Claim:
1. A processing system for a display device comprising an integrated capacitive sensing device, the processing system comprising: a display driver module comprising driver circuitry, the display driver module configured to be coupled to a plurality of common electrodes configured to be driven for updating a plurality of display lines in a display screen of the display device and performing capacitive sensing, wherein the display driver module is configured to drive a first one of the plurality of common electrodes for updating a first one of the plurality of display lines during a first time period of a first display frame and drive a second one of the plurality of common electrodes for updating a second one of the plurality of display lines during a second time period of the first display frame; and a touch driver module configured to drive a first sensor electrode for capacitive sensing during a third time period of the first display frame, the first sensor electrode comprising at least one common electrode of the plurality of common electrodes, and the third time period being at least as long as the first time period and occurring after the first time period and before the second time period.
