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.

Abstract: An electronic device may include a housing, a display carried by the housing and switchable between a power saving mode and an operating power mode, and a finger biometric sensor carried by the housing and configured to sense an image of an object adjacent thereto. The electronic device may also include a device cover carried by the housing and configured to be movable between an open position exposing the finger biometric sensor and a closed position covering the finger biometric sensor. The device cover may include a cover panel and an electrically conductive member carried by the cover panel adjacent the finger biometric sensor when in the closed position. A controller may be coupled to the finger biometric sensor and configured to determine when the electrically conductive member is adjacent the finger biometric sensor, and selectively switch the display between the power saving mode and the operating power mode based thereon.
