Abstract
In an example, a processing system for an integrated display device and capacitive sensing device includes driver circuitry and a driver module. The driver circuitry is configured for coupling to a plurality of source lines and a plurality of sensor electrodes, where each of the plurality of sensor electrodes comprises at least one common electrode configured for display updating and capacitive sensing. The driver module is coupled to the driver circuitry and configured to drive the plurality of sensor electrodes for capacitive sensing during a first non-display update period that occurs between first and second display line update periods of a display frame, where the non-display update period is at least as long as one of the first and second display line update periods. The driver module is further configured to operate each of the plurality of source lines to reduce display artifacts during the non-display update period.
