Optimizing pixel settling in an integrated display and capacitive sensing device
Abstract:
An example method of performing capacitive sensing and display updating in an integrated capacitive sensing device and display device includes driving a plurality of sensor electrodes of the capacitive sensing device for input sensing during a blanking period. The method further includes driving a plurality of source lines using a plurality of source drivers during the blanking period to update a first display line of the display device. The method further includes driving the plurality of source lines using the plurality of source drivers during a display update period to update one or more additional display lines of the display device. The method further includes adjusting an operational mode of the plurality of source drivers during the blanking period to equalize display pixel settling between the blanking period and the display update period.
