Patent ID: 8907921

Claim:
A processing system for a display device with an integrated capacitive sensing device comprising: a driver module configured to be communicatively coupled to a plurality of common electrodes configured for capacitive sensing and display updating, the plurality of common electrodes comprising a first set of common electrodes and a second set of common electrodes, the first set of the common electrodes including at least one common electrode included in the second set of the common electrodes and at least one common electrode not included in the second set of the common electrodes, the driver module configured for: driving the plurality of common electrodes for display updating during a first display frame; driving the first set of common electrodes for capacitive sensing during a first portion of the first display frame, wherein at least one common electrode included in the second set of the common electrodes is not driven for capacitive sensing during the first display frame; and operating the plurality of common electrodes in a substantially non-modulating manner for interference sensing during a second portion of the first display frame; a receiver module configured to be communicatively coupled to a plurality of receiver electrodes, the receiver module configured for: receiving first resulting signals during the first portion of the first display frame; and receiving second resulting signals during the second portion of the first display frame; and a determination module configured for determining at least portion of a first capacitive frame based on the first resulting signals and an interference measurement corresponding to the first capacitive frame based on the second resulting signals.
