Abstract
A touch sensor panel is disclosed. The touch sensor panel includes a first layer including a plurality of electrodes of a first type that are coupled to respective traces and are configured to operate as touch sensing electrodes during a first time period. The touch sensor panel also includes a second layer including a plurality of electrodes of a second type overlapping with the respective traces of the electrodes of the first type. The electrodes of the second type are configured to operate as guard electrodes for the respective traces of the electrodes of the first type during the first time period and operate as touch sensing electrodes during a second time period.
