A capacitive sensor array may include a first set of sensor electrodes and a second set of sensor electrodes. Each of the second set of sensor electrodes may intersect each of the first set of sensor electrodes to form a plurality of unit cells each corresponding to a pair of sensor electrodes including one of the first set of sensor electrodes and one of the second set of sensor electrodes. Each point within each of the plurality of unit cells may nearer to a gap between the pair of sensor electrodes corresponding to the unit cell than to a gap between any different pair of sensor electrodes, and a first trace pattern within a first unit cell of the plurality of unit cells may be different from a second trace pattern within an adjacent unit cell of the plurality of unit cells.

Sensor array with edge pattern

Apparatuses and methods of synchronizing a display driver integrated circuit (DDI) and a touch screen controller (TSC) integrated circuit that are coupled to a display integrated touch panel, such as an in-cell panel, and allowing multi-phase transmit (TX) scanning of the in-cell touch panel. One apparatus includes a DDI configured to receive signals on a video interface from a host processor over a video interface and to drive electrodes of a touch panel. The DDI is configured to receive control signals from a TSC over a control interface to drive different transmit (TX) phase sequences of a TX signal in different sensing interval on the electrodes of the touch panel.
