground isolation bars to improve the touch event detection capabilities of the touch sensor panel. Ground isolation bars can be formed between connecting traces and adjacent sense lines to shunt near-field lines to ground and reduce unwanted capacitive coupling between the connecting traces and the sense lines. Ground guards can be formed between the drive and sense lines to partially or fully surround a sense line and shunt near-field lines to ground and improve the touch event detection capabilities of the sensor.</p> |
