Patent ID: 8766950

Claim:
An input device comprising a display device having an integrated capacitive sensing device, the input device further comprising: a plurality of source driver electrodes; a plurality of gate electrodes; a plurality of sensor electrodes, wherein each sensor electrode of the plurality of sensor electrode comprises one or more common electrodes of a plurality of common electrodes the plurality of common electrodes configured to be driven for display updating and input sensing; and a processing system coupled to the plurality of source driver electrodes, the plurality of gate electrodes and the plurality of sensor electrodes, wherein the processing system is configured to: drive a first sensor electrode and a second sensor electrode of the plurality of sensor electrodes with a first modulated signal during a first period to determine changes in capacitive coupling between the first sensor electrode and the second sensor electrode and an input object; drive a first gate electrode of the plurality of gate electrode with a second modulated signal during a second period and drive a first source driver electrode of the plurality of source driver electrodes with a third modulated signal during a third period, wherein the first period, the second period and the third period at least partially overlap and wherein the first modulated signal, the second modulated signal and the third modulated signal are based on a modulated reference signal.
